Nintendoโs lawsuit to take down Pocketpairโs Palworld suffered a devastating blow in court. If you know anything about Nintendo, itโs that the company is incredibly litigious, so when Palworld arrived in January 2024, it took notice. If youโve never played it, Palworld shares a lot in common with another franchise you’re likely familiar with: Pokรฉmon. The premise is different, as the adorable critters donโt rely on magic or traits to fight their enemies; they use gold old-fashioned firearms. The game has been dubbed โPokรฉmon with Gunsโ for this very reason, and Nintendo sued Pocketpair over what it perceived as copyright infringement almost immediately after the gameโs release.

According to WindowsCentral, Nintendoโs ongoing legal battle against Palworldโs developer, Pocketpair, suffered a blow when the patent it claimed was infringed upon was rejected by the Japan Patent Office (JPO). The companies have been battling it out in the Tokyo District Court since 2024 over three patents. Nintendo claims damages, seeking 5 million yen (Around $33,000 USD) over the alleged infringement, and therein lies the problem. The JPO rejected one of the three patents for lack of inventive step. Thatโs patent jargon for a claim failing to prove obvious intention on the party at the time of filing. The JPO decision cited similar games, including ARK, Monster Hunter 4, and even Pokรฉmon GO as examples.
Nintendoโs Lawsuit Against Pocketpair Could Be Derailed

Patent law is complicated in every country, including Japan, and Nintendoโs three contested patents are intertwined in such a way that denying one could upset the entire case. The JPO issued a graphic showing just how intertwined the three patents are, and this presents a significant problem for Nintendo. According to Gamesfray, the denial is substantial and potentially insurmountable to Nintendoโs ability to argue that Pocketpair violated at least one of the three patents, since it clearly canโt have infringed on one of them. Nintendo could move to abandon its current effort and try to persuade the JPO with an amended claim, which could go its way, but only time will tell.
Nintendo is incredibly skilled at suing people and companies it perceives as infringing on its patents. This is the main reason why you donโt see many YouTubers doing walkthroughs of Nintendo games. They fear Nintendoโs mighty banhammer, and theyโre not the only ones. Palworld does several things better than Pokรฉmon, but it’s undeniable that they share some characteristics. Nintendo has to prove to a court that its patents give it the right to produce the only monster-capture games out there, and itโs having a hard time doing so. As the JPO pointed out, itโs not a unique mechanic to Nintendoโs games, suggesting thereโs not a lot of love for the company regarding this particular lawsuit.
Ultimately, only time will tell if Nintendo succeeds in its lawsuit against Pocketpair, but the company currently has the deck stacked against it. Thereโs a path forward for Nintendo, but given the low amount of damages it’s seeking, it could end up spending far more money than it gains. Meanwhile, Palworld remains available on multiple platforms, where a large number of fans enjoy it. Given the time it takes for these kinds of cases to work their way through the courts, it may be too late for Nintendo to do much about the competition, with a bigย Palworldย release set for 2026. That’s even if it does succeed in proving that Pocketpair infringed its patents.
