A fair use is any copying of copyrighted material done for a limited and “transformative” purpose, such as to comment upon, criticize, or parody a copyrighted work. Such uses can be done without permission from the copyright owner. Fair use is a defense to copyright infringement. A copyright defendant that demonstrates to a court that their use of the copyrighted work is a fair use would not be liable for infringement. When a court is presented with a fair use defense the court will apply a test with several factors to the facts of the case to determine whether the defendant’s use constitutes a fair use.
