TOKYO (AP) — Apple Inc. has won a patent infringement lawsuit against Samsung Electronics Co. in a Japanese court, one of dozens of legal battles around the world between the technology giants.

The Tokyo District Court issued a partial verdict Friday in favor of Apple. Damages were not announced.

The court said in a summary that further examination is needed to determine if Samsung must pay compensation, and if so, how much. A final verdict is expected later.

Apple and Samsung are embroiled in similar battles in the U.S., South Korea, Germany, Italy, the Netherlands, Britain, France and Australia.

The latest was over “bounce-back” technology for scrolling on devices. Samsung was found to have infringed Apple’s patent on previous models of the Galaxy phone and tablet series. Samsung has since changed its smartphone design to show a blue light, instead of bouncing back.

The two companies are competing fiercely in global markets, and accuse each other of illegally using various technologies.

Samsung said it will study the ruling before deciding whether to appeal.
