Nintendo’s Palworld Dispute – USPTO Orders Re-Examination of “Summon-and-Battle” Patent

In his decision, Squires explained that significant doubts about whether Nintendo’s new patent is truly innovative have emerged. He pointed to existing publications by Yabe and Taura, as well as older patents, which already detail the concept of a companion character assisting a player, either controlled by the game or by the player directly. This raises the question of whether Nintendo’s recently granted patent (filed in 2023, approved in September 2025) represents a genuine advancement in technology or simply repeats ideas already found in previous work.
