A federal appeals court confirmed that a patent lawsuit against Nintendo by Triton Tech is invalid.

The lawsuit was originally filed in 2010, with Triton Tech alleging that Nintendo’s Wii Remote infringed on one of Triton’s patents: U.S. Patent No. 5, 181, 181, which involved Wii MotionPlus.

Judge Richard A. Jones of the Seattle district court had previously dismissed the lawsuit, and the June 13 federal appeals upheld that ruling.

“We are very pleased with this result,” said Richard Medway, Nintendo of America’s deputy general counsel. “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.”
