Nvidia on Thursday filed patent infringement lawsuits in Delaware against Samsung and Qualcomm concerning graphics processor technologies which Nvidia claims those companies have used in their products without license.
The graphics chip maker also asked the U.S. International Trade Commission (ITC) "to block shipments of Samsung Galaxy mobile phones and tablets containing Qualcomm's Adreno, ARM's Mali, or Imagination's PowerVR graphics architectures."
First Apple suing Samsung and now Nvidia wants to sue Samsung and Qualcomm. If Qualcomm Adreno came from AMD Radeon years ago, maybe Nvidia will sue AMD next (because AMD is DMA spelled sideways).
