Nintendo and Sony face a patent infringement lawsuit filed by Copper Innovations Group in the United States District Court for the Western District of Pennsylvania. The Pennsylvania based company filed a patent in 1996 for a "Hand Held Computer Input Apparatus and Method." The method described therein provides for hardware identification numbers to be assigned to specified device transmissions that would then be used as a means to organize the input of these transmissions when connecting them to a system. The suit targets the Remote and Nunchuk from Nintendo’s wildly popular Wii gaming system in addition to Sony’s Sixaxis controller and Blu-ray remote.
