"Sustainable advantage"

Denison said Samsung's strategy is to gain "a sustainable advantage" in the market using core competencies that its rivals don't have. If Samsung copied rivals products, "that would not represent a sustainable advantage," Denison said.

The dueling lawyers and Judge Koh also continued to wrestle over the large volume of objections and motions for reconsideration coming from both sides in the case. Early in the day, Koh had the companies to deliver all their objections in front of the jury, using up the time they have allotted for arguing their cases. In a conference following Friday's testimony, Koh said she would allow lawyers to submit two objections per witness on paper.

The case is 11-01846, Apple v. Samsung Electronics, in the U.S. District Court for the Northern District of California.
