On Monday, Apple Inc.(NASDAQ:AAPL) appealed a ruling by a Tokyo court which held that Samsung Electronics did not violate a patent of Apple's relating to synchronising music and video servers.
Apple and Samsung, bitter rivals in the smartphone segment where they are struggling for dominance, are also at war over patents infringements and violations.
The Cupertino company's biggest grouse is that the Koran handset maker has been slavishly copying the designs of its iPhones and iPads and using it to build its Galaxy range of smartphones.
Incidentally before the launch of its Galaxy range, Samsung was a small player in the mobile handset market, catering mostly towards the entry-level and lower end of the consumer base. But the introduction of its Galaxy range changed all that and now it is the largest seller of smartphones in the world.
The Tokyo District Court had passed the ruling on August 31, according to court spokesman Yutaka Sakai. Along with the ruling favouring Samsung, Apple was also asked to pay up the cost of the lawsuit.
In August Apple had won a legal patents battle against Samsung in a San Jose federal court, with the jury holding the Korean company of having violated Apple' patents and ordered Samsung to pay Apple more than a billion dollars in damages.
Incidentally Apple is also seeking to reduce its dependence on Samsung, which is one of its component suppliers and derives as much as 4 percent of its revenues from supplying chips and displays to Apple.
According to reports Apple has now turned to Taiwan Semiconductor Manufacturing Company for its component requirements.
