                            PART I



ITEM 1.  	BUSINESS

General

    Research Frontiers Incorporated ("Research Frontiers" or
the "Company") develops and licenses its patented suspended
particle device ("SPD-Smart") light-control technology to other
companies that manufacture and market either the SPD-Smart
chemical emulsion, light-control film made from the chemical
emulsion, lamination services, electronics to power end-
products incorporating the film, or the end-products themselves
such as "smart" windows, skylights and sunroofs. Research
Frontiers currently has 37 companies that, in the aggregate, are
licensed to serve four major SPD-Smart application areas
(aerospace, architectural, automotive and marine products) in
every country of the world.

     Research Frontiers was incorporated in New York in 1965
to continue early work that Dr. Edwin Land, founder of Polaroid
Corporation, and others had done in the area of light-control
beginning in the 1930s. Research Frontiers was reincorporated
in Delaware in 1989. Since 1965, Research Frontiers has
actively worked to develop and license its own SPD technology,
which it protects using patents, trade secrets and know-how.
Although patent and trade secret protection is not a guarantee of
commercial success, Research Frontiers currently has over 500
patents and pending patent applications throughout the world
protecting its technology, positioning it as a leader of advanced
light, glare and heat control for windows and other glazing
products.

     SPD-Smart products use microscopic light-absorbing nano-
particles that are typically suspended in a film. These particles
align when an electrical voltage is applied, thus permitting light
to pass through the film. Adjustment of the voltage to the SPD
film gives users the ability to instantly, precisely and
consistently regulate the amount of light, glare and heat passing
through the window, skylight, sunroof, window shade or other
SPD-Smart end-product.

     SPD light-control technology may have wide commercial
applicability in many types of products and industries where
variable light transmission is desired, such as:

-  "smart" windows, skylights, partitions, doors, and
   sunshades for the architectural, aircraft, marine,
   automotive and appliance industries;
-  variable light transmission sunglasses, goggles, visors
   and other eyewear;
-  variable light transmission automotive sunroofs,
   sunvisors and rear-view mirrors; and
-  flat panel information displays for use in billboards,
   scoreboards, point-of-purchase advertising displays,
   traffic signs, computers, telephones, PDAs and other
   electronic instruments.

    Research Frontiers considers the SPD industry to be in the
initial phase of growth and sales of SPD-Smart products for
aircraft windows, smart windows and skylights for homes and
offices, sunroofs and side-and rear-windows for cars, boats,
busses and other transportation vehicles. Some of these early
sales and uses have been commercial installations and some
have involved concept and test installations by licensees and
their customers (see "Trends and Recent Developments"
below). Some of our licensees consider the stage of
development, product introduction strategies and timetables,
and other plans to be proprietary or secret, and as such cannot
be disclosed by Research Frontiers until such licensees, or their
customers, make their own public announcements or product
launches.

    In addition to the near-term product applications listed
above, prototypes of SPD-Smart flat panel displays, eyewear,
and self-dimming automotive rear-view mirrors have been
developed. These prototypes demonstrate the feasibility and
operation of the products they relate to, but in some cases may
need additional product design, engineering or testing before
commercial products can be introduced.

    Recent progress with regard to market development and
commercialization activity has been the result of focused and
active efforts by Research Frontiers and its key production and
end-product licensees who have invested in product
development and improvements, production facilities, increased
production capacity, durability, performance testing, quality
control and assurance, and marketing programs. Licensees
supplying film to end-product licensees have recently announced
increases in their production capacity, or plans to so so, in
order to prepare for potentially large and developing markets
for SPD-Smart products. Research Frontiers believes that with
the normal progression of product and manufacturing
improvements, and as licensees become more experienced at the
lamination, fabrication and installation of SPD-Smart products
for various applications, the adoption rates for SPD-Smart
products will grow and accelerate, resulting in an increasing
stream of royalty income for the Company.

     As part of their marketing and branding programs, many of
our licensees have developed their own trademarks for SPD-
Smart emulsion, film, and end-products and these are listed in
their respective press releases, product brochures, advertising
and other promotional materials. Research Frontiers uses the
following trademarks: SPD-Smart(tm), SPD-SmartGlass(tm),
VaryFast(tm), SPD-CleanTech(tm), SPD Clean Technology(tm),
SmartGlass(tm), The View of the Future - Everywhere you
Look(tm), Powered by SPD(tm), Powered by SPD-CleanTech(tm),
Powered by SPD Clean Technology(tm), SG Enabled (tm),SPD Green
and Clean(tm), SPD On-Board(tm), Speed Matters(tm), and Visit
SmartGlass.com - to change your view of the world(tm).

     In each of the last three fiscal years the Company has
devoted substantially all of its time to the development of one
class of products, namely SPD-Smart light-control technology,
and therefore revenue analysis by class is not provided herein.

     The Company does not believe that future sales will be
seasonal in any material respect. Due to the nature of the
Company's business operations and the fact that the Company
is not presently a manufacturer, there is no backlog of orders for
the Company's products.

     The Company believes that compliance with federal, state
and local provisions which have been enacted or adopted
regulating the discharge of materials into the environment, or
otherwise relating to the protection of the environment, will not
have a material effect upon the capital expenditures, earnings
and competitive position of the Company. The Company has no
material capital expenditures for environmental control
facilities planned for the remainder of its current fiscal year or
its next succeeding fiscal year.

    On March 10, 2010 the Company had eleven full-time
employees, five of whom are technical personnel, and the rest
of whom perform legal, marketing, investor relations, and
administrative functions. Of these employees, two have
obtained doctorates in chemistry, one has a masters degree in
chemistry, one has extensive industrial experience in
electronics and electrical engineering, and one has majored in
physics. Three employees also have additional postgraduate
degrees in business administration, including one doctorate in
organization and management. Also the Company's suppliers
and licensees have people on their teams with advanced degrees
in a number of areas relevant to the commercial development of
products using the Company's technology. The success of the
Company is dependent upon, among other things, the services
of its senior management, the loss of which could have a
material adverse effect upon the prospects of the Company.

Industry Trends

    While economic activity around the world is still recovering
from a severe downturn, there are also favorable converging trends in
the major near-term markets for SPD-Smart products. These
trends are gaining momentum and strength. In both public and
private sectors across the world, there are substantial efforts
targeted toward the promotion and use of energy efficient
materials, including those used in windows and other glazings
for homes, buildings, automobiles, aircraft and boats. For
example, as part of its sustainable design strategies, the
architectural community is actively inreasing the use of
"daylight harvesting" systems to more effectively capture and
control natural light as part of energy reduction strategies
to offset electricity used by artificial lighting. There also
is a growing trend toward the use of more glass in all of the
near-term SPD markets. In addition to design, aesthetic and
other benefits, this expanded use of glass also supports a
growing body of research which finds that the presence of
natural light improves the well-being and productivity of
individuals. Products using SPD-Smart light-control
technology can play an important role in supporting
these converging global trends.

    For architectural applications, a number of market forces
are having an upward influence on demand for SPD-Smart
glass. Many architects are specifying more glass in their designs
to support building occupants' sense of connectedness to the
outside environment. Also significant is the heightened
attention to energy efficiency in both commercial and
residential buildings. Various studies indicate that buildings
in the United States and Europe now account for an estimated
39-40% of total energy use and upwards of 70% or more of
electricity consumption. Many architects and building owners
are striving for sustainable, "green" buildings that are
highly energy-efficient, reduce environmental impact, and
improve occupant health and well-being. In addition, the
design community is increasingly interested in advanced
daylighting systems in buildings that lower electrical
lighting usage and reduce heating and cooling loads.
Because of this, the ability to control light, glare and heat
in these building applications is very important and advanced
solutions often are needed to optimize operating efficiencies.
SPD-Smart technology, especially when integrated with
intelligent building systems, provides effective shading, glare
control and heat management solutions for offices and homes.
As a result, architects and developers are now specifying SPD-
Smart products in their projects, and both the number and size
of these projects are increasing.

    In the automotive industry, global trends include the
introduction of larger sunroofs and panoramic roof panels in
transportation vehicles, and a higher percentage of these
vehicles having a sunroof or using more glass in the roof. In
addition, automobile manufacturers are beginning to introduce
"cielo" glass systems where the windshield of the vehicle joins
with the glass in the roof of the vehicle to form one continuous
piece of curved glass. The SPD-Smart component of these cielo
systems can start with the blue band on the top of the
windshield (the rest of the windshield would not use any kind of
dark tint because regulations require that the main part of the
windshield not have less than 70% light transmission at all
times) and extend back to encompass the entire glass roof.
Some automakers have recently begun to incorporate SPD-
SmartGlass in concept vehicles, with some of these concept
vehicles being exhibited at major auto shows, and a growing
number of automakers are developing SPD-Smart glass products
for production vehicles as well. SPD-SmartGlass has also been
shown in armored automotive glass applications, and a new
market is also developing for personalized custom conversions
of automobiles for owners who wish to express themselves
through the design of the cars they own and/or drive.

    In the aerospace industry there is also a trend towards
larger windows, most notably in the "transport category"
(commercial passenger aircraft) segment. The world's two
largest aircraft manufacturers have announced their interest to
include electronic smart window shades in their aircraft, and
strong interest exists at other OEMs as well. Electronic aircraft
window shades may use SPD technology, or may use other
smart window technologies such as liquid crystal or
electrochromic technology. For use in aircraft, SPD-Smart
window shades are made of plastic instead of glass to save
weight for a given window thickness, to avoid breakage
risks, and to avoid using a protective containment shroud
needed if glass is used. The Company believes its SPD
technology offers important performance advantages over
other technologies including weight-savings and faster,
more uniform response time. To date, SPD technology is also
the only commercially available light-control smart window
technology known to have passed the stringent safety and
durability tests required by the aviation industry and
received a Supplemental Type Certificate (STC) from the
Federal Aviation Administration. Today SPD-Smart window
shades are flying in various aircraft including those used
in general aviation (private and business aircraft) and
military aviation. SPD-Smart window shades are also
beginning to be used in commercial passenger aircraft.
During the fourth quarter of 2009, two leading companies
making electromechanical window shades announced new
products that incorporate SPD window shades into their
designs.

    In the marine application for SPD-Smart technology, to
satisfy various objectives, many yacht manufacturers currently
employ less than ideal glazing solutions. For example, some
report having to use as many as five different types of glass in a
typical yacht to satisfy diverse glazing needs. SPD-Smart
window technology can reduce the number of different types of
glass used in these yachts because of its increased functionality
and superior performance and versatility. SPD-SmartGlass has
appeared in glass designed for yachts and other marine vessels.
Because boat operators experience substantial exposure to
direct sunlight, SPD-Smart products provide an innovation that
allows these operators to manage incoming light, glare and heat
while achieving privacy or maintaining one's view as needed or
desired.

    Products using SPD-Smart technology continue to be
exhibited at trade shows, conferences, and industry events, with
such products not only being exhibited by our licensees but also
by their customers and by original equipment manufacturers.
While there can be no assurance that these trends will continue,
to the extent that they do continue, each should have a
beneficial effect on future fee income for the Company.

    In June 2008, The Freedonia Group, a highly regarded
independent market research firm serving the glass industry and
others, announced the release of its 2008 Advanced Glass
Study. In that study, Freedonia projected a compound annual
growth rate in United States smart glass demand through 2017
of 10.2%, a level more than twenty times the rate for flat glass
demand overall in the U.S. Further, in the narrative
accompanying the release of this study, Freedonia shared these
very positive comments about SPD technology:

    "[D]emand for smart glass is expected to finally have a
significant impact outside of the electrochromic mirrors and
liquid crystal display privacy glass that have been available for
some years. The much-awaited commercial roll-out of
suspended particle device (SPD) smart glass technologies is
now expected to occur, sparking well above average growth for
the category through 2012."

Historical Background and Recent Developments

SPD-Smart Film Production

     The essence of SPD-Smart end products such as smart windows
is the SPD-Smart light-control film used to vary the tint of
glass or plastic. Initially the sole manufacturer of this film
was SPD Inc., a subsidiary of Hankuk Glass Industries, a former
licensee of Research Frontiers. In April 2004, SPD Inc.
announced that it was ceasing its business activities. As a
result, sales of SPD-Smart products by licensees of the Company
during most of 2004, 2005 and 2006 were curtailed as these
licensees filled certain customer orders out of limited existing
inventory of SPD-Smart light control film made by SPD Inc. while
awaiting production of the next-generation, emulsion-based
SPD-Smart light control film with its improved performance
characteristics.

     After this hiatus in SPD film availability, a number of
significant events began in 2007 and continue through 2010 that
have helped the development of the Company's business worldwide.
In early 2007, our licensee Hitachi Chemical began producing their
initial SPD-Smart light-control film on their first factory line.
During the second half of 2009, Hitachi Chemical announced that
they had begun mass production on their new, larger capacity,
production line and expanded their annual production capacity
to 400,000 square meters (over 4.3 million square feet).
Unlike prior production lines, Hitachi's new production line is
dedicated exclusively to the production of SPD-Smart film. In
July 2009, Hitachi Chemical launched its web site dedicated to
its SPD-Smart light control film and during 2009, Hitachi Chemical
has outlined in its press releases and public presentations that
it plans to "accelerate the use of SPD film, which holds
significant potential for growth" and notes that "SPD film is
positioned as one of the key emerging products promoted by Hitachi
Chemical to become a future leading product for the company."
Hitachi Chemical gave a presentation to analysts dated October
30, 2009 regarding Hitachi Chemical's performance during the
first half of the year and highlighted management issues for
the second half. In that presentation, Hitachi Chemical noted
that it is targeting SPD film sales of 5 billion yen
(approximately $53.4 million) in 2012. Customers for Hitachi
Chemical's SPD-Smart film are end-product licensees of Research
Frontiers. These companies receive the film, laminate it into
glass or plastic, and then fabricate end-products sold into
various industries. End-product licensees pay Research
Frontiers a royalty on the sale of these end-products that
typically ranges from 10-15%.

      In addition to Hitachi Chemical, two companies are
currently making or developing SPD-Smart light control film
under license from Research Frontiers using SPD-Smart emulsion
produced by our licensee DIC Corporation (formerly known as
Dainippon Ink and Chemicals). These two companies are licensed
to sell SPD-Smart light-control film to other licensees of
Research Frontiers. One company in Italy, Isoclima, is also
licensed by Research Frontiers to make and sell architectural
and automotive end-products worldwide. In February 2010,
Research Frontiers also licensed Australia's ID Research Pty
Ltd. (the parent company of IGlass Pty Limited) to make and
sell SPD-Smart film worldwide, and to make and sell SPD-Smart
architectural smart window products in Australia, New Zealand
and South Africa.

SPD-Smart Aircraft Products

     Research Frontiers' licensee InspecTech Aero Service Inc.
continues to penetrate the OEM and retrofit markets for
SPD-Smart window shades.  Building on previously announced
milestones regarding the approval by Hawker Beechcraft
Corporation of InspecTech window shades for aftermarket
conversions of King Air aircraft, and receiving a Supplemental
Type Certificate (STC) for all models of King Air aircraft by
the FAA, InspecTech and the companies that they sell products
to are working with a growing number of aircraft manufacturers
and their customers and are selling SPD-Smart window shades
for various models of fixed wing aircraft and helicopters.
InspecTech's SPD-Smart window shades have also been installed
in selected areas on all A380 aircraft delivered by Airbus to
Qantas Airlines to date, making SPD-Smart window shades the
first and only electronically dimmable window shade flying on
commercial airlines.

     In October 2009, at the NBAA Annual Meeting and Convention,
in addition to featuring its SPD-Smart window shades, InspecTech
Aero Service unveiled its Smart Cabin Automated Dimming System
(SCADS(tm)) for these window shades. With this new complementary
system, in addition to the light, heat and glare control
SPD-Smart window shades bring to cabin windows, the product has
integrated  intelligence into airframe systems and adds the
capability to interface the SPD-Smart window shades with other
cabin systems such as Cabin Management Systems and In-Flight
Entertainment systems, providing unprecedented smart
automation of cabin light-management.

     InspecTech Aero Service markets and offers its SPD-Smart
window shades through a variety of programs including working
directly with aircraft OEMs, advertising campaigns, targeted
direct marketing campaigns and trade show exhibitions. In
addition, InspecTech is building out a marketing and
distribution infrastructure by establishing strategic
partnerships with OEM service organizations, aircraft
refurbishment and completion centers, and aircraft component
suppliers marketing products that include InspecTech's SPD-Smart
window shades as part of their product offering. At the
October 2009 NBAA Annual Meeting and Convention, in addition
to InspecTech, two other leading window shade manufacturers
working with InspecTech unveiled window shading systems that
included InspecTech's SPD-Smart window shades.

     In January 2010, Research Frontiers further expanded its
presence in the aircraft industry by licensing Vision Systems
of France to make and sell in Europe SPD-Smart products for
aircraft. The Vision Systems license also covers the manu-
facture and sale of SPD-Smart products for trains, recreational
vehicles, busses, trucks, mobile cranes and construction vehicles.

SPD-Smart Automotive Products

     Research Frontiers and its licensees are currently working
with multiple automotive manufacturers to introduce SPD-Smart
windows, sunroofs and roof systems on both concept and production
vehicles. The number of such automotive manufacturers has been
growing.

     In September 2008, the automotive glass business of PPG
Industries (now known as Pittsburgh Glass Works, LLC), was
licensed to make SPD-Smart automotive glass products, including
windows, sunroofs and roof glass systems. Pittsburg Glass Works
(PGW) is North America's largest automotive glass producer.
PGW cited the importance of this work with SPD-Smart automotive
products in their October 2009 press release highlighting
milestones achieved during the past year. A similar license
agreement was entered into by Pilkington Group Limited, a
subsidiary of Nippon Sheet Glass, the world's second largest
glass manufacturer. The Company's large automotive glass licensees
account for the vast majority of all glass produced for the
automotive market throughout the world.

      At the 40th Tokyo Motor Show 2007, Hino Motors, Ltd., a
subsidiary of Toyota Motor Corporation, featured a new concept
S'elega Premium motorcoach with variable tint side windows using
Research Frontiers' patented SPD-Smart light-control technology.
The S'elega Premium on display at the Tokyo Motor Show had five
large SPD-Smart side window panels with over 11 square meters of
curved glass (more than 120 square feet) produced by Research
Frontiers licensee Asahi Glass Company. Asahi Glass Company is
the world's largest glass company. This vehicle was part of a
process to validate Asahi Glass' production of SPD-Smart glass
for the higher-volume passenger car market and details of such
work has not yet been publicly announced by Asahi or their
customers.

      Since the introduction in late 2007 by Research Frontiers
licensee American Glass Products (AGP) of their Vario Plus-Sky
SPD-Smart products at the SEMA show in Las Vegas, AGP has become
active in offering SPD-SmartGlass to the automotive aftermarket,
as well as working with various OEM customers for high-volume
production vehicles.  AGP's Vario Plus-Sky brand of variable
light transmission glass using Research Frontiers' patented
SPD-Smart technology enables users to instantly, precisely and
consistently control the amount of light, glare and heat passing
through glass or plastic. In addition to the number of vehicles
that AGP has developed SPD-Smart glass for in the aftermarket,
AGP can also custom manufacture these products for virtually any
vehicle. In October 2008, AGP also announced a strategic
technology partnership with DiMora Motorcar, and its plans to
provide its Vario Plus-Sky brand of SPD-SmartGlass(tm) for
DiMora Motorcar's Natalia SLS 2 sport luxury sedan. At the
November 2009 SEMA Show, AGP partnered with its customer Elite
Auto Tune to feature a Mercedes S550 with rear side windows that
use SPD light-control technology. Research Frontiers licensee
SPD Control Systems Corp. developed and supplied the dynamic
controller for these smart windows. In addition to its debut
in Las Vegas at the 2009 SEMA Show, this SPD-Equipped vehicle
has also appeared at a major car event in Miami in February,
and is scheduled to appear in 2010 at subsequent automotive
events in various additional cities.

      While the highest volume market for which SPD-Smart
technology is being developed is new car production by the world's
automakers, the aftermarket upgrade market presents near-term
opportunities in the automotive market. Within the automotive
market, a potentially significant additional market is the
armored glass market. Armored glass (sometimes referred to
as "transparent armor" and "bullet-resistant glass") encompasses
the military, non-military government, and civilian markets.
While each of these submarkets have their own unique
characteristics, some common characteristics include high price
points, reduced price sensitivity, fast development cycles to
incorporate new glass into vehicles, and the ability to
incorporate SPD-Smart glass as an aftermarket upgrade. In
addition, SPD-Smart technology in this market not only provides
the usual benefits of light-control and UV blockage, but also
adds enhanced security by introducing darker tints and privacy.
A number of the Company's licensees such as American Glass
Products, GKN Aerospace, Isoclima and Pittsburgh Glass Works
are recognized industry leaders in the armored glass market and
have developed and/or exhibited publicly armored SPD-Smart glass.

      Our market research suggests that about 20,000 to 25,000
non-military vehicles (utilizing between approximately 215,000 to
800,000 square feet of glass) are built annually, either as
specialty models by the automobile OEMs or by aftermarket
converters, who account for the majority of sales of such
vehicles. Given the relatively short development cycles
(especially in the aftermarket segment), good price points, and
in light of the ongoing work being done by our licensees in this
field for specific government and civilian customers, armored
vehicles have the potential to become an important source of near-
term royalty revenue to Research Frontiers. Public activity in
this armored-glass market has grown:

      In February 2008, GKN Aerospace Transparency Systems
acquired a license covering SPD-Smart armored glass for vehicles.
GKN is a world leader in armored transportation vehicles for both
military and civilian vehicles. Since then, GKN has exhibited their
armored SPD-Smart automotive glass at various military and industry
trade shows. In September 2009, GKN announced that it had been
awarded a $425,000 contract by the Combating Terrorism Technical
Support Office (CTTSO) of the United States Department of Defense
to develop instantly dimmable SPD-Smart bullet resistant windows.

      In October 2008, licensee Isoclima S.p.A. debuted at Security
Essen 2008 and at Glasstec 2008 a Fiat Croma automobile outfitted
by Isoclima with SPD-SmartGlass(tm). The Fiat Chroma featured five
panels of Isoclima S.p.A.'s Cromalite(r) SPD-SmartGlass including
two rear sidelites, two rear quarterlites and one backlite. The
SPD-Smart glass for this vehicle uses remote control operation
to instantly adjust light and glare coming through the windows.
Isoclima also had a broader exhibit at these shows demonstrating a
BMW Series 7 armored glass rear side window and other automotive
products using its Cromalite(r) brand of SPD-Smart glass. Isoclima
also exhibited its Cromalite(r) brand of SPD-Smart glass at various
trade shows and other venues in 2009.

SPD-Smart Architectural Products

     SPD-Smart windows, skylights and partitions offer various
benefits in architectural applications. During 2009, independent
tests were conducted by DSET Laboratories, a division of Atlas
Material Testing Technology, in accordance with ASTM and ASHRAE
testing and calculation protocols. These test results demonstrate
that SPD-Smart windows have excellent solar heat rejection and
control capabilities. Additional energy savings are possible using
SPD-Smart windows as part of a "daylight harvesting" strategy in
facilities management. Various private and public installations
of SPD-SmartGlass are appearing in the residential and commercial
markets, and additional projects specifying SPD-SmartGlass are
currently going out for public bid.

     In December 2007 AGC Flat Glass Europe (a wholly-owned
subsidiary of Asahi Glass, the world's largest glass company)
acquired a new license covering SPD-Smart architectural window
applications.

     In September 2008, Research Frontiers licensee SmartGlass
International launched its line of SPD-SmartGlass architectural
window products at the 100% Detail show in London, England. The
show focuses on the latest developments in sustainability,
innovation and design for the building environment. SmartGlass
International produces its SPD-SmartGlass products at their new
and expanded manufacturing facility in Dublin, Ireland which
houses the company's design, tempering, laminating and quality
control operations, as well as its product showroom. SmartGlass
International also announced the recent completion of a multi-
panel SPD-Smart roof-lite project in London. At the 100% Details
show, SmartGlass International's SPD-Smart products won the
show's Most Innovative Building Product Award. SmartGlass
International also featured SPD-Smart glass products at various
exhibitions, conferences and other events in Europe during 2009.
In early 2010, SmartGlass International opened up a London
showroom featuring its smart glass products. SmartGlass
International was originally licensed for SPD-Smart
architectural glass products in the UK and Ireland. In June
2009, SmartGlass International expanded their license to cover
all areas of the world outside of North America. As part of
this expansion, SmartGlass International also granted the
SCHOTT Group rights to sell SmartGlass International's SPD-Smart
products in all areas of the world outside of the UK and Ireland
(which is currently handled directly by SmartGlass International)
and North America.

     In February 2009, Research Frontiers' licensee Innovative
Glass Corp. announced the completion of the world's largest
SPD-Smart glass project at Indiana University using next-
generation SPD-Smart light control film. The project used almost
800 square feet of SPD-Smart glass in 59 interior and nine large
exterior smart glass panels. Innovative Glass also completed other
residential and commercial SPD-Smart glass installations in 2009,
and also appeared, with Research Frontiers, on the Discovery
Channel's Mega Engineering program which began airing in the US
in September 2009, and internationally since that time.

     SPD Control Systems Corporation, a licensee of Research
Frontiers, has developed and is selling for the automotive market
its 8-window Tintmaker controller. This controller, which was
specifically designed for SPD-Smart windows and initially designed
for the automotive market, is also being adapted for use in the
architectural, marine and aerospace industries. The Tintmaker
controller allows for the control of single or multiple SPD-Smart
windows by several methods including manual dimmer or slider
controls, automatic control from on-board systems, and self-
regulated control via sensors. In 2008, SPD Control Systems
announced that it was awarded a $580,000 matching funds contract
from the New York State Energy Research and Development Authority
(NYSERDA) for the development and demonstration of a control
system for architectural SPD-Smart window products. SPD Control
Systems' Wireless Building Control System include 8-window
controllers (leveraging the company's controller designs for
the automotive industry), advanced sensors, dynamic tinting
algorithms and other distinctive operating features including
an interface with other building services such as heating,
ventilation and air conditioning (HVAC) and lighting. SPD
Control Systems lectures and presents its electronic
controllers and demonstrates SPD-Smart window technology at
various trade shows and conferences, including those focused
on energy efficiency in architectural applications.

     Prelco, a licensee of Research Frontiers Inc. exhibited
SPD-SmartGlass at the 25th annual Build Boston show in November
2009. Build Boston is the largest regional convention and tradeshow
for the design and construction industry. Prelco is an ISO 9001
company and is the leading manufacturer of industrial,
transportation and architectural safety glass in Canada and the
northeastern United States. Research Frontiers licensee Hitachi
Chemical Company, Ltd. produced and supplied its high-performing
SPD film to Prelco, which does its own lamination.

     In February 2010, ID Research Pty Ltd (IDR) (the parent
company of iGlass Pty Limited) acquired a license from Research
Frontiers Inc. granting it the right to manufacture and sell
SPD-Smart architectural end-products in Australia, New Zealand
and South Africa. The license also grants ID Research Pty Ltd
the worldwide right to manufacture and sell SPD emulsion and
film to end-product licensees of Research Frontiers. The license
follows a $1.5 million grant to ID Research Pty Ltd from the
Government of Victoria's Science Agenda (VSA) Investment Fund
for "Electro Responsive Material Coatings for Switchable
Automotive Tinted Glass."

     Dr. George Elvin, Director of Green Technology Forum, is
featuring SPD-Smart light-control technology in a series of
international talks and courses on emerging green technologies.
Dr. Elvin is a well-known advisor, speaker and author on emerging
technologies and has an extensive academic background.


Marketing Activities and Licensee Support

     In addition to supporting the efforts of its licensees,
Research Frontiers also recognizes the need to develop the SPD
industry as a whole. As such, the Company continues to plan and
execute complementary programs that build awareness and interest
in smart glass generally and demand for SPD-Smart technology
specifically. These programs include presentations at various
general industry conferences, participation in panel presentations
and discussions hosted by academia, development of trade
association educational materials, and presentations to architects,
designers, and other influential specifiers.

    The Company's market development department has a number of
other initiatives in place. To help guide and prioritize its
technical and marketing investments, the Company has also
retained outside strategic marketing and other consultants to
help generate increased short and medium term market penetrations
for each of the major markets for the Company's light-control
technology, and to provide support and guidance to the Company's
licensees worldwide.

     The Company has emerged as the world's leading resource for
market research information on the subject of smart glass.
Research Frontiers lectures and presents at industry conferences
in areas of energy efficiency and daylight harvesting, and has
published independent test data, shared the results of its
research studies and test data with industry and the media,
posted various reference materials to the Company's website
for global dissemination, and published presentations, data
and bylined articles.

     Research Frontiers maintains an active role with various
standards-setting organizations. These organizations include
ASTM International and the National Fenestration Rating Council
(NFRC), both of which have had or continue to have active
committees developing standards for smart glass.

     In addition to Research Frontiers providing overarching
support of licensees' sales efforts by developing the SPD
industry as a whole, leveraging its prominence as a leading
resource on the topic of smart glass, and maintaining an active
role with standards organizations, Research Frontiers also
supports licensees' marketing and sales efforts directly.
Activities include advising and assisting with branding
strategies and advertising campaigns, website development
and other marketing materials, joint presentations to
prospective customers, and additional support. As a focal
point of interest in smart glass, resulting in many consumer
and business inquiries, Research Frontiers has a highly active
referral program resulting in qualified customer leads being
sent to licensees.

     As part of this mission to develop the industry and to
support our licensees' acquiring specific SPD projects, in
March of 2009 Research Frontiers announced the completion of
the SPD-SmartGlass Design Center. Research Frontiers and its
licensees have begun to host a series of events at this new
facility. This center, which is also configured as an
interactive and energy-efficient "smart" executive office and
conference room, is located at the Company's corporate headquarters
in Woodbury, New York. The SPD-SmartGlass Design Center features
leading-edge SPD-Smart windows of different sizes (some floor-to-
ceiling) and framing materials. It has a multi-functional
electronic controller system for manual, remote, and automatic
smart glass switching, and includes a large enclosed area where
private meetings and video presentations can be held. An
interactive exhibit was also competed in 2009 adjacent to the
Design Center to provide guests with a history of smart glass,
and also to showcase early generations and state-of-the-art
examples of SPD-Smart products. This interactive area also
contains other types of smart glass, such as those using
liquid crystal and electrochromic technologies, allowing
users to operate and experience first-hand the differences
in performance characteristics of different types of
smart glass.



Licensees of Research Frontiers

     Currently, the Company's 37 licensees are categorized into
four main areas: materials for making films (emulsions); film;
lamination of film to glass or plastic, and end-products.
Emulsion makers produce and combine the necessary materials
(i.e. SPD particles and various liquids and special polymers)
from which SPD-Smart films are made. The film makers coat a
thin layer of emulsion between two sheets of plastic film, each
of which has a transparent conductive coating. This emulsion is
then partly solidified to form an SPD film that allows users to
control the amount of light, glare and heat passing through this
film. The end-product licensees then integrate this film into a
variety of SPD-Smart products, or make electronic systems to
control such SPD-Smart products. Some of these end-product
licensees do their own lamination of the SPD light-control film
to glass or plastic, and some outsource this lamination to other
companies.The names of this growing list of licensees, and the
year that their license agreements were entered into, are
contained in the Exhibit Section of this Annual Report on
Form 10-K.

     Licensees of Research Frontiers who incorporate SPD
technology into end-products will pay Research Frontiers a
royalty of 5-15% of net sales of licensed products under license
agreements currently in effect, and may also be required to pay
Research Frontiers fees and minimum annual royalties.
Licensees who sell components (such as SPD emulsion or film)
or lamination services to other licensees of Research Frontiers
do not pay a royalty on such sale or service, and Research
Frontiers will collect a royalty from the licensee incorporating
these components into their own SPD-Smart end-products.
Research Frontiers' license agreements typically allow the
licensee to terminate the license after some period of time, and
give Research Frontiers only limited rights to terminate before
the license expires. The licenses granted by the Company are
non-exclusive and generally last as long as Research Frontiers
patents remain in effect. Due to their bankruptcy filings or
other termination of their general business activities or for
other reasons, the Company does not believe that Polaroid
Corporation, Kerros Limited, ThermoView Industries, BRG Group,
SPD Technologies, SPD Systems and Film Technologies
International are pursuing business activities with respect to
SPD technology. Also the Company and licensee N.V. Bekaert,
S.A mutually agreed to terminate their license agreement during
2008 for reasons unrelated to SPD technology. Some of the
Company's other licensees are currently inactive with respect
to SPD technology, but may hereafter become active again. To
date, the Company has not generated sufficient revenue from
its licensees to profitably fund its operations. Copies of
all of the Company's license agreements are included as
exhibits to the Company's periodic reports filed with the
Securities and Exchange Commission.

     Although the Company believes based upon the status of
current negotiations that additional license agreements with
third parties will be entered into, there can be no assurance that
any such additional license agreements will be consummated,
or of the extent to which any current or future licensee of the
Company will produce or sell commercial products using the
Company's technology or generate meaningful revenue from
sales of such licensed products.

     The Company plans to continue to exploit its SPD-Smart
light-control technology by entering into additional license and
other agreements with end-product manufacturers such as
manufacturers of flat glass, flat panel displays and automotive
products, and with other interested companies who may wish to
acquire rights to manufacture and sell the Company's
proprietary emulsions and films.

     The Company's plans also call for further development of
its technology and the provision of additional technological and
marketing assistance to its licensees to develop commercially
viable SPD-Smart products, and expand the markets for such
products. The Company cannot predict when or if new license
agreements will be entered into or the extent to which
commercial products will result from its existing or future
licensees because of general economic conditions and the risks
inherent in the developmental process and because
commercialization is dependent upon the efforts of its licensees
as well as on the continuing research and development efforts
of the Company.


Competitive Technologies

     The Company believes that its SPD light-control
technology has certain performance advantages over other
"smart glass" technologies which electrically vary the amount
of light passing through windows and other smart products.
Since the non-SPD technologies listed below do not have
published consistent pricing or cost data that can be relied upon,
the Company does not describe any relative cost advantages
that SPD technology might have over these other technologies.

     Variable light transmission technologies can be classified
into two basic types: "active" technologies that can be
controlled electrically by the user either automatically or
manually, and "passive" technologies that can only react to
ambient environmental conditions such as changes in lighting
or temperature. One type of passive variable light transmission
technology is photochromic technology; such devices change
their level of transparency in reaction to external ultra-violet
radiation withut control by the user. As compared to photochromic
technology, the Company's SPD technology permits the user to
adjust the amount of light passing through the viewing area of
the device, rather than the viewing area of the photochromic
device merely reacting to external radiation. In addition, the
reaction time necessary to change from light to dark with
SPD-Smart technology can be almost instantaneous, as compared
to the much slower reaction time for photochromic devices. Also,
unlike SPD technology, photochromic technology does not
function well at the high and low ends of the temperature range
in which smart windows and other devices are normally
expected to operate, nor does photochromic technology perform
well in vehicles or other enclosed settings where existing glass
is blocking incoming ultra-violet light which is required for
photochromic devices to operate.

     Similarly, thermochromic smart windows are passive systems
which change their light transmission properties as sunlight
heats or cools the glass. Because the light transmission
properties of thermochromic systems are not controlled by the
user, their ability to adapt to the specific needs of occupants
is very limited. For example, thermochromic glazings will remain
tinted on hot days even when occupants desire more daylight to
enter the building or when they want to preserve their views.
SPD-Smart windows, which require very low amounts of power to
operate, allow for much greater control of incoming light, glare
and heat and can be adjusted to any level of light transmission
from dark to clear at any time. In addition, SPD-Smart windows
can block up to 99.5% of incoming light, a level many times
darker than thermochromic systems. The added advantage offers
much higher levels of privacy and control over incoming solar
energy. Companies involved in thermochromic technology include
Pleotint, Suntek and Ravenbrick.

     Active, user-controllable technologies, sometimes referred
to as "smart" technologies, are generally more useful than
passive technologies because they allow the user to actually
control the state of the window. This control is achieved with a
manual adjustment, or automatically when coupled with a timer
or sensing device such as a photocell, motion detector,
thermostat or other intelligent building system. There are three
main types of active devices which are compared below:

-  Electrochromic devices (EC)
-  Liquid crystal devices (LC)
-  Suspended-particle devices (SPD)

    Electrochromic Technology: Electrochromic windows and rear-
view mirrors use a direct current voltage to alter the molecular
structure of electrochromic materials (which can be in the form
of either a liquid, gel or solid film) causing the material to
darken. When compared to electrochromic devices, SPD
technology is expected to have numerous potential performance
and manufacturing advantages, including some or all of the
following:

-  faster response time, especially for larger glazings which
   can take many minutes to switch
-  ability to precisely "tune" intermediate light-transmission states
-  consistent switching speed regardless of size of glazing area
-  more reliable performance over a wider temperature range
-  higher contrast ratios and the capability of achieving
   darker shaded states for large area product applications
-  unpowered state is dark, maximizing solar heat gain benefits
   when the room, office or vehicle is not in use
-  lower electrical current drain
-  higher estimated battery life in applications where
   batteries are used
-  no "iris effect" (where light transmission changes first
   occur at the outer edges of a window or mirror and then
   work their way toward the center) when changing from
   clear to dark and back again
-  SPD technology is a film-based technology that can be
   applied to plastic as well as glass, and which can be
   applied to curved as well as flat surfaces
-  ability to be used with either glass or plastic substrates.

     Many companies with substantially greater resources than
Research Frontiers such as 3M, Gentex Corp., Pilkington, PPG
Industries, Saint-Gobain Glass and other large corporations
have pursued or are pursuing projects in the electrochromic
area. While some of these companies have reportedly
discontinued or substantially curtailed their work on
electrochromics due to technical problems and issues relating to
the expense of these technologies, at least four companies,
Saint-Gobain Glass, Sage Electrochromics, Inc., Gentex Corp.
and PPG Industries are currently actively working to
commercialize electrochromic window products.

     Liquid Crystal Technology: To date, the main types of liquid
crystal smart windows have been produced by Taliq Corp. (a
subsidiary of Raychem Corp. which has since discontinued its
liquid crystal operations and licensed its technology to others),
Asahi Glass Co., Nippon Sheet Glass, Saint-Gobain Glass,
Polytronix, Inc., DMDisplays, iGlass Projects Pty Limited, and
3M (which has also reportedly discontinued its liquid crystal
film making operations). The first three companies listed above
are also licensees of Research Frontiers Inc. for SPD-Smart
technology. Liquid crystal windows only change from a cloudy,
opaque milky-white to a clear state, are hazy when viewed at an
angle and have no useful intermediate states. As compared to
liquid crystal windows, SPD smart windows are expected to
have some or all of the following advantages:

-  have less haze
-  provide shading without loss of view
-  operate over a wider temperature range
-  use less power
-  have higher contrast ratios
-  absorb and shade light, rather than simply scatter it
-  permit an infinite number of intermediate states between a
   transparent state and a dark blue state, rather than being
   just two states.
-  offer superior solar heat gain control

   In the flat panel display market, further development (such
as the achievement of faster switching speeds sufficient for full-
motion video applications) is required if the Company expects
to compete against various display technologies that are
currently being used commercially such as liquid crystal
displays ("LCDs") and organic light-emitting diodes
("OLEDs"). Some of the advantages that SPD displays might
have include the ability to make displays without using sheet
polarizers or alignment layers, and lower light loss and a
corresponding reduction in backlighting requirements. Because
of further development work to be done in this area, the
Company cannot estimate when, or if, its licensees may begin
to penetrate the flat panel display market.

    LCDs and other types of displays, liquid crystal windows,
as well as electrochromic self-dimmable rear-view mirrors, are
already on the market, whereas products incorporating SPD
technology (as well as electrochromic windows) have only
begun to appear in the marketplace. Therefore, the long-term
durability and performance of SPD-Smart displays have not yet
been fully ascertained. The companies manufacturing LCD and
other display devices, liquid crystal windows, and
electrochromic self-dimmable rear-view mirrors and windows,
have substantially greater financial resources and
manufacturing experience than the Company. There is no
assurance that comparable systems having the same advantages
of the Company's SPD technology could not be developed by
competitors at a lower cost or that other products could not be
developed which would render the Company's products
difficult to market or technologically or otherwise obsolete.

Research and Development

     As a result of the Company's research and development
efforts, the Company believes that its SPD technology is now,
or with additional development will become, usable in a
number of commercial products. Such products may include
one or more of the following fields: "smart" windows, doors,
skylights and partitions, variable light transmission eyewear
such as sunglasses and goggles, self-dimmable automotive
sunroofs, sunvisors and mirrors, and instruments and other
information displays that use digits, letters, graphic
images, or other symbols to supply information, including
scientific instruments, aviation instruments, automobile
dashboard displays and, if certain improvements can be
made in various features of the Company's SPD technology
that increases switching speed to the levels needed for
video applications, portable computer displays and flat
panel television displays. Even though the Company's
SPD technology has much faster switching speeds than
electrochomic technology, current switching speeds are not
fast enough for such video applications. The Company
believes that most of its research and development efforts
have applicability to products that may incorporate the
Company's technology. At its current state of
development, the Company's technology has been judged
sufficiently advanced by various of its licensees and their
customers for them to proceed with the development,
introduction and sale of SPD-Smart products. However, the
Company is continuously investing in research and
development because it believes that further improvements will
result in accelerated and increased market penetration. The
Company intends to continue its research and development
efforts for the foreseeable future to improve its SPD light-
control technology and thereby assist our licensees in the
product development, sales and marketing of various existing
and new SPD-Smart products.

     During the past few years, and during the past year in
particular, the Company and/or its licensees have made
significant advances relating to materials to enable
(1) improved stability of SPD emulsions, (2) a wider range of
light transmission, and (3) improved film adhesion and
cohesion.

     The Company has devoted most of the resources it has
heretofore expended to research and development activities
with the goal of producing commercially viable SPD products
and has developed working prototypes of SPD-Smart products
for several different applications, with primary emphasis on
smart windows for various industries.In addition to working
with the Company's licensees, Research Frontiers has also
expanded its efforts to also work directly with some of our
licensees' major customers.

   Research Frontiers' main goals in its research and development are:

-   developing wider ranges of light transmission and quicker switching speeds
-   developing different colored particles
-   reducing the voltage required to operate SPDs
-   obtaining data and developing improved materials regarding
    environmental stability and longevity
-   quantifying the degree of energy savings expected by users
    of the Company's technology including the degree that SPD
    technology can control heat and its contribution to energy
    savings directly and through daylight harvesting strategies in
    sustainable building designs.

     Excluding non-cash expenses of approximately $26,000, $0,
and $1,236,000 associated with the grant of stock options to
the Company's technical personnel, Research Frontiers
incurred approximately $1,524,000, $1,470,000, and $1,293,000,
during the years ended December 31, 2009, 2008, and 2007,
respectively, for research and development. Research
Frontiers plans to engage in substantial continuing research and
development activities to invest in future improvements in SPD
light-control technology and to expand for its licensees the
capabilities of SPD-Smart technology and the markets for SPD-
Smart products.

Patents and Proprietary Information

     Research Frontiers continues to make substantial
investments in improving SPD-Smart light-control technology
and to expanding its intellectual property portfolio. The
Company has 31 United States patents in force, and four United
States patent applications are pending. The Company's United
States patents expire at various dates from 2010 through 2025.
The Company has approximately 232 issued foreign patents and
244 foreign and international patent applications pending. The
Company's foreign patents expire at various dates from 2010
through 2026. The Company believes that its SPD light-control
technology is adequately protected by its patent position and by
its proprietary technological know-how. However, the validity
of the Company's patents has never been contested in any
litigation. The Company also possesses know-how and relies on
trade secrets and nondisclosure agreements to protect its
technology. The Company generally requires any employee,
consultant, or licensee having access to its confidential
information to execute an agreement whereby such person
agrees to keep such information confidential.

    Research Frontiers' licensees have also directed the
Company not to reveal aspects of their activities or those of
their customers, which limits the Company's ability to disclose
certain information.

Rights Plan

    In February 2003, the Company's Board of Directors
adopted a Stockholders' Rights Plan and declared a dividend
distribution of one Right for each outstanding share of
Company common stock to stockholders of record at the close
of business on March 3, 2003. Subject to certain exceptions
listed in the Rights Plan, if a person or group has acquired
beneficial ownership of, or commences a tender or exchange
offer for, 15% or more of the Company's common stock, unless
redeemed by the Company's Board of Directors, each Right
entitles the holder (other than the acquiring person) to purchase
from the Company $120 worth of common stock for $60. If the
Company is merged into, or 50% or more of its assets or
earning power is sold to, the acquiring company, the Rights will
also enable the holder (other than the acquiring person) to
purchase $120 worth of common stock of the acquiring
company for $60. The Rights will expire at the close of business
on February 18, 2013, unless the Rights Plan is extended by the
Company's Board of Directors or unless the Rights are earlier
redeemed by the Company at a price of $.0001 per Right. The
Rights are not exercisable during the time when they are
redeemable by the Company. The above description highlights
some of the features of the Company's Rights Plan and is not a
complete description of the Rights Plan. A more detailed
description and a copy of the Rights Plan is available from the
Company upon request.

ITEM 1A.  	RISK FACTORS

     In addition to the other information in this Annual Report
on Form 10-K, you should carefully consider the following
factors in evaluating us and our business. This Annual Report
contains, in addition to historical information, forward-looking
statements that involve risks and uncertainties. Our actual
results could differ materially. Factors that could cause or
contribute to such differences include, but are not limited to,
those discussed below, as well as those discussed elsewhere in
this Annual Report, including the documents incorporated by
reference.

     There are risks associated with investing in companies
such as ours who are engaged in research and development. In
addition to risks which could apply to any company or business,
you should also consider the business we are in and the
following:

     Research Frontiers has a history of operating losses,
expects to incur additional losses in the future, and
consequently will need additional funds in the future to
continue its operations. Because we expect that our future
revenues will consist primarily of license fees (which have not
been significant to date), unless our licensees produce and sell
products using our technology, Research Frontiers will not be
profitable. There is no guarantee that we will ever be profitable.
Since Research Frontiers was started in 1965 through December
31, 2009, its total net loss was $76,399,353. Our net loss was
$4,002,761 in 2009, $2,594,843 in 2008 and $7,565,218 in 2007
(which includes non-cash accounting charge in 2009, 2008 and
2007 of $445,913, $126,408 and $4,026,855, respectively,
resulting from the expensing of stock options).

     We have funded our operations by selling our common
stock to investors. If we need additional money, there is no
guarantee that it will be available when we need it, or on
favorable terms. The Company would have to raise additional
capital no later than the first quarter of 2011 if operations,
including research and development and marketing, are to be
maintained at current levels if its revenues do not increase
before then. Eventual success of the Company and generation
of positive cash flow will be dependent upon the extent of
commercialization of products using the Company's technology
by the Company's licensees and payments of continuing
royalties on account thereof.

     Research Frontiers depends upon the activities of its
licensees in order to be profitable. We do not directly
manufacture or market products using SPD technology.
Although a variety of products have been sold by our licensees,
and because it is up to our licensees to decide when and if they
will introduce products using SPD technology, we cannot
predict when and if our licensees will generate substantial sales
of such products. Research Frontiers' SPD technology is
currently licensed to 37 companies. Other companies are also
evaluating SPD technology for use in various products. In the
past, some companies have evaluated our technology without
proceeding further. Also, we do not intend to manufacture
products using SPD technology. Instead we intend to continue
to license our SPD technology to manufacturers of end
products, films and emulsion. We expect that our licensees
would be primarily responsible for manufacturing and
marketing SPD-Smart products and components, but we are
also engaging in market development activities to support our
licensees and build the smart glass industry.

     Products using SPD technology have only recently begun
to be introduced into the marketplace. Developing products
using new technologies can be risky because problems,
expenses and delays frequently occur, and costs may or may
not come down quickly enough for such products using new
technologies to rapidly penetrate mass market applications.
Research Frontiers cannot control whether or not its
licensees will develop SPD products. Some of our licensees
appear to be more active than others, some appear to be
better capitalized than others, and some licensees appear
to be inactive. There is no guarantee when or if our
licensees will successfully produce any commercial product
using SPD technology in sufficient quantities to make
the Company profitable.

     Because SPD technology is the only technology Research
Frontiers works with, our success depends upon the viability of
SPD technology which has yet to be fully proven. We have not
fully ascertained the performance and long-term reliability of
our technology, and therefore there is no guarantee that our
technology will successfully be incorporated into all of the
products which we are targeting for use of SPD technology. We
expect that different product applications for SPD technology
will have different performance and reliability specifications.
We expect that our licensees will primarily be responsible for
reliability testing, but that we may also continue to do
reliability testing so that we can more effectively focus our
research and development efforts towards constantly improving
the performance characteristics and reliability of products using
SPD technology.

ITEM 7. 	MANAGEMENT'S DISCUSSION AND ANALYSIS OF
	        FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Critical Accounting Policies

     The following accounting policies are important to
understanding our financial condition and results of operations
and should be read as an integral part of the discussion and
analysis of the results of our operations and financial position.
For additional accounting policies, see note 2 to our
consolidated financial statements, "Summary of Significant
Accounting Policies."

     The Company has entered into a number of license
agreements covering potential products using the Company's
SPD technology. The Company receives fees and minimum
annual royalties under certain license agreements and records
fee income on a ratable basis each quarter. In instances when
sales of licensed products by its licensees exceed minimum
annual royalties, the Company recognizes fee income as the
amounts have been earned. Certain of the fees are accrued by,
or paid to, the Company in advance of the period in which they
are earned resulting in deferred revenue.

     The Company expenses costs relating to the development
or acquisition of patents due to the uncertainty of the
recoverability of these items.

     All of our research and development costs are charged to
operations as incurred. Our research and development expenses
consist of costs incurred for internal and external research and
development. These costs include direct and indirect overhead
expenses.

     The Company has historically used the Black-Scholes
option-pricing model to determine the estimated fair value of
each option grant. The Black-Scholes model includes
assumptions regarding dividend yields, expected volatility,
expected lives, and risk-free interest rates. These assumptions
reflect our best estimates, but these items involve uncertainties
based on market conditions generally outside of our control. As
a result, if other assumptions had been used in the current
period, stock-based compensation expense could have been
materially impacted. Furthermore, if management uses
different assumptions in future periods, stock-based
compensation expense could be materially impacted in future
years.

      On occasion, the Company may issue to consultants either
options or warrants to purchase shares of common stock of the
Company at specified share prices. These options or warrants
may vest based upon specific services being performed or
performance criteria being met. In accounting for equity
instruments that are issued to other than employees for
acquiring, or in conjunction with selling, goods or services,
the Company would be required to record consulting expenses
based upon the fair value of such options or warrants on the
earlier of the service period or the period that such options
or warrants vest as determined using a Black-Scholes option
pricing model.

      The preparation of financial statements in conformity with
accounting principles generally accepted in the United States of
America requires us to make estimates and assumptions that
affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the
financial statements, and reported amounts of revenues and
expenses during the reporting periods. Actual results could
differ from these estimates. An example of a critical estimate is
the full valuation allowance for deferred taxes that was
recorded based on the uncertainty that such tax benefits will be
realized in future periods.

Results of Operations

Year ended December 31, 2009 Compared to the Year ended December 31, 2008

     The Company's fee income from licensing activities for 2009
was $709,811, as compared to $1,679,919 for 2008. This difference
in fee income was primarily the result of the receipt, in 2008,
of a one-time payment from a former licensee in full settlement of
past due minimum annual royalties for several years, the expiration
of an agreement with Hitachi Chemical regarding payments made by
Hitachi Chemical to the Company for guaranteed access to future
improvements in the Company's technology, the timing and amount
of minimum annual royalties paid, and the date of receipt of such
payment on certain license agreements, by end product licensees.
Certain license fees, which are paid to the Company in advance
of the accounting period in which they are earned can result in
the recognition of deferred revenue for the current accounting
period, which will be recognized as fee income in future periods.
Also, licensees may offset some or all of their royalty payments
on sales of licensed products for a given period by applying
these advance payments towards such earned royalty payments.
Because the Company's license agreements typically provide for
the payment of royalties by a licensee on product sales within
45 days after the end of the quarter in which a sale of a
licensed product occurs (with some of the Company's more
recent license agreements providing for payments on a monthly
basis), and because of the time period which typically will
elapse between a customer order and the sale of the licensed
product and installation in a home, office building, automobile,
aircraft, boat or any other product, there could be a delay
between when economic activity between a licensee and its
customer occurs and when the Company gets paid its royalty
resulting from such activity.

     Operating expenses increased by $223,916 for 2009 to
$3,183,492 from $2,959,576 for 2008. This increase was principally
the result of increased non-cash charges to operating expenses
($293,000) resulting from grant of restricted shares and warrants
to directors, employees and consultants, as well as higher directors
fees and expenses ($134,000), higher professional fees ($53,000),
partially offset by lower investor relations/marketing costs
($64,000), consulting costs ($75,000), bad debts expense ($57,000)
as well as lower payroll and related costs ($55,000). Differences
in the amount of directors fees recorded as expense by the Company
may be the result of the timing of the payment of such fees.

     Research and development expenditures increased by $79,947
TO $1,549,707 for 2009 from $1,469,760 for 2008. This increase
was principally the result of higher payroll and non cash
stock option compensation charges ($57,000) as well as
higher materials costs ($53,000) partially offset by lower
insurance costs ($11,000), allocated office expenses ($10,000)
and equipment rental costs ($5,000).

     Investment income for 2009 was $20,627 as compared to
$154,574 for 2008. The difference was due to lower cash balances
available for investment as well as lower interest rates during
2009.

     As a consequence of the factors discussed above, the Company's
net loss was $4,002,761 ($0.25 per share) for 2009 as compared to
$2,594,843 ($0.17 per share) for 2008.


Year ended December 31, 2008 Compared to the Year ended December 31, 2007

    The Company's fee income from licensing activities for
2008 was $1,679,919, as compared to $402,359 for 2007. This
difference in fee income was primarily the result of  the receipt
of a one-time payment from a former licensee in full settlement
of past due minimum annual royalties for several years and the
Company entering into a new agreement with Hitachi Chemical
regarding payments made by Hitachi Chemical to the Company
for guaranteed access to future improvements in the Company's
technology, the timing and amount of minimum annual
royalties paid, and the date of receipt of such payment on
certain license agreements, by end-product licensees. Certain
license fees, which are paid to the Company in advance of the
accounting period in which they are earned can result in the
recognition of deferred revenue for the current accounting
period, which will be recognized as fee income in future
periods. Also, licensees may offset some or all of their royalty
payments on sales of licensed products for a given period by
applying these advance payments towards such earned royalty
payments. Because the Company's license agreements typically
provide for the payment of royalties by a licensee on product
sales within 45 days after the end of the quarter in which a sale
of a licensed product occurs (with some of the Company's more
recent license agreements providing for payments on a monthly
basis), and because of the time period which typically will
elapse between a customer order and the sale of the licensed
product and installation in a home, office building, automobile,
aircraft, boat, or any other product, there could be a delay
between when economic activity between a licensee and its
customer occurs and when the Company gets paid its royalty
resulting from such activity.

     Operating expenses decreased by $2,814,451 for 2008 to
$2,959,576 from $5,774,027 for 2007.  This decrease was
principally the result of non-cash charges of $2,790,656 in 2007
relating to primarily fully vested stock options granted by the
Company.  Additional factors causing this decrease were lower
payroll costs ($41,000), marketing costs ($81,000), and patent
costs ($13,000) partially offset by increased reserves for
uncollectable accounts ($40,000) and higher insurance costs
($29,000).

     Research and development expenditures decreased by
$1,059,816 to $1,469,760 for 2008 from $2,529,576 for 2007.
This decrease was principally the result of non-cash charges of
$1,236,199 in 2007 relating to fully vested stock options
granted by the Company.  Offsetting this decrease were higher
payroll costs ($132,000), and insurance costs ($29,000).

     Investment income for 2008 was $154,574 as compared to
$336,026 for 2007.  The difference was primarily due to lower
cash balances available to invest, as well as lower interest rates
during 2008.

     As a consequence of the factors discussed above, the
Company's net loss was $2,594,843 ($0.17 per share) for 2008
as compared to $7,565,218 ($0.50 per share) for 2007.  The
difference is primarily due to non-cash accounting charges of
$4,026,855 ($0.26 per share) in 2007 relating to the issuance of
common stock options as well as $1,277,560 ($0.08 per share)
in higher fee income in 2008.


Financial Condition, Liquidity and Capital Resources

      During 2009, the Company's cash and cash equivalents
balance increased by $1,393,022 principally as a result of
cash proceeds from the sale of US Treasury Securities of
$2,299,496 as well as proceeds from the sale of common stock
of $2,850,000 partially offset by cash used for operations
of $3,732,527. At December 31, 2009, the Company had working
capital of $3,998,962 and total shareholders' equity of
$4,165,337.  On March 3, 2010, the Company received net
proceeds of $1,618,653 from the sale of 588,602 shares
to a group of accredited investors.  In addition to the
shares, the investors received 117,719 five-year warrants
to purchase Company Common Stock at a price of $5.00 per
share.  The securities were sold pursuant to the Company's
effective shelf-registration statement filed with the SEC.
The proceeds of this offering will be used by the Company
to expand its operations, including increasing marketing
programs for products using its state-of-the-art SPD
light-control film technology.

      During 2008, the Company's cash and cash equivalents
balance decreased $4,892,680 principally as a result of cash
used to fund operations of $2,414,276 as well as net purchases
of US Treasury Securities ($2,299,496), fixed assets ($76,220)
and $112,500 invested in SPD Control Systems.

      During 2007, the Company's cash and cash equivalent
balance increased by $4,259,671 principally as a result of net
proceeds received from the issuance of common stock and on
the exercise of options and warrants of $7,876,550 partially
offset by cash used to fund operations of $3,517,185.

       The Company occupies premises under an operating lease
agreement which expires on January 31, 2014 and requires
minimum annual rent which rises over the term of the lease to
approximately $176,669, plus tenant's share of applicable taxes.
These lease obligations are summarized over time as of
December 31, 2009:

					Payments due by period
	                      <1 year 1-3 years	 4-5 years >5 years   Total
Operating lease obligations  $169,000  $513,000	 $16,000   $    --  $698,000


     The Company expects to use its cash to fund its research
and development of SPD light valves, its expanded marketing
activities, and for other working capital purposes. The
Company's working capital and capital requirements depend
upon numerous factors, including the results of research and
development activities, competitive and technological
developments, the timing and cost of patent filings,
the development of new licensees and changes in the
Company's relationships with its existing licensees. The degree
of dependence of the Company's working capital requirements
on each of the foregoing factors cannot be quantified; increased
research and development activities and related costs would
increase such requirements; the addition of new licensees may
provide additional working capital or working capital
requirements, and changes in relationships with existing
licensees would have a favorable or negative impact depending
upon the nature of such changes. Based upon existing levels of
cash expenditures, existing cash reserves and budgeted
revenues, and the proceeds raised from the sale of stock
and warrants on March 3, 2010, the Company believes that it
would not require additional funding until the third quarter
of 2011. There can be no assurance that expenditures will
not exceed the anticipated amounts or that additional
financing, if required, will be available when needed or,
if available, that its terms will be favorable or acceptable
to the Company. Eventual success of the Company and
generation of positive cash flow will be dependent upon
the extent of commercialization of products using the
Company's technology by the Company's licensees
and payments of continuing royalties on account thereof.

Inflation

     The Company does not believe that inflation has a
significant impact on its business.

Related Party Transactions

  		None.

Forward Looking Statements

     The information set forth in this Report and in all publicly
disseminated information about the Company, including the
narrative contained in "Management's Discussion and Analysis
of Financial Condition and Results of Operations" above,
includes "forward-looking statements" within the meaning of
Section 21E of the Securities Exchange Act of 1934, as
amended, and is subject to the safe harbor created by that
section. Readers are cautioned not to place undue reliance on
these forward-looking statements as they speak only as of the
date hereof and are not guaranteed.

ITEM 7A.  	QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     At times, the Company invests available cash and cash
equivalents in money market funds or in short-term U.S.
treasury securities with maturities that are generally one year or
less. Although the rate of interest paid on such investments in
money market funds may fluctuate over time, each of the
Company's investments in U.S. treasury securities is made at a
fixed interest rate over the duration of the investment.
Accordingly, the Company does not believe it is materially
exposed to changes in interest rates as it generally holds these
treasury securities until maturity.

     The Company does not currently have any sales, purchases,
assets or liabilities determined in currencies other than the
U.S. dollar, and as such, is not subject to foreign currency
exchange risk.

ITEM 9A.	CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

      As of the end of the period covered by this Annual Report
on Form 10-K, the Company carried out an evaluation, under the
supervision and with the participation of the Company's
management, including the Company's Chairman and its Chief
Executive and Financial Officer, of the effectiveness of
the design and operation of the Company's disclosure controls
and procedures pursuant to Exchange Act Rule 13a-15(e) and
15d-15(e). Based upon that evaluation, the Company's Chairman
and its Chief Executive and Financial Officer concluded that
the Company's disclosure controls and procedures are effective
in timely alerting them to material information relating to
the Company (including its consolidated subsidiary) required
to be included in the Company's periodic SEC filings. Our
officers have concluded that as of December 31, 2009 our
disclosure controls and procedures are designed, and are
effective, to ensure that information required to be
disclosed by our company in the reports we file or submit
under the Exchange Act is recorded, processed, summarized
and reported, within the time periods specified in the
commission's rules and forms, and are also effective to
ensure that information required to be disclosed in the
reports that we file or submit under the Exchange Act is
accumulated and communicated to our management, including
our chief executive officer and chief financial officer,
to allow timely decisions regarding required disclosure.
There were no changes in the Company's internal control
over financial reporting during the quarterly period
ended December 31, 2009 that has materially affected,
or is reasonably likely to materially affect, the
Company's internal control over financial reporting.



Management's Report on Internal Control over Financial Reporting

     Our management is responsible for establishing and
maintaining adequate internal control over financial reporting,
as such term is defined in Exchange Act Rule 13a-15(f). Our
internal control system is designed to provide reasonable
assurance to our management and Board of Directors regarding
the preparation and fair presentation of published financial
statements. Under the supervision and with the participation of
our management, including our chief executive officer and chief
financial officer, we conducted an evaluation of the
effectiveness of our internal control over financial reporting
based on the framework in Internal Control-Integrated
Framework, issued by the Committee of Sponsoring
Organizations of the Treadway Commission, or the COSO
Framework. Based on our evaluation under the COSO
Framework, our management concluded that our internal control
over financial reporting was effective as of December 31, 2009.

     The effectiveness of our internal control over financial
reporting as of December 31, 2009 has been independently
audited by BDO Seidman, LLP, an independent registered
public accounting firm, as stated in their report that
is included herein.

Report of Independent Registered Public Accounting Firm

The Shareholders and Board of Directors
Research Frontiers Incorporated
Woodbury, New York

     We have audited Research Frontiers Incorporated's internal
control over financial reporting as of December 31, 2009, based
on criteria established in Internal Control-Integrated Framework
issued by the Committee of Sponsoring Organizations of the
Treadway Commission (the COSO criteria). Research Frontiers
Incorporated's management is responsible for maintaining
effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Item 9A,
"Management's Report on Internal Control Over Financial
Reporting." Our responsibility is to express an opinion on the
Company's internal control over financial reporting based on
our audit.

     We conducted our audit in accordance with the standards of
the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding
of internal control over financial reporting, assessing the risk
that a material weakness exists, and testing and evaluating the
design and operating effectiveness of internal control based on
the assessed risk. Our audit also included performing such other
procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our
opinion.

     A company's internal control over financial reporting is a
process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with generally
accepted accounting principles. A company's internal control
over financial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance
with authorizations of management and directors of the
company; and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized acquisition, use,
or disposition of the company's assets that could have a material
effect on the financial statements.

     Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

     In our opinion, Research Frontiers Incorporated
maintained, in all material respects, effective internal control
over financial reporting as of December 31, 2009, based on the
COSO criteria.

     We also have audited, in accordance with the standards of
the Public Company Accounting Oversight Board (United
States), the consolidated balance sheets of Research Frontiers
Incorporated as of December 31, 2009 and 2008, and the related
consolidated statements of operations, stockholders' equity, and
cash flows for each of the three years in the period ended
December 31, 2009 and our report dated March 10, 2010
expressed an unqualified opinion thereon.

ITEM 10.  DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE

     The Company has adopted a code of ethics applicable to its
Chief Executive Officer, Chief Operating Officer, Treasurer and
Chief Financial Officer, any Vice President and other employees
of the Company with important roles in the financial reporting
process. This Code of Ethics was adopted by the entire Board of

       		Report of Independent Registered Public Accounting Firm


The Shareholders and Board of Directors
Research Frontiers Incorporated
Woodbury, New York

   	We have audited the accompanying consolidated balance sheets
of Research Frontiers Incorporated as of December 31, 2009 and
2008 and the related consolidated statements of operations,
shareholders' equity and cash flows for each of the three years in
the period ended December 31, 2009. In connection with our
audits of the consolidated financial statements, we have also
audited the schedule as listed in the accompanying index.  These
consolidated financial statements and schedule are the
responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial
statements and schedule based on our audits.

   We conducted our audits in accordance with the standards of the
Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial
statements and schedule are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements and
schedule, assessing the accounting principles used and
significant estimates made by management, as well as
evaluating the overall presentation of the financial statements
and schedule.  We believe that our audits provide a reasonable
basis for our opinion.

   In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the financial
position of Research Frontiers Incorporated at December 31,
2009 and 2008, and the results of its operations and its cash
flows for each of the three years in the period ended December
31, 2009, in conformity with accounting principles generally
accepted in the United States of America.

    Also, in our opinion, the financial statement schedule when
considered in relation to the basic consolidated financial
statements taken as a whole, present fairly, in all material
respects, the information set forth therein.

    We also have audited, in accordance with the standards of the
Public Company Accounting Oversight Board (United States),
Research Frontiers Incorporated's internal control over financial
reporting as of December 31, 2009, based on criteria established
in Internal Control - Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway
Commission (COSO) and our report dated March 10, 2010
expressed an unqualified opinion thereon.

	(1)Business

Research Frontiers Incorporated ("Research Frontiers" or the
"Company") operates in a single business segment which is
engaged in the development and marketing of technology and
devices to control the flow of light. Such devices, often referred to
as "light valves" or suspended particle devices (SPDs), use
colloidal particles that are either incorporated within a liquid
suspension or a film, which is usually enclosed between two
sheets of glass or plastic having transparent, electrically
conductive coatings on the facing surfaces thereof. At least one of
the two sheets is transparent.  SPD technology, made possible by a
flexible light-control film invented by Research Frontiers, allows
the user to instantly and precisely control the shading of
glass/plastic manually or automatically. SPD technology has
numerous product applications, including: SPD-Smart(tm) windows,
sunshades, skylights and interior partitions for homes and
buildings; automotive windows, sunroofs, sun-visors, sunshades,
rear-view mirrors, instrument panels and navigation systems;
aircraft windows; eyewear products; and flat panel displays for
electronic products.  SPD-Smart light control film is now being
developed for, or used in, architectural, automotive, marine,
aerospace and appliance applications.

The Company has historically utilized its cash and the proceeds
from its investments to fund its research and development of SPD
light valves, for marketing initiatives, and for other working
capital purposes. The Company's working capital and capital
requirements depend upon numerous factors, including the results
of research and development activities, competitive and technological
developments, the timing and cost of patent filings, and the
development of new licensees and changes in the Company's
relationships with its existing licensees. The degree of dependence
of the Company's working capital requirements on each of the
foregoing factors cannot be quantified; increased research and
development activities and related costs would increase such
requirements; the addition of new licensees may provide additional
working capital or working capital requirements, and changes in
relationships with existing licensees would have a favorable or negative
impact depending upon the nature of such changes. There can be no
assurance that expenditures will not exceed the anticipated
amounts or that additional financing, if required, will be available
when needed or, if available, that its terms will be favorable or
acceptable to the Company. Eventual success of the Company and
generation of positive cash flow will be dependent upon the
commercialization of products using the Company's technology
by the Company's licensees and payments of continuing royalties
on account thereof.  To date, the Company has not generated
sufficient revenue from its licensees to fund its operations.

(2)         Summary of Significant Accounting Policies

(a)	Cash and Cash Equivalents

The Company considers securities purchased with original
maturities of three months or less to be cash equivalents. Cash
equivalents consist of short-term investments in money market
accounts at December 31, 2009 and 2008.

The Company maintains balances at financial institutions which
may exceed Federal Deposit Insurance Corporation ("FDIC")
insured limits.  The Company has not experienced any losses in
such accounts and believes it is not exposed to any significant
risks on its cash in bank accounts

(b)	Investments

The Company classifies investments in marketable securities as
trading, available-for-sale or held-to-maturity at the time of
purchase and periodically re-evaluates such classifications.
Trading securities are carried at fair value, with unrealized
holding gains and losses included in earnings.  Held-to-maturity
securities are recorded at cost and are adjusted for the
amortization or accretion of premiums or discounts over the life of
the related security.  Unrealized holding gains and losses on
available-for-sale securities are excluded from earnings and are
reported as a separate component of accumulated other
comprehensive income (loss) until realized.  In determining
realized gains and losses, the cost of securities sold is based on the
specific identification method.  Interest and dividends on the
investments are accrued at the balance sheet date.  At December
31, 2008, Investments consisted of $2.3 million in short term US
Treasury Securities which are stated at cost, which approximates
market value.These investments were sold during 2009.

(c)	Royalties Receivable

Royalties receivable are recorded at the amounts specified within
the license agreements when the collectability of the receivable is
reasonably assured. The receivables do not bear interest. The
allowance for doubtful accounts is the Company's best estimate of
the amount of probable credit losses in the Company's existing
royalties receivable. The Company determines the allowance
based on historical write off experience. The Company reviews its
allowance for doubtful accounts periodically. Past due accounts
are reviewed individually for collectability. Account balances are
charged off against the allowance after all means of collection
have been exhausted and the potential for recovery is considered
remote.

(d)	Fixed Assets

Fixed assets are carried at cost. Depreciation and amortization are
computed using the straight-line method over the estimated useful
lives of the assets.

(e)	Revenue Recognition/Fee Income

The Company has entered into a number of license agreements
covering its light control technology. The Company receives
minimum annual royalties under certain license agreements and
records fee income on a ratable basis each quarter. In instances
when sales of licensed products by its licensees exceed minimum
annual royalties, the Company recognizes fee income as the
amounts have been earned. Certain of the fees are accrued by, or
paid to, the Company in advance of the period in which they are
earned resulting in deferred revenue. Such excess amounts are
recorded as deferred revenue and recognized into income in future
periods as earned.

Fee income represents amounts earned by the Company under
various license and other agreements (note 8) relating to
technology developed by the Company. During fiscal 2009, three
licensees accounted for 29%, 21% and 18%, respectively of fee
income recognized during the year. During fiscal 2008, one
licensee accounted for 60% (based upon a one-time payment), and
another licensee accounted for 29% of fee income recognized
during the year.  During fiscal 2007, one licensee of the Company
accounted for 61% of fee income recognized during the year.


(f)	Basic and Diluted Loss Per Common Share

Basic earnings (loss) per share excludes any dilution. It is based
upon the weighted average number of common shares outstanding
during the period. Dilutive earnings (loss) per share reflects the
potential dilution that would occur if securities or other contracts
to issue common stock were exercised or converted into common
stock. The Company's dilutive earnings (loss) per share equals
basic earnings (loss) per share for each of the years in the three-
year period ended December 31, 2009 because all common stock
equivalents (i.e., options and warrants) were antidilutive in those
periods. The number of options and warrants that were not
included because their effect is antidilutive was 2,511,341, 2,627,480,
and 2,992,630 for 2009, 2008, and 2007, respectively.

(g)	Research and Development Costs

Research and development costs are charged to expense as
incurred.

(h)	Patent Costs

The Company expenses costs relating to the development or
acquisition of patents due to the uncertainty of the recoverability
of these items.

(i)	Use of Estimates

The preparation of the Company's consolidated financial
statements requires management of the Company to make a
number of estimates and assumptions relating to the reported
amount of assets and liabilities and the disclosure of contingent
assets and liabilities at the date of the consolidated financial
statements and the reported amounts of revenues and expenses
during this period. Actual results could differ from those estimates.

(j)	Income Taxes

Income taxes are accounted for under the asset and liability
method. Deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and
liabilities and their respective tax bases and operating loss and tax
credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change
in tax rates is recognized in income in the period that includes the
enactment date.

We recognize tax benefits only for tax positions that are more
likely than not to be sustained upon examination by tax authorities.
The amount recognized is measured as the largest amount of benefit
that is greater than 50 percent likely to be realized upon ultimate
settlement. Unrecognized tax benefits are tax benefits claimed in
tax returns that do not meet these recognition and measurement
standards. We classify accrued interest and penalties related to
any unrecognized tax benefits in our income tax provision. At
December 31, 2009 and 2008, we do not have accrued interest
and penalties related to any unrecognized tax benefits.  We
do not believe we have any uncertain tax positions as of
December 31, 2009 and 2008.

The tax years subject to examination by major tax jurisdictions
include the years 2006 and forward by the U.S. Internal Revenue
Service and certain states. The Company is not currently being
audited by any tax jurisdiction.

(k)	Fair Value of Financial Instruments

The fair value of a financial instrument is the amount at which the
instrument could be exchanged in a current transaction between
willing parties. The carrying amounts of all financial instruments
classified as a current asset or current liability are deemed to
approximate fair value because of the short maturity of those
instruments.

(l)	Equity-Based Compensation

We recognize all stock-based compensation as an expense in
the financial statements and such costs are measured at the
fair value of the award.  In addition to reflecting compensation
expense for new share-based payment awards, expense is also
recognized to reflect the remaining vesting period of awards
that had been included in pro-forma disclosures in prior
periods.  No new options were granted during 2009 or 2008.
During 2007, the Company granted fully vested options to
purchase 624,537 shares of common stock as well as options
to purchase 30,000 shares of common stock that vest over
the next two years.  These grants resulted in an aggregate
non cash compensation charge of $63,206, $126,408 and
$4,026,855 during 2009, 2008 and 2007, respectively.
Tax benefits related to stock option exercises are
reflected as financing cash inflows instead of operating
cash inflows.

The exercise price for stock options granted are generally
set at the average for the high and low trading prices
of the Company's common stock on the trading date
immediately prior to the date of grant, and the
related number of shares granted are fixed at the
date of grant.

In order to determine the fair value of stock options
on the date of grant, the Company uses the Black-Scholes
option-pricing model. Inherent in this model are assumptions
related to expected stock-price volatility, option term,
risk-free interest rate and dividend yield.  While the
risk-free interest rate and dividend yield are less
subjective assumptions that are based on factual data
derived from public sources, the expected stock-price
volatility and option term assumptions require a greater
level of judgment.

During 2009, the Company granted 100,000, 199,700 and
250 shares of restricted common stock to its directors,
employees and a consultant, respectively.  All of the
shares granted to the directors and the consultant, as
well as 1,200 shares granted to employees vested
immediately upon grant.  The remaining 198,500 shares
vest ratably over the 36 months subsequent to the grant
date.  In connection with a termination of employment,
888 shares of this grant have been cancelled.  The
market value per share on the date of grant was $2.14.
In connection with these grants, the Company charged
$358,224 to operations during 2009.

The Company also granted 175,000 and 9,000 warrants
to consultants during 2009.  These warrants vest ratably
over 59 and 24 months, respectively.  The warrants are
valued at fair value at the time that the related
services are provided using the Black-Scholes method.
The Company charged $24,483 to operations for 2009
in connection with these warrants.

(m)	Impairment of Long-Lived Assets

The Company reviews long-lived assets to determine whether
an event or change in circumstances indicates the carrying
value of the asset may not be recoverable. The Company
bases its evaluation on such impairment indicators as
the nature of the assets, the future economic benefit
of the assets and any historical or future profitability
measurements, as well as other external market
conditions or factors that may be present. If such impairment
indicators are present or other factors exist that indicate that the
carrying amount of the asset may not be recoverable, the Company
determines whether an impairment has occurred through the use of
an undiscounted cash flows analysis at the lowest level for which
identifiable cash flows exist. If impairment has occurred, the
Company recognizes a loss for the difference between the carrying
amount and the fair value of the asset. Fair value is the amount at
which the asset could be bought or sold in a current transaction
between a willing buyer and seller other than in a forced or
liquidation sale and can be measured as the asset's quoted market
price in an active market or, where an active market for the asset
does not exist, the Company's best estimate of fair value based on
discounted cash flow analysis. Assets to be disposed of by sale are
measured at the lower of carrying amount or fair value less
estimated costs to sell.

(n)      Recent Accounting Pronouncements

New Accounting Standards

In April 2009, the FASB issued FASB Staff Position No. FAS 107-1
and APB 28-1, "Interim Disclosures about Fair Value of Financial
Instruments" (now ASC Subtopic 825-10-65), which requires
disclosures about fair value of financial instruments for
interim reporting periods of publicly traded companies as
well as in annual financial statements. This Staff Position
is effective for interim reporting periods ending after
June 15, 2009, and its requirements are reflected herein.

In May 2009, the FASB issued SFAS No. 165, "Subsequent Events"
(now ASC Subtopic 855-10). This standard establishes principles
and requirements for subsequent events, which are events or
transactions that occur after the balance sheet date but before
financial statements are issued or are available to be issued.
In particular, this standard sets forth (a) the period after
the balance sheet date during which management of a reporting
entity shall evaluate events or transactions that may occur
for potential recognition or disclosure in the financial
statements, (b) the circumstances under which an entity
shall recognize events or transactions occurring after
the balance sheet date in its financial statements, and
(c) the disclosures that an entity shall make about events
or transactions that occurred after the balance sheet date.
This standard is effective for interim or annual financial
periods ending after June 15, 2009 and is to be applied
prospectively. The adoption of this standard did not have
a material impact on our results of operations or our
financial position.

In June 2009, the FASB issued SFAS No. 168, "The FASB
Accounting Standards CodificationTM and the Hierarchy of
Generally Accepted Accounting Principles - a replacement
of FASB Statement No. 162" (now ASC Subtopic 105-10, also
issued as ASU No. 2009-01). This standard establishes
the ASC as the source of authoritative accounting
principles recognized by the FASB to be applied by
nongovernmental entities in the preparation of
financial statements in conformity with generally
accepted accounting principles. This standard is
effective for financial statements issued for interim
and annual periods ending after September 15, 2009.
The adoption of this standard did not have an impact
on our results of operations or our financial position.

In January 2010, the FASB issued ASU No. 2010-06,
"Fair Value Measurements and Disclosures (Topic 820)
-Improving Disclosures about Fair Value Measurements."
ASU 2010-06 requires new disclosures regarding transfers
in and out of the Level 1 and 2 and activity within
Level 3 fair value measurements and clarifies existing
disclosures of inputs and valuation techniques for
Level 2 and 3 fair value measurements. ASU 2010-06
also includes conforming amendments to employers'
disclosures about postretirement benefit plan assets.
The new disclosures and clarifications of existing
disclosures are effective for interim and annual
reporting periods beginning after December 15, 2009,
except for the disclosure of activity within Level 3
fair value measurements, which is effective for
fiscal years beginning after December 15, 2010,
and for interim periods within those years.


(o)  Fair Value Measurements

We value financial instruments using a three-tier fair
value hierarchy, which prioritizes the inputs used in
measuring fair value.  These tiers include: Level 1,
defined as observable inputs such as quoted prices in
active markets for identical assets or liabilities; Level 2,
defined as inputs other than quoted prices for similar assets or
liabilities in active markets that are either directly or indirectly
observable; and Level 3, defined as unobservable inputs in which
little or no market data exists, therefore requiring an entity to
develop its own assumptions.

Financial assets accounted for at fair value on a recurring basis at
December  31, 2009 include cash equivalents of approximately
$3.8 million.  These assets are carried at fair value based on
quoted market prices for identical securities (Level 1 inputs).

	(3)	Note Receivable from SPD Control Systems

On May 9, 2007, the Company began participating in the funding
of the ongoing development of automotive controllers by SPD
Control Systems Corp., a licensee of the Company.  This
development work is to produce the electronic controllers to
operate SPD-Smart automotive windows and glass roof systems for
one or more of the top five automotive makers in the world.  The
Company's funding of this project is reflected in the form of a
senior secured convertible promissory note (the "Note") of SPD
Control Systems Corp. held by Research Frontiers' wholly-owned
subsidiary, SPD Enterprises Inc.  The Note, which is scheduled to
mature on May 10, 2010, bears interest at 10% per annum, is
secured by all of the assets (including intellectual property) of SPD
Control Systems, and is convertible at the option of SPD
Enterprises into common stock of SPD Control Systems at an
initial conversion price of $0.50 per share.  This conversion price
is adjustable downward to result in the issuance of SPD Enterprises
of additional shares of SPD Control Systems common stock under
certain conditions.  The Note provides for funding of up to
$150,000 by SPD Enterprises based upon the achievement of
certain development milestones by SPD Control Systems.  As of
December 31, 2009 and 2008, the principal amount outstanding
under this Note was $150,000. Interest receivable under this
note was $31,500 and $13,844 at December 31, 2009 and 2008
and is included with other current assets (2009) and other
assets (2008) in the accompanying balance sheet.

	(4)	Fixed Assets

Fixed assets and their estimated useful lives, are as follows:

         	            2009      2008     Estimated useful life
Equipment and furniture $1,271,398 $1,265,911  5 years
Leasehold improvements	   433,282    414,822  Life of lease or estimated life
                                               of asset if shorter
         		 1,704,680  1,680,733
Less accumulated depre-
 cition and amortization 1,560,910  1,520,833
                        $  143,770 $  159,900

	(5)   Accrued Expenses and Other

	Accrued expenses consist of the following at December 31, 2009 and 2008:


	                                    2009              2008
Payroll, bonuses and related benefits	$150,882	  $188,538
Professional services	       	          51,383	    47,887
Deferred rent			          28,509	    29,697
Other                                        361 	    40,893
	                 		$231,135          $307,015

	(6)	Income Taxes

	   There was no income tax expense in 2009, 2008 and 2007 due to
losses incurred by the Company.

	   The tax effects of temporary differences that give rise to
significant portions of the deferred tax assets at December 31,
2009 and 2008 are presented below.

 				         2009   	 2008
Deferred tax assets:
 Depreciation	                 $     84,000    $     75,000
 Capital loss carryforward	      312,000	      312,000
 Allowance for bad debts               75,000 	       82,000
 Net operating loss carryforwards  21,518,000      20,625,000
 Stock option expense               1,449,000       1,449,000
 Research and other credits           969,000       1,004,000
 Other temporary differences           15,000          15,000
 Total gross deferred tax assets   24,422,000      23,562,000
Less valuation allowance	   24,422,000      23,562,000
	                         $         --    $         --

     In assessing the realizability of deferred tax assets, the Company
considers whether it is more likely than not that some portion or all
of the deferred tax assets will not be realized. The ultimate
realization of deferred tax assets is dependent upon future taxable
income during the period in which those temporary differences
become deductible. The Company considers the scheduled reversal
of deferred tax liabilities, projected future taxable income, and tax
planning strategies in making this assessment. Based upon its
historical operating losses, utilization of deferred tax assets cannot
currently be determined. Accordingly, the Company has recorded a
full valuation allowance against the deferred tax assets, as they
will not be realized until the Company achieves profitable
operations in the future.

      At December 31, 2009, the Company had a net operating loss
carryforward for federal income tax purposes of $54,000,000,
varying amounts of which will expire in each year from 2010
through 2029. Research and other credit carryforwards of
$969,000 are available to the Company to reduce income taxes
payable in future years principally through 2028. Net operating
loss carryforwards of $2,400,000 and research and other credit
carryforwards of $31,000 are scheduled to expire during fiscal
2010, if not utilized.

	(7)	  Shareholders' Equity

	(b)	Options and Warrants

	(i)	Options

     In 1992, the shareholders approved a stock option plan (1992 Stock
Option Plan) which provides for the granting of both incentive
stock options at the fair market value at the date of grant and
nonqualified stock options at or below the fair market value at the
date of grant to employees or non-employees who, in the
determination of the Board of Directors, have made or may make
significant contributions to the Company in the future. The
Company initially reserved 468,750 shares of its common stock for
issuance under this plan. In 1994 and 1996, the Company's
shareholders approved an additional 300,000 shares and 450,000
shares, respectively, for issuance under this plan. As of December
31, 2001, no options were available for issuance under this Plan
and this Plan expired during 2002.

     In 1998, the shareholders approved a stock option plan (1998 Stock
Option Plan) which provides for the granting of both incentive
stock options at the fair market value at the date of grant and
nonqualified stock options at or below the fair market value at the
date of grant to employees or non-employees who, in the
determination of the Board of Directors, have made or may make
significant contributions to the Company in the future. The
Company may also award stock appreciation rights or restricted
stock under this plan. The Company initially reserved 540,000
shares of its common stock for issuance under this plan. In 1999,
the Company's shareholders approved an additional 545,000 shares
for issuance under this Plan, and in each of 2000 and 2002, the
Company's shareholders approved an additional 600,000 shares for
issuance under this Plan. No options are available for issuance
under this Plan, as this Plan expired in December 2007.

     In 2008, the shareholders approved the Company's 2008 Equity
Incentive Plan which provides for the granting of both incentive
stock options at the fair market value at the date of grant and
nonqualified stock options at the fair market value at the date of
grant to employees or non-employees who, in the determination of
the Board of Directors, have made or may make significant
contributions to the Company in the future. The Company may
also award stock appreciation rights, restricted stock, or restricted
stock units under this plan. The Company initially reserved 750,000
shares of its common stock for issuance under this plan, and 450,938
options and other awards were available for issuance under this
plan as of December 31, 2009.

     At the discretion of the Board of Directors, options expire in ten
years or less from the date of grant and are generally fully
exercisable upon grant but in some cases may be subject to vesting
in the future. Full payment of the exercise price may be made in

Balance at December 31, 2009             500,161           $  6.00-9.00


     Warrants generally expire from five to ten years from the date of
issuance. At December 31, 2009, the number of warrants
exercisable was 329,661 at a weighted average exercise price of
$6.84 per share.

     (c)	Class A and Class B Warrants

      n connection with a financing in 1998, the Company issued
Ailouros Ltd. a Class A Warrant (which was exercised in full as of
February 2004), as well as a Class B Warrant which expired on
September 30, 2008. The Class B Warrant was exercisable into
65,500 shares at an exercise price of $8.25 per share which
represents 120% of average of the closing bid and ask price of the
Company's common stock on the date of the Class B Warrant's
issuance. During 2007, 12,750 of the Class B Warrants were
exercised.

     (d)	Restricted Stock Grant

During 2009, the Company granted 100,000, 199,700 and 250 shares
of restricted common stock to its directors, employees and a
consultant, respectively.  All of the shares granted to the
directors and the consultant, as well as 1,200 shares granted
to employees vested immediately upon grant.  The remaining
198,500 shares vest ratably over the 36 months subsequent to
the grant date.  In connection with a termination of employment,
 888 shares of this grant have been cancelled.  The market
value per share on the date of grant was $2.14.  In connection
with these grants, the Company charged $358,224 to operations
during 2009.  The remaining stock-based compensation expense
for restricted stock awards is approximately $282,000 at
December 31, 2009, and the related period over which it
is expected that such costs will be recognized is
approximately two years.

    (8)	License and Other Agreements

      The Company has entered into a number of license agreements
covering various products using the Company's SPD technology.
Licensees of Research Frontiers who incorporate SPD technology into
end products pay Research Frontiers an earned royalty of 5-15% of net
sales of licensed products under license agreements currently in effect,
and may also be required to pay Research Frontiers fees and minimum
annual royalties. To the extent that products have been sold resulting in
earned royalties under these license agreements in excess of these
minimum advance royalty payments, the Company has recorded
additional royalty income. Licensees who sell products or components
to other licensees of Research Frontiers do not pay a royalty on such
sale and Research Frontiers will collect such royalty from the licensee
incorporating such products or components into their own end-products.
Research Frontiers' license agreements typically allow the licensee to
terminate the license after some period of time, and give Research
Frontiers only limited rights to terminate before the license expires.
Most licenses are non-exclusive and generally last as long as our
patents remain in effect. To date, revenues from license agreements
have not been sufficient to fund the Company's costs of operation.

	(9)		Commitments

     The Company has an employment agreement with one of its officers
which provides for an annual base salary of $425,000, and with
another officer which provides for an annual base salary of
$300,000, through December 31, 2010.

     The Company has a defined contribution profit sharing (401K) plan
covering employees who have completed one year of service.
Contributions are made at the discretion of the Company.  The
Company did not make any contributions to this plan for 2009, 2008 or
2007.

      The Company occupies premises under an operating lease agreement
which expires on January 31, 2014.  At December 31, 2009, the
approximate minimum annual future rental commitment under this
lease for the next five years are as follows:


	2010:		$169,000
	2011:		$171,000
	2012:		$173,000
	2013:		$192,000
	2014:		$ 16,000

     Rent expense, including other occupancy related expenses, amounted to
approximately $197,000, $191,000, and $177,000 for 2009, 2008, and
2007, respectively.

      (10)   Rights Plan

      In February 2003, the Company's Board of Directors adopted a
Stockholders' Rights Plan and declared a dividend distribution of one
Right for each outstanding share of Company common stock to
stockholders of record at the close of business on March 3, 2003.
Subject to certain exceptions listed in the Rights Plan, if a person or
group has acquired beneficial ownership of, or commences a tender or
exchange offer for, 15% or more of the Company's common stock,
unless redeemed by the Company's Board of Directors, each Right
entitles the holder (other than the acquiring person) to purchase from
the Company $120 worth of common stock for $60. If the Company is
merged into, or 50% or more of its assets or earning power is sold to,
the acquiring company, the Rights will also enable the holder (other
than the acquiring person) to purchase $120 worth of common stock of
the acquiring company for $60. The Rights will expire at the close of
business on February 18, 2013, unless the Rights Plan is extended by
the Company's Board of Directors or unless the Rights are earlier
redeemed by the Company at a price of $.0001 per Right. The Rights
are not exercisable during the time when they are redeemable by the
Company.

------------------------------------------
  (1)  Since per share information is computed independently for each
quarter and the full year, based on the respective average number of
common shares outstanding, the sum of the quarterly per share
amounts does not necessarily equal the per share amounts for the
year.

  2)  Fee income in the third quarter of 2008 was primarily due to the
receipt of a one-time payment from a former licensee in full settlement
of past due minimum annual royalties for several years.

 (3)  The Company incurred higher costs in the first quarter of 2009
relating primarily to approximately $284,000 of non-cash stock
compensation costs and $140,000 in directors fees.
