Apple's 'slide to unlock' patent invalidated by German court
As part of an ongoing German patent struggle, Motorola on Thursday won a ruling from the country's Federal Patent Court, which said found all claims of Apple's "slide to unlock" user interface property invalid, though the decision can be appealed.
According to FOSS Patents' Florian Mueller, the parties affected by the ruling, Apple, Samsung and Google, all knew the Bundespatentgericht was likely to invalidate European Patent EP1964022 for "unlocking a device by performing gestures on an unlock image." The ruling came at the end of a day-long court session where Apple attempted to save the patent's validity by presenting 14 proposed claim amendments.
