Hagens Berman brought a class action alleging Amazon.com colluded with the “Big Five” publishers—Hachette, HarperCollins, Macmillan, Penguin and Simon & Schuster—to illegally fix e-book prices. The complaint asserts that in 2015 they agreed to raise e-book prices by up to 30% while shielding Amazon from competitive pricing, resulting in uniform online prices. It alleges antitrust and consumer-protection violations and seeks refunds for purchasers and an injunction to stop the alleged restraints.
