Nvidia (NASDAQ:NVDA) alleges Qualcomm's (NASDAQ:QCOM) Snapdragon processors and Samsung's Exynos processors infringe "GPU patents covering technology including programmable shading, unified shaders and multithreaded parallel processing." Complaints have been filed at a Delaware district court and the ITC.
A number of Samsung phones/tablets relying on Qualcomm and/or Samsung processors are featured in the complaint, including the Galaxy S5, Note 4, Tab S, and Tab 2.
Qualcomm's processors feature proprietary Adreno GPU cores, while Samsung's rely on cores developed by ARM and Imagination. Nvidia's Tegra processor line competes against Qualcomm and (indirectly) Samsung's offerings.
Nvidia already has a multi-year patent licensing deal with Intel that nets the company $66M/quarter. Last year, Nvidia announced it's willing to license its Kepler GPU architecture to third parties. Interest has been limited thus far.
Given its giant patent portfolio, Qualcomm might be tempted to file a countersuit.
