Though it is worthing that Nintendo is alleging patent infringement, not copyright infringement. IANAL (I Am Not A Lawyer), but that doesn't sound like they're going after the models used in Palworld, but more overall mechanics?
Also, it was filed on May 2, 2024. Seems to me like there's millions of instances of prior art in that case.

That means that as long as you can sneak prior art past the patent examiner (fairly easy), you still get an effective business weapon.
Patents in gaming are weird and suck hard. They stifle innovation and growth. Games have evolved and grown on the backs of previous games forever.

Yuck. They may have just hired yakuzas lawyers (yakuzas use a lawyers a lot, and are experts in exploiting legal loopholes (and sometimes participating in the creation of them)).
That's a shame to put money into this disgusting mafia.
