Palm has lost a lawsuit brought by Xerox, which owns a patent on "the computerised interpretation of handwriting". Xerox received a patent for what it calls Unistrokes after Palm had already started selling Pilot handhelds with its own Graffiti system. Xerox's general counsel Christina Claytontold the Washington Post: "Either Palm will have to cease production of its handheld organizer or license the technology from Xerox."
