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. Unlike "fair dealing" rights that exist in most countries with a British legal history, the fair use right is a general exception that applies to all different kinds of uses with all types of works and turns 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.
Nichols v. Universal Pictures Corporation, 45 F.2d 119, was a United States Court of Appeals for the Second Circuit case on copyright infringement by non-literal copying of a dramatic work. The Court held that copyright protection cannot be extended to the characteristics of stock characters in a story, whether it be a book, play, or film.
Campbell v. Acuff-Rose Music, Inc., 510 U.S. 569 (1994), was a United States Supreme Court copyright law case that established that a commercial parody can qualify as fair use. This case established that the fact that money is made by a work does not make it impossible for fair use to apply; it is merely one of the components of a fair use analysis.
Computer Associates International, Inc. v. Altai, Inc., 982 F.2d 693 is a decision from the United States Court of Appeals for the Second Circuit that addressed to what extent non-literal elements of software are protected by copyright law. The court used and recommended a three-step process called the Abstraction-Filtration-Comparison test. The case was an appeal from the United States District Court for the Eastern District of New York in which the district court found that defendant Altai's OSCAR 3.4 computer program had infringed plaintiff Computer Associates' copyrighted computer program entitled CA-SCHEDULER. The district court also found that Altai's OSCAR 3.5 program was not substantially similar to a portion of CA-SCHEDULER 7.0 called SYSTEM ADAPTER, and thus denied relief as to OSCAR 3.5. Finally, the district court concluded that Computer Associates' state law trade secret misappropriation claim against Altai was preempted by the federal Copyright Act. The appeal was heard by Judges Frank Altimari, John Daniel Mahoney, and John M. Walker, Jr. The majority opinion was written by Judge Walker. Judge Altimari concurred in part and dissented in part. The Second Circuit affirmed the district court's ruling as to copyright infringement, but vacated and remanded its holding on trade secret preemption.
The Copyright, Designs and Patents Act 1988, also known as the CDPA, is an Act of the Parliament of the United Kingdom that received royal assent on 15 November 1988. It reformulates almost completely the statutory basis of copyright law in the United Kingdom, which had, until then, been governed by the Copyright Act 1956 (c. 74). It also creates an unregistered design right, and contains a number of modifications to the law of the United Kingdom on Registered Designs and patents.
In United States copyright law, transformative use or transformation is a type of fair use that builds on a copyrighted work in a different manner or for a different purpose from the original, and thus does not infringe its holder's copyright. Transformation is an important issue in deciding whether a use meets the first factor of the fair-use test, and is generally critical for determining whether a use is in fact fair, although no one factor is dispositive.
British Leyland Motor Corp. v Armstrong Patents Co. is a 1986 decision of the House of Lords concerning the doctrine of non-derogation from grants. This doctrine is comparable to, but somewhat broader than, the doctrine of legal estoppel, assignor estoppel, or estoppel by deed in U.S. law. Under the doctrine of non-derogation from grants, a seller of realty or goods is not permitted to take any action that would lessen the value to the buyer of the thing sold.
Substantial similarity, in US copyright law, is the standard used to determine whether a defendant has infringed the reproduction right of a copyright. The standard arises out of the recognition that the exclusive right to make copies of a work would be meaningless if copyright infringement were limited to making only exact and complete reproductions of a work. Many courts also use "substantial similarity" in place of "probative" or "striking similarity" to describe the level of similarity necessary to prove that copying has occurred. A number of tests have been devised by courts to determine substantial similarity. They may rely on expert or lay observation or both and may subjectively judge the feel of a work or critically analyze its elements.
Interlego AG v Tyco Industries Inc was a case in copyright law that originated in Hong Kong that eventually went before the Judicial Committee of the Privy Council in the United Kingdom.
Data East USA, Inc. v. Epyx, Inc. 862 F.2d 204, 9 U.S.P.Q.2d (BNA) 1322 was a court case between two video game manufacturers, where Data East claimed that their copyright in Karate Champ was infringed by World Karate Championship, a game created by Epyx. Data East released Karate Champ in arcades in 1984, and the game became a best-seller and pioneered the fighting game genre. The next year, Epyx published World Karate Championship for home computers, which sold 1.5 million copies. Data East sued Epyx, alleging that the game infringed on their copyright and trademark.
Stevens v Kabushiki Kaisha Sony Computer Entertainment, was a decision of the High Court of Australia concerning the "anti-circumvention" provisions of the Copyright Act 1968. The appellant, Stevens, had sold and installed modchips that circumvented the Sony PlayStation's copy protection mechanism. Sony argued that Stevens had knowingly sold or distributed a "circumvention device" which was capable of circumventing a "technological protection measure", contrary to s 116A of the Copyright Act.

Roth Greeting Cards v. United Card Co., 429 F.2d 1106, was a Ninth Circuit case involving the copyright of greeting cards that introduced the "total concept and feel" standard for determining substantial similarity. Courts used this test in later cases such as Reyher v. Children's Television Workshop (1976).
Nutt v. National Institute Inc. was an early case in which it was found that copyright extended beyond the words of a work. The court found that "The infringement need not be a complete or exact copy. Paraphrasing or copying with evasion is an infringement, even though there may be little or no conceivable identity between the two."
Authors Guild v. HathiTrust, 755 F.3d 87, is a United States copyright decision finding search and accessibility uses of digitized books to be fair use.
Hubbard v Vosper, [1972] 2 Q.B. 84, is a leading English copyright law case on the defence of fair dealing. The Church of Scientology sued a former member, Cyril Vosper, for copyright infringement due to the publication of a book, The Mind Benders, criticizing Scientology. The Church of Scientology alleged that the books contained material copied from books and documents written by L. Ron Hubbard, as well as containing confidential information pertaining to Scientology courses. Vosper successfully defended the claim under the fair dealing doctrine, with the Court of Appeal deciding unanimously in his favour. The judgment given by Lord Denning clarified the scope and content of the fair dealing defence.

Star Athletica, LLC v. Varsity Brands, Inc., 580 U.S. ___ (2017), was a U.S. Supreme Court case in which the court decided under what circumstances aesthetic elements of "useful articles" can be restricted by copyright law. The Court created a two-prong "separability" test, granting copyrightability based on separate identification and independent existence; the aesthetic elements must be identifiable as art if mentally separated from the article's practical use, and must qualify as copyrightable pictorial, graphic, or sculptural works if expressed in any medium.
