The patent in question, EP1964022, is written so broadly that Apple seems to feel it can be applied against any sort of unlock gesture on any screen. The German court didn’t follow Apple down quite that far – they ruled that Apple’s patent doesn’t apply to the unlock circle that was introduced with Honeycomb (and is currently employed on the Galaxy Nexus and several other phones).
It 's curious that Apple got this far on the slide to unlock patent – Apple’s patent is of very questionable veracity since prior art – the slide to unlock gesture of the Neonode N1m (see photo below) preceded Apple’s patent application, and in fact other German courts have indicated doubt about the patents validity.
While Motorola will naturally hope to find an appellate court of a similar mind, the appeal isn’t without risk to Motorola; while they will attempt to find a judge who might pay more attention to prior art, Apple will undoubtedly try to convince an appeals court that the circular Android unlock pattern should also constitute a violation of Apple’s intellectual property. Another Apple patent, one on sliding images in a photo gallery, was scheduled to be adjudicated today as well, but was postponed for a couple weeks.
It will be interesting to see how this plays out in the coming months.
