Samsung Electronics sued AU Optronics 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 LCD products, the South Korea-based maker said today. Samsung also filed lawsuits with federal courts in Delaware and California.

Samsung also sued AU Optronics' customers Sanyo Electric, Acer and BenQ. The suit follows one that Samsung filed against Apple in April, after the iPad maker alleged Galaxy mobile devices copied Apple's technologies and designs.

In the complaint to the trade commission, Samsung said it is seeking an order prohibiting the import and sale of the LCD products used in televisions and computer monitors.
