Nintendo is facing another lawsuit over the Nintendo Wii. This time it’s Copper Innovations claiming that they hold a patent over some part of the Nunchuck/Wiimote connector.
The patent–which was filed in January of 1996–covers a method for connecting devices to a system and sorting their inputs by means of hardware identification numbers tied to each transmission. According to the suit, Nintendo and Sony are violating the Copper Innovations Group’s patent by making and selling their systems and controllers. The Wii Remote, Wii Nunchuk, Sixaxis controller, and Blu-ray Remote Control are all named in the suit as infringing products.
