US judge says Google must face some advertisers' antitrust claims, dismisses others

A U.S. judge on Friday ruled that Alphabet's Google must face advertisers' proposed class action lawsuit claiming that it monopolizes the ad exchange market, allowing a case to proceed.

But U.S. District Judge Kevin Castel dismissed some other antitrust claims, including those focused on ad buying tools used by large advertisers. (Reporting By Jon Stempel; editing by Peter Henderson and Leslie Adler)
