The patents in question here, U.S. Patent Nos. 7,158,118, 7,262,760, 7,414,611 and 7,139,983, are so vague that the first three which cover 3D pointing devices could be applied to almost any 3 dimensional pointing object and the fourth one which covers the interface for displaying information on a television screen could cover any sort of GUI that uses a TV.
This is the problem with the US patent system at the present. Anyone can scribble an idea down on a piece of paper and send it in and then if someone actually ever does create it you can then sue them for all they have no matter how vague or flimsy the link between the two things are.
Also first post here on the Chartz woohoo finally stopped my lurking.
