Public domain works are those whose intellectual property rights have expired, been forfeited, or are inapplicable. Examples include the works of Shakespeare and Beethoven, most of the early silent films, the formulae of Newtonian physics, and the patents on powered flight. The term is not normally applied to situations when the creator of a work retains residual rights, in which case use of the work is referred to as "under license" or with permission.
In informal usage, the public domain consists of works that are publicly available; while according to the formal definition it consists of works that are unavailable for private ownership or are available for public use. As rights are country-based and vary, a work may be subject to rights in one country and not in another. Some rights depend on registrations with a country-by-country basis, and the absence of registration in a particular country implies public domain status there.
Public domain did not come to fruition as a term until the mid-17th century, although as a concept "it can be traced back to the ancient Roman Law, as a preset system included in the property right system." The Romans had a large proprietary rights system where they defined "many things that cannot be privately owned" as res communes, res publicae and res universitatis. The term res commune was defined as "things that could be commonly enjoyed by mankind, such as air, sunlight and ocean." The term res publicae referred to things that were shared by all citizens, and the term res universitatis meant things that were owned by the municipalities of Rome. When looking at public domain from a historical perspective, one could say the construction of the idea of "public domain" sprouted from the concepts of res commune, res publicae, and res universitatis in early Roman Law.
When the first early copyright law was first established in Britain with the Statute of Anne in 1710, public domain did not appear. However, similar concepts were developed by British and French jurists in the eighteenth century. Instead of "public domain" they used terms such as publici juris or propriété publique to describe works that were not covered by copyright law. The phrase "fall in the public domain" can be traced to mid-nineteenth 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. 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 consists of works that are no longer in copyright term or were never protected by copyright law. According to James Boyle this definition underlines common usage of the term public domain and equates the public domain to public property and works in copyright to private property. However, the usage of the term public domain can be more granular, including for example uses of works in copyright permitted by copyright exceptions. Such a definition regards work in copyright as private property subject to fair use rights and limitation on ownership. A conceptual definition 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".

In attempting to map the public domain Pamela Samuelson has identified eight "values" that can arise from information and works in the public domain, though not every idea or work that is in the public domain necessarily has a value. Possible values include:
Derivative works include translations, musical arrangements, and dramatizations of a work, as well as other forms of transformation or adaptation. 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.
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.
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.
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 formulae 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.
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.
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 rather 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.
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."
In most countries the term for patents is 20 years, after which the invention becomes part of the public domain.
A trademark registration may remain in force indefinitely, or expire without specific regard to its age. For a trademark registration to remain valid, the owner must continue to use it. In some circumstances, such as disuse, failure to assert trademark rights, or common usage by the public without regard for its intended use, it could become generic, and therefore part of the public domain.
Because trademarks are registered with governments, some countries or trademark registries may recognize a mark, while others may have determined that it is generic and not allowable as a trademark in that registry. For example, the drug "acetylsalicylic acid" (2-acetoxybenzoic acid) is better known as aspirin in the United States—a generic term. In Canada, however, "Aspirin" is still a trademark of the German company Bayer. Bayer lost the trademark in the United States after World War I, when the mark was sold to an American firm. So many copy-cat products entered the marketplace during the war that it was deemed generic just three years later.
