NEW YORK ( TheStreet) -- A U.S. district judge has found Apple ( AAPL) guilty of colluding with book publishers to raise e-book prices, a violation of federal antitrust law. The U.S. Department of Justice alleged that Apple's conspiracy was intended to challenge Amazon.com's ( AMZN) dominance in the e-book market. Apple and book publishers allegedly colluded on ways to raise e-book prices above the $9.99 price tag Amazon often used. "Apple chose to join forces with the publisher defendants to raise e-book prices and equipped them with the means to do so," said U.S. District Judge Denise Cote in her decision. Cote said a new hearing will be scheduled to determine damages. Book publishers Hachette Book Group, Macmillan, HarperCollins Publishers, Penguin Group and Simon & Schuster all settled with the Department of Justice prior to the trial. An Apple spokesman said the company did not conspire to fix e-book pricing and will appeal the judge's decision.
