On July 20, 2026, Japan's Patent Office (JPO) issued a formal refusal for a Nintendo touchscreen patent application covering monster-catching gameplay mechanics. The decision came just ten days after Palworld's full 1.0 launch and deepens an already closely watched legal dispute between Nintendo and Palworld developer Pocketpair.
The patent examiner has closed regular examination on this filing. Nintendo retains legal options, but the path forward is narrower than before.

What Was Rejected
The refused application described touchscreen-specific gameplay mechanics, including:
- ▶Character movement through touchscreen input
- ▶Capture item usage interfaces
- ▶Creature summoning and command systems
- ▶Monster capture actions both during and outside combat
Patent analyst Florian Mueller described the significance of the ruling clearly:
""This 'decision of refusal' terminates regular patent examination. The patent examiner is done with this." — Florian Mueller (via OtakuKart)
Nintendo now has a three-month window to choose one of three responses:
| Option | Description |
|---|---|
| Appeal | Request review by a JPO panel of administrative judges |
| Divisional application | File a narrower, revised claim set |
| Abandon | Drop this specific application |
The Prior Art Ruling Is the Precedent Worth Watching
The most consequential part of the decision is not the outcome itself but the reasoning. Nintendo argued that gameplay footage from the fan project Pokémon Generations should be excluded as prior art because the fan project allegedly infringed Pokémon-related copyrights.
The examiner rejected that argument. Under Japanese patent law, whether a document or recording infringes copyright has no bearing on whether it qualifies as prior art for novelty and inventive step assessments. Publicly accessible material is evaluated on accessibility, not on its copyright status.
This ruling has implications beyond Palworld. If the principle holds — and it is consistent with how patent offices in many jurisdictions handle this question — it means game developers cannot easily exclude openly distributed fan content from the prior art record, even when the copyright holders of the source material object. For indie developers facing broad patent claims from platform holders, that is a meaningful data point.
How This Fits Into the Bigger Dispute
This rejected patent is not one of the patents currently named in Nintendo's active lawsuit against Pocketpair. The ongoing case is based on separate filings in the same family. Nintendo can continue that lawsuit regardless of today's outcome.
However, the rejected application belonged to the same patent family as the litigation patents. Industry observers, including Games Fray, had noted that its touchscreen focus made it a potential tool for Nintendo in disputes involving mobile monster-catching games — including the still-in-development Palworld Mobile.
Because this refusal removes it from Nintendo's reachable portfolio (absent a successful appeal), one possible enforcement vector for mobile is now closed, at least temporarily.

| Sept–Oct 2024 | Nintendo files patent infringement suit against Pocketpair |
| July 10, 2026 | Palworld 1.0 ships on PC, PS5, Xbox, and Mac (Metacritic: 86) |

What Each Side Has Said
Nintendo
Nintendo has not issued a public statement about the JPO refusal. The company retains the right to appeal within three months and continues to pursue its current lawsuit on the patents already named in that case.
Pocketpair
Pocketpair has not commented on the JPO decision specifically. The studio has been focused on Palworld's 1.0 post-launch momentum — the game holds a Metacritic score of 86 and an Overwhelmingly Positive Steam rating — and continues development on Palworld Mobile in partnership with Krafton and PUBG Studios.

Industry Reaction
Responses from the gaming and legal communities have largely focused on three themes:
The prior art precedent. Patent attorneys and analysts have flagged the fan-video ruling as the most durable part of the decision. It reinforces that courts and patent offices in Japan will not let copyright arguments short-circuit prior art analysis.
What it means for mobile. With Palworld Mobile in active development and targeting touchscreen platforms, removing a touchscreen-specific patent from Nintendo's arsenal is seen as reducing one category of legal risk for Pocketpair and its partners.
Caution about the ongoing lawsuit. Several commentators note that the refused patent was never part of the current case. The lawsuit proceeds on its own timeline, and this outcome does not signal how that suit will resolve.
The Bottom Line
The JPO's refusal is a setback for Nintendo's broader patent strategy in the touchscreen monster-catching space, but it does not touch the active litigation. Nintendo retains multiple options: it can appeal, file a narrower divisional application, or let this specific filing lapse while continuing its suit on other patents.
For Pocketpair, the ruling reduces one category of potential future exposure for Palworld Mobile without resolving the central dispute. The core question — whether Palworld's console and PC mechanics infringe the patents actually named in the lawsuit — remains open.
If Nintendo appeals and loses again, the precedent around fan-game footage as prior art will be further cemented. That outcome would matter to indie developers far beyond this particular case.
