What happened
In September 2024, Nintendo and The Pokemon Company filed a patent infringement lawsuit against Pocketpair, the studio behind Palworld. The game had sold over 25 million copies in its first month, drawing immediate comparisons to Pokemon for its creature-catching mechanics and visual style.
The lawsuit targets specific patents related to game mechanics — not copyright on character designs. This distinction matters for every game developer shipping creature-collection or survival-crafting games.
Why patents, not copyright
Copyright protects specific creative expression: art assets, code, music, story. You cannot copyright a game mechanic. This is why Nintendo went the patent route.
Nintendo holds patents on mechanics like:
- Throwing an object to capture a creature in an open-world environment
- The interaction between a player character and captured creatures during traversal
- Specific UI patterns for creature management
These are broad enough to potentially affect games beyond Palworld. Any developer building creature-collection mechanics should be aware of the patent landscape.
What this means for indie developers
The good news
Most indie games will never be large enough to attract patent litigation. The legal costs alone make it impractical for a patent holder to pursue small studios.
The bad news
If your game gains traction — especially in a genre where a major publisher holds patents — you could face unexpected legal challenges. Unlike copyright (which requires proving you copied specific expression), patents can be infringed even if you developed your mechanics independently.
The practical takeaway
- Monitor what ships in your genre. Understand the competitive landscape before you invest years of development.
- Research existing patents in your game's mechanic space, especially if you're building in a genre dominated by a major publisher.
- Document your development process. Timestamps, design documents, and commit history can all help establish independent creation.
How this case could play out
The case is ongoing as of early 2026. Possible outcomes:
| Outcome | Impact on industry |
|---|---|
| Nintendo wins broadly | Chilling effect on creature-collection games |
| Narrow ruling | Only specific mechanic combinations affected |
| Settlement | Pocketpair licenses patents, precedent unclear |
| Pocketpair wins | Patents invalidated or narrowed, more freedom for devs |
The bigger picture
This lawsuit is part of a longer trend. Game mechanics patents have been controversial since Namco patented loading screen mini-games in 1995. The industry has generally operated on the assumption that mechanics are fair game — this case could test that assumption.
For indie developers, the lesson is straightforward: know what's happening in your space. Whether it's a direct clone of your game appearing on the App Store or a major publisher asserting patent rights over mechanics you've been using, visibility into the market is the first step toward making informed decisions.
