U.S. Patent Office Boss Orders Reexamination of Nintendo’s Controversial ‘Summon Character and Let It Fight’ Pokémon Patent, Which IP Expert Claims ‘Further Undermines Credibility’ of Its Case Against Palworld
Title: U.S. Patent Office Director Calls for Review of Nintendo’s Disputed Pokémon Patent, Casting Doubt on Its Legal Strategy Against Palworld
The director of the United States Patent and Trademark Office (USPTO) has initiated a reexamination of Nintendo’s contentious patent concerning the mechanics of summoning characters to engage in battles, a decision that has drawn significant attention from intellectual property (IP) attorneys. This move comes in the wake of widespread criticism regarding the patent’s validity and its implications for the gaming industry.
In September, the awarding of Patent No. 12,403,397—referred to as the “397 patent”—to Nintendo sparked controversy among legal experts. Critics highlighted the problematic nature of the patent, which encompasses the fundamental aspects of battling mechanics in Pokémon games, where players summon Pokémon to fight one another with the aim of capturing them. Notably, similar gameplay mechanics exist in numerous other video games, including franchises like Persona, Digimon, and titles such as Elden Ring, raising questions about the patent’s originality and enforceability.
Florian Mueller, a well-known IP attorney, publicly expressed his disapproval of the patent on social media, stating that Nintendo “should never” have been granted such a patent. Kirk Sigmon, a video game patent lawyer, also voiced his concerns, commenting to PC Gamer that the claims presented in the patent were “not allowable” under current patent laws.
Recently, Games Fray reported that John A. Squires, a nominee of former President Donald Trump and the newly appointed director of the USPTO, has ordered a reevaluation of the patent after identifying “substantial new questions of patentability” related to certain claims within the patent. In his evaluation, Squires highlighted the claims that detail controlling player characters in a virtual environment, summoning sub characters for battles, and managing those battles either manually or automatically based on enemy presence.
Squires referenced two earlier patent applications—one by Konami dated 2002 and another by Nintendo in 2019—as critical “prior art” that could significantly influence the patentability of the claims in question. These acknowledgments suggest that the claims made by Nintendo may not meet the necessary criteria for patent protection, thus casting further doubt on the legitimacy of the ‘397 patent.
Mueller, in his commentary for Games Fray, suggested that the public backlash following the patent’s approval played a pivotal role in prompting Squires’ decision. He noted that while the reexamination does not equate to an outright revocation of the patent, it raises the likelihood that the USPTO may ultimately invalidate Nintendo’s claims. Nintendo now has a two-month window to respond to these developments.
The implications of this reexamination are significant for Nintendo and The Pokémon Company as they face off against Pocketpair in an ongoing legal dispute over the game Palworld. Mueller argues that this situation undermines the credibility of Nintendo’s patent claims against Pocketpair’s title, which is characterized by similar monster capture mechanics.
This recent turn of events adds to a series of setbacks for Nintendo in its legal confrontations with Palworld. Last month, one of the patents associated with Nintendo’s monster capture technology faced rejection from the Japan Patent Office (JPO), which cited a lack of originality as the reason. The JPO’s decision was supported by references to earlier games that utilized similar mechanics, such as ARK (2015), Monster Hunter 4 (2013), and Kantai Collection (2013). Ironically, games like Pocketpair’s Craftopia (2020) and Niantic’s Pokémon Go (2016) were also used as evidence to demonstrate the lack of novelty in Nintendo’s patent claims.
In summary, the ongoing legal struggle between Nintendo and Pocketpair illustrates the complexities of patent law in the gaming industry, particularly regarding the protection of game mechanics that may be seen as commonplace. As the USPTO reexamines Nintendo’s ‘397 patent in light of public concern and prior art, the outcome could significantly impact not only the current litigation but also the broader landscape of game development and intellectual property rights in the gaming sector.
