Nintendo has secured a U.S. patent for a summoning system in games, prompting debate over how far it reaches and whether it threatens Pokémon‑like mechanics—or not.
Here’s the TL;DR…
-
Nintendo’s U.S. patent (granted January 9, 2024) covers summoning a “sub‑character” to battle by throwing a ball, recently thrust back into the spotlight.
-
IP lawyers argue the claims are too specific to broadly affect games, though some see potential pressure on Pokémon‑style mechanics.
-
The news has ignited backlash, with fans worried it could chill innovation in summoning‑based titles.
The Patent Announcement
Games Fray reported that Nintendo was granted a patent for a system involving summoning characters to fight. The filing dates to 2021 and, after initial rejections, was ultimately approved in 2024. Nintendo and The Pokémon Company are listed as joint holders. Coverage notes the patent’s renewed attention in August 2025.
Details of the Patent
The documents describe moving a main character, summoning a “sub‑character” by throwing a ball at or near an enemy, and branching into combat. The sub‑character can battle automatically while still accepting player commands. Reports characterize it as closely mirroring a Pokémon‑style capture‑and‑battle loop. Some outlets mention the application faced numerous rejections before allowance and emphasize the narrow scope of what’s claimed.
Legal Opinions
According to coverage, IP lawyers consider the patent highly specific and question its enforceability against non‑identical systems. Commentary notes multiple claim rejections during prosecution and suggests the final approval is limited in scope. Some experts quoted by IGN argued Nintendo should not have received the patent at all, while others view it as a targeted protection rather than a sweeping ban on summoning mechanics.
Implications for Games
Reporting suggests the patent could deter blatant clones but is unlikely to disrupt established games, such as Digimon or Final Fantasy. Some outlets link it to ongoing concerns about Pokémon‑like titles, while others see it as a reminder of the power—and limits—of game‑mechanic patents. The overall consensus: narrowly tailored, potentially influential in edge cases, but not a broad clampdown.
