"I've experienced firsthand the devastation to publishing, bookselling, and to local brick-and-mortar shopping that's resulted." Hagens Berman has a lengthy history of filing class-action suits alleging price-fixing. In 2011, the firm sued Apple, contending the tech giant was propping up e-book prices to the detriment of consumers. It launched another case against Amazon earlier this year leveling similar price-fixing allegations about the company's e-book division. Days before that suit was filed, authorities in Connecticut said they had also launched a probe into whether Amazon's deals to acquire e-books from publishers violate antitrust laws. Amazon is facing ongoing antitrust investigations by attorneys general in California, New York and Washington. Founder Jeff Bezos was grilled by the House antitrust subcommittee last year about Amazon's allegedly unfair practices against third-party vendors using its platform.
