All I am willing to say is that my colleague and I made the suggestion to the Patent committee before we knew anything about the actual design of the iPhone (or even that there really was going to be one). In essence, we imagined what would be needed to enable a click-wheel to function for text and numeric input, and proposed a solution. We were surprised that the committee accepted the proposal - and, when we finally were disclosed on the iPhone, there was no click-wheel! But the patent was granted.
