Japan's patent office rejected Nintendo's Pokémon-style capture patent, citing prior games, weakening its legal stance in the Palworld case.
Japan's Patent Office has rejected a key Nintendo patent tied to the Pokémon-style creature-capture mechanic in the Palworld lawsuit, citing prior art from games like Monster Hunter, ARK: Survival Evolved, and Pokémon GO.
The decision, based on evidence including earlier mods and games, argues the patent lacks originality and inventive step.
While not legally binding, the ruling carries significant weight and could weaken Nintendo’s legal position.
Nintendo has 60 days to respond, potentially amending claims or appealing, which may extend the case into 2026.
