I assume Sony got a similar award for the PSP's square button.
In all seriousness, Nintendo has done a lot for the video game industry. Just about every one of their controllers introduced something new.
Game and Watch / NES = D-pad
SNES = shoulder buttons
N64 = analog stick
GameCube = "clicky" analog shoulder buttons
Wii = pointer, motion sensing
Virtual Boy = Dual D-pad

Select GameBoy cartridges = tilt sensing
Correct me if I am wrong, but Nintendo was the first to implement the above into a home gaming machine, or at least a mainstream one (e.g., there were various motion controlled gaming machines before the Wii, mainly dedicated sports simulations, but they don't really count a full-on gaming consoles).
