The Taiwan-based Chimei Innolux Corp is suing Sony Corp for infringing on patents used in PlayStation 3 video game consoles, televisions, computer notebooks and cameras, according to the Reuters newsagency.
Chimei filed the second lawsuit with the US Disctict Court in Delaware yesterday, saying Sony engaged in “widespread infringement” of three patents dating back to 1998.
Chimei said the infringement came after it had invested tens of millions of dollars in developing liquid crystal display (LCD) panels and related products.
The complaint was filed a month after Chimei filed a similar lawsuit against Sony in the U.S. District Court for the Western District of Arkansas.
Reuters reports that Chimei is seeking unspecified compensatory damages, which it wants tripled because of what it considers Sony’s “willful” misconduct, and other remedies.
Sony is the world’s second-largest camera maker and the third-largest flat screen TV maker. The company posted an operating profit of 67 billion yen ($785 million) for the second fiscal quarter of 2010.
Chimei Innolux was formed in a three-way merger in March and overtook AU Optronics as Taiwan’s No. 1 LCD maker. It reported a second-quarter net profit of T$9.54 billion (US$298 million) on August 9.
