Power Integrations Reports Verdict in Patent Case Against Fairchild Semiconductor

Power Integrations (Nasdaq:POWI) today announced a verdict reached in the company’s 2008 patent-infringement lawsuit against Fairchild Semiconductor. After a three-week trial in the U.S. District Court for the District of Delaware, a jury found that Fairchild infringes two Power Integrations patents. The infringement findings cover approximately 75 Fairchild products, including the following products and those with substantially identical infringing circuitry:

AS1000 FAN6754 FSEZ1217 PO268MY SG6846
AS1003 FAN6791 FSEZ1307 PO368MY SG6846A
AS1207 FAN6793 FSEZ1317 SG5841J SG6846B
DAP024 FAN6861 FSEZ2007 SG5842J SG6846C
FAN100 FAN6862 FSEZ2016 SG5842JA SG6846G
FAN102 FAN6862L FSEZ2037 SG5851 SG68502
FAN103 FAN6862R LTA504SG SG5851A SG68502A
FAN104 FSBH0170 LTA504SJ SG6741 SG68502B
FAN301 FSBH0270 LTA703S SG6741A SG6859
FAN400A FSBH0370 LTA704S SG6742 SG6859A
FAN400C FSBH0F70 LTA705S SG6742HL SG6860
FAN6747 FSEZ1016A LTA809FA SG6742HR SGP100
FAN6751 FSEZ1116 LTA810FA SG6742ML SGP101
FAN6752 FSEZ1216 LTA811FA SG6742MR SGP400
FAN6753 FSEZ1216B PO168MY SG6842J

The jury also upheld the validity of the infringed patents, and further found that Fairchild has induced others to infringe Power Integrations’ patents. Power Integrations will seek an injunction preventing further infringement and is seeking financial damages, as well as enhanced damages for willful infringement, issues that are to be decided in a separate trial to be held at a later date.

Of the two counterclaim patents asserted in the case by Fairchild, one was found by the jury not to be infringed. The jury found the second Fairchild patent to be infringed by a limited number of Power Integrations products, but further found that Power Integrations did not induce infringement by any customers, including customers outside the United States, who are therefore unaffected by the verdict. Power Integrations is challenging the enforceability of the Fairchild patent, an issue still to be decided by the judge overseeing the case. Nevertheless, Power Integrations estimates that even if the verdict were ultimately upheld, the sales potentially impacted amount to only about 0.1% of the company’s revenues.

The latest verdict follows rulings in two earlier cases brought by Power Integrations against Fairchild and its System General subsidiary. In 2006, Fairchild was found to infringe four Power Integrations patents, including the same two patents found infringed today. The Court issued a permanent injunction against more than 100 infringing Fairchild products in that case, and later found the infringement to be willful, resulting in enhancement of the damage award, which currently stands at $12 million. The results of that case are currently under appeal.

Also in 2006, the International Trade Commission (ITC) found that System General, later acquired by Fairchild, infringed two Power Integrations patents and issued an exclusion order barring the infringing products from the U.S. market.

Commented Balu Balakrishnan, president and CEO of Power Integrations: “We are gratified that the legal system has once again helped us protect our innovations, and we hope this decision will put a stop to Fairchild’s repeated violations of our intellectual property.”
