Fair use is a doctrine in copyright law that allows limited use of copyrighted material without permission from the copyright holder for purposes such as commentary, criticism, news reporting, research, teaching, or parody. Fair use is a limitation and exception to the exclusive rights granted by copyright law to the author of a creative work. Copyright, on the other hand, grants the creator of an original work exclusive rights to its use and distribution. Therefore, fair use and copyright are related in that fair use is a concept within copyright law that allows limited use of copyrighted material under certain circumstances.
