A few weeks after filing a lawsuit, Samsung has filed a complaint with the International Trade Commission, asking it to block the sales of graphics processors made by Nvidia in the US market. The complaint also names other companies including Biostar Microtech International, Elitegroup Computer Systems, and more.
Samsung's move is the latest chapter in an ongoing legal battle between the two companies that began a couple of months ago when Nvidia filed an ITC complaint against the South Korean company as well as Qualcomm, accusing the two of infringing on several of its graphics processing unit patents.
The chipmaker sought to block shipments of several Galaxy devices including the Galaxy Note Edge, Galaxy Note 4, Galaxy S5, Galaxy Note 3, and Galaxy S4 mobile phones, as well as the Galaxy Tab S, Galaxy Note Pro, and Galaxy Tab 2. The company also filed a lawsuit in the Delaware District Court seeking damages for infringement.
The ITC opened an investigation into the complaint last month.
In response, earlier this month, Samsung filed a patent-infringement suit in federal court in Richmond, Virginia, accusing Nvidia and one of its customers of infringing as many as eight chip-related patents. Nvidia termed the lawsuit "a predictable tactic."
"We have not seen the complaint so can’t comment, but we look forward to pursuing our earlier filed ITC action against Samsung products,’’ an Nvidia spokesperson said in a statement.
