SAN JOSE, CA—The blockbuster Apple-Samsung verdict ended last summer with a $1.05 billion jury verdict against Samsung. The panel found that the Korean electronics company infringed Apple patents and copyrights.

However, after hearing post-trial arguments, US District Judge Lucy Koh threw out a big part of Apple's win, slashing the damages figure by $450 million. Today, a retrial will begin in San Jose, focused solely on the issue of how much money Apple should get from Samsung.

More than 90 prospective jurors were just seated in the federal courtroom and sworn in. Koh just explained that the jurors are banned from reading about the case or communicating about the case until they are excused or until the trial ends.

After that, Koh asked the jurors if it would be a hardship for them to consider the case, which will last about one week and could have deliberations approaching the Thanksgiving holiday. About a dozen jurors raised their hands to ask to be excused for hardship.

The trial starting today affects older Samsung phones like the Fascinate, Galaxy S 4G, Galaxy S II Showcase, Mesmerize, and Vibrant. Another patent trial, based on Apple's and Samsung's newer products like the iPhone 5 and the Galaxy 4, is scheduled for March 2014.

In hearings leading up to the retrial, Koh said lawyers' arguments will be sharply limited and that new evidence can't be introduced. At one point, Koh referred to the retrial as "Groundhog Day."

Before the jurors came in, Koh made a final plea for the parties to talk settlement. "I would like to ask if there could be an additional attempt to resolve these cases," she said, telling attorneys it could be done on their time frame.

The lawyers agreed to set a mediation date. But for today, the worldwide patent war continues between these two companies dominating the smartphone market.
