AMD has accused MediaTek, LG, Sigma Designs and Vizio of infringing its graphics processing patents. MediaTek has responded by issuing a company filing through the Taiwan Stock Exchange in response.
MediaTek confirmed that the case has entered judicial processes in the US and added that the litigation has not had any material impact on the company’s operations.
AMD filed a legal complaint with the US International Trade Commission against the four companies accusing them of infringing three of its graphics processing patents. The allegedly infringing products are MediaTek’s Helio P10 SoC used by LG in certain smartphone models, and Sigma’s SX7 SoC adopted in Vizio’s advanced TVs.
