Imagine if you had a hammer and decided to use it to hit a nail and then someone came along and said “I see you’re using my method to build a house! Pay up!”
Well, you can’t patent something like that!
Imagine you open up a game engine, any engine, and decide you need to point to an objective so you decide to use an arrow. A game company says “You’re using our method to identify objectives! Pay up!” and that one is a unique mechanic?
How long has humanity been using arrows to point to things? How can you patent it just because it’s a digital arrow?
The ludicrousness is the point. “Capture a creature in a ball”… How close is that to Red Dead’s lasso? Could Nintendo patent capturing a creature with a rope? Does anyone hold that patent yet? No, it would be silly to try to patent something like that - yet at one point I’m certain it was someone’s “technique” while everyone else was jumping on the horses back like Breath of the Wild.
