It's true, Samsung is about to find itself back in the courtroom facing another round of patent litigation -- but this time, the lawsuit isn't coming from a direct competitor. NVIDIA just filed its first patent lawsuit in the company's 21 year history, and charging both Samsung and Qualcomm with infringing seven of its GPU patents. NVIDIA says that it's tried to negotiate licensing fees with the companies directly, but have made no progress. "Samsung repeatedly said that it was mostly their suppliers' problem," the company wrote on its official blog. Now NVIDIA is taking them both to court.
