Subsidiaries of Xperi Corporation, a company that licenses intellectual property, have filed suit against Nvidia in the U.S. District Court of Delaware for patent infringement. The case hinges on Nvidia’s alleged violation of five of the company’s patents for technology used in its gaming and supercomputer GPUs.
During the company’s Q1 2019 earnings call, Xperi announced that its subsidiaries Invensas Corporation and Tessera Advanced Technologies had filed the suit:
In addition, today we filed a lawsuit against NVIDIA for patent infringement. We believe that NVIDIA is using our patent semiconductor technology in certain of its CPUs and processors and we have been speaking with NVIDIA for several years about taking a patent license. We ultimately could not reach an agreement and we felt that we needed to take this action to defend our intellectual property rights. We filed the case in Delaware Federal Court asserting 5 patents. — CEO Jon Kirchner, via Seeking Alpha.
