According to GeekWire, a federal appeals court has sided with Nintendo in a patent infringement lawsuit. The lawsuit was surrounding Nintendo’s Mii character creation and communication tool.

The suit was filed by RecogniCorp in 2011, claiming that Nintendo’s Mii tool was infringing on a patent they owned. The alleged patent was used to produce and store police sketches using composite images of faces. Allegedly, the Mii tool, which lets people create virtual avatars of themselves using their own photos for the 3DS and Wii U, uses similar techniques as RecogniCorp’s police sketch tools.

In the federal appeals court found that RecogniCorp had not shown an “inventive concept that transforms the claimed subject matter from an abstract idea into a patent-eligible application,” according to court documents. That means RecogniCorp’s patent should never have been granted, so there would have been nothing for Nintendo to infringe upon.

“The decision marks another case in which Nintendo’s unique ideas overcame unjustified threats of patent infringement, Ajay Singh, Nintendo of America’s director of litigation and compliance, said in a statement. “Nintendo has a long history of developing innovative products and we will continue to vigorously defend all our products from meritless patent lawsuits.”
