As it was expected, Samsung Electronics has accused Nvidia of infringing several of its chip patents and for making false claims about its products, following a suit afiled by Nvidia gainst the Korean company (and Qualcomm) in September. Samsung filed a lawsuit in a U.S. federal court in Virginia on Nov. 4. The company is seeking damages for infringement of eight patents, including a few retlated to the way semiconductors buffer and use data.

Samsung alleges that Nvidia's statement that the SHIELD tablet, with its Tegra K1 processor, has "the world’s fastest mobile processor" is false and misleading. Samsung alleges that its Exynos 5433 processor is faster on a couple benchmarks. Samsung Electronics cites benchmarking studies performed by researchers at Primate Labs as proving that claim false.

Samsung also added in the lawsuit Velocity Micro, a small Nvidia customer based in Virginia. Velocity is alleged to have violated all eight patnets.

"We are pursuing necessary legal measures to defend our intellectual property rights and to ensure our continued growth in the IT industry," Samsung Electronics said in an emailed statement.

"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 posted on its official blog some benchmarks that show the extent to which the SHIELD tablet outperforms Samsung’s device.

Nvidia claims thatt Samsung is trying to keep its lawsuit in Virginia, which has a faster time to trial than most jurisdictions in the United States.

Samsung's lawsuit came after Nvidia accused the Asian company and rival Qualcomm of infringing patents on its graphics-processing unit. The U.S. chipmaker said in September that Qualcomm and Samsung had used Nvidia's patented technologies without a license in Samsung's mobile devices, including the newGalaxy Note 4 and Galaxy Note Edge.
