Nvidia and Samsung have settled their patent infringement suits [anandtech.com]. A small number of patents will be cross-licensed:
Roughly a year and a half ago, NVIDIA opened up a patent infringement case against Samsung and Qualcomm [anandtech.com], claiming that the various GPUs used by the two firms violated various NVIDIA patents. In response, Samsung opened up their own counter-suit [anandtech.com], claiming that NVIIDA and its partners were violating Samsung patents. Since then, things have not progressed well for NVIDIA, with the US International Trade Commission (ITC) ruling that Samsung's GPUs don't infringe on NVIDIA's patents [anandtech.com], while also ruling that NVIDIA's GPUs did infringe on Samsung's patents [anandtech.com].
Now with the final ruling on Samsung's counter-suit originally scheduled for today, NVIDIA has announced that they have buried the hatchet with Samsung [nvidia.com], ending all litigation between the companies. In their announcement, NVIDIA notes that both companies have ended their suits with the US courts, US ITC, and the US Patent office, effective immediately.
