Abstract: A system and method for users of copyrighted works to acquire after-the-fact clearances or rights from owners of protected works. Protected works include copyrighted works, such as musical works, literary works, movies, and the like. A computer-based electronic exchange collects and contains data on sellers and buyers of protected works, as well as historical usage data by buyers and users of a particular protected work. The system determines recommended bid and ask prices for the parties based on analysis of historical usage of various combinations of buyers and sellers for various protected works.
