Samsung has hit back at complaints from chip maker Nvidia by accusing Nvidia itself of infringing chip patents.
In September, Nvidia accused the Samsung of infringing patents in relation to Nvidia’s GPU technology, but now Samsung Electronics has filed a complaint with the a US District Court claiming that Nvidia has infringed six Samsung patents. The filed complaint also accuses Nvidia customer Velocity Micro of infringing eight patents.
The chip designs said to have been infringed include technology to reduce a machine’s boot up time.
Samsung has also been accused of false advertising for its claim that the Shield tablet houses the fastest mobile CPU in the world, the Tegra K1. Samsung claims that both Apple’s A8X processor and Samsung’s own Exynos 5433 processor are faster.
In a blog post, Nvidia said it expected this response from Samsung after filing the initial complaints in September.
Nvidia said: "We filed patent lawsuits two months ago against Samsung and Qualcomm alleging that they’ve used our patented GPU technology without proper compensation to us.
"When we filed those suits in the International Trade Commission and Delaware District Court, we fully expected that we would be sued in response. It’s a predictable tactic.
"So, we weren’t surprised when, earlier this week, Samsung filed a lawsuit against us – adding in for good measure Velocity Micro, a small customer of ours based in Virginia."
