To be clear: Nintendo did not apply for and does not possess a patent on the <em>general concept<\/em> of battling summoned monsters. Patents are intended to protect original, unique inventions that would be non-obvious for practitioners of the associated art. In other words, an invention isn&#8217;t patentable if it&#8217;s overly broad or similar to existing works.<\/p>\n<p>Even Nintendo&#8217;s terrifying legal apparatus can&#8217;t obtain a patent on an idea as broad as battling summoned characters. The concept of commanding creatures to fight would have been as unpatentable when Pok\u00e9mon first released in 1996 as it is today, because patents don&#8217;t protect concepts themselves. They protect clearly defined processes, designs, and applications. To meet that criteria, videogame patents like Nintendo&#8217;s &#8216;397 patent are\u2014by necessity\u2014limited in scope to <em>extremely <\/em>specific mechanical implementations.<\/p>\n<p>In Nintendo&#8217;s case, its &#8216;397 patent claims the invention of a unique, hyperspecific system of sub-character battling mechanics: one in which a movable player character can be directed with an input to summon a sub-character at a designated location, where it will either enter a battle mode if an enemy character is present or begin automatic movement, during which the player can perform a second input to cause the sub-character to move to <em>another<\/em> designated location where, if an enemy character is present, the sub-character will enter and complete an automated battle.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check >\n<div class='image-full-width-wrapper'>\n<div class='image-widthsetter' style=\"max-width:1920px;\">\n<p class=\"vanilla-image-block\" style=\"padding-top:56.25%;\"><img loading=\"lazy\" decoding=\"async\" id=\"k75qiqXfhmQG6dZshCN2ZA\" name=\"nintendo_patent_illust_2\" alt=\"Patent illustration from US patent 12,403,397\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2026\/04\/us-patent-office-revokes-nintendos-controversial-pokemon-battling-patent-in-nonfinal-decision-1.jpg\" mos=\"\" align=\"middle\" fullscreen=\"1\" width=\"1920\" height=\"1080\" attribution=\"\" endorsement=\"\" class=\"inline expandable\"><a href='https:\/\/arcader.org\/wp-content\/uploads\/2026\/04\/us-patent-office-revokes-nintendos-controversial-pokemon-battling-patent-in-nonfinal-decision-1.jpg' target='_blank' class='expand-button icon-expand-image icon' ><\/a><\/p>\n<\/div>\n<\/div><figcaption itemprop=\"caption description\" class=\" inline-layout\"><span class=\"credit\" itemprop=\"copyrightHolder\">(Image credit: Nintendo, USPTO)<\/span><\/figcaption><\/figure>\n<p>And that&#8217;s just how the claims are summarized in the patent abstract; <em>they get even more granular. <\/em>But as specific as those claims are, USPTO examiners are now saying the patent shouldn&#8217;t have been granted in the first place.<\/p>\n<p>Just weeks after Nintendo was granted the &#8216;397 patent, USPTO Director John A. Squires issued <a href=\"https:\/\/api.unifiedpatents.com\/reexam\/90020162\/MHJOOK9J168X179\" target=\"_blank\">an order for an ex parte reexamination<\/a> (EPR) of the patent, meaning a USPTO examiner would reevaluate whether the patent should have been granted to begin with. It was a noteworthy order, because unlike most EPRs that are initiated in response to requests from external parties, the &#8216;397 patent&#8217;s reexamination was ordered under the USPTO Director&#8217;s own initiative, indicating the case was now the subject of intensive USPTO scrutiny. (Better late than never, I suppose.)<\/p>\n<p>After reevaluating Nintendo&#8217;s claims in comparison with preexisting patents and videogames, <a href=\"https:\/\/api.unifiedpatents.com\/reexam\/90020162\/MN60O2K1X158X88\" target=\"_blank\">the USPTO examiner&#8217;s decision<\/a> rejected all 26 of the &#8216;397 patent&#8217;s claims, concluding that they bear too many similarities to prior art for the system they describe to be considered patentably non-obvious.<\/p>\n<figure class=\"van-image-figure inline-layout\" data-bordeaux-image-check >\n<div class='image-full-width-wrapper'>\n<div class='image-widthsetter' style=\"max-width:1920px;\">\n<p class=\"vanilla-image-block\" style=\"padding-top:56.25%;\"><img loading=\"lazy\" decoding=\"async\" id=\"ZEcEqmALbVDVHfLWRPq7ik\" name=\"nintendo_patent_illustration\" alt=\"Patent illustration from US patent 12,403,397\" src=\"https:\/\/arcader.org\/wp-content\/uploads\/2026\/04\/us-patent-office-revokes-nintendos-controversial-pokemon-battling-patent-in-nonfinal-decision-2.jpg\" mos=\"\" align=\"middle\" fullscreen=\"1\" width=\"1920\" height=\"1080\" attribution=\"\" endorsement=\"\" class=\"inline expandable\"><a href='https:\/\/arcader.org\/wp-content\/uploads\/2026\/04\/us-patent-office-revokes-nintendos-controversial-pokemon-battling-patent-in-nonfinal-decision-2.jpg' target='_blank' class='expand-button icon-expand-image icon' ><\/a><\/p>\n<\/div>\n<\/div><figcaption itemprop=\"caption description\" class=\" inline-layout\"><span class=\"credit\" itemprop=\"copyrightHolder\">(Image credit: Nintendo, USPTO)<\/span><\/figcaption><\/figure>\n<p>While the <a href=\"https:\/\/api.unifiedpatents.com\/reexam\/90020162\/MN60O2K4X158X88\" target=\"_blank\">list of references cited in the examiner&#8217;s decision<\/a> delightfully includes both World of Warcraft fan wiki pages and Reddit threads about RPG autobattle mechanics, the USPTO&#8217;s rejection relies primarily on a set of four preexisting videogame patent applications describing systems resembling those in the &#8216;397 patent. <a href=\"https:\/\/api.unifiedpatents.com\/reexam\/90020162\/MHPSD7KAX182X12\" target=\"_blank\">One of those patent applications<\/a> was filed by Konami, <a href=\"https:\/\/patentimages.storage.googleapis.com\/5f\/c0\/03\/65e6f8a4a9dbab\/US20200086216A1.pdf\" target=\"_blank\">another<\/a> by Bandai Namco; the remaining two, however, are <a href=\"https:\/\/patentimages.storage.googleapis.com\/b5\/e4\/72\/e6397585ccc8df\/US20220062760A1.pdf\" target=\"_blank\">Nintendo&#8217;s own<\/a> prior patent applications, <a href=\"https:\/\/api.unifiedpatents.com\/reexam\/90020162\/MHPSD7KJX182X12\" target=\"_blank\">one of which<\/a> features in all 26 arguments the examiner constructed to reject each of the &#8216;397 patent&#8217;s claims.<\/p>\n<p>As a US authority, the USPTO&#8217;s decision has no direct bearing on Nintendo&#8217;s Japanese patents or its ongoing Palworld lawsuit. Additionally, the USPTO&#8217;s decision is nonfinal, and Nintendo has two months to respond with its own counterargument\u2014a timeframe that can be extended at Nintendo&#8217;s request\u2014before the USPTO issues its final decision.<\/p>\n<p>And even if the USPTO ultimately decides to revoke the &#8216;397 patent, Nintendo can pursue an appeal with the Federal Circuit.
