Pocketpair identified three Japanese patents and says it disputes the claims. The patents and the game changes Pocketpair later announced help explain what the dispute concerns, but the available sources do not establish how a court has ruled or whether any of the patents are valid or infringed.
What is the lawsuit about?
Nintendo said it and The Pokémon Company filed suit against Pocketpair in Tokyo District Court on September 18, 2024; Nintendo published its announcement the next day. The companies allege that Palworld infringes multiple patent rights and seek an injunction and damages. Those are the plaintiffs’ claims, not a judgment. Nintendo’s announcement identifies the case as a patent-infringement action.
That distinction matters: the public case description cited here is about patents, not a ruling about copyright, character designs, or whether Palworld copied Pokémon. Pocketpair initially said it had not been told which patents were at issue, then identified three in its November 2024 report. The statements are from different points in the case, rather than contradictory accounts. Pocketpair’s report provides the patent numbers and its account of the requested relief.
Which patents did Pocketpair identify?
Pocketpair’s November 8, 2024 report listed the following Japanese patent numbers and dates. The dates are the application and registration dates reported by Pocketpair; the fact that the patents were registered does not itself establish that Palworld infringes them or resolve Pocketpair’s challenge to their validity.

These identifiers and dates come from Pocketpair’s November 2024 disclosure. Pocketpair says Palworld was released on January 19, 2024, before the listed application dates. The chronology alone does not determine the legal questions in the case; the sources cited here do not provide the court’s analysis of the patent claims or their application to the game.
What does each patent cover?
The sources available here establish the three patent numbers, but do not provide the patent claim texts alongside the plaintiffs’ specific infringement contentions. That means it would be misleading to confidently assign one patent to a particular Palworld feature based only on summaries. In a patent case, the operative questions include what the relevant claims cover, whether those claims are valid, and whether the accused product falls within them. No court finding on those questions is established by the cited material.
The dispute can therefore inform readers about the legal questions at stake without proving a broader claim about the games’ characters or overall resemblance. A patent case evaluates the asserted patent rights and alleged infringement; it does not, by itself, decide an unasserted copyright claim.

What damages and remedies did the plaintiffs seek?
Pocketpair said the plaintiffs sought an injunction and ¥5 million plus late-payment damages from each plaintiff, or ¥10 million in principal across both plaintiffs. This is the amount Pocketpair reported the plaintiffs were seeking, not damages awarded by a court. Pocketpair’s report is the source for that figure.
What changes did Pocketpair make to Palworld?
In a May 8, 2025 statement, Pocketpair said litigation had led it to change two mechanics. These are Pocketpair’s descriptions of its own design decisions; they do not establish that a court found either mechanic infringed a patent.
- Summoning: Pocketpair said patch v0.3.11 removed throwing Pal Spheres to summon Pals and changed summoning to a static action beside the player.
- Gliding: Pocketpair said patch v0.5.5 changed the mechanic so a glider, rather than a Pal, performs the glide.
Pocketpair also said it disputes the infringement claims and asserts that the patents are invalid. Those are the defendant’s positions, not judicial conclusions. Pocketpair’s May 2025 statement describes both its position and the game changes.

A patent-attorney explainer published July 14, 2026 described the case as pending and reported that, as of July 8, there had been no judgment, settlement, or injunction. It also listed an October 1 technical briefing and a November 9 preliminary view as scheduled milestones, based on media reporting. The explainer does not establish what happened at the October 1 briefing. As of October 8, the sources cited here do not verify an outcome from that event or a later court disposition; the November 9 date remains a reported scheduled milestone, not a confirmed result.
Separately, June 2026 coverage reported that the plaintiffs had amended the scope of their claims to target older versions of Palworld and described the action as limited to Japan. That is a report about the litigation, not a ruling on infringement or the patents’ validity. GamesRadar’s June 2026 report also attributes a damages assessment to an analyst; it should not be mistaken for a court’s damages calculation.

If resolved by a court, the case could address the validity and scope of the asserted Japanese patents and whether the accused Palworld versions infringed them. The record described in the cited sources does not establish those answers. Nor does the case, as publicly described there, settle broader questions about character copying, copyright, or the overall similarity of the two games.
The practical evidence available so far is narrower: Nintendo and The Pokémon Company filed a patent suit; Pocketpair named three patents, challenged the claims, and made changes to summoning and gliding that it says were related to the litigation. The reported procedural milestones should not be presented as outcomes until a verified court update establishes what happened.
