Samsung Sues AU Optronics, Acer, Sanyo Over Flat-Panel Patents

Samsung Electronics Co., the world’s largest flat-screen maker, sued AU Optronics Corp. and three of the Taiwanese company’s customers in the U.S., alleging they infringed some of its display patents.

Samsung filed a complaint with the U.S. International Trade Commission over the companies’ use of its technologies without payment in liquid-crystal-display products, the Suwon, South Korea-based maker said today. Samsung also filed lawsuits with federal courts in Delaware and California, it said in an e-mailed statement.
