Blow to Nintendo: US Court Rejects Claims Against Palworld and Revokes Patent

Nintendo has had to take a tough legal blow: the United States Patent Office has rejected all 26 claims contained in the application filed in 2025 regarding the mechanics of capturing and using creatures in combat. The decision, fully reported by GamesFray, comes after a previous initial approval, now completely overturned.

The patent concerned a system that allows the player to summon characters and make them fight in their place, a well-known mechanic in the Pokémon franchise, but also present in numerous other titles belonging to different genres, especially RPGs. The breadth of the claims had raised doubts from the outset, as it could have involved productions that are very different in structure and gameplay.

The request submitted by Nintendo was part of the legal dispute against Palworld, a title developed by PocketPair. The game closely resembles the Pokémon series due to its artistic direction but stands out from the latter for its much more varied and articulated gameplay: an open-world structure, real-time combat, and a building and weapon system make it a title quite distinct from those developed by The Pokémon Company.

With the complete rejection of the claims, one of the main tools on which Nintendo relied to strengthen its legal position falls. The outcome confirms that the mechanics of summoning and combat with player-controlled entities remain a common paradigm in the industry, not attributable exclusively to a single publisher.

The decision of the US Patent Office also highlights another crucial aspect: the difficulty in protecting through patents game systems that are already widespread or easily traceable to generic concepts. This is a decision that should not be underestimated because it guarantees a less constrained environment for a vast number of developers who have so far feared potential repercussions from Nintendo.

It remains to be seen what the next steps will be for the Japanese company, which may seek new legal avenues or reformulate its requests with a narrower scope. Meanwhile, the line between intellectual property protection and creative freedom continues to blur, often conflicting with each other.
