Apple's touch-screen patentApple's touch-screen patentPosted Feb 2, 2009 22:22 UTC (Mon) by JoeBuck (subscriber, #2330)Parent article: Apple's touch-screen patent Mentor Graphics' schematic capture software used mouse gestures back in the early 1990s and perhaps before. SGI's also used them for a long time. It's true that these systems used one pointing device (no multitouch), but the Apple patent's claim you quote refers to "one or more" pointing device, and there seems to be plenty of prior art for the "one" case.
