Nintendo has secured a new patent that protects a common gameplay mechanic wherein an in-game character to summon another sub-character to support it in battle. As noted by Games Fray, the United States Patent and Trademark Office (USPTO) granted Nintendo patent number 12,403,397 on September 2, 2025. This is about summoning the “sub character” in a place where there already is another character that it will then (when instructed to do so) fight. This alternative scenario is about summoning the “sub character” at a position where there is no other character to fight immediately. This final step is about sending the “sub character” in a direction and then letting an automatic battle ensue with another character.
