Pay-Per-View Firm Seeks to Protect Fight Telecast: The company that is distributing the broadcast of the Dec. 7 middleweight championship fight between Sugar Ray Leonard and Roberto Duran filed suit Wednesday in U.S. District Court in Los Angeles to prevent bars and restaurants from broadcasting the fight without having paid the closed-circuit fee. The suit is designed to protect the salability of the broadcast, said Philip Deitch, attorney for Independent Entertainment Group Inc., a Colorado company that owns the closed circuit and pay-per-view television rights for Southern California, Hawaii, Minnesota, Iowa, Missouri and Kansas.
