 Both patents were continuation applications of a patent application originally filed in November 1995.Nintendo was not involved in the case, as the technology used in the Rumble Pak and GameCube controller (and, subsequently, the Wii Remote) is based on a different design, for which Nintendo holds the patents and based on a Japan patent application filed on October 9, 1995.While Microsoft settled out of court, purchasing a 10% share in Immersion, Sony continued to defend the case.
