San Francisco’s Joseph Saveri Law Firm, a specialist in antitrust class actions, has prevailed in a dispute with another plaintiffs firm over fees from a price fixing case that settled in 2013 for $163.5 million.

The U.S. Court of Appeals for the Fourth Circuit ruled in the Saveri firm’s favor on Monday, shooting down a bid by Miami’s Criden & Love for additional fees from an underlying antitrust case in Maryland federal court that accused titanium dioxide suppliers of fixing prices. The fee dispute began after a class settlement in the antitrust litigation that led to a $54 million award for plaintiffs lawyers involved in the case.
