Fair Use is a legal doctrine in copyright law that permits limited use of copyrighted material without obtaining permission from the rights holders. It typically applies in situations such as criticism, commentary, news reporting, teaching, scholarship, or research. The determination of fair use depends on factors like the purpose of use, the nature of the copyrighted work, the amount used, and the effect on the market value of the original. Fair use aims to balance the rights of creators with the public interest in accessing and using information.
