A judge has overturned a $625m (£383m) award against Apple - the biggest ever fine for patent infringement.
A jury had decided last year that the Spotlight, Cover Flow and Time Machine features on Apple computers infringed three patents belonging to technology firm Mirror World.
Texan federal judge Leonard Davis threw out the ruling saying that the jury had made a mistake and that Mirror Worlds had not provided enough evidence to support its complaint.
"Mirror Worlds may have painted an appealing picture for the jury, but it failed to lay a solid foundation sufficient to support important elements it was required to establish under the law," Judge Davis said.
Mirror Worlds sued Apple in 2008, arguing that it used its own patented software for archiving and displaying documents, including the 'card-flipping' technique used in scrolling through music in the iTunes library.
The jury awarded Mirror Worlds $208.5 million for each patent, or $625.5 million overall.
Apple then appealed the verdict, challenging the validity of the patents and arguing that they were not infringed.
Neither Apple not Mirror Worlds have commented on the new ruling.
