SAN FRANCISCO — The federal judge who oversaw Uber’s trade secrets trial showdown with driverless car rival Waymo has certified a class of Uber drivers in a separate case claiming the company takes an oversized chunk of the fees charged to passengers.

U.S. District Judge William Alsup of the Northern District of California, who called Waymo v. Uber “ancient history” during a hearing where the parties announced a settlement last week, issued an order Wednesday evening certifying a class in the driver suit, Dulberg v. Uber Technologies. Alsup’s class certification order currently remains under seal, but the judge publicly filed a notice of the factors he’ll take into account upon reviewing any proposed class settlement in the case.
