Electronics manufacturer Philips claims that the Wii U infringes several of the company's patents and is seeking to have the system banned from being sold in the United States. Philips claims that Nintendo copied technologies that replicate a "user's real-life actions in-game" and that it uses a patent related to "user interfaces designed to be navigated by a pointing device" (such as a Wii Remote).
"Philips has engaged in the field of applied electronics and has conducted research in areas relating to visual representation of spatial processes and to automatic processes," the lawsuit reads. "The present patents-in-suit stem from these fields of research and development and claims protection for an interactive system for which a user can remotely control devices in an intuitive manner. Such intuitive remote control mechanisms are used in present-day home video game consoles."
Philips acknowledges in its lawsuit that Nintendo used motion-controlled hardware since the beginning of the Wii's launch, but the company claims that it notified Nintendo of both patents back in November and December 2011.
The company is seeking a trial by jury, a ban on the sale of Wii U consoles and other infringing hardware, plus damages.
