• Fair use is a legal concept based on section 107 of the Copyright Act that allows limited use of a copyrighted work for certain purposes (eg, criticism, commentary, news, education). Section 107 relies on four factors in assessing fair use: (1) the purpose and nature of the use, (2) the nature of the copyrighted work, (3) the extent and materiality of the portion used, and (4) the impact of the use on the potential market or value of the work, protected by copyright. Fair use is particularly relevant in relation to media professional liability, as use of copyrighted material beyond the scope of fair use may result in increased liability for the insured.
