As much as I don't like the idea of software patents, this is legitimate, but I'm not so certain that the patent should go to Apple.
Jeff Han, while doing research at NYU produced several multitouch prototype systems, demonstrating many of the gestures we all take for granted today. His company,
Perceptive Pixel produces multitouch products today. I'm not sure who shipped the first commercial product, but I'm nearly 100% certain that Han's research group was the first to invent the tech.
Apple deserves a lot of credit for making this tech small and cheap enough to cram into mass-market devices, but they didn't invent it.
