Copyright law of the United States

• 1. Introduction

  ›

  Copyright law of the United States rests on a constitutional promise made by the Founding Fathers: that creators deserve exclusive control over their work, but only for a limited time. The original bargain, set by the Copyright Act of 1790, gave authors just 14 years of protection, with one chance to renew for another 14. That was the deal. Two centuries later, that window had stretched to the life of the author plus 70 years. How a modest legal instrument grew into one of the most contested frameworks in American life is a story that runs from the printing presses of colonial America all the way to cheerleader uniforms, Beatles songs, and the ghost recordings of musicians who died before the digital age. What counts as an original idea? Who truly owns a song, a software program, or a photograph? And when does the public finally get to use what its creators have left behind?

• 2. The Constitutional Root

  ›

  Article I, Section 8, Clause 8 of the U.S. Constitution hands Congress the power "to promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries." This Copyright Clause is the foundation on which every subsequent law was built. It was not designed as a gift to creators alone. The goal was social: incentivize creation, then release work to the public so the whole country could benefit. As with many legal doctrines, whether copyright law actually achieves that purpose remains a matter of genuine debate among scholars and courts alike.

  The British Statute of Anne directly influenced the first federal copyright act of 1790. That original law set the 14-year term with one renewal. The Copyright Act of 1831 pushed the initial term out to 28 years. Then the Copyright Act of 1976 reshaped everything, extending protection to the life of the author plus 50 years, or 75 years after publication for works made for hire. The 1976 Act also codified the law in Title 17 of the United States Code, the section of federal law where copyright still lives today.

• 3. The Mickey Mouse Extension

  ›

  By 1998, the copyright term stretched again, this time through the Sonny Bono Copyright Term Extension Act. Critics quickly nicknamed it the "Mickey Mouse Protection Act," because one of its most visible effects was preventing the Disney cartoon character from slipping into the public domain. Under the new law, protection ran for the life of the author plus 70 years. For works made for hire, the term became 95 years after publication or 120 years after creation, whichever arrived first. Senator Josh Hawley introduced the Copyright Clause Restoration Act of 2022, which proposed rolling those terms back to 28 years with a single renewal option, for a maximum of 56 total years. He noted those were the same terms that had been in place from 1909 until 1976. A similar bill appeared again in 2023, but neither has yet become law.

  The practical consequence of these extensions shows up most clearly in sound recordings. Before 1972, recordings were not covered by federal copyright at all. They were governed by a patchwork of state laws, some with no expiration date. The Sound Recording Amendment of 1971 brought recordings fixed on or after the 15th of February 1972 under federal protection. Everything older stayed under state law. That left a situation where older recordings could, in theory, stay protected indefinitely at the state level, making public domain audio virtually nonexistent.

• 4. Music Modernization and Old Recordings

  ›

  The Music Modernization Act of 2018 resolved the decades-long tangle over pre-1972 recordings. For the first time, federal copyright reached back to cover all sound recordings regardless of when they were made, and state copyright laws on those recordings were preempted. The first recordings to enter the public domain under the new framework were those fixed before 1923, which crossed the threshold on the 1st of January 2022. Recordings made between 1923 and the 14th of February 1972 will phase into the public domain over the following decades on a staggered schedule: works fixed between 1923 and 1946 become public domain after 100 years, while works fixed between 1947 and 1956 receive 110 years. Recordings fixed between the 1st of January 1957 and the 14th of February 1972 will all enter the public domain together on the 15th of February 2067.

  An earlier dispute had tested this territory from a different angle. In May 2016, Judge Percy Anderson ruled in a lawsuit between ABS Entertainment and CBS Radio that digitally remastered versions of pre-1972 recordings could receive their own federal copyright, because of the creative effort involved in remastering. The Ninth Circuit appeals court later reversed that decision, siding with ABS Entertainment.

• 5. Ideas vs. Expression

  ›

  One of the most fundamental principles in copyright law is also one of the hardest to apply in practice: copyright protects the expression of an idea but never the idea itself. The Copyright Act of 1976 states this plainly, ruling that no protection extends to "any idea, procedure, process, system, method of operation, concept, principle, or discovery." So a paper arguing a political theory is protected; the theory itself is not. A second author is free to describe the same theory in entirely different words without any infringement.

  Judge Learned Hand captured the difficulty with characteristic directness: "Obviously, no principle can be stated as to when an imitator has gone beyond copying the 'idea,' and has borrowed its 'expression.' Decisions must therefore inevitably be ad hoc." The line shifts depending on the work and the court. Facts are similarly off-limits. The Supreme Court made this explicit in Feist Publications, Inc. v. Rural Telephone Service Co., where it rejected copyright protection for a white-pages phone book. Alphabetizing telephone numbers requires no creativity, and the court rejected what was called the "sweat of the brow" doctrine: the idea that sheer effort alone could earn copyright. Hard work, without a creative spark, does not cross the threshold.

• 6. Useful Articles and Cheerleader Uniforms

  ›

  Star Athletica, LLC v. Varsity Brands, Inc. began as a dispute over cheerleader uniform designs. Varsity Brands sued Star Athletica for copying five of its designs, and in 2017 the U.S. Supreme Court used the case to set a new test for when visual elements on useful articles qualify for copyright. The court held that such features are eligible "only if the feature (1) can be perceived as a two- or three-dimensional work of art separate from the useful article and (2) would qualify as a protectable pictorial, graphic, or sculptural work" if imagined apart from the article. Applying that test to the uniforms, the court found that the arrangements of colors, shapes, stripes, and chevrons could be separated from the uniforms and applied to a painter's canvas, and that doing so would not replicate the uniform itself. The designs were therefore eligible for copyright.

  One commentator noted the ruling set a "relatively low threshold," effectively ensuring that "all but the subtlest graphic designs will be able to gain copyright protection" once a court determines the designs have graphic qualities and could be applied to a painter's canvas. The case drew a practical line that industrial designers and fashion companies have navigated ever since.

• 7. Fair Use and Infringement

  ›

  Fair use is codified at Title 17, Section 107, which states that fair use of a copyrighted work "is not an infringement of copyright." Courts weigh four factors: the purpose and character of the use (including whether it is commercial or nonprofit); the nature of the copyrighted work; the amount of the work used; and the effect of the use on the potential market for the original. No single factor is decisive, and no formula exists to determine in advance what percentage of a work may be used freely. Transformative uses, those that add something new rather than merely repackaging the original, receive stronger protection under this framework.

  When infringement does occur, the financial stakes can be substantial. In Lowry's Reports, Inc. v. Legg Mason Inc., a 2003 case involving a publisher of stock analysis newsletters whose material was copied in-house, the jury awarded a total of $20 million. For willful infringement, statutory damages can reach $150,000 per work infringed. Criminal penalties in cases of willful infringement include fines up to $500,000 and imprisonment up to five years for a first offense, rising to $1 million and ten years for repeat offenses. Felony penalties for first offenses kick in at seven copies for audiovisual works and one hundred copies for sound recordings.

• 8. Government, Orphan Works, and Reform

  ›

  Works created by federal government employees within the scope of their employment carry no copyright. Laws, statutes, and court decisions at the federal, state, and local level belong to the public under the government edicts doctrine, which three Supreme Court cases established: Wheaton v. Peters in 1834, Banks v. Manchester in 1888, and Callaghan v. Myers in 1888. The Supreme Court extended this in Georgia v. Public.Resource.Org, Inc. in 2020, ruling that annotated versions of statutes or court decisions prepared by government employees as part of their duties are also ineligible for copyright.

  The Copyright Act of 1976 created a separate problem when it eliminated mandatory registration. Before that law, registration served as a central record of who owned what. Once registration became optional, tracking down rights holders became far harder. Works whose owners cannot be found are called orphan works, and potential users, filmmakers, biographers, and others must assume such works are still protected and investigate each one independently. Paul McCartney's reclaiming of U.S. publishing rights to early Beatles songs from Sony Music Publishing, beginning in October 2018, illustrates how the termination-of-transfer provisions can shift ownership back to creators. For works published before 1978, copyrights may revert after 56 years; for works published since 1978, that window opens after 35 years, provided the author sends a written termination notice at least two years before the effective date.
