German Court Invalidates Apple's 'Slide to Unlock' Patent

In a legal victory for Google and Samsung, a German court has reportedly invalidated all patent claims related to Apple's "slide to unlock" user interface. The ruling by Bundespatentgericht, Germany's federal patent court, is a setback for Apple, which has pressed the patent against Google's Motorola and Samsung in courts across Europe in attempts to secure injunctions preventing the companies' devices from being sold.
