What Happened to Nintendo Palworld Lawsuit?
Nintendo and The Pokémon Company filed a patent infringement lawsuit against Palworld developer Pocketpair in September 2024, alleging infringement of gameplay mechanics rather than creature designs. Despite initial concerns, Pocketpair made game adjustments, and the lawsuit's scope has narrowed to older game versions, with recent patent office rejections further weakening Nintendo's position as Palworld continues its commercial success.
Quick Answer
Nintendo and The Pokémon Company officially sued Palworld developer Pocketpair in September 2024, not for copyright infringement over creature likenesses, but for alleged patent infringement related to specific gameplay mechanics like capturing and summoning Pals. As of July 2026, the lawsuit is ongoing in Japanese courts, but its commercial impact is considered minimal, with Pocketpair having patched out disputed mechanics and Nintendo facing rejections on related patent applications from both US and Japanese patent offices. Palworld successfully launched its 1.0 version in July 2026 without legal restrictions.

🔍Deep Dive Analysis
The legal saga surrounding Palworld, often dubbed 'Pokémon with guns,' began shortly after its explosive early access launch in January 2024. The game, developed by Japanese studio Pocketpair, quickly garnered immense popularity, selling millions of copies and drawing immediate comparisons to Nintendo's beloved Pokémon franchise due to its monster-taming gameplay.
Initially, The Pokémon Company issued a statement in January 2024, indicating it would investigate any acts infringing on its intellectual property rights related to Pokémon. Many observers anticipated a copyright infringement lawsuit over the visual similarities of Palworld's 'Pals' to Pokémon characters. However, on September 18, 2024, Nintendo and The Pokémon Company filed a lawsuit in the Tokyo District Court against Pocketpair, specifically alleging infringement of multiple patent rights related to gameplay mechanics, rather than copyright or trademark violations. These patents reportedly covered functional gameplay elements such as capturing and summoning creatures by throwing an item, a real-time capture-probability indicator, and mounting creatures for traversal.
Pocketpair responded swiftly, stating they had received notice of the lawsuit but were unaware of the specific patents they were accused of infringing. The studio expressed regret over the situation, emphasizing its commitment to game development and its fans. In response to the legal pressure, Pocketpair began implementing changes to Palworld's gameplay. By November 2024, patch v0.3.11 removed the mechanic allowing players to throw a sphere to summon a captured Pal into battle. Further, by May 2025, the ability for players to glide using their Pals was also removed in patch v0.5.5, with players now requiring a separate glider. These adjustments effectively removed the disputed mechanics from the current version of the game.
A significant turning point occurred in November 2025 when the plaintiffs narrowed their claims in the Japanese lawsuit to older versions of Palworld, effectively removing the threat of an injunction against the game's current or future versions. Concurrently, Nintendo faced challenges with related patents. In March 2026, the U.S. Patent and Trademark Office (USPTO) issued a non-final Office Action rejecting all 26 claims of a related Nintendo patent (No. 12,403,397) covering a summon-and-fight mechanic, citing obviousness in light of earlier patents, including some of Nintendo's own. This was followed by the Japanese Patent Office (JPO) rejecting a Nintendo patent application (No. 2026-019762) in July 2026, describing an 'in-game monster-capturing system,' citing prior art including a 2013 Pokémon fan game. Another related Nintendo patent application (No. 2024-031879) was also rejected by the JPO in July 2026 for lack of inventive step, citing various existing games.
As of July 23, 2026, the lawsuit in the Tokyo District Court is ongoing, with a hearing scheduled for October 1, 2026. However, the commercial implications for Pocketpair appear minimal. The damages sought by Nintendo and The Pokémon Company are a combined 10 million yen (approximately $66,000 USD), a sum considered negligible compared to Palworld's estimated revenue of over $700 million from more than 30 million copies sold across platforms. Palworld successfully launched its full 1.0 version on July 10, 2026, without any legal restrictions impacting its release or continued development.
