Apple filed another lawsuit last year accusing Samsung's newer line of products of continuing to use technology controlled by Apple. Koh has scheduled trial in that case for early next year. She has implored both companies on several occasions to settle their difference with little success.
Apple filed its patent infringement lawsuit in April 2011 and engaged legions of the country's highest-paid patent lawyers to demand $2.5 billion from its top smartphone competitor. Samsung Electronics Co. fired back with its own lawsuit seeking $399 million.
The jury found that several Samsung products illegally used such Apple creations as the "bounce-back" feature when a user scrolls to an end image, and the ability to zoom text with a tap of a finger.
Samsung has mounted an aggressive post-trial attack on the verdict, raising a number of legal issues that allege the South Korean company was treated unfairly in a federal courtroom a dozen miles from Apple's Cupertino headquarters. Samsung alleges that some of Apple's patents shouldn't have been awarded in the first place and that the jury made mistakes in calculating the damage award.
Samsung has emerged as one of Apple's biggest rivals and has overtaken it as the leading smartphone maker. Samsung's Galaxy line of phones run on Android, a mobile operating system that Google Inc. has given out for free to Samsung and other phone makers.
Apple and Samsung have filed similar lawsuits in eight other countries, including South Korea, Germany, Japan, Italy, the Netherlands, Britain, France and Australia.
