Nintendo's Pokémon patent lawsuit takes another hit

Nintendo and The Pokémon Company have suffered another setback in their legal battle to patent specific gameplay mechanics. This time, the Japan Patent Office has rejected their application for a patent covering Poké Ball-like capture and release mechanics on touchscreen devices.

Patent application and rejection

The patent application filed by Nintendo and The Pokémon Company covered the use of a "touch panel" for capturing characters in a touchscreen game. The goal was to secure a patent that would let them push back against competitors such as Palworld Mobile, which uses similar gameplay mechanics.

The Japan Patent Office rejected the application on the grounds that it lacked an "inventive step"; in other words, it did not offer any significant innovation beyond existing mechanics. This is an important development in the legal fight, as it limits Nintendo's ability to claim and defend such gameplay systems against competitors.

The impact on Palworld Mobile

Palworld Mobile, the game this patent was specifically aimed at, is an upcoming title focused on capturing and battling monsters, similar to the mechanics used in Pokémon games. Despite Nintendo's concerns, the game has already faced debate over the originality of its monster designs, which some fans felt were too close to existing Pokémon.

Nintendo's lawsuit against developer Pocketpair, the studio behind Palworld, is a direct result of those concerns. Nintendo has tried to gain an advantage in this competitive battle through patents, but so far that plan does not appear to be working.

The lawsuit since 2024

The ongoing legal dispute began in January 2024, shortly after Palworld's release. Nintendo filed a lawsuit against Pocketpair over alleged patent infringement, suggesting it wants to maintain what it sees as an unfair advantage in the market. That has led to a complex debate over what counts as intellectual property infringement in the video game industry.

At first, the concern centered on Palworld's monster designs, which many felt looked strikingly similar to Pokémon. However, Nintendo then shifted toward pursuing patents, giving it a legal strategy with potentially broader consequences.

The future of the patent battle

With the rejection of its patent application, Nintendo may have the option to revise and resubmit its claims. The company has reportedly already made a similar attempt once before in February 2026. The question now is whether it can add substantially different inventive elements that might have a chance of approval.

The case also has wider implications for the industry, as it could shape how intellectual property disputes in game development unfold, especially given the popularity of monster-catching games.

The outcome of this legal battle will likely influence how gameplay mechanics can be claimed and protected by companies in the future. It remains unclear how Nintendo will respond to this latest setback and what impact it will have on its strategic plans for franchise expansion into new markets such as mobile gaming.
