Nvidia said on Thursday that Qualcomm and Samsung had used Nvidia's patented technologies without a licence in Samsung's 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.
               
Nvidia Corp has sued rival chipmakers Qualcomm and Samsung Electronics, accusing both companies of infringing its patents on graphics processing technology.
               
The U.S. chipmaker vies with Qualcomm in the business of providing chips for smartphones and tablets. It said on Thursday that Qualcomm and Samsung had used Nvidia's patented technologies without a license in Samsung's mobile devices, including the just-launched Galaxy Note 4 and Galaxy Note Edge.
               
Nvidia said Samsung devices made with graphics technology from Qualcomm, Britain's ARM Holdings and Imagination Technologies infringed on its patents.
               
"They're using our technology for free in their devices today and they're shipping an enormous number of devices," Nvidia Chief Executive Jen-Hsun Huang said on a conference call.
               
Nvidia did not say it is suing Imagination or ARM but it did say it is asking the U.S. International Trade Commission to prevent shipments of Samsung devices containing ARM's Mali or Imagination's PowerVR graphics architectures, as well as Qualcomm's graphics technology.
               
Graphics technology from Imagination is also used in Apple Inc's iPhones. Asked whether Nvidia plans to sue Apple since it uses Imagination's technology, Huang declined to comment.
               
"Today we're focused on Samsung and Qualcomm, and we continue to have productive conversations with a lot of other companies out there," he said.
