Apple claims that Samsung illegally copied technology from Apple’s iPhone and iPad tablet to some of Samsung’s Galaxy smartphones and the Galaxy Tab, and is seeking damages of 100 million Japanese yen. On October 15, 2012, Apple filed an appeal at the Intellectual Property High Court against the decision in the first trial made by the Tokyo District Court which ruled that Samsung does not infringe one of Apple’s patents.

What Apple is disputing is a single patent involving the synchronization of music and video data on devices with servers. Apple claims that Samsung illegally copied this patent technology for some of Samsung’s Galaxy smartphones and the Galaxy Tab, a total of eight products. NTT Docomo and KDDI handle the Galaxy series in Japan.

Apple claims that the patent technology focuses on the whole length of files when synchronizing with servers. In response, Samsung countered by stating that they use other methods for synchronization and that they do not infringe Apple’s patent.

The first trial decision was announced by the Tokyo District Court on August 31, 2012. The Chief Judge, Mr. Tamotsu Shoji, dismissed Apple’s claim, ruling that Samsung adopted different techniques from Apple’s.

The dispute began in April 2011 when Apple brought a lawsuit against Samsung to the U.S. courts. The legal fight has since expanded across the globe and the ruling in August 2012 is the first in a series of patent infringement cases being lodged by Apple in Japan. This decision will be reviewed by the Intellectual Property High Court since Apple has appealed against the decision in the first trial.
