Nintendo Faces Criticism From Japan Patent Office in Latest Rejection
Nintendo has faced a rejection from Japan’s Patent Office for a divisional patent covering monster-capturing game mechanics, marking another setback in the company’s broader patent strategy. Unlike the patent central to Nintendo’s lawsuit against Palworld, this rejected divisional patent represents a separate filing within the same patent family, specifically targeting the monster-capturing system mechanics.
The Japan Patent Office rejected the divisional patent citing insufficient inventive step. The rejection included an unusually blunt response from the patent office, based partly on gameplay mechanics demonstrated in a YouTube video of a fan-made game. The back-and-forth between Nintendo and the patent office highlights the complexity of patenting game mechanics, particularly in competitive markets where similar gameplay systems are common. This development adds another chapter to Nintendo’s broader intellectual property disputes and raises questions about the enforceability and scope of patents covering foundational game design concepts.
