German Court Upholds 'Slide' Patent Ruling Against Apple

Apple Inc. patents covering the "slide to unlock" feature on smartphones are invalid, Germany's highest appeals court ruled, reaffirming a 2013 decision rejecting the U.S. company's claims by a lower court. The ruling by the Federal Court of Appeals in Karlsruhe covers one of the Apple iPhone's most popular defining features, of which makers of rival Android-based phones have developed their own versions.
