That isn't the patented technology. The algorithmn that is able to calculated the orientation of the paper that is scanned and re-orientate it (I have never scanned in a piece of paper exactly) is patented by another individual, but the Walking Papers guys either have explicit permission to use it or the owner allows non-commercial use.
