Score one for Samsung in the company's long-running patent battles with Apple.

A Japanese high court upheld a lower court ruling that Samsung did not infringe on an Apple patent related to synchronizing music and video on Galaxy smartphones and tablets with servers, according to a report from Bloomberg.

The Intellectual Property High Court in Tokyo backed an August decision by Tokyo District Court that Samsung's mobile devices don't infringe on Apple technology. Following that ruling, Apple filed paperwork in October to appeal the decision.

Samsung gave us the following statement:

We welcome the court's decision, which reaffirmed our long-held position that our products do not infringe Apple's intellectual property. For decades, we have heavily invested in pioneering the development of technological innovations in the mobile industry, which have been constantly reflected in our products. We will continue to take all necessary measures to ensure the availability of our highly innovative products to consumers in Japan.

We've contacted Apple and will update the report when we have more information.

In the world of mobile, patents have become a key area of focus and an active battleground. Apple, Samsung, and other companies have sued each other repeatedly, accusing each other of ripping off designs and other elements. Apple won a big battle against Samsung last year, with a jury finding Samsung infringed on Apple patents and ordering it to pay Apple $1 billion. But Apple also has faced setbacks, such as the U.S. International Trade Commission ruling earlier in June that Apple infringes on a Samsung patent related to cellular technology.
