Re: Familiar 'gestures'...
Not sure about a Palm 1000 Graffiti cheat card, but from a quick google, that looks like a specific way of writing characters. Claim one of the Apple Patent (copied below) basically says a touch screen device which recognises the difference between a horizontal scroll, a screen translation, and a next gesture.
Infringement is easy (ok well not easy but not that hard), does whatever the potentially infringing thing is have all the features of the claim.
Validity is the reverse (almost), does the previous thing have all the features of the claim and if it doesn't are the thing that are not there obvious.
So, is this claim going to stand up? Don't have a clue but I'm not sure it is as flimsy as suggested.
1. A computing device, comprising: a touch screen display; one or more processors; memory; and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including: instructions for detecting one or more finger contacts with the touch screen display; instructions for applying one or more heuristics to the one or more finger contacts to determine a command for the device; and instructions for processing the command; wherein the one or more heuristics comprise: a vertical screen scrolling heuristic for determining that the one or more finger contacts correspond to a one-dimensional vertical screen scrolling command rather than a two-dimensional screen translation command based on an angle of initial movement of a finger contact with respect to the touch screen display; a two-dimensional screen translation heuristic for determining that the one or more finger contacts correspond to the two-dimensional screen translation command rather than the one-dimensional vertical screen scrolling command based on the angle of initial movement of the finger contact with respect to the touch screen display; and a next item heuristic for determining that the one or more finger contacts correspond to a command to transition from displaying a respective item in a set of items to displaying a next item in the set of items.
