The patent isn’t about the balls, it’s about the summoning controls, and it seems broad enough to cover any controls that use a control stick together with buttons to aim a device for summoning a character. It is ridiculously over-broad, and part of a grand tradition of software patents being granted that are more akin to patenting “the idea of doors” than “a specific design for a doorknob.”
That’s why the new control is “press button to summon next to you,” it doesn’t use the stick and thereby avoids the patent. It’s also ass because it doesn’t let you aim the summon, but it is hard to envision a control system for aiming summons that doesn’t use a stick and buttons and also doesn’t suck.
I thought our eyes worked by projecting some kind of energy beam that scanned objects, like how Superman’s X-ray vision is sometimes drawn.
