What Is the Palworld Lawsuit?
The Palworld lawsuit is a patent infringement case that Nintendo and The Pokémon Company filed against the game developer Pocketpair. Nintendo Co., Ltd. and The Pokémon Company filed it in the Tokyo District Court on September 18, 2024, according to Nintendo's own announcement the next day.
The suit targets Palworld, a creature-collecting survival game that Pocketpair, Inc. released in early access in January 2024. Nintendo's announcement said the plaintiffs seek an injunction against infringement and compensation for damages.
The case is a dispute between companies under Japanese patent law. It is not a class action, and no group of similarly situated claimants can join it.
Why Was the Palworld Lawsuit Filed?
The Palworld lawsuit was filed because Nintendo and The Pokémon Company say Palworld infringes their patents on capturing creatures, aiming a capture item, and switching between ridable creatures. Their announcement said Palworld infringes multiple patent rights but did not name the patents.
Pocketpair later published a report that named three Japanese patents. According to PC Gamer, each was filed after Palworld's January 2024 release, but each continues a series of Nintendo filings from 2021, made during the development of Pokémon Legends: Arceus.
IP attorney Kirk Sigmon told PC Gamer that continuation filings let a patent holder draft claims aimed at a specific target. Pocketpair has said the suit came as a shock because its own legal checks in Japan had cleared the game before release.
These are the plaintiffs' allegations. Pocketpair disputes them, and no court has ruled on them.
What Harms Does the Palworld Lawsuit Allege?
The Palworld lawsuit alleges three distinct harms: patent infringement, monetary damages, and continuing infringement that Nintendo wants stopped. Each harm is defined in plain language below, followed by what the plaintiffs allege. The allegations come from Nintendo's announcement, Pocketpair's report, and press coverage, and no court has made findings on them.
Patent Infringement
Patent infringement is the unauthorized making, using, or selling of an invention that another party holds a patent on.
Nintendo and The Pokémon Company allege that Palworld uses inventions covered by three Japanese patents. Two patents concern creature capture and release, including aiming a capture item and showing the chance of capture. The third concerns switching between ridable characters.
Press coverage ties the capture patents to throwing a Pal Sphere to catch and release Pals. Pocketpair disputes the claims, and its defense is described in a later section.
Monetary Damages
Monetary damages are a payment a court can order to compensate a patent holder for losses caused by infringement.
Pocketpair reported that each plaintiff asked for 5 million yen, with late payment damages added. The claim covers losses between each patent's registration and the filing of the suit. How the amount is valued under the narrowed claims is covered in the settlement section.
Continuing Infringement
Continuing infringement is the ongoing use of a patented invention after a claim of infringement has been made, which a plaintiff can ask a court to stop through an injunction.
Nintendo and The Pokémon Company asked the Tokyo District Court for an injunction, which would halt sales of Palworld until the disputed mechanics are removed. The announcement of the suit said it seeks an injunction against infringement.
Pocketpair has changed several disputed mechanics since the suit began. Those changes are the reason the plaintiffs later narrowed their claims to older versions of the game, as the status section explains.
What Is the Current Status of the Palworld Lawsuit?
The current status of the Palworld lawsuit is pending in the Tokyo District Court, with no judgment reported. Coverage reviewed for this page ran through June 2026. It could not confirm what happened at a court session reported for October 1, 2026.
The status of a separate U.S. patent proceeding is also listed, because press coverage often links it to the lawsuit.
Nintendo Co., Ltd. and The Pokémon Company v. Pocketpair, Inc.
The Tokyo District Court is hearing the Palworld patent case under Japanese law, so U.S. terms such as MDL and class certification do not apply. Most detail below comes from Nintendo's announcement, Pocketpair's statements, and Games Fray's reading of court records.
| Court | Tokyo District Court, Japan |
| Plaintiffs | Nintendo Co., Ltd. and The Pokémon Company |
| Defendant | Pocketpair, Inc. |
| Filed | September 18, 2024 (announced September 19, 2024) |
| Claim Type | Patent infringement, with a request for an injunction and damages |
| Patents Asserted | Japanese Patent Nos. 7545191, 7493117, and 7528390 |
| Scope Change | Claims narrowed to older Palworld versions in November 2025, per Games Fray |
| Reported Schedule | Evidence session October 1, 2026, and court opinion expected November 9, 2026, per Games Fray via Wccftech |
| Judgment | None reported |
| Latest Reporting Reviewed | June 2026 |
The reported November 9, 2026 opinion date has not been confirmed by the court or by Nintendo, so treat it as an expectation, not a fixed deadline.
U.S. Patent No. 12,403,397 reexamination (USPTO)
This is a separate administrative review of a U.S. patent, not a lawsuit, and it is not one of the three Japanese patents in the Tokyo case. USPTO Director John Squires personally ordered the reexamination in November 2025, after the office granted the patent in September 2025.
| Agency | U.S. Patent and Trademark Office |
| Patent | U.S. Patent No. 12,403,397, summoning a sub-character to battle an enemy |
| Granted | September 2025 (applied for March 2023) |
| Reexamination Ordered | November 2025, by Director John Squires |
| Prior Art Cited | Earlier filings by Konami (2002) and Nintendo (2019) in the order, and later also Bandai Namco |
| Latest Action | Non-final rejection of all 26 claims, reported spring 2026 |
| Finality | Not final; Nintendo can respond, amend the claims, or appeal |
Coverage disagrees on the patent number in a few places. Eurogamer and GamesRadar both give 12,403,397, which this page uses.
Did Palworld Win the Lawsuit?
No. Pocketpair has not won the Palworld lawsuit, and Nintendo has not won it either, because the Tokyo District Court has not issued a judgment.
No settlement between the parties has been reported in the coverage reviewed. Headlines that say Nintendo has a "0% chance" are analysts' predictions, not rulings, and only the court can decide the outcome.
The money at stake is small for a case of this profile. Pocketpair reported that each plaintiff sought 5 million yen, about $66,000 combined at 2024 exchange rates. After the claims were narrowed to older versions, Games Fray calculated that Nintendo could win at most about 5 million yen, roughly $30,000.
Patent analyst Florian Mueller wrote that he saw no path to victory for Nintendo over any current or very recent Palworld version, according to Automaton. That is commentary, and the court has not adopted it.
The cost of defending is a separate matter. IP attorney Kirk Sigmon told PC Gamer that patent litigation can burn millions of dollars, even when the damages claimed are small.

USPTO Issues Non-Final Rejection of All 26 Claims in Nintendo's Summoning Patent
A U.S. patent examiner issued a non-final rejection of all 26 claims in U.S. Patent No. 12,403,397, according to reports from Games Fray and Nintendo Life in spring 2026. The examiner combined earlier filings by Nintendo, Konami, and Bandai Namco as prior art. Nintendo can respond, amend the claims, or appeal.
USPTO Director Orders Reexamination of Nintendo's Summoning Patent
USPTO Director John Squires personally ordered reexamination of U.S. Patent No. 12,403,397 in November 2025. His order found a substantial new question of patentability based on earlier patents from Konami and Nintendo. Eurogamer, citing Games Fray, described the step as rare.
Nintendo and The Pokémon Company Narrow the Palworld Claims to Older Versions
Nintendo and The Pokémon Company narrowed their Tokyo District Court claims in November 2025 so that they cover only older Palworld versions, according to Games Fray's reading of court records. Automaton reported the change likely followed Pocketpair's preventive updates to the disputed mechanics.
Japan Patent Office Issues Non-Final Rejection of a Nintendo Capture Patent Application
The Japan Patent Office rejected a Nintendo application on monster capture and item-throwing mechanics, according to a Eurogamer report that said the decision came weeks before the U.S. reexamination order. The rejection was not final and rested on prior art in earlier games. Eurogamer said the patent might prove important to the lawsuit but did not give its number.
USPTO Grants Nintendo U.S. Patent No. 12,403,397
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 was applied for in March 2023. GamesRadar noted that Nintendo had obtained new patents while the Tokyo case against Pocketpair was ongoing.
Nintendo and The Pokémon Company Reword One Asserted Patent
Nintendo and The Pokémon Company changed the wording of one of the asserted Japanese patents in July 2025, according to IGN. GamesRadar identified it as the patent on riding or mounting creatures. Pocketpair had previously changed how gliding works in Palworld in May 2025.
Palworld Update Changes How Players Glide
A Palworld update in May 2025 changed gliding so that players use Pal-buffed glider equipment instead of directly grabbing onto Glider Pals, according to IGN. IGN listed it among Pocketpair's changes to mechanics disputed in the lawsuit.
Pocketpair Says the Nintendo Lawsuit Came as a Shock
Pocketpair communications director John Buckley said at the March 2025 Game Developers Conference that the lawsuit came as a shock because patent infringement was something no one had considered. He said Pocketpair's legal checks in Japan had cleared Palworld before release.
Pocketpair Files Its Invalidity Defense Against All Three Patents
Pocketpair submitted its invalidity arguments to the Tokyo District Court on February 21, 2025, according to Games Fray. It argued that none of the three asserted patents described anything new, citing games such as Craftopia, ARK, Titanfall 2, and Far Cry 5.
Pocketpair Files Its Non-Infringement Arguments in Tokyo
Pocketpair submitted its non-infringement arguments to the Tokyo District Court on January 31, 2025, according to Games Fray. These arguments apply only if Pocketpair fails to show that the patents are invalid.
Palworld Patch Removes Throwing Pal Spheres to Summon Pals
A November 2024 Palworld patch removed the ability to summon Pals by throwing a Pal Sphere, according to IGN. Pals now appear next to the player when summoned. GamesRadar reported that Pocketpair had made certain compromises in development to avoid disruptions during the legal battle.
Pocketpair Publishes a Report Naming the Three Patents and the Damages Sought
Pocketpair published a report in early November 2024 that named Japanese Patent Nos. 7545191, 7493117, and 7528390, the three patents in the Nintendo suit. It said each plaintiff sought 5 million yen plus late payment damages and that Nintendo also sought an injunction. Nintendo World Report covered the report on November 8, 2024.
Nintendo Announces the Patent Suit and Pocketpair Responds
Nintendo announced on September 19, 2024 that it and The Pokémon Company had sued Pocketpair in the Tokyo District Court. Pocketpair said it had not been told which patents were at issue and would investigate the claims through appropriate legal proceedings.
Nintendo and The Pokémon Company File the Palworld Patent Lawsuit
Nintendo Co., Ltd. and The Pokémon Company filed a patent infringement lawsuit against Pocketpair, Inc. in the Tokyo District Court on September 18, 2024. Nintendo's announcement said the suit seeks an injunction against infringement and compensation for damages.
Pocketpair Releases Palworld in Early Access
Pocketpair released Palworld in early access in January 2024, according to PC Gamer. The game drew large audiences and was widely described as Pokémon with guns. The patents later asserted against it were filed after this release.
What Is Pocketpair's Defense in the Palworld Lawsuit?
Pocketpair's defense in the Palworld lawsuit rests on two arguments: the three patents are invalid, and Palworld does not infringe them. According to Games Fray's reading of the Tokyo District Court filings, the invalidity argument comes first and the non-infringement argument applies only if the first one fails.
For invalidity, Pocketpair points to earlier games that it says already contained each patented idea. The table shows the prior art it reportedly cited for each patent.
Outside court, Pocketpair has vowed to defend itself and keep updating Palworld, according to IGN. Its communications director said the suit came as a shock because the game had passed legal checks in Japan before release.
| Patent | What it covers | Prior art Pocketpair cited |
|---|---|---|
| JP7545191 | Capturing creatures and releasing them into battle | Craftopia, Titanfall 2, Far Cry 5, Tomb Raider, Octopath Traveler |
| JP7493117 | Aiming a capture item and calculating the capture chance | Pocket Souls (a Dark Souls 3 mod), NukaMon (a Fallout 4 mod), Monster Super League, Nexomon, Craftopia |
| JP7528390 | Switching ridable characters | ARK, which Pocketpair said needs no other game combined with it |
These are Pocketpair's arguments as reported, and the court has not ruled on them.
How Does the Palworld Lawsuit Compare to Related Cases?
The Palworld lawsuit compares to related matters as a Japanese civil patent suit, while the other items below are patent office reviews or a separate company's case. Each has its own forum, parties, and outcome, and a result in one does not decide another.
| Matter | Forum | Subject | Status |
|---|---|---|---|
| Nintendo and The Pokémon Company v. Pocketpair | Tokyo District Court | Three Japanese patents on capture and riding | Pending, as described above |
| U.S. Patent No. 12,403,397 reexamination | U.S. Patent and Trademark Office | A U.S. summoning patent, not asserted in the Tokyo case | Non-final rejection of all 26 claims reported |
| Nintendo capture patent application | Japan Patent Office | Monster capture and item-throwing mechanics | Non-final rejection reported in late 2025 |
| Sega v. Bank of Innovation | Japan (as reported) | Five patents on gacha game mechanics, with 1 billion yen sought | Filed about a month after the Palworld suit; outcome not confirmed |
The Sega case involves a different plaintiff, defendant, and game, so it has no legal effect on Palworld. Anyone with a different patent dispute should ask a licensed attorney about deadlines.

What is the Palworld lawsuit about?
The Palworld lawsuit is about patents. Nintendo and The Pokémon Company sued Pocketpair in the Tokyo District Court on September 18, 2024, alleging that Palworld infringes three Japanese patents on creature capture and riding mechanics.
Is the Palworld lawsuit a class action or an MDL?
The Palworld lawsuit is neither a class action nor an MDL. It is a single patent case between two plaintiffs and one defendant in a Japanese court, so U.S. class and multidistrict procedures do not apply.
Did Palworld win the lawsuit against Nintendo?
No court has ruled yet, so Palworld has neither won nor lost the lawsuit. The Tokyo District Court has not issued a judgment, and no settlement has been reported. A court opinion was reportedly expected on November 9, 2026.
How much is Nintendo suing Palworld for?
Nintendo and The Pokémon Company are suing Pocketpair for 5 million yen each, plus late payment damages, according to Pocketpair's report. That is about $66,000 combined, and Games Fray estimates the maximum is about $30,000 after the claims were narrowed.
Did Palworld change its game because of the Nintendo lawsuit?
