Yepp, if they were attempting anything grand they’d have filed by now. The worst they could bring from this point is maybe infringement on a Pal by Pal basis but even there I feel there’s not much to go on given that Pokemon draws so heavily from the real world and you can’t really claim a concept like “volcano turtle mashup” as something so uniquely creative that it deserves copyright on the concept level. Same goes for just about all Pokemon with maybe some exceptions. So while Palworld absolutely has stuff like “electric dog” and others which overlap that is not enough.
