Invensas Corporation and Tessera Advanced Technologies, Inc. (TATI), both subsidiaries of publicly traded Xperi Corporation, have together filed suit in the District of Delaware against NVIDIA (1:19-cv-00861), alleging infringement of five patents generally related to semiconductor fabrication and packaging. The new complaint targets the provision of a large number of semiconductor products, including 40nm Fermi GPUs, 28nm Kepler GPUs, 28nm Maxwell GPUs, 16nm Pascal GPUs, 28nm Tegra K1 systems-on-chips (SoCs) (which allegedly incorporate 28nm Kepler GPUs), 20nm Tegra X1 SoCs (which allegedly incorporate 20nm Maxwell GPUs), and Tesla GPUs. Xperi’s last forays into litigation were global efforts, with a worldwide set of disputes against Broadcom ending in 2017 and a worldwide set of disputes against Samsung ending this past December.
