Philips claim this is a breach of their motion patent.
Filed in Delaware on May 14th, Eurogamer reports the lawsuit pertains to two patents. The first, patent 6,285,379, is a "virtual body control device," such as allowing an on-screen character to move in relation to a physical object's motion. The second, patent 8,537,231, is titled "User interface system based on pointing device," and directly relates to the Wii Remote's ability to target points of a screen, such as with the Wii's home menu.
Electronista said that Philips, side from requesting a sales injunction, the suit requests compensation for infringing both patents, a tripling of the damages, and pre- and post-judgement interest on its damages. Philips is also requesting a trial by jury.
The lawsuit was filed just a week after Nintendo released its 2013 year-end report that revealed that the Company reported losses of $457 million after sales of the Wii U and 3DS hardware slumped.
Only 2.72 million Wii U consoles were sold in the year, far below the company's initial 9 million estimate at the start of the fiscal year.
