Unlike other companies who troll patents for stupid things, these guys actualy put out a wiimote without the nintendo logo on it a few years before nintendo. And from the sound of it it could do some things the wiimote cant. Like function in a 3d for example. Or point at things instead of only registering motion direction. However, this means the lawsuit is void, as nintendo didn't immitate these guys, but just made a huge d-pad that looks like the original product.
