A court in Tokyo has ruled that Samsung Electronics did not infringe on patents held by Apple.
The patent was related to transferring media content between devices. Apple is declining to comment, but must now pay the legal costs.
The South Korean company earlier lost a patent case in the United States and was ordered to pay more than $US1 billion in damages.
However, Tokyo District Judge Tamotsu Shoji on Saturday dismissed a case filed by Apple in August, finding that Samsung was not in violation of Apple patents related to synchronising music and video data between devices and servers.
On 24 August, a federal court in California court ruled Samsung had infringed Apple patents for mobile devices, including the iPhone and iPad.
The company said it will appeal against the US ruling.
A court in South Korea a few days earlier decided the two companies had infringed each other's patents.
Other cases are continuing in Europe and Australia.
