But no relationship has been more contentious than that between Apple and Samsung, the two largest makers of smartphones and tablets in the world, which share nearly all of the smartphone market's profits between them.

While the firms have filed more than a dozen intellectual property cases across Europe, Asia and North America, the decisions have failed to yield a clear advantage for either company - and have eaten up considerable resources just as the smartphone market has become more competitive.
Apple chief executive Tim Cook even said in a 2012 earnings call that he would "highly prefer to settle versus battle," though he would never stop defending Apple's intellectual property.
The latest announcement shows that "thermonuclear war" is not the only option anymore. But it doesn't mean that the fight is over. The statement made a clear exception that the firms are only dropping cases outside of the United States, the country where the highest-profile cases have taken place.
Apple won $930 million in damages from Samsung in a California court in 2012. It was also awarded $120 million in May in a US case against Samsung, although that was far less than Apple had asked for.
The companies have also failed to strike licensing settlements out of court - something that they've been urged to do multiple times by presiding judges - indicating this could be more of a pause in the fighting than a definitive end.
