Samsung, NVidia lock horns over patent infringement accusations

By  | 

Samsung has filed a counter-suit against NVidia’s September lawsuit, which accused the Korean smartphone maker of infringing patents on its graphics-processing unit (GPU).

Samsung’s suit, filed in a U.S.federal court on November 4, claims that NVidia Corp had infringed several of its semiconductor-related patents and that it has made false claims about its products.

The Asian electronics giant is seeking damages for infringement of several of its technical patents, including a few that checks the way semiconductors buffer and use data.

Samsung, in its lawsuit, has also accused of NVidia of false advertising its “Shield” tablet touting that the tablet sports the world’s fastest mobile processor, the Tegra, which is not true. As an evidence, the Electronics giant has cited benchmarking studies performed by researchers at Primate Labs as proving that claim false.Samsung claimed its own Exynos 5433 processor and Apple’s A8X are comparatively faster.

“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.

Responding on the latest development, NVidia, in a statement on Tuesday, said “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 it wasn’t ready yet to respond formally to Samsung’s lawsuit, but still pointed to a benchmarking study to support its claim that the Shield is a better performer than Samsung’s Galaxy Note 4.
