Exactly. But certain patents like you say shouldn't have been allotted in the first place - Rounded corners, Slide to unlock, and so on.. I'm reminded of this funny image that was trending on G+ recently: http://phandroid.s3.amazonaws.com/wp-content/uploads/2011/10...
Hah! That image is great. Oddly enough though, my initial reaction is to support Apple's claim for slide to unlock but scoff at them for "rounded corners." I'm not sure why, I guess because rounded corners seem so obvious while slide to unlock is pretty ingenious, if derivative.
Another patent war I can foresee (maybe in the future), that involves an obvious design conclusion is the Wheel hub motor (which is the future for most electric cars). Google for 'Protean Electric', these guys have patented an obvious design conclusion for a wheel hub motor. Something like Apple did.
