@Jens_Rasmussen @LukeAlmighty @Mr_NutterButter you can patent the nemesis system because there is an actual.. system, within software, that they designed.
not saying it's right, but they can, and did, do that. patents last 20 years btw (max).
you can't patent throwing a ball. it'd have to be a device throwing the ball, or the ball itself because of it being a new thing.
