In November 2024, Pocketpair—developer of Palworld—publicly disclosed the specific patents cited by Nintendo Co., Ltd. and The Pokémon Company in their infringement claim. These include Japanese patents numbered 7545191, 7493117, and 7528390, all filed between May and July 2024. The patents center on gameplay mechanics, such as throwing an object to capture creatures or mounting/riding characters.
Nintendo Shutting Down Palworld?
Nintendo and The Pokémon Company filed suit on September 18/19, 2024, in Tokyo District Court seeking both an injunction to stop Palworld’s distribution and monetary damages for alleged patent violations.
The developer has responded by stating it believes the patents are invalid and has modified certain in-game features under legal pressure.

Patent Palworld — The Mechanics Under Fire
At the heart of the dispute are patents covering monster-capture and ride/mount mechanics. Nintendo’s filings claim systems where a player throws an object (e.g., a “ball”) to capture or trigger combat with creatures, or switches seamlessly between riding different objects or characters.
The Verge
Pocketpair argues that such mechanics predate Nintendo’s filings, citing earlier games and mods as prior art.
Nintendo Suing Palworld — Legal Battle Details
The lawsuit seeks to enforce Nintendo’s patents and block Palworld’s operations unless a settlement is reached. However, the case has seen significant setbacks: one key Japanese divisional application (No. 2024-031879) was issued a Notice of Reasons for Rejection by the Japan Patent Office (JPO) for lacking inventive step, and 22 out of 23 related claims were rejected by the U.S. Patent and Trademark Office (USPTO).
These developments raise questions about Nintendo’s legal position and the broader question of whether gameplay mechanics can be patented.
If you like, I can draft a timeline of key legal milestones in this case or compare this dispute with past major gaming-patent cases (e.g., Sega vs. Fox).
