SAN FRANCISCO—Fairchild Semiconductor International Inc said Tuesday (May 1) it filed new patent infringement claims in US federal court against Power Integrations Inc's LinkSwitch-PH LED power conversion products.
Fairchild (San Jose, CA) said it asserted three new patents that extend its primary side regulation technology against Fairchild in the suit, filed in US District Court in Delaware.
Last week, a jury in the same District Court found that Power Integrations products, including some LinkSwitch II and LinkSwitch-CV products, infringe on a Fairchild patent for primary side regulation technology. The same jury also found that several Fairchild products infringe upon two Power Integrations patents.
Fairchild said Tuesday it would seek an injunction preventing further infringement and is seeking financial damages. Willfulness and damages in that case will be determined in a second phase, which has yet to be scheduled and may occur after appeals of the first phase, Fairchild said.
