An anonymous reader quotes a report from Engadget: Nintendo is under investigation by the U.S. International Trade Commission, and the fate of the Switch hangs in the balance. Gamevice, the company behind the Wikipad and a line of snap-on controllers for mobile devices, says the Nintendo Switch violates its patents on attachable handheld gamepads and their related accessories. Alleging violations of the Tariff Act of 1930, Gamevice is requesting a cease and desist order against Nintendo, a move that would halt imports of the Switch into the U.S. The USITC notes that while its investigation has begun, it hasn't ruled on the validity of the complaint. The commission will hold an evidentiary hearing to determine whether Nintendo is in violation of the Tariff Act, with a final decision "at the earliest practicable time." The USITC will announce a target date for the end of the investigation within 45 days.
