I know very well that patents are used as a weapon, not to protect any property. There are a lot of things that are patented but for which no legal action has been taken because whoever infringes the patent is not seen as a threat by the patent rights holder, case Nintendo with Pokémon, who did not get serious about patents when Temtem or Cassette Besst or other Monster Cstchers came out, but when Palworld came out they got to work.

But that’s only if I USE the patented Mechanic, and why would I use willfully a patented mechanic? What benefits would get me to use a something that I know FOR SURE is going to get me in legal troubles?

It’s a pressure move, a way to flex legal muscle and intimidate. Nintendo’s real fear is that Palworld will start selling merchandise, which is where Nintengo earns more from pokemon. The patent thing is a deterrent so that the Palworld guys don’t get brave.

I know that, that’s why I’m asking where or how to know if I’m about to use a patented mechanic.

The Nemesis System of Middle-Earth: Shadow of Mordor and Shadow of War. Warner Bros. patented that mechanic and for that reason it has never been seen again in any game beyond those already mentioned. Nintendo also recently patented several mechanics of the Pokemon games in response to the growing popularity of Palworld. Bandai also patented the mechanics of placing mini-games on the loading screens, so for 20 years no game was able to do so until recently when the patent expired.

Lol I just received a follow request from an account just like the one you describe.
