Samsung, which filed its lawsuit on Monday, is seeking damages for deliberate infringement of several technical patents, including a few that govern the way semiconductors buffer and use data.
The Asian electronics company also accuses Nvidia of false advertising when it says its "Shield" tablet sports the world's fastest mobile processor, the Tegra. Samsung cites benchmarking studies performed by researchers at Primate Labs as proving that claim false.
"We'll review and respond to these new claims against us, and look forward to presenting our case on how Nvidia GPU patents are being used without a license," Nvidia said in a statement on Tuesday.
Nvidia also pointed to a benchmarking study that supported its claim that the Tegra was the fastest mobile processor on the market.
