A Pennsylvania company has filed suit against Nintendo and Sony for allegedly violating its patent held for a "hand held computer input apparatus and method." The Wiimote, Nunchuk, Sixaxis, and PS3 Blu-ray remote were all named in the lawsuit filed last month in the US District Court for the Western District of Pennsylvania. Copper Innovations Group claims that these devices infringe on its 1996 patent for a method of sorting devices connected to a system by number identification.

Copper is after a cut of Wii's lucrative profits and PS3's (once there are some), seeking payment for damages, with interest, and legal fees. Copper is also calling for a permanent injunction that would prohibit Nintendo, Sony and 3rd-party manufacturers from further infringing on the patent.
