sharing aesthetic shouldn’t be enough to prosecute, especially in the case of patents.
My biggest defense against any claim like that is that they’re identifiably distinct. You put two of them side by side and not a single fan of either will be confused which is which.
any fan could tell the difference, but i can see parents being confused, and they’re the ones footing the bill for the vast majority of pokemon fans. pair that with the guns and back in the day if my parents caught wind of it, Pokémon would be banned in my household no matter how hard i tried to explain Palworld was different
for the record i am very anti-copyright and think Pokémon should be in the public domain by now, and generally hate Nintendo’s over-ligitous practices. i also don’t understand the patent angle of this action. but i ln this one specific case i can see where they’re coming from, as opposed to if they were going after good-faith tributes like Coromon or Cassette Beasts or a ROM hack
