USPTO has rejected Nintendo’s summon character and let it fight Pokemon patent The extremely controversial patent that Nintendo successfully patented for the Pokemon franchise then was reexamined after discourse online has now been rejected by the USPTO. The patent was for summoning a character and letting it fight for you, a formula that's been used in video games for years. It should be stated that IGN says that this is a non-final ruling and presumably Nintendo can argue against it. This is all being used in the case against Palworld in Japan and as pointed out patents are at the heart of the lawsuit. https://mynintendonews.com/2026/04/01/uspto-has-rejected-nintendos-summon-character-and-let-it-fight-pokemon-patent/
