A federal appeals court on Wednesday rejected Motorola Mobility's attempt to hold several Asian suppliers liable under U.S. antitrust law for fixing prices of mobile phone displays sold to its foreign units. The 7th U.S. Circuit Court of Appeals in Chicago said Motorola Mobility, a unit of Lenovo Group, could not invoke U.S. antitrust law because its foreign subsidiaries had been the "immediate victims" of a conspiracy to boost prices on liquid crystal display screens.
