You can't get utility patents for "concepts". They patented a specific way to do pinch-to-zoom on mobile devices with capacitive touch screens (and interacting with an event loop). Which is a similar, but not identical, problem to doing multitouch pinch-to-zoom on a projector-based system as in the demo.
