Who ARE these guys? I've never heard of them, do they do any business or do they just sit around patenting controller ideas all day?
There are so many different patents in there it's hard to tell. As far as rumble technology goes, my impression was that Microsoft liscenced it's rumble from Immersion, and Nintendo nicked but legally modified Immersion's rumble concepts way back in the N64 days. As for the rest of the stuff, who knows? Maybe there's something there, but I doubt it.
Patent laws have gone crazy.
