Xerox also obtained a US$22.5 million payment from Palm for retrospective licensing fees. In 2004, a judge ruled in favor of Palm on the patent review, saying Xerox's patent was not valid on the basis that "prior art references anticipate and render obvious the claim." Xerox appealed the ruling. An appeals court ruled in favor of Xerox with regard to the original ruling, that Palm had violated Xerox's patent, but sent the case back down to the lower court to decide whether the patent was valid to begin with. Palm later appealed the original court ruling both on the claim it violated Xerox's patent and as to the validity of the patent in the first place.

Joe Sipher and Ron Marianetti created more characters and punctuation and also designed a prototype of Graffiti that ran on a PC with a tablet peripheral. Other engineers at Palm revised and expanded the alphabet that Hawkins had created. Hawkins called this system "PowerPalmPrint" or P3. Hawkins also envisioned a single area for writing letters on top of each other. Hawkins recalled his insight: "And then it came to me in a flash. Hawkins believed that people would take the time to learn Graffiti just as people learn to touch-type. By using a simpler alphabet, computers could easily recognize handwriting. Graffiti was developed by Jeff Hawkins, who had previously created "PalmPrint" (the character recognition system used by the Casio Zoomer ) to recognize natural handwriting. These alternative strokes are frequently recognized with greater reliability. Two examples of these alternative strokes are the letters "V" (drawn the same only from right to left) and "X" (drawn the same as the letter "K" except reversed from right to left). Some letters can be drawn with strokes other than the "official" ones. "A" "F", "K" and "T" all are drawn without any need to match up a cross-stroke. Since the user typically cannot see the character as it is being drawn, complexities have been removed from four of the most difficult letters. The software is based primarily on a neography of upper-case characters that can be drawn blindly with a stylus on a touch-sensitive panel. Graffiti also runs on the Windows Mobile platform, where it is called "Block Recognizer", and on the Symbian UIQ platform as the default recognizer and was available for Casio's Zoomer PDA. as the recognition system for GEOS-based devices such as HP's OmniGo 100 and 120 or the Magic Cap-line and was available as an alternate recognition system for the Apple Newton MessagePad, when NewtonOS 1.0 could not recognize handwriting very well. Graffiti was originally written by Palm, Inc. Graffiti is an essentially single-stroke shorthand handwriting recognition system used in PDAs based on the Palm OS.
