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.
The Copyright Act of 1790 was the first federal copyright act to be instituted in the United States, though most of the states had passed various legislation securing copyrights in the years immediately following the Revolutionary War. The stated object of the act was the "encouragement of learning," and it achieved this by securing authors the "sole right and liberty of printing, reprinting, publishing and vending" the copies of their "maps, charts, and books" for a term of 14 years, with the right to renew for one additional 14-year term should the copyright holder still be alive.
A work of the United States government, is defined by the United States copyright law, as "a work prepared by an officer or employee of the United States Government as part of that person's official duties." Under section 105 of the Copyright Act of 1976, such works are not entitled to domestic copyright protection under U.S. law and are therefore in the public domain.
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.
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 Copyright Act of 1909 was a landmark statute in United States statutory copyright law. It went into effect on July 1, 1909. The 1909 Act was repealed and superseded by the Copyright Act of 1976, which went into effect on January 1, 1978; but some of 1909 Act's provisions continue to apply to copyrighted works created before 1978. It allowed for works to be copyrighted for a period of 28 years from the date of publication and extended the renewal term from 14 years to 28 years, for a maximum of 56 years.
In copyright law, a mechanical license is a license from the holder of a copyright of a composition or musical work, to another party to create a "cover song", reproduce, or sample a portion of the original composition. It applies to copyrighted work that is neither a free/open source item nor in the public domain.
The copyright symbol, or copyright sign, ©, is the symbol used in copyright notices for works other than sound recordings. The use of the symbol is described by the Universal Copyright Convention. The symbol is widely recognized but, under the Berne Convention, is no longer required in most nations to assert a new copyright.
The sound recording copyright symbol or phonogram symbol, ℗, is the copyright symbol used to provide notice of copyright in a sound recording (phonogram) embodied in a phonorecord. It was first introduced in the Rome Convention for the Protection of Performers, Producers of Phonograms and Broadcasting Organisations. The United States added it to its copyright law as part of its adherence to the Geneva Phonograms Convention in 17 U.S.C. § 402, the codification of the Copyright Act of 1976.
Droit de suite (French for "right to follow") or Artist's Resale Right (ARR) is a right granted to artists or their heirs, in some jurisdictions, to receive a fee on the resale of their works of art. This should be contrasted with policies such as the American first-sale doctrine, where artists do not have the right to control or profit from subsequent sales.
A copyfraud is a false copyright claim by an individual or institution with respect to content that is in the public domain. Such claims are unlawful, at least under US and Australian copyright law, because material that is not copyrighted is free for all to use, modify and reproduce. Copyfraud also includes overreaching claims by publishers, museums and others, as where a legitimate copyright owner knowingly, or with constructive knowledge, claims rights beyond what the law allows.
Sweat of the brow is an intellectual property law doctrine that is chiefly related to copyright law. According to this doctrine, an author gains rights through simple diligence during the creation of a work, such as a database, or a directory. Substantial creativity or "originality" is not required.
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.
Bridgeman Art Library v. Corel Corp., 36 F. Supp. 2d 191, was a decision by the United States District Court for the Southern District of New York, which ruled that exact photographic copies of public domain images could not be protected by copyright in the United States because the copies lack originality. Even though accurate reproductions might require a great deal of skill, experience and effort, the key element to determine whether a work is copyrightable under US law is originality.
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.
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.
Tax protesters in the United States advance a number of constitutional arguments asserting that the imposition, assessment and collection of the federal income tax violates the United States Constitution. These kinds of arguments, though related to, are distinguished from statutory and administrative arguments, which presuppose the constitutionality of the income tax, as well as from general conspiracy arguments, which are based upon the proposition that the three branches of the federal government are involved together in a deliberate, on-going campaign of deception for the purpose of defrauding individuals or entities of their wealth or profits. Although constitutional challenges to U.S. tax laws are frequently directed towards the validity and effect of the Sixteenth Amendment, assertions that the income tax violates various other provisions of the Constitution have been made as well.
F. W. Woolworth Co. v. Contemporary Arts, Inc. nicknamed The Cocker Spaniel Case, 344 U.S. 228 (1952), is a United States Supreme Court case regarding copyright infringement. The Copyright Act of 1909 allows recovery of either the profits of the infringing company or of the damages suffered by the copyright holder as the legal remedies. When the actual damages cannot be determined, statutory damages can be levied instead. At issue, is whether the trial judge can impose statutory damages when the actual profits of the infringer are known.
DeJonge and Co. v. Breuker & Kessler Co., 235 U.S. 33 (1914), was a United States Supreme Court case in which the Court held every instance of a copyrighted work must observe copyright notice formalities for the work to maintain copyright, even if the work appears multiple times on the same sheet of paper. Every copy of a copyrighted painting must bear the notice for the painting to maintain 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.
