"Samsung makes fun of our damages claim. They make fun of us for asking for billions of dollars," he said. "The damages should be large because the infringement is massive."

Apple wants the jury to award it up to US$2.75 billion for lost sales and profits as a result of the alleged infringement. If the jury decides the infringement was deliberate and willful, the judge hearing the case could triple the award.

Samsung lawyer Charles Verhoeven began his closing statement by targeting Apple's design patent arguments. Apple failed to prove that any consumers had been confused by Samsung's design.

"The reason they didn't provide any evidence is because there is none," he said. Apple is "asking you to prevent its biggest competitor from giving consumers what they want -- smartphones with big screens."

"The real reason Apple is bringing this case is because rather than compete in the marketplace, Apple is seeking a competitive edge in the courtroom."
