Summary

Fair use is a doctrine in United States law that permits limited use of copyrighted material without requiring permission from the copyright holder. It serves to balance the interests of copyright holders with the public's interest in wider distribution and use of creative works, acting as a defense against copyright infringement claims for certain uses. This doctrine, which originated in common law and was codified in the Copyright Act of 1976, is broader than similar rights in other common law countries and is based on a flexible test considering the purpose of the use, the amount used, and the market impact on the original work. Recent legal decisions, such as *Google LLC v. Oracle America, Inc.* in 2021, have continued to clarify and reaffirm the fair use doctrine, including its application in the context of AI copyright law, where it has been affirmed for training AI on legally acquired data.

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. It allows one to use and build upon prior works in a manner that does not unfairly deprive prior copyright owners of the right to control and benefit from their works. Together with other features of copyright law like the idea/expression dichotomy [...] Fair use is actually an affirmative defense to a claim of copyright infringement, meaning that the alleged infringer has the burden of proving their use was a fair use. It is now codified in Section 107 of the Copyright Act, which provides that fair use of a work “for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use, scholarship, or research)” is not an infringement of copyright. To determine whether a given use is fair use, the statute [...] The fair use test requires an assessment of all the factors together. The courts have repeatedly emphasized that there are no bright line rules, and that each case must be decided on its own facts. The factors often interact in the analysis. For example, the Supreme Court has stated that the more transformative the new work, the less will be the significance of other factors, like commercialism, that may weigh against a finding of fair use. The more transformative the use of the original work,

  • Measuring Fair Use: The Four Factors - Copyright Overview by Rich ...

    When you review fair use cases, you may find that they sometimes contradict one another or conflict with the rules expressed in this chapter. Fair use involves subjective judgments, often affected by factors such as a judge or jury’s personal sense of right or wrong. Despite the fact that the Supreme Court has indicated that offensiveness is not a fair use factor, you should be aware that a morally offended judge or jury may rationalize its decision against fair use. [...] Unfortunately, the only way to get a definitive answer on whether a particular use is a fair use is to have it resolved in federal court. Judges use four factors to resolve fair use disputes, as discussed in detail below. It’s important to understand that these factors are only guidelines that courts are free to adapt to particular situations on a case‑by‑case basis. In other words, a judge has a great deal of freedom when making a fair use determination, so the outcome in any given case can be [...] The less you take, the more likely that your copying will be excused as a fair use. However, even if you take a small portion of a work, your copying will not be a fair use if the portion taken is the “heart” of the work. In other words, you are more likely to run into problems if you take the most memorable aspect of a work. For example, it would probably not be a fair use to copy the opening guitar riff and the words “I can’t get no satisfaction” from the song “Satisfaction.”
