epa03754255 (FILE) A file photo dated 17 August 2011 shows a Samsung Galaxy Tab 10.1 (R) and an Apple Ipad2 (L) at a store in The Hague, The Netherlands. Samsung Electronics Co infringed on Apple Inc's patent for a visual feature on smartphones and tablet computers, the Tokyo District Court ruled 21 June 2013. Apple claimed that the South Korean electronic giant had infringed its patent on the way iPad and iPhone screens seem to bounce when users scroll to the end of an electronic file. The case was part of a four-continent intellectual property battle by the world's two largest smartphone makers for dominance of the lucrative markets. EPA/ROBERT VOS
