Letigation has been shooting back and forth between NVIDIA and Samsung. The legal battle started in September when NVIDIA filed a complaint with the U.S. International Trade Commission (ITC) over alleged patent infringement by Qualcomm and Samsung. Samsung retaliated with a patent infringement suit of its own and now the South Korean electronics giant filed a complaint with the ITC demanding an import ban on NVIDIA GPUs.
The complaint doesn't seem to be publicly available, and Bloomberg couldn't get a copy. However, the ITC's website has a brief description of it. The description reads in part:
Letter to Lisa R. Barton, Secretary, USITC; requesting that the Commission conduct an investigation under section 337 of the Tariff Act of 1930, as amended, regarding Certain Graphics Processing Chips, Systems on a Chip. and Products Containing the Same.
In addition to Nvidia, the complaint names a number of graphics card vendors that use Nvidia's GPUs. Among them: Biostar, ECS, EVGA, and Zotac.
