Pokemon "Summon" Patent To Be Reexamined Under New USPTO Boss' OrdersNintendo's litigation against Palworld developer Pocketpair is becoming increasingly complicated by the day, with one recent patent granted to the Pokemon franchise now under review by the United States. According to a new Games Fray report , the new head of the United States Patent and Trademark Office (USPTO), John A. Squires, has ordered a reexamination of Nintendo’s Patent No. 12,403,397 . Filed in January 2023, granted to Nintendo in September 2025, and dubbed the '397 patent, the listing is oftentimes oversimplified to "summoning characters and making them fight." It's for this reason that Squires's office is seeking to determine if such a feature is even patentable. "I have determined that substantial new questions of patentability have arisen as to claims 1, 13, 25, and 26 of U.S. Patent No. 12,403,397 B2 (the '397 patent')," Squires wrote in his order, citing two older applications filed by Konami in 2002 (Yabe) and Nintendo in 2019 (Taura) as justification for the patent's reexamination. "Thus, a reasonable examiner would consider each of Yabe and Taura to be important in deciding whether the claims are patentable, and Yabe and Taura each raise a substantial new question of patentability. I hereby order [the] reexamination of the '397 patent." Continue Reading at GameSpot

Nintendo Denied Japanese Patent For Pokemon-Like Capturing MechanicIn September, Nintendo was granted a US patent for "the fundamental gameplay mechanic of summoning a character and letting it fight another” within a video game. At the time, that was seen as an attempt to block any future Pokemon imitators like Palworld . Nintendo went out for another Pokemon-inspired patent in Japan, but the outcome wasn't in its favor this time. As reported by Video Games Chronicle , Nintendo filed a Japanese patent for a mechanic in a game that allows the player to throw an item that captures a character, like the Pokeballs in Pokemon. However, the application was denied because a third party submitted evidence from Ark, Craftopia, Monster Hunter 4 and more to prove that the mechanic isn't limited to Pokemon games and that it already exists. GamesFray first noticed the rejection, and added that it's plausible that the third party was Pocketpair, the developer behind Palworld. While that would make sense, it's conjecture for now. Pocketpair is still engaged in a legal battle with Nintendo over Palworld's alleged infringement on Nintendo's preexisting patents. That led Pocketpair to remove Pal Spheres and other features from Palworld that fell under the patents held by Nintendo. Continue Reading at GameSpot
