The Silicon Valley court battle between Apple and Samsung is entering its final phase.
Lawyers for both companies delivered closing arguments Tuesday before jurors started deliberating in a closely watched trial over the ownership of smartphone technology.
Each company accuses the other of stealing key features to develop some of the latest smartphones on the market, but Samsung's newest device, the Galaxy S5 released earlier this month, is not at issue.
The four men and four women on the jury are to determine which company is right and how much is owed in damages. Apple is demanding $2.2 billion after arguing that nine of Samsung's smartphones and one of its Galaxy tablets infringes five patents. Samsung Electronics seeks a fraction of that figure, some $6 million, saying Apple infringed two of its patents in creating the iPhone.
Testimony wrapped up on Monday with the recall of two expert witnesses to the stand to argue the effects of an appeals court ruling in an unrelated legal dispute between Apple and Motorola. The appeals court ruling upheld a trial judge's definition of an Apple "quick link" patent that automatically turns phone numbers and email addresses into links, enabling users to make calls and send messages with a single click.
Apple's expert, Carnegie Mellon professor Todd Mowry, argued the definition adopted by the appeals court made little difference in the case and that he believes Samsung still infringed Apple's patent for the "quick link" patent. Kevin Jeffay, a professor of computer science at the University of North Carolina and Samsung's expert, argued the opposite, saying the definition adopted by the appeals court supports Samsung's position that it didn't infringe Apple's patent.
In the end, U.S. District Judge Lucy Koh said the matter was best left for the jury to decide along with infringement questions of the other four patents.
