Samsung and Apple said Wednesday they have agreed to end all patent lawsuits outside the U.S.
But Samsung said patent suits in the U.S. will continue.
The two companies have been locked in patent lawsuits in nine countries, including Korea, Germany and Japan, since April 2011. Both companies have spent hundreds of millions of dollars in legal fees.
In 2011 then Samsung Electronics CEO Choi Ji-sung said legal fees could reach US$200 million.
As a result, the two companies appear to have decided to settle their expensive overseas lawsuits and focus on the pending case in the U.S. They agreed that their resources should be focused on thwarting the onslaught of Chinese rivals Huawei, Lenovo and Xiaomi.
The latest decision has led to forecasts that Samsung and Apple may be able to reach a settlement in the U.S. case.
Apple has apparently asked Samsung to develop the application processors for its next-generation smartphones.
Further supporting such predictions, Samsung vice chairman Lee Jae-yong and Apple CEO Tim Cook were spotted chatting at a meeting of global corporate heavyweights in Sun Valley, Idaho last month.
Samsung has appealed a U.S. court ruling ordering the company to pay Apple $929 million for using Apple's patents without license in the Galaxy S and S2 smartphones. Apple recently withdrew its appeal.
A U.S. jury has also ordered Samsung to pay Apple $119.6 million for infringing the U.S. company's patents in the Galaxy S3 and Galaxy Note 2.
