Japanese patent officials reject one of Nintendo's Pokémon patent applications for being too similar to ARK, Monster Hunter, and—embarrasingly—Pokémon Go

The Japanese Patent Office rejected a Nintendo patent application (JP 2024-031879) for certain game mechanics, citing a lack of inventive step due to similarities with prior art from other games. While this specific application is not directly asserted in Nintendo's ongoing lawsuit against Palworld developer Pocketpair, it is related to patents that are, and the rejection could provide Pocketpair with leverage to challenge the validity of Nintendo's broader intellectual property claims. This development underscores the challenges of IP enforcement in the rapidly evolving gaming sector and could impact the trajectory of the high-profile litigation.

Analysis

The Japanese Patent Office (JPO) recently rejected Nintendo's patent application JP 2024-031879, citing a lack of "inventive step" due to its similarity to existing prior art. This application, detailing mechanics for aiming and throwing items to capture or battle creatures, was deemed not novel enough, with the JPO referencing games like ARK, Monster Hunter, Craftopia, and even Nintendo's own Pokémon Go. This decision underscores the increasing difficulty in securing broad intellectual property protections for game mechanics.

While JP 2024-031879 is not directly asserted in Nintendo's ongoing lawsuit against Palworld developer Pocketpair, it is a related "child" or "parent" application to patents that are central to the litigation. This rejection, therefore, represents a strategic setback for Nintendo, potentially weakening its overall intellectual property claims regarding creature-capturing and battling mechanics. The moderately negative sentiment associated with this news reflects this challenge.

The JPO's ruling provides significant leverage for Pocketpair, as patent lawsuit judges often consider JPO examiner decisions in their deliberations. Pocketpair can formally request the presiding judge to consider this refusal, potentially enabling a similar investigation into the validity of the patents Nintendo is asserting. This development highlights the evolving landscape of IP enforcement within the dynamic media and entertainment sector.

Key Decisions for Investors

• Monitor the progress of Nintendo's potential appeal against the JPO's rejection and its broader implications for their intellectual property portfolio, particularly concerning core game mechanics.
• Evaluate the precedent this JPO decision sets for the enforceability of mechanics-based patents across the gaming industry, potentially impacting other developers and publishers.
• Assess the increased litigation risk and competitive dynamics within the video game sector, as challenges to established IP claims may become more frequent.
