Patents are supposed to encourage innovation, right? So why is it that a Federal Appeals court just overturned a lower court’s decision to toss out Xerox’s claim against Palm over Graffiti (Palm’s alphabet for data-entry). Xerox PARC apparently patented any data-entry method that uses single-stroke characters. Nevermind obviousness — Xerox has never, ever developed a tool that uses this technology; they’re just using their patent to stop others from doing so. Link Discuss (Thanks, JimWICH)
