Apple Inc.(NASDAQ:AAPL) has filed an appeal against a ruling by a Tokyo court which said that Samsung Electronics had not infringed on an Apple patent for a technology that allowed synchronising music and video data with servers.
The Tokyo District Court had issued the ruling on August 31 and had asked the iPhone maker to pay the costs of the lawsuit.
Apple and Samsung have sued each other over patent violations practically everywhere around the globe as both are battling for supremacy in the smartphone market that has been estimated by various reports at upwards of $200 billion.
Though they are bitter rivals in the marketplace, they are also partners, with Apple using chips made by Samsung, which gets about 4 percent in revenues from the supply of these products.
The Cupertino company has claimed that Samsung has blatantly copied the designs of its iPhones and iPads and used it to on its Galaxy range of phones, which are now the best-selling smartphones worldwide.
The companies are also trying to get each other's devices banned for sales in certin countries, especially in the United States, which is the biggest market for smartphones.
In August a San Jose federal court had awarded Apple more than a billion dollars in damages and held Samsung guilty of having violated Apple’s patents and also of having copied the designs of its mobile devices.
Samsung has appealed the ruling though Apple has sought a ban on the sales of the Korean company’s smartphones and tablets in the U.S.
