How interesting. The story first hit 9-to-5 Mac, here's the link -
Slide to Unlock? Patented! | 9to5Mac | Apple Intelligence
Earlier, that story referenced patent
7,657,849 because it was filed in 2005 (but actually granted in Feb 2010.
Abstract:
A device with a touch-sensitive display may be unlocked via gestures performed on the touch-sensitive display. The device is unlocked if contact with the display corresponds to a predefined gesture for unlocking the device. The device displays one or more unlock images with respect to which the predefined gesture is to be performed in order to unlock the device. The performance of the predefined gesture with respect to the unlock image may include moving the unlock image to a predefined location and/or moving the unlock image along a predefined path. The device may also display visual cues of the predefined gesture on the touch screen to remind a user of the gesture.
But now 9-to-5 is correctly noting the 2004 Neonode N1m was cited by a Dutch judge who declared the Apple patent invalid due to this prior art -

(edit - try not to go nuts on tnkgrl from Engadget swapping her lefts and rights in the explanation - she was watching another display and goofed, it happens)
Meanwhile, they also updated the article to explain that it was patent
8,046,721 that was granted on Oct 25, 2011, interestingly filed in June 2009. Note the abstract -
A device with a touch-sensitive display may be unlocked via gestures performed on the touch-sensitive display. The device is unlocked if contact with the display corresponds to a predefined gesture for unlocking the device. The device displays one or more unlock images with respect to which the predefined gesture is to be performed in order to unlock the device. The performance of the predefined gesture with respect to the unlock image may include moving the unlock image to a predefined location and/or moving the unlock image along a predefined path. The device may also display visual cues of the predefined gesture on the touch screen to remind a user of the gesture.
So - the new patent filed in 2009 is a continuation (expansion?) of the patent filed in 2005.
I'm too busy or bored to track down iPhone details. There will be a lot of work for the legal hounds on this one. Five years on that first patent - that means that an examiner was not happy and Apple had to answer to their questions. That was probably the basis for the 2009 filing.
I was curious enough to see how wide this patent went on touchscreen tech and found -
The touch screen 126 and touch screen controller 122 may detect contact and any movement or break thereof using any of a plurality of touch sensitivity technologies, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with the touch screen 126.
If other courts agree with the Dutch judge, then Apple has tried to patent prior art and this all goes away.
If we get judges like that German idiot - well... it'll be more fun and games.
