It’s not the mythical pinch-to-zoom patent, but the USPTO just granted a fairly broad Apple patent on capacitive multitouch displays. US Patent #7,663,607 describes a “transparent capacitive sensing medium configured to detect multiple touches” by way of two sandwiched layers of conductive lines hooked up to an appropriate circuit, and also covers a specific type of multitouch display with a similar two-layer capacitive sensor made of glass.
