A COURT has dismissed Apple Inc's claim that Samsung had infringed on its patent - the latest ruling in the global legal battle between the two technology titans over smartphones.

The Japanese court case addressed only the synchronising technology that allows media players to share data with personal computers and was not comparable in scope with the much larger victory that Apple won in the US last week.

South Korea's Samsung Electronics Co, the world's largest maker of phones, welcomed the Tokyo District Court ruling on Friday that its technology that allows media players and personal computers to share music files and other content did not infringe on Apple patents as confirming "our long-held position".

"We will continue to offer highly innovative products to consumers, and continue our contributions toward the mobile industry's development," the company said in a statement.

The Apple lawyer present at the courthouse declined comment and the company said later it had no comment, including whether it intended to appeal. In the past, Apple has accused Samsung of copying Apple products.

In a session lasting just a few minutes, Judge Tamotsu Shoji said he did not think Samsung products fell into the realm of Apple technology and dismissed the lawsuit, filed by Apple in August last year.

Apple, based at Cupertino in California and the maker of the hit iPhone and iPad, is embroiled in similar legal tussles around the world over whether Samsung smartphones, which rely on Google Inc's Android technology, illegally used Apple designs, ideas or technology.

In one such case, a jury in California ruled last week that Samsung products illegally used such Apple creations as the "bounce-back" feature when a user scrolls to an end image, and the ability to zoom text with a tap of a finger.

The jury awarded Apple $US1 billion ($A975.47 million) in damages, and a judge is now evaluating Apple's request to have eight Samsung products pulled from shelves and banned from the US market, including popular Galaxy model smartphones. Samsung's latest hit, Galaxy S3, was not part of the US ruling.

Friday's ruling was the first held in Japan in the Samsung-Apple global court battle, but other technology is being contested by the two companies in separate legal cases in Japan.

An analyst at Seoul-based Korea Investment & Securities, Seo Won-seok, said the Tokyo verdict showed that the lawsuits around the world are largely isolated and may not be affected by Apple's major victory in California.

"The favourable ruling for Samsung convinces me that lawsuits in other countries may play out differently from the one in the US," he said.

Apple products are extremely popular among Japanese consumers, but major Japanese carriers such as NTT DoCoMo sell Samsung smartphones as well. Japanese electronics maker Sony Corp also makes smartphones and tablet devices similar to Samsung's, using Android technology.

Samsung has sold more than 50 million Galaxy S and Galaxy S2 smartphones around the world. The legal battle also involves Samsung's Tab device, which Apple claims infringes on patents related to the iPad tablet.
