Pokemon is almost 30 years old. Patents expire because they are meant to promote innovation by giving inventors a competitive advantage over anyone who lurks about waiting for other people to do the R&D for them, and not stifle innovation by giving inventors a permanent veto over who gets to iterate on their invention. So a lawsuit on those grounds years after any such patent would have expired is clearly invalid.

Palworld came out in February.
The relevant patent was issued in May.
Nintendo has no case.
What if they had a lot of money and rabid fanboys instead?
