In 2014, a San Jose federal court issued a verdict that ordered Samsung to pay Apple $119.6 million for infringing three of Cupertino's patents. Samsung appealed that decision, and today, a U.S. appeals court overturned the ruling. The full text of the decision is available here.
The federal court had awarded Apple $98.7 million for infringement of a patent that "covers software to detect 'structures', such as a phone number, in text and to turn those structures into links." The appeals court ruled that "Apple failed to prove… that the accused Samsung products use an 'analyzer server' as we previously construed that term," and that Samsung therefore did not infringe the patent.
The other two patents in dispute—one that covers the iPhone's slide-to-unlock feature, and another that describes auto-correct software that automatically fixes typing errors on a phone—were both ruled invalid by the appeals court due to prior art.
The two mobility giants have been sparring over patents for some time now. A separate dispute between the two companies culminated in Samsung forking over $548 million in damages to Apple last December.
