Goldin's success owed a great deal to presentation and promotion skills and a certain amount to his persistence in suing other magicians. The Keith theatre firm hired Goldin and took on six additional sets of performers to take versions of his show on tour around the United States. Among those performers was Servais Le Roy, a Belgian who was previously one of Goldin's rivals. Promotional stunts employed for the shows included ambulances outside the theatres and performers dressed as medics to give the impression there was a real risk of serious injury. Goldin was involved in many lawsuits during this phase of his career. There are suggestions that many of these cases were motivated by publicity as well as any genuine grounds for action. However he successfully used the courts to prevent competition from other magicians. In one case he managed to obtain an injunction against Selbit over the sawing illusion despite the fact that each man had a fundamentally different version of the trick and Selbit performed his first. In other cases Goldin took on the makers of films that exposed methods behind illusions. In "Goldin v. Clarion Photoplays" in New York in 1922 he initially lost because the judge said he had not proved he was the original inventor of the sawing illusion and the trick possibly dated back to ancient Egypt. However Goldin appealed and won with a ruling that stated he had "satisfactorily established that he is the originator of the illusion in question, which has achieved a great success under the title devised by him of Sawing a Woman in Half...and that his creation of the illusion has been so universally recognized that the title thereof is in the public mind associated with his own name"
