Palworld officially launched in version 1.0 on July 10, 2026 — but the game's real story over the past two years has had less to do with catching creatures and more to do with a courtroom in Tokyo.
Since September 2024, Nintendo and The Pokémon Company have been suing developer Pocketpair over three patents covering creature-capture mechanics. Pocketpair's defense hasn't been to deny the similarities to Pokémon outright — it's been to argue that Nintendo doesn't actually own these mechanics in the first place. As evidence, Pocketpair's team pointed to prior examples of similar systems, including a Dark Souls 3 mod called "Pocket Souls" that let players capture enemies in a very comparable way, years before Palworld existed.
That argument gained real traction: in October 2025, Japan's patent office partially sided with Pocketpair, rejecting one of Nintendo's patent applications for lacking originality — citing prior art from games like ARK: Survival Evolved, Monster Hunter 4, and even Pokémon GO as evidence the mechanic wasn't novel to begin with.
While the case dragged on, Pocketpair kept shipping updates that quietly moved the game further from the disputed patent claims — removing a ball-throwing capture animation in November 2024 and decoupling the game's riding and gliding mechanics in May 2025. By November 2025, Nintendo had narrowed its lawsuit to apply only to older versions of the game. What's left of the original claim now amounts to roughly $66,000 in damages sought — a fraction of what a full injunction would have meant — and it didn't stop Palworld from launching in its complete 1.0 form this July, free of any legal restriction.
Industry watchers read Nintendo's continued patent filings, despite the underwhelming result so far, as an attempt to discourage other studios from making Pokémon-adjacent creature games. So far, it hasn't worked especially well: publisher Funplus recently announced Aniimo, another creature-collecting game, seemingly undeterred by how the Pocketpair case has played out.
