Germany's Federal Patent Court on Thursday invalidated all of Apple's claims for its slide-to-unlock patent. They death blow for Apple's slide to unlock patent was likely a Swedish phone called the Neonode N1m that launched well before the iPhone and featured its own slide to unlock implementation. The N1m was released in 2005 while Apple's own patent for slide to unlock wasn't filed until December of 2005.
