South Korea's Samsung Electronics Co Ltd has filed a complaint with the US International Trade Commission seeking to block computer-graphics chips made by Nvidia Corp from the US 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 US federal court on November 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.
