A new development has come in the ongoing Nintendo–Palworld case, making headlines across the gaming and anime worlds.

This decision follows months of tension and debate surrounding alleged similarities between Palworld and Nintendo’s Pokémon franchise. Keep reading to learn more about this Latest IP news, the JPO’s decision, and what it could mean for the future of both companies.
What Is the Background of the Nintendo Palworld patent news?
To understand the reasons behind the Japan Patent Office’s (JPO) recent rejection of Nintendo’s patent application, it’s important to look at the ongoing legal dispute between Nintendo and Pocketpair — two well-known names in the gaming industry. Pocketpair, the developer behind the hit game Palworld, has been in the spotlight since September 2024, when Nintendo and The Pokémon Company filed a lawsuit against it in the Tokyo District Court. Nintendo claimed that Palworld had infringed on several of its patents related to game mechanics, particularly those involving creature-catching, companion interaction, and ride-based gameplay features — mechanics that closely resemble those used in the Pokémon franchise.
Pocketpair, however, denied all claims and stated that it had not been officially informed about which specific patents were being challenged. The case quickly grabbed global attention after Palworld—often described by fans as “Pokémon with guns”- became a viral gaming sensation. This surge in popularity increased comparisons between the two franchises and brought the legal battle into the international spotlight.

What Was the Japan Patent Office’s Decision on Nintendo’s Patent Application?
In the Nintendo Palworld patent news, the recent update came where the Japan Patent Office (JPO) officially rejected one of Nintendo’s patent Filing that was linked to its ongoing legal dispute with Pocketpair. The rejection was because of the lack of inventive step, meaning the claimed invention did not meet the originality or innovation standards required for a new patent.
According to the JPO’s examination report, the features explained in Nintendo’s application, which related to creature-catching, interaction, and riding mechanics within a game environment, were found to be too similar to existing technologies and concepts already seen in existing games. These games were determined to have already introduced similar gameplay mechanics before Nintendo’s filing, making the company’s claim insufficiently novel.
The JPO’s decision, however, is not final. Nintendo still has the right to appeal or amend the claims in the application in an effort to demonstrate that its invention contains unique, innovative elements that distinguish it from prior works. Nonetheless, this rejection represents a setback for Nintendo, as the patent was considered part of its broader legal and enforcement strategy in the ongoing dispute with Pocketpair over Palworld.
Conclusion
The recent decision by the Japan Patent Office to reject Nintendo Co., Ltd.’s patent application linked to the Palworld case underscores how originality and inventive step remain critical in gaming‐industry IP disputes. While this move may challenge Nintendo’s enforcement position, it also highlights the complexity of protecting game mechanics through patents.
