Power Integrations Reports Verdict in Patent Case Against Fairchild Semiconductor

Power Integrations 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.

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."
