Summary

Fair Use is a doctrine in United States copyright law that permits limited use of copyrighted material without requiring permission from the copyright holder. It aims to balance the interests of copyright holders with the public's interest in wider distribution and use of creative works, serving as a defense against copyright infringement claims. Originating in common law during the 18th and 19th centuries to prevent copyright law from stifling creativity, the doctrine was codified in the Copyright Act of 1976 and has been clarified by U.S. Supreme Court decisions, including the 2021 case *Google LLC v. Oracle America, Inc.* The U.S. fair use doctrine is generally broader than 'fair dealing' rights found in other English Common Law countries, employing a flexible test that considers the purpose of the use, the amount used, and the impact on the original work's market. Recent legal discussions, such as the ruling against fair use in the *Thompson Reuters vs. Ross* lawsuit, highlight its critical role and potential precedent-setting impact on other AI copyright cases, like the one between *The New York Times* and OpenAI.

Fair use

Fair use is a doctrine in United States law that permits limited use of copyrighted material without having to first acquire permission from the copyright holder. Fair use is one of the limitations to copyright intended to balance the interests of copyright holders with the public interest in the wider distribution and use of creative works by allowing as a defense to copyright infringement claims certain limited uses that might otherwise be considered infringement. The U.S. "fair use doctrine" is generally broader than the "fair dealing" rights known in most countries that inherited English Common Law. The fair use right is a general exception that applies to all different kinds of uses with all types of works. In the U.S., fair use right/exception is based on a flexible proportionality test that examines the purpose of the use, the amount used, and the impact on the market of the original work. The doctrine of "fair use" originated in common law during the 18th and 19th centuries as a way of preventing copyright law from being too rigidly applied and "stifling the very creativity which [copyright] law is designed to foster." Though originally a common law doctrine, it was enshrined in statutory law when the U.S. Congress passed the Copyright Act of 1976. The U.S. Supreme Court has issued several major decisions clarifying and reaffirming the fair use doctrine since the 1980s, the most recent being in the 2021 decision Google LLC v. Oracle America, Inc.

    Fair use is the right to use a copyrighted work under certain conditions without permission of the copyright owner. The doctrine helps prevent a rigid application of copyright law that would stifle the very creativity the law is designed to foster.

To determine whether a given use is fair use, the statute [...] Use that adversely affects the market for the copyrighted work is less likely to be a fair use. This ties back to the first factor, and the question whether the putative fair use supplants or substitutes for the copyrighted work. If a use results in lost sales to the copyright owner (or could, if the type of use became widespread), that will weigh against fair use.

We conclude that because 17 U.S.C. §107 created a type of non-infringing use, fair use is "authorized by the law" and a copyright holder must consider the existence of fair use before sending a takedown notification under §512(c)."

However, even if a person determines a use to be a “fair use” under the factors of section 107 of the Copyright Act, a copy shop or other third party need not accept the person’s assertion that the use is noninfringing. Ultimately, only a federal court can determine whether a particular use is, in fact, a fair use under the
