South Korea's Samsung Electronics Co Ltd has filed a complaint with the U.S. International Trade Commission seeking to block computer-graphics chips made by Nvidia Corp from the U.S. market, Bloomberg reported. Samsung had accused Nvidia of infringing several of its chip-related patents and for making false claims about its products, counter-suing after Nvidia filed a suit against the company in September. The Korean company's lawsuit came after Nvidia accused it and rival Qualcomm Inc of infringing patents on its graphics-processing unit (GPU). Samsung, which had filed the lawsuit in a U.S. federal court on Nov. 4, is seeking damages for deliberate infringement of several technical patents, including a few that govern the way semiconductors buffer and use data. The Bloomberg report said that the ITC complaint also named computer-parts manufacturers Biostar Microtech International Corp and Elitegroup Computer Systems Co. (Reuters)
