Re: @ AC
Firstly: It's describing a concept that's been about for ages, just presumably not patented because no-one thought that the idea of using a pen to track movement is particularly novel. The tech /behind/ them may have been and would have been patented, but the general concept isn't.
Secondly: If they were serious about not using a Stylus in their designs then there'd be no risk to not attempting to patent it, especially with something like this that's existed for a good while. So they're now open to the concept of a stylus- so open that rather than doing it the sensible way where the pen is more or less a bit of plastic they're scrabbling to secure the IP for an inferior solution. This suggests not just a keenness to enter a market but a desperation to enter it.
