EU Probing Whether Amazon Unfairly Copies Marketplace Products

European Union antitrust regulators are asking whether Inc. unfairly copies popular products sold by rivals on its online marketplace, according to a questionnaire sent to merchants. In a 16-page form to be filled out by Oct. 9, regulators want to know whether Amazon has in recent years started to sell products under its own brand that are "identical or very similar" to ones merchants have offered on the company’s website and what impact that’s had on their business.
