Japan Patent Office: "Unreasonable Misunderstanding" — Nintendo's game patent rejected, sparking a copyright dispute (1/2 page)

Japan’s Patent Office rejected Nintendo and The Pokémon Company’s game-related patent application for lack of inventiveness.

The office cited a 2013 fan-made YouTube game video as prior art.

Nintendo argued the video was infringing content, but the examiner said copyright infringement is irrelevant to patentability.

The decision highlights how fan-created game examples can affect patent review and may have implications for the Palworld dispute.
