If those are the only 3 items they’re suing over, in an American court of law it’d be a slam dunk for PocketPair. Theres so much prior art, open use, and poor definitions involved the patents would be quickly invalidated.
But I’m not aware of the nuance of Japanese court, only that they tend to protect IP even more strongly than US courts.
Edit: fuck it, I haven’t been very interested so far, but I’m buying a copy of palworld today. Software patents are a broken system and Nintendo deserves every bit of fight given to them.
I went and bought several Pokemon-Like games after this whole debacle started. Made sure to get the physical versions, too.
They literally patented riding creatures lol they could sue fucking red dead redemption, it is complete insanity
Monster Hunter as well.
