In a stunning ruling, the Federal Circuit has reversed a lower court and remanded a case for trial on Xerox's claim of patent infringement relating to Palm's handwriting recognition technology.
The patent covers "Unistroke" software developed by Xerox. The technique recognizes one stroke motions as characters. Xerox contended in the court below that the Palm Graffiti handwriting recognition system infringes the patent. Palm filed a motion for summary judgment, and the district court agreed that the Palm system did not infringe.
This morning the Federal Circuit reversed the district court's grant of summary judgment in Palm's favor, setting the stage for a trial on the issue of infringement.
