Nintendo's detachable controller design draws accusations of patent infringement

A third-party hardware developer filed a lawsuit against Nintendo this week, alleging that the Nintendo Switch's detachable Joy-Con controllers infringe on its patents.

Gamevice filed a complaint for patent infringement against Nintendo with the U.S. District Court for the Central District of California on Wednesday, saying that the Nintendo Switch's design is too similar to that of its own devices, the Wikipad and the Gamevice controller. Gamevice is calling for Nintendo to stop Switch production and is asking for damages.
