Judge Lucy Koh has ruled that Samsung must now pay US$548 million from the first patent trial between Apple and Samsung has ordered by the Federal Court of Appeals.

Samsung, as expected, is appealing the decision based on a lengthy and ongoing patent invalidation process, saying that because of the US Patent and Trademark Office (USPTO) examination, the order isn’t being performed as required by federal procedure, notes MacNN (http://tinyurl.com/pqo4ow2).

This is all part of an ongoing, global legal battle. Apple and Samsung had filed more than 30 lawsuits against each other across four continents. For example, Apple alleges that Samsung copied the slide-to-unlock technology of its iPhone and iPad devices. On May 14, 2014, an U.S. appeals court affirmed a decision by the U.S. International Trade Commission (ITC) that Apple is innocent of violating three patents owned by Samsung. Earlier that month, a jury handed back a verdict in the latest Apple-Samsung legal battle over patent infringement.
