The Xerox patent was GRANTED in 97. They _developed_ Unistrokes BEFORE the first Pilot came out. Also, the patent is not quite as trivial as "single stroke" letters. Because the strokes are single letters, they can be superimposed in the same space, without ambiguity in recognition. Furthermore, the direction of the stroke can be used to assist the recognition algorithm. These were the ideas that were patented.
