However, a copyright does not grant a copyright owner absolute control over the copyrighted work. There are some limits to the control a copyright owner can exert over their work. One of the most commonly cited defenses to a copyright infringement claim is fair use. A fair use, under copyright law, is any copying of copyrighted material done for a limited and transformative purpose, such as to comment upon, criticize, or parody a copyrighted work. If a use of a copyrighted work is considered a fair use it can be done without permission from the copyright owner. Stated another way, if a use of a copyrighted work is considered a fair use, it would be considered copyright infringement.
