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 that were part of the British Empire in the 20th century, 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.
Dastar Corp. v. Twentieth Century Fox Film Corp., 539 U.S. 23 (2003), was a copyright and trademark case of the Supreme Court of the United States involving the applicability of the Lanham Act to a work in the public domain.
Wheaton v. Peters, 33 U.S. 591 (1834), was the first United States Supreme Court ruling on copyright. The case upheld the power of Congress to make a grant of copyright protection subject to conditions and rejected the doctrine of a common law copyright in published works. The Court also declared that there could be no copyright in the Court's own judicial decisions.
Originality is the aspect of created or invented works that distinguish them from reproductions, clones, forgeries, or substantially derivative works. The modern idea of originality is according to some scholars tied to Romanticism, by a notion that is often called romantic originality. The validity of "originality" as an operational concept has been questioned. For example, there is no clear boundary between "derivative" and "inspired by" or "in the tradition of."
International News Service v. Associated Press, 248 U.S. 215 (1918), also known as INS v. AP or simply the INS case, is a 1918 decision of the United States Supreme Court that enunciated the misappropriation doctrine of federal intellectual property common law: a "quasi-property right" may be created against others by one's investment of effort and money in an intangible thing, such as information or a design. The doctrine is highly controversial and criticized by many legal scholars, but it has its supporters.
Secondary liability, or indirect infringement, arises when a party materially contributes to, facilitates, induces, or is otherwise responsible for directly infringing acts carried out by another party. The US has statutorily codified secondary liability rules for trademarks and patents, but for matters relating to copyright, this has solely been a product of case law developments. In other words, courts, rather than Congress, have been the primary developers of theories and policies concerning secondary liability.
Community for Creative Non-Violence v. Reid, 490 U.S. 730 (1989), is a US copyright law and labor law case of a United States Supreme Court case regarding ownership of copyright.
The threshold of originality is a concept in copyright law that is used to assess whether a particular work can be copyrighted. It is used to distinguish works that are sufficiently original to warrant copyright protection from those that are not. In this context, "originality" refers to "coming from someone as the originator/author", rather than "never having occurred or existed before".
The rule of the shorter term, also called the comparison of terms, is a provision in international copyright treaties. The provision allows that signatory countries can limit the duration of copyright they grant to foreign works under national treatment to no more than the copyright term granted in the country of origin of the work.

Feist Publications, Inc., v. Rural Telephone Service Co., 499 U.S. 340 (1991), was a landmark decision by the Supreme Court of the United States establishing that information alone without a minimum of original creativity cannot be protected by copyright. In the case appealed, Feist had copied information from Rural's telephone listings to include in its own, after Rural had refused to license the information. Rural sued for copyright infringement. The Court ruled that information contained in Rural's phone directory was not copyrightable and that therefore no infringement existed.
In copyright law, a derivative work is an expressive creation that includes major copyrightable elements of a first, previously created original work. The derivative work becomes a second, separate work independent in form from the first. The transformation, modification or adaptation of the work must be substantial and bear its author's personality sufficiently to be original and thus protected by copyright. Translations, cinematic adaptations and musical arrangements are common types of derivative works.
Sony Corp. of America v. Universal City Studios, Inc., 464 U.S. 417 (1984), also known as the "Betamax case", is a decision by the Supreme Court of the United States which ruled that the making of individual copies of complete television shows for purposes of time shifting does not constitute copyright infringement, but is fair use. The Court also ruled that the manufacturers of home video recording devices, such as Betamax or other VCRs, cannot be liable for contributory infringement. The case was a boon to the home video market, as it created a legal safe haven for the technology.
The copyright law of the United States grants monopoly protection for "original works of authorship". With the stated purpose to promote art and culture, copyright law assigns a set of exclusive rights to authors: to make and sell copies of their works, to create derivative works, and to perform or display their works publicly. These exclusive rights are subject to a time limit and generally expire 70 years after the author's death or 95 years after publication. In the United States, works published before January 1, 1928, are in the public domain.
Twentieth Century Music Corp v. Aiken, 422 U.S. 151 (1975), was an important decision of the United States Supreme Court, out of the Third Circuit, that questioned whether the reception of a copyrighted song on a radio broadcast constitutes a copyright violation if the copyright owner has only licensed the broadcaster to "perform the composition publicly for profit".
Folsom v. Marsh, 9. F.Cas. 342 is a 19th-century US copyright case, widely regarded as the first "fair use" case in the United States. The opinion was written by Judge Joseph Story, who set forth four factors that are in use today, and were ultimately codified in the Copyright Act of 1976 as 17 U.S.C. § 107.

Stevens v. Gladding, 58 U.S. 447 (1854), was a United States Supreme Court case in which the Court held the copyright of a work is not attached to the physical copperplate used to print the work, so purchasing the copperplate does not purchase the copyright.
Georgia v. Public.Resource.Org, Inc., No. 18-1150, 590 U.S. ___ (2020), is a United States Supreme Court case regarding "whether the government edicts doctrine extends to—and thus renders uncopyrightable—works that lack the force of law, such as the annotations in the Official Code of Georgia Annotated" (OCGA). On April 27, 2020, the Court ruled 5–4 that the OCGA cannot be copyrighted because the OCGA's annotations were "authored by an arm of the legislature in the course of its legislative duties"; thus the Court found that the annotations fall under the government edicts doctrine and are ineligible for copyright.
