Apple appealed a Tokyo ruling that said Samsung didn't infringe on the iPhone maker?s patent. According to an Aug. 31 ruling by Tokyo District Court, Samsung didn?t violate Apple?s invention of technology for synchronizing music and video data with servers.

Apple was ordered to pay costs of the lawsuit.

Samsung and Apple have been suing each other over patent-infringement claims on four continents for more than a year. In August, Apple won more than $1 billion in damages in a jury trial in San Jose, California.
