Today sees Nintendo of America prevailing in a patent infringement lawsuit. At the center of the case was the Wii remote, Wii Balance Board, and Wii Fit software. Impulse technology claimed that these three devices or software infringed upon their patent (U.S. Patent No 5,524,637) which was issued in 1996.
The whole court battle started when Impulse claimed that Nintendo and other third-party studios infringed upon their 1996 patent that covered an "interactive system for measuring physiological exertion". Today, US District Court Judge James Gwin ruled against one of Impulse's legal arguments.
They didn't actually get a full ruling from the court. Rather, the court ruled that Impulse's argument wasn't exactly valid, so this resulted in the case being dismissed. Impulse also tried suing Microsoft and Kinect developers, saying the Kinect infringed on seven of its patents that were issued from 2010 to 2011.
