From the translation of the claims, they appear to describe Pokémon-style activities, with ‘191 focused on the act of throwing a ball at characters in a field, ‘117 tied to aiming, and ‘390 on riding characters.
If this is indeed the case, the lawsuit is clearly illegitimate (in the real sense, can't speak for legal nuances). Not surprising.
Seriously? Are they gonna go after TemTem. Coromon, Cassette Beasts, or any number of Pokémon clones for being too similar? The only thing i can see as a legitimate thing to sue on is if they find out palworld did use AI based off of Pokémon models to generate their models, but I think that was just a rumor anyway.
The difference between palworld on the ones you listed is Sony made a move to start a "Pokemon company"-like business with the Palworld devs (named Palworld Entertainment) and Nintendo feels threatened by the potential damages Palworld Entertainment would be able to cause being backed by Sony to the pokemon franchise.
