United Health Wins Temporary Court Order: A federal judge has temporarily barred United Healthcare Corp., a Minneapolis-based managed care firm, from marketing its health plan in Southern California. The order, issued by U.S. District Judge Dickran Tevrizian in Los Angeles, came after United Health Plan, an Inglewood-based HMO, sued its much-larger similarly named rival for trade-name infringement and unfair competition. United Health’s suit claims that United Healthcare’s recent marketing push in the region will confuse consumers and hurt its business. A United Healthcare spokesman said the company will appeal the judge’s ruling if it cannot resolve the dispute before Aug. 12, the date of the next court hearing.
