Nintendo's patent application for touchscreen-specific monster-catching mechanics has been rejected by the Japan Patent Office (JPO).

This development occurs amid a dispute with the developer of Palworld, a game featuring similar mechanics available on multiple platforms.
Facts First
- The Japan Patent Office (JPO) rejected Nintendo's patent application for touchscreen-specific monster-catching mechanics.
- Nintendo amended the patent claims in February before the rejection was communicated on April 24, 2026.
- The patent describes mechanics for using a 'capture item' to catch characters and having them appear in the field to fight.
- The application is part of a dispute with Palworld developer Pocketpair regarding 'Pokémon-style monster capture and throwing mechanics'.
- Palworld is available on Mac, PC, PS4, PS5, Xbox One, and Xbox Series X/S.
What Happened
The Japan Patent Office (JPO) examiner rejected Nintendo's patent application for touchscreen-specific monster-catching mechanics. The rejection was communicated on April 24, 2026. Nintendo had amended the claims for the patent in February. The application, numbered 2026-019762, is a divisional of a previous patent focusing on monster-catching mechanics and describes a game program for an apparatus equipped with a touch panel. Its claim language includes mechanics for using a 'capture item for capturing a field character' and using those characters to appear in the field and fight.
Why this Matters to You
If you play games on mobile devices or consoles, this patent decision may affect the variety of games you can access. The rejection of a broad patent claim could allow other developers to create games with similar monster-catching mechanics without facing legal challenges from Nintendo. This could lead to more competition and innovation in the genre. For players of Palworld, a game available on many platforms including PC and consoles, the ongoing dispute between its developer and Nintendo over these mechanics may now face a different legal landscape.
What's Next
Nintendo may appeal the JPO's decision or pursue other legal avenues to protect its intellectual property. The dispute with Pocketpair regarding Palworld's mechanics is likely to continue, but the patent rejection could influence its trajectory. Other game developers observing this case might feel more confident in exploring similar game mechanics, which could lead to a wider range of games for players in the future.
