Judge Koh concluded the hearing by saying she would rule promptly on Apple's motion, without indicating when that ruling might take place, Samsung spokesman Kim Titus said.

Apple in April, citing a long list of instances in which the company allegedly copied Apple's hardware design, user interface and even packaging for its Google Android-based tablets. Among the tools Apple is seeking to use against Samsung are bans on importation of the devices.

Apple on Thursday that blocked the sale of Samsung's Galaxy Tab 10.1 while the company's suit against Samsung proceeds. It has also won a Galaxy Tab 10.1 ban in Germany, and in August a court in the Netherlands forced Samsung to prepare a software update to stop infringement of one patent. Samsung has retaliated with several suits against Apple in Europe.
