Nokia files "Slide to unlock" Patent, ready to take legal action against Android?






Nokia has Finally patented its slide-to-unlock feature (similar to the revolutionary Nokia Bubbles).
we all know, Google and Android pulled a fast one and already patented something similar (expect more patent wars in the near future).
In Nokia's patent, they give a full description on how it works, for instance sliding the unlock icon while the phone is in idle mode and dropping it on an app to directly go to that app from idle mode.






Here is the full claim of Nokia's Slide-to-unlock patent:

1. A method comprising: providing a touch screen device in an idle mode; receiving an indication that an icon displayed on a screen of the device in the idle mode has been contacted and moved on the screen to reveal at least one application icon associated with an active/unlocked state of the device, wherein movement of the icon causes the icon to expand in size and to reveal the at least one application icon underlying an expanded form of the icon such that the expanded form of the icon and the at least one application icon are caused to be concurrently displayed on the touch screen device; and receiving an indication that the icon has been moved to an unlock region of the device to change a state of the device to an active/unlocked mode and activate an application associated with the revealed application icon.

2. The method of claim 1 wherein changing the state of the device further requires, after the icon has been moved to an unlock region of the device, activating an unlock function of the device.

3. The method of claim 2 further comprising expanding the size of the movable icon in a direction of movement of the contact with the movable icon.

4. The method of claim 1, further comprising, after the movable icon has been moved to reveal an application icon, temporarily illuminating the application icon and temporarily displaying at least one attribute associated with an application corresponding to the illuminated application icon, while the device remains in the idle mode.

5. The method of claim 4 wherein the at least one attribute is a function of the application.












 6. The method of claim 1, wherein the icon is positioned in a central area of the touch screen and wherein movement of the icon further comprises receiving an indication that an edge of the icon has been contacted and moved toward an edge of the touch screen, wherein an area of the icon expands toward the edge of the touch screen.






7. The method of claim 6, wherein the area of the icon expands proportionally in at least three directions.

8. The method of claim 6 further comprising the area encompassed by the expanded icon revealing an active/unlocked state of the device.

9. The method of claim 8 further comprising receiving a selection of an application revealed by the expanded icon to unlock the device and activate the application.

10. The method of claim 1 further comprising, providing, in the idle mode: at least one icon in a background area of the touch screen display, the at least one icon representing elements of an active/unlocked state of the device; and wherein the idle mode icon is configured to reveal, in a contrasting image, the elements in the background area, as the idle mode icon is expanded when contacted.

11. The method of claim 1 further comprising: receiving an indication that the icon has been selected; and causing a different application layer to be displayed in response to selection of the icon.

12. A method comprising: providing a touch screen device in an idle mode; contacting an icon displayed in a central area of a screen of the device in the idle mode and moving the icon on the screen to reveal at least one application icon associated with an active/unlocked state of the device, wherein moving the icon further comprises contacting an edge of the icon and moving toward an edge of the touch screen, wherein an area of the icon expands toward the edge of the touch screen; and moving the icon to an unlock region of the device to change a state of the device to an active/unlocked mode and activate an application associated with the revealed application icon.


13. The method of claim 12 further comprising selecting an application revealed by the expanded icon to unlock the device and activate the application.



It will be interesting to see what legal action (if any) Nokia will pursue against Android who filed for something very similar last year, just so you know Nokia filed for this patent way back in 2007. plus Apple already sued Motorola in Germany for using their own slide to unlock feature,
and though Android has implemented this feature in any of its devices, it is expected to be released with their next update.
