Back in September 2014, NVIDIA filed patent infringements against both Samsung and Qualcomm - and then a couple of months later in December 2014, the US International Trade Commission (ITC) said it would be investigating the lawsuit between Samsung and NVIDIA.
Well, a United States ITC judge has ruled that NVIDIA has infringed on three of Samsung's patents, and while this isn't a final design from the judge, NVIDIA will be counting down the days until the full ITC reviews the case a few months from now. One of the main patents expires in 2016, so any ban on products using that patent would only last a few months.
NVIDIA has repleid saying that it is "disappointed" in the ITC's verdict, rejecting the claim that Samsung was pulling old, irrelevant patents out of the closet. Samsung hasn't yet commented, but it insists that its patents are vital to making SoC products.
