In the early 20th century, the Motion Picture Patents Company, or the Trust, was fought by the unlicensed independent films (dubbed "pirates" or "outlaws"), led by Laemmle. Others against the MPPC included Harry E. Aitken (Majestic Films), William Fox (founder of the Fox Film Corporation), and Adolph Zukor (Famous Players Film Company, a precursor to Paramount). The flexible, stealthy and adventurous independents avoided coercive MPPC restrictions (the requirement to use only Trust film stock and projectors, for example) by using unlicensed equipment, obtaining their own film materials, and making movies on the sly. After many of the independents, including IMP, organized their distribution subsidiaries into the Motion Picture Distributing and Sales Company in mid-1910, with Laemmle as their president, the Trust issued an injunction against Laemmle for the camera being used, claiming that it was an infringement on their patents,[3] but eventually lost.
Before long, the independents began moving to Southern California, and opened up a West Coast movie-making industry. In 1910, IMP began production in Los Angeles, and had a studio in Hollywood at Sunset Boulevard and Gower Street, which became known as "Gower Gulch" due to the actors dressed as cowboys and Indians waiting on that corner to be cast in Westerns.
By May 1912, the Motion Picture Distributing and Sales Company began to collapse, its supporting production companies removing their distribution needs to other companies or under their own direction. On June 10, 1912, the assets of Independent Moving Pictures were transferred to the newly incorporated Universal Film Manufacturing Company, which undertook to distribute for several of the departing Sales Company producers in continued opposition to the Edison trust. IMP was corporately dissolved but its name continued to be used as a brand name for Laemmle's productions.[4]
