Samsung Electronics Co Ltd and Apple Inc said on Wednesday they had agreed to drop all patent litigation outside the US, scaling down a protracted legal battle between the smartphone rivals.

The iPhone and Galaxy handset makers issued nearly identical statements announcing the global ceasefire while vowing to pursue ongoing litigation in the US, which analysts say involves much bigger amounts of potential damages.

The South Korean and US tech giants declined to disclose the terms of the deal but said it did not involve "any licensing arrangements and the companies are continuing to pursue the existing cases in US courts."

The agreement ends patent disputes in Australia, France, Germany, Italy, Japan, the Netherlands, South Korea, Spain and the United Kingdom, countries where the smartphone market leaders had engaged armies of lawyers for what analysts said were questionable gains.

"Their fighting spirit has weakened and they now seek to focus on the key battleground, the US," said Young Park, a Hyundai Securities technology analyst in Hong Kong.

"They now see little need to wage a war around the world, which will only fatten the bills of lawyers," he said, adding the deal raised the possibility of a final licence agreement settling how the companies use each other's patented technologies.

Apple and Samsung together dominate the global smartphone market with a combined market share of 37.1% in the second quarter of 2014, according to Strategy Analytics.

Their legal battle began in the US in 2011 when Apple first filed a suit alleging Samsung "slavishly" copied elements of its iPhones, the device which launched the industry.

Days after the initial Apple suit was launched in the US, Samsung sued its Cupertino, California-based rival in South Korea, Japan and Germany, kicking off a series of tit-for-tat cases that spread around the world.

The litigation raged even as business flourished between the two technology companies, with Apple depending heavily on Samsung for components such as chips and liquid crystal displays.

An industry source familiar with the matter told Reuters the companies "decided that there was no merit in dragging on these lawsuits".

Nicholas Rodelli, an attorney and adviser to institutional investors for CFRA Research in Maryland, said there had been a "trend towards gradual de-escalation of patent hostilities between Apple and Samsung".

"It's not yet clear whether this is signal or noise, in terms of prospects for global settlement," he said.

On another front, Samsung is fighting Microsoft Corp over allegations it refused to make a royalty payment last year on patent licences after the US company announced plans to acquire Nokia's handset business.
