Can Apple's Multi-Touch Patent Withstand Scrutiny -- or Challenge?
When the U.S. Patent and Trademark Office issued patent number 7,479,949 to "Jobs, et. al." for a "touch screen device, method, and graphical user interface for determining commands by applying heuristics," eyebrows shot up throughout the industry. At first glance, it seemed that Apple had locked down the concept of a multi-touch interface, posing problems for Palm and anyone else who might want to compete with the iPhone, iTouch, and future products. But some more careful consideration suggests that the patent may not be as broad as it seems -- and Apple may have missed including some seminal prior art, at least some of which was known to the inventors. That could cause spell problems in trying to enforce the patent.
