Item 7.01 Regulation FD Disclosure

Research Frontiers'licensee Hitachi Chemical Company, Ltd. issued a
press release on BusinessWire today (December 16, 2009) which
announced details about its new production facility and the expansion of
its production capacity for roll-coated, wide-width suspended particle
device (SPD) light-control film. Hitachi Chemical is now supplying
commercially usable film to end-product licensees of Research Frontiers
for the automotive, architectural, marine and aircraft markets. With
its newly completed coating line dedicated to production of SPD film,
Hitachi Chemical reports that it has expanded its production capacity
of SPD film to 400,000 square meters (4.3 million square feet) per year.

SPD-Smart(TM) products use patented SPD film technology developed by
Research Frontiers. With the touch of a button or turn of a dial, users
can instantly and precisely adjust the tint of windows, sunroofs, glass
roof systems, skylights and other products. Automated adjustment of
SPD-Smart products also is available using sensors or timing devices.
SPD films can be combined with other glazing materials, such as those
used in armored glass, to meet a wide range of end-product requirements
across many applications. Because they instantly and precisely control
incoming light and heat, SPD-Smart products offer energy saving benefits
because they can manage solar heat build-up and lower energy used for
artificial lighting.

In its press release, Hitachi Chemical highlighted the growing demand
for smart glass and several of the advantages offered by SPD film
technology when compared to other switchable materials such as liquid
crystals and electrochromics. Customers for Hitachi Chemical's SPD film
are end-product licensees of Research Frontiers around the world. 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%.

Hitachi Chemical reports in its press release 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
on the company'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 projecting SPD film sales
of 5 billion yen ($53.4 million) in 2012.
