This time, the process for calculating the amount Samsung owed was simpler than in the previous trial. The jurors had to fill out a one-page form assessing the damages for each infringed patent, unlike last time, when jurors filled out a complex 20-page form.

Still, the new jury appeared to have some trouble crunching the numbers, taking parts of three days to reach a conclusion. On Wednesday afternoon, the judge called a meeting to answer questions from the jury about how to decide whether Apple was entitled to lost profit, and if so, how to calculate it.

Apple’s lawyer, Harold J. McElhinny, showed an internal Samsung document to highlight that employees had acknowledged that the battle in the mobile industry was a “two-horse race” between Apple and Samsung. Therefore, he said, many sales made to Samsung most likely could have gone to Apple.

Samsung, however, said that it should pay a much smaller amount in the form of royalties for each device it sold that carried the infringing features. Its lawyer, Bill Price, said that Apple was not entitled to lost profits because people had bought Samsung phones for reasons unrelated to the features covered by patents, like the fact that some Samsung phones had bigger screens and that Samsung’s phones and tablets were generally cheaper than Apple’s.

Also on Wednesday, Samsung tried to delay the entire trial. The company argued that a patent involved in the trial, which covered touch-screen mechanics, might be deemed invalid by the United States Patent and Trademark Office. In light of that, reaching a verdict now would be wasteful, Samsung said.

But Apple said in a response late Wednesday that Samsung’s motion to delay the trial had “crossed the bounds of reason.”

Apple and Samsung continue to fight in courts around the world. In the United States, the tide has shifted in Apple’s favor. Both companies persuaded the United States International Trade Commission that the other had violated patents, resulting in bans on each other’s products. The Obama administration ultimately vetoed the ban on Apple products, while upholding the ban on Samsung products.

The two companies are scheduled for another trial in March 2014. That trial will involve a different set of Apple patents and some newer products, including Samsung’s popular Galaxy S III — a smartphone that at one point surpassed the iPhone in sales. Judge Koh is expected to also oversee that case.
