This time around, four patents were up in the air, as HTC took Apple to the UK High Court and, visa versa in a counter sue, in an attempt to invalidate European patents used as ammunition by Apple in a previous case in Germany. The four patents covered were for:
- Unlocking a device by performing a gesture on an image.
- A system to determine which elements of a screen were activated by single-finger touches; which were activated multi-finger touches and which ignored touches altogether.
- The use of a multilingual keyboard offering different alphabets on portable device, including mobile phones.
- Letting a user drag an image beyond its limits and then showing it bounce back into place to illustrate that they had reached its furthest edge.
