Fair use is the right to use a copyrighted work under certain conditions without permission of the copyright owner. The doctrine helps prevent a rigid application of copyright law that would stifle the very creativity the law is designed to foster. It allows for the unlicensed (that is, without permission or payment of royalty) use of a copyrighted work where the balance of several factors weighs in favor of such use. Four of these factors are specifically enumerated in the statute. Application of fair use requires a factual analysis of these four factors as applied to the facts of the proposed use.
