Works are in the public domain if they are not covered by intellectual property rights at all, if the intellectual property rights have expired, and/or if the intellectual property rights are forfeited. Examples include the English language, the formulae of Newtonian physics, as well as the works of Shakespeare and the patents over powered flight. The phrase "fall in the public domain" can be traced to mid 19th Century France to describe the end of copyright term. The French poet Alfred de Vigny equated the expiration of copyright with a work falling "into the sink hole of the public domain" and if the public domain receives any attention from intellectual property lawyers it is still treated as little more than that which is left when intellectual property rights, such as copyright, patents and trademarks, expire or are abandoned. Copyright law was created by statute and all works created and published before copyright law was first established are in the public domain. In this historical context Paul Torremans describes copyright as a "little coral reef of private right jutting up from the ocean of the public domain." Because copyright law is different from country to country Pamela Samuelson has described the public domain as being "different sizes at different times in different countries".
Definitions of the boundaries of the public domain in relation to copyright, or intellectual property more generally, regard the public domain as a negative space, that is, it consist of works that are no longer in copyright term or were never protected by copyright law. More subtle definitions of the public domain move beyond those works that no longer receive legal protection under intellectual property law and incorporates all aspects of works which are not covered by the intellectual property doctrine, such as insubstantial parts of a copyrighted work or the statutory defined permitted acts and exceptions to copyright. A less legalistic definition of the public domain comes from Lange, who focused on what the public domain should be: "it should be a place of sanctuary for individual creative expression, a sanctuary conferring affirmative protection against the forces of private appropriation that threatened such expression". Patterson and Lindberg described the public domain not as a "territory", but rather as a concept: "There are certain materials - the air we breathe, sunlight, rain, space, life, creations, thoughts, feelings, ideas, words, numbers - not subject to private ownership. The materials that compose our cultural heritage must be free for all to use no less than matter necessary for biological survival." The term public domain may also be interchangeably used with other imprecise and/or undefined terms such as the "public sphere" or "commons", including concepts such as "commons of the mind", the "intellectual commons" and the "information commons". though not every idea or work that is in the public domain necessarily has a value. Possible values include:
Building blocks for the creation of new knowledge, examples include data, facts, ideas, theories and scientific principle.
Access to cultural heritage through information resources such as ancient Greek texts and Mozart’s symphonies.
Promoting education, through the spread of information, ideas and scientific principles.
Enabling follow-on innovation, through for example expired patents and copyright.
Enabling low cost access to information without the need to locate the owner or negotiate rights clearance and pay royalties, through for example expired copyrighted works or patents, and non-original data compilation.
Promoting public health and safety, through information and scientific principles.
Promoting the democratic process and values, through news, laws, regulation and judicial opinion.
Enabling competitive imitation, through for example expired patents and copyright, or publicly disclosed technologies that do not qualify for patient protection. Copyrighted works may not be used for derivative works without permission from the copyright owner, while public domain works can be freely used for derivative works without permission. Artworks that are public domain may also be reproduced photographically or artistically or used as the basis of new, interpretive works. Once works enter into the public domain, derivative works such as adaptations in book and film may increase noticeably, as happened with Frances Hodgson Burnett's novel The Secret Garden, which became public domain in 1987. As of 1999, the plays of Shakespeare, all public domain, had been used in more than 420 feature-length films. In addition to straightforward adaptation, they have been used as the launching point for transformative retellings such as Tom Stoppard's Rosencrantz and Guildenstern Are Dead and Troma Entertainment's Tromeo and Juliet. Marcel Duchamp's L.H.O.O.Q. is a derivative of Leonardo Da Vinci's Mona Lisa, one of thousands of derivative works based on the public domain painting. Copyright law, first established for books by the Statute of Anne 1709, is based on the concept of the individual author. In 18th century Europe, written culture was regarded as European, while oral culture was regarded as uncivilised and pre-modern. The concept of "folk-lore" was coined by William Thomas in 1846, describing "knowledge of the people", and in the late 19th century the fairy tales told by people living in the countryside were collected and published. While orally transmitted fairy tales were not covered by copyright law, and hence in the public domain, 18th century copyright law did apply to written folklore, hence the Brothers Grimm and others who recorded oral folklore owned the copyright on their publications. In the 20th century, the concept of authorship was extended to recorded musical works as the phonograph allowed for the fixation of oral transmissions.

The Little Mermaid is based on a wide range of
folklore and was in turn adapted to various media, including the 1989
Disney version. (Illustration 1911

The view that folklore and traditional knowledge were in the public domain and free for anybody to use was challenged by the newly independent African and Asian nations of the 1960s, who came under pressure to comply with the 1886
Berne Convention for the Protection of Literary and Artistic Works. African countries regarded folklore to be part of the "cultural heritage of the African nations" and the
Tunisian 1966 Copyright Act awarded copyright protection to folklore with the stated aim "to prevent folklore from falling into the hands of third parties who might wish to exploit them for commercial purposes". At the 1967 Stockholm Conference to amend the Berne Convention, India raised broader questions of individual authorship, arguing that "...works of folklore might represent the creative efforts of a number of unidentified indigenous authors. They were therefore not only anonymous works in the sense of the... Berne Convention, but also joint works, since in nearly all cases they were unfixed and represented a constantly changing apptern produced by successive performers and authors." As African nations opposed the inclusion of folklore under the "anonymous works" category of the Berne Convention, the Australian delegates conceded that "The whole structure of the Convention was designed to protect the rights of identifyable authors. With a work of folklore there was no such author". Eventually, folklore was not integrated into the Berne Convention and therefore its status is not regulated under
international copyright law, though countries may cover it in national copyright law. Whether or not indigenous works are in the public domain, as defined in the context of
intellectual property rights, is disputed and the public domain is not necessarily a concept recognised by indigenous peoples. As much of traditional knowledge has never been protected under intellectual property rights, they can not be said to have entered any public domain. On this point the
Tulalip Tribes of
Washington, United States, has commented that "...open sharing does not automatically confer a right to use the knowledge (of indigenous people)... traditional cultural expressions are not in the public domain because indigenous peoples have failed to take the steps necessary to protect the knowledge in the Western intellectual property system, but form a failure of governments and citizens to recognise and respect the customary laws regulating their use". In the 19th century, the
Brothers Grimm and
Hans Christian Andersen, three of the most influential collectors of European folklore, published collections of folklore, edited and altered, based on existing folklore and fairy tales. As their works passed into the public domain
Walt Disney adapted them into animated film, including
Snow White and the Seven Dwarfs (1937),
Cinderella (1950) and
The Little Mermaid (1989). Disney also adapted folklore from other cultures, such as
Aladdin (1992), and the Disney fairy tales are now often the only version known, with the older versions largely unknown.
The public domain in the information society
According to
Bernt Hugenholtz and Lucie Guibault the public domain is under pressure from the "commodification of information" as items of information that previously had little or no economic value have acquired independent economic value in the information age, such as factual data,
personal data,
genetic information and pure
ideas. The commodification of information is taking place through
intellectual property law,
contract law, as well as broadcasting and telecommunications law.
Perpetual copyright
Some works may never fully lapse into the public domain. A perpetual
crown copyright is held for the
Authorized King James Version of the Bible in the UK. While the copyright of the play
Peter Pan, or the Boy Who Wouldn't Grow Up by
J. M. Barrie has expired in the United Kingdom, it was granted a special exception under
the Copyright, Designs and Patents Act 1988 (Schedule 6) that requires royalties to be paid for performances within the UK, so long as
Great Ormond Street Hospital (to whom Barrie gave the rights) continues to exist.
Public domain in copyrightable works
Works not covered by copyright law
The underlying
idea that is expressed or manifested in the creation of a work generally cannot be the subject of copyright law (see
idea-expression divide). Mathematical formulæ will therefore generally form part of the public domain, to the extent that their expression in the form of software is not covered by copyright; however, algorithms can be the subject of a
software patent in some jurisdictions.
Works created before the existence of copyright and patent laws also form part of the public domain. For example, the Bible and the inventions of Archimedes are in the public domain, but copyright may exist in translations or new formulations of these works.
Expiration of copyright
The expiration of a copyright is more complex than that of a patent. Historically the
United States has specified terms of a number of years following creation or publication; this number has been increased several times. Most other countries specify terms of a number of years following the death of the last surviving creator; this number varies from one country to another (50 years and 70 years are the most common), and has also been increased in many of them. See
List of countries' copyright length. Legal traditions differ on whether a work in the public domain can have its copyright restored. Term extensions by the U.S. and Australia generally have not removed works from the public domain, but merely delayed the addition of works to it. By contrast, a European Union
directive harmonizing the term of copyright protection was applied retroactively, restoring and extending the terms of copyright on material previously in the public domain.
Government work
Works of the United States Government and various other governments are excluded from copyright law and may therefore be considered to be in the public domain in their respective countries. In the United States, when copyrighted material is enacted into the law, it enters the public domain. Thus, the
building codes, when enacted, are in the public domain. They may also be in the public domain in other countries as well. "It is axiomatic that material in the public domain is not protected by copyright, even when incorporated into a copyrighted work."
Definition
The definition of public domain is not uniform and may not only include completed works, but also permitted uses of works still covered by intellectual property rights, such as for example the
right to excerpt short quotations in a review. This definition divides areas of
private property from areas of the public domain. For example,
Mozart's plot is
public property, and
Britney Spears' music is private property.
Generic trademarks
Trademarks currently thought to be in danger of being generic include Kleenex,
iPod,
Jell-O,
Band-Aid,
Rollerblade,
Google,
Spam,
Hoover,
Xerox, and
Sheetrock. Google vigorously defends its trademark rights. Although
Hormel resigned itself to genericide, it has fought attempts by other companies to register "spam" as a trademark in relation to computer products.
Public domain works
Several artists and advocates of the public domain have created projects that call attention to the issue, supporting the free and public use of space and items such as software.
