Samsung Galaxy S3
Tokyo District Judge Tamotsu Shoji ruled that Samsung did not violate Apple's patents concerning the synchronization of media and data files between devices. The ruling comes after Apple won its patent law suit against the South Korean tech giant in the USA last week, and was awarded damages of more than $1bn (£664m). Apple has since listed 8 Samsung products that it wants banned in the USA.
"We welcome the court's decision, which confirmed our long-held position that our products do not infringe on Apple's intellectual property," Samsung said in a statement. Apple, for its part, has declined to comment on the ruling.
The ruling doesn't mean Samsung's legal woes with Apple in Japan are over, however. Not only do Apple have 30 days to appeal the ruling, but this case is only the first in a raft of patent infringement cases being filed by Apple in the Japanese judicial system. Apple is also pursuing legal action against Samsung in around nine other countries including France, Germany and Australia.
