What Is the Nintendo Palworld Lawsuit?
The Nintendo Palworld lawsuit is a patent infringement case filed by Nintendo and The Pokémon Company against Pocketpair, Inc., the Tokyo-based developer of the creature-collecting survival game Palworld. The plaintiffs filed it in the Tokyo District Court on September 18, 2024, and announced it the next day.
It is not a class action, a multidistrict litigation or a copyright case. Only the two plaintiff companies and one defendant company are parties, so no group of consumers or developers can join it.
Nintendo and The Pokémon Company ask the court for an injunction against the alleged infringement and for damages. Reports on the filings say the claims rest on Japanese patents, not on Palworld's creature designs.
“This lawsuit seeks an injunction against infringement and compensation for damages on the grounds that Palworld, a game developed and released by the Defendant, infringes multiple patent rights. Nintendo will continue to take necessary actions against any infringement of its intellectual property rights including the Nintendo brand itself, to protect the intellectual properties it has worked hard to establish over the years.”

Why Was the Nintendo Palworld Lawsuit Filed?
The Nintendo Palworld lawsuit was filed because Nintendo and The Pokémon Company say Palworld infringes their patents on creature-capture and creature-riding gameplay. Their statement names no specific patents. Pocketpair later disclosed the three patents it was told about.
Palworld launched in early access in January 2024 and drew immediate comparisons to Pokémon. The Pokémon Company said that month it would investigate and take appropriate measures if its intellectual property had been infringed.
The plaintiffs chose patents rather than copyright. IGN noted that, after the comparisons, the companies did not file a copyright claim over creature designs. Neither company has publicly explained why the suit arrived nine months after launch.
What Harms Does the Nintendo Palworld Lawsuit Allege?
The Nintendo Palworld lawsuit alleges one legal harm, patent infringement, framed through two gameplay mechanics. Nintendo and The Pokémon Company claim the harm is lost exclusivity over inventions they patented, not injury to people.
Each item below defines the term and then states what the plaintiffs allege. No court has found that any allegation is true.
Patent Infringement
Patent infringement is the use, making or sale of a patented invention without the patent holder's permission.
Nintendo and The Pokémon Company allege that Palworld infringes multiple Japanese patents, according to Nintendo's own announcement. They ask the Tokyo District Court to stop the infringement and award damages.
Pocketpair says it is not liable. Under Japanese patent law, as one games lawyer explained to GamesRadar+, the plaintiffs must show Pocketpair's commercial activity falls within what the patents protect.
Creature Capture Mechanic
A capture mechanic is a game feature that lets a player catch a creature, usually by throwing an item at it.
Pocketpair identified patents about catching creatures in a virtual field as targets of the suit. Palworld lets players throw a ball-like item called a Pal Sphere at wild creatures, similar to a mechanic in Pokémon Legends: Arceus, according to IGN.
Pocketpair removed the ability to summon creatures by throwing a Pal Sphere in a November 30, 2024 patch and said the change came from the litigation.
Creature Riding Mechanic
A riding mechanic is a game feature that lets a player mount a creature or object and travel on it.
Another patent in the suit concerns riding creatures. Dexerto described it as covering smooth switching between riding objects, such as moving from a horse to a flying mount.
Palworld also lets players ride Pals. Pocketpair announced a patch that makes gliding work through a separate glider item rather than a Pal, and said the changes were compromises to avoid disruption.
What Is the Current Status of the Nintendo Palworld Lawsuit?
The current status of the Nintendo Palworld lawsuit is pending, with no ruling, injunction or settlement reported as of October 16, 2026. The case is moving through the Tokyo District Court toward an opinion that reports expect on November 9, 2026.
Patent disputes in Japan commonly take 12 to 18 months to reach a first-instance verdict, patent analyst Florian Mueller told Game Rant in 2024. This case has run longer than that.
Nintendo and The Pokémon Company v. Pocketpair
Nintendo and The Pokémon Company sued Pocketpair, Inc. in the Tokyo District Court seeking an injunction and damages. Reports based on Tokyo court records say the plaintiffs narrowed their claims in November 2025 to older versions of Palworld.
| Court | Tokyo District Court, Japan |
| Case Number | Not published in the reports reviewed |
| Plaintiffs | Nintendo Co., Ltd. and The Pokémon Company |
| Defendant | Pocketpair, Inc. |
| Filed | September 18, 2024 (announced September 19, 2024) |
| Patents in Suit | Three Japanese patents, registered between May and August 2024 |
| Relief Sought | Injunction plus damages of 5 million yen per plaintiff and late-payment interest |
| Scope | Reportedly limited to older Palworld versions since November 2025 |
| Next Event | Hearing reported for October 1, 2026; opinion reported for November 9, 2026 |
| Status | Pending; no ruling reported |

Has the Nintendo Palworld Lawsuit Settled?
No. The Nintendo Palworld lawsuit has not settled, and no court has awarded damages or ordered an injunction as of October 16, 2026.
The plaintiffs seek 5 million yen each, about $32,800 at the time IGN reported it, plus late-payment interest, for the period between each patent's registration and the filing date. Reports differ on whether the figure is per plaintiff or combined, so the total could be 5 or 10 million yen.
The sum is small next to Palworld's sales. The larger stake is the injunction, which would have blocked distribution of the game. Reports say the November 2025 narrowing to older versions makes a block on the current game less likely.
Videogame lawyer Haley MacLean told GamesRadar+ that legal game disputes often settle out of court. She also said nobody could predict a figure without access to all the facts. Any private settlement terms could stay confidential.

Nintendo requested a change to its riding patent while the case was pending, and the amendment was approved and published. Patent analyst Florian Mueller called the added phrase "even when" bizarre, saying he had never seen it in a patent claim in 15 years.
The USPTO Grants a Separate U.S. Summoning Patent
The U.S. Patent and Trademark Office granted Nintendo U.S. Patent No. 12,403,397 in September 2025. The patent covers summoning a sub-character to battle an enemy and sits outside the Japanese lawsuit.
Japan Patent Office Rejects a Related Capture Application
The Japan Patent Office issued a non-final rejection on October 22, 2025 of Nintendo application 2024-031879, citing a lack of inventive step. It named ARK, Monster Hunter 4, Craftopia, Kantai Collection and Pokémon GO as earlier examples.
USPTO Director Orders Re-Examination of the U.S. Patent
USPTO director John Squires personally ordered a re-examination of Nintendo's U.S. Patent No. 12,403,397 in November 2025. Eurogamer called it a rare step, pointing to prior art in older Konami and Nintendo patents.
Plaintiffs Narrow Their Claims to Older Palworld Versions

Tokyo Session Scheduled; Outcome Not Yet Reported
Reports scheduled the next Tokyo District Court session in the Nintendo and Pocketpair case for October 1, 2026. No coverage of its outcome, and no ruling, had been found as of October 16, 2026.
What Evidence Matters in the Nintendo Palworld Lawsuit?
The evidence that matters most in the Nintendo Palworld lawsuit is prior art, meaning earlier games or patents that show the claimed mechanics already existed. Both sides argue over validity as well as infringement.
Pocketpair's reported prior-art list includes ARK: Survival Evolved, Tomb Raider, Zelda, Titanfall 2, Rune Factory 5 and the Pixelmon and NukaMon mods. Nintendo argued that mods should not count as publicly known technology, according to Windows Central.
Patent attorney Kirk Sigmon told PC Gamer that broad claims invite prior-art attacks, because a claim such as controlling a player character in a virtual space can be matched by almost any game. If the claims fall, Nintendo could lose the patents themselves.
How Has Pocketpair Responded to the Nintendo Palworld Lawsuit?
Pocketpair has responded to the Nintendo Palworld lawsuit by contesting the patents and changing Palworld. It has said it will assert its position through legal proceedings and that indie developers should not be discouraged from pursuing creative ideas.
The studio said it cleared legal checks in Japan before launch, and its communications director told a Game Developers Conference panel the patent claim came as a shock. The studio also hired security guards after the filing.
Pocketpair has made gameplay changes and, per its own blog, said they were compromises to avoid disruption. It has not admitted infringement.
Is the Nintendo vs Palworld Lawsuit the Same as the Patent Office Reviews?
No. The Nintendo vs Palworld lawsuit is a court case in Tokyo, while the patent office reviews are separate administrative proceedings that examine whether related Nintendo filings deserve patent protection.
The reviews matter because a patent that fails an examiner's test is harder to enforce. Windows Central noted that judges often respect examiners' technical findings, even though the findings do not bind the court.
| Proceeding | Forum | What It Decides | Reported Status |
|---|---|---|---|
| Nintendo and The Pokémon Company v. Pocketpair (this page) | Tokyo District Court | Infringement, validity, injunction and damages | Pending; opinion reportedly expected November 9, 2026 |
| Application 2024-031879 | Japan Patent Office | Whether a related capture application is patentable | Non-final rejection, October 22, 2025 |
| U.S. Patent No. 12,403,397 | USPTO | Whether a granted summoning patent stays valid | Non-final rejection of all 26 claims, March 2026 |
A games lawyer told GamesRadar+ that Nintendo previously won a Japanese patent case against the company Colopl in 2017. That earlier case is distinct from this one and does not bind it.
