Quote:

Patent #7,812,826 was first applied for on December 29, 2006, and over the course of the patent process the claims have been significantly narrowed to cover a very specific set of actions:
  1. A multitouch display detects at least two contacts.
  2. Those contacts perform a first gesture.
  3. That gesture adjusts an image in some way: magnification, orientation and rotation are specifically claimed, but the patent is broad enough to cover virtually any adjustment.
  4. The first set of contacts is broken.
  5. A second set of contacts is detected.
  6. The second contacts perform another gesture within a pre-determined period of time.
  7. The gesture continues to adjust the image in the same way.

  1. Well done US Patent Office, well done. It amazes me how a company is able to patent human gestures now. It seems to me what Apple is describing in their patent is a basic interaction that one would naturally have with a multi-touch display. There are some ridiculous patents being issued nowadays...

  2. Actually, this doesn't sound like a patent on the pinch zoom.

    It sounds like a patent on how to differentiate between two multitouch gestures made one after another.

    Bill Buxton has a nice history of multitouch gestures that shows pinch zooming going back at least to 1984.

    There's even an old-school video on YouTube there.

  3. "first applied for on December 29, 2006" I wonder if this may be an example of a submarine patent
