Samsung Electronics Co Ltd said on Friday that it will take all measures necessary against Nvidia Corp after the U.S. Nvidia said on Thursday that Qualcomm and Samsung had used Nvidias patented technologies without a license in Samsungs mobile devices, including the just-launched Galaxy Note 4 and Galaxy Note Edge. Samsung did not specify what actions it plans to take against Nvidia, which also sued rival chipmaker Qualcomm Inc for patent infringement.
