They had been warned in a related hearing at the same court earlier Thursday in front of Judge Paul Grewal that Koh "will not accept thousands of documents."

Apple sued Samsung last year for allegedly violating multiple patents and trademarks in Android-based smartphones and tablets. The lawsuit prompted Samsung to countersue, and the spat spilled over into a separate Apple suit against Samsung this year on products released after the first suit was filed.

The two sides are due to meet Koh again on Friday, June 29, at the court house, which is in San Jose.

Koh will hear arguments about a preliminary injunction Apple is seeking against Samsung's Galaxy Tab 10.1. Apple had in the U.S., but Koh put off a decision until an appeals court had ruled on a related issue. The court has since ruled, leaving Apple free to pursue the injunction.
