Not sure how it works in Japan, but in many nations you have to file for a patent before or pretty soon after you release your product / service. In the US I think there's a 1 year grace period. It's a pretty common sense thing that stops whole businesses springing up and then being shut down by patent creation just like we are seeing here.

There are many games out there now that involve catching monsters and making them fight for you, Nintendo would be shutting down 100s, if not 1000s of developers if they wanted to go ahead with this and have it be taken seriously.

Anyone that has played Palworld will tell you that it much more resembles ARK than it does any Pokémon game or experience anyway.

My least favourite was my company motto of "Personal, Simple, Brilliant." It was supposed to be an ethos that ran through the whole company. It was actually just what management expected front line workers to be towards customers, regardless of whether the business leaders were making decisions to screw over the customer and the front line staff or not.

The amount of times I asked for support only to be shot down and laughed at when I told them "Well, that doesn't sound very personal, simple or brilliant to me." when speaking of their management culture.

Half of Pokémon are heavily inspired by artist's (who are not affiliated with Nintendo) illustrations of popular Yokai (Japanese mythological creatures). The rest are simply animals with very generic additions. "It's a cow but bipedal" "It's a kangaroo but with horns" "It's a pigeon but... actually yeah it's just a pigeon. No difference."

How can you copyright/patent that? It's hardly original.

I say this as someone who grew up loving Pokémon.
