A federal appeals court has dismissed a patent infringement claim against Nintendo's Wii Remote controller filed by Triton Tech in 2010. The lawsuit was first filed by Triton Tech in 2010, but was dismissed by a Seattle district court judge because the patent "did not adequately describe a complete invention." The judge rendered the patent invalid. But Triton decided to appeal the decision in the federal appeals court. The Appeals court upheld the lower court ruling on June 13.
Triton's patent No. 5,181,181 was filed in 1990 for "a mouse which senses six degrees of motion arising from movement of the mouse within three dimensions."
In announcing another court victory against would-be patent infringement claims, Nintendo said that it was pleased with the results.
"We are very pleased with this result," Nintendo of America general counsel Richard Medway said in a prepared statement. "Nintendo has a long tradition of developing unique and innovative products, while respecting the intellectual property rights of others. Nintendo continues to aggressively defend itself against patent trolls. After many years of litigation, the decision today reflects an appropriate resolution of this case."
While Nintendo has been sued multiple times over patent infringement claims, it has almost always walked away unscathed. Its most recent court battle is with Philips, who sued Nintendo in May over its patent on a "virtual body control device", which allows users to control interfaces using "intuitive" motions. The company is seeking to block North American sales of Wii, Wii Remote, Wii U, Wii U GamePad, and Wii Mini - and of course to collect damages.
