Apple rests case in second California patent trial against Samsung

Apple lawyers on Friday concluded their side of arguments in the latest spat with Samsung, bringing the initial phase of the company's case to a close after five days of court proceedings.

Last on the stand for Apple was economist Chris Vellturo, who was called upon to explain why Samsung's alleged patent infringement cost Apple nearly $2.2 billion in damages.

According to in-court reports from Re/code, Vellturo was grilled for more than hour by Samsung attorney John Quinn, who argued case documents showed the Korean company's rise to success in the smartphone industry had nothing to do with Apple's patents.

As noted by The Verge, Vellturo's royalty figures ranged from $1.61 to $15.03 per feature, per device. Combined, the resulting damages owed comes out to $40.10 per Samsung phone and tablet sold in the U.S.

Apple is asserting five patents in its case against Samsung, including a property covering the controversial "slide-to-unlock" feature and one for universal search.

With Apple's initial case presented, Samsung will now bring up its own expert witnesses in an attempt to prove features not found in Apple products are to thank for the company's success. In addition, the company looks to argue that Apple's five patents are insignificant and should not have been granted by the U.S. Patent and Trademark Office.

"You will not hear about one patent from one Samsung engineer," Apple's lawyer Bill Lee said in the company's opening statement. "They purchased them because they want you to believe that patents don't have much value. They want you to believe that patents aren't worth much."

If damages are owed, Samsung said during opening statements, it should not be on the level of $2.2 billion. The company frames the importance Apple puts on its patents as being a "gross exaggeration."

"This case is not about these five minor software features. It's not about them causing people not to by iPhones and instead samsung phones," said Quinn. "This is really about Apple versus Google/Android."
