Apple Inc. v. Samsung Electronics Co., Ltd. was the first of a series of ongoing lawsuits between Apple Inc. and Samsung Electronics regarding the design of smartphones and tablet computers; between them, the companies made more than half of smartphones sold worldwide as of July 2012. In the spring of 2011, Apple began litigating against Samsung in patent infringement suits, while Apple and Motorola Mobility were already engaged in a patent war on several fronts. Apple's multinational litigation over technology patents became known as part of the mobile device "smartphone patent wars": extensive litigation in fierce competition in the global market for consumer mobile communications. By August 2011, Apple and Samsung were litigating 19 ongoing cases in nine countries; by October, the legal disputes expanded to ten countries. By July 2012, the two companies were still embroiled in more than 50 lawsuits around the globe, with billions of dollars in damages claimed between them. While Apple won a ruling in its favor in the U.S., Samsung won rulings in South Korea, Japan, and the UK. On June 4, 2013, Samsung won a limited ban from the U.S. International Trade Commission on sales of certain Apple products after the commission found Apple had violated a Samsung patent, but this was vetoed by U.S. Trade Representative Michael Froman.
