Copying was widespread, in compliance with the law, but expansions of those laws intended to benefit literary works and responding to commercial music recording technology's reproducibility have led to stricter rules. Relatively recently, a normative view that copying in music is not desirable and lazy has become popular among professional musicians. Sound recordings, on the other hand, are subject to different rules and are not eligible for public domain status until , depending on the date and location of publishing. The Musopen project records music in the public domain for the purposes of making the music available to the general public in a high-quality audio format.
A public-domain film is a film that was released to public domain by its author or because its copyright has expired. In there are more than 2, films on public domain in every genre, from musicals to romance, horror to animated movies and noir to western movies. Pamela Samuelson has identified eight "values" that can arise from information and works in the public domain. Derivative works include translations , musical arrangements , and dramatizations of a work, as well as other forms of transformation or adaptation.
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 the U. Some works may never fully lapse into the public domain.

While the copyright has expired for the Peter Pan works by J. Barrie the play Peter Pan, or the Boy Who Wouldn't Grow Up and the novel Peter and Wendy in the United Kingdom, it was granted a special exception under the Copyright, Designs, and Patents Act Schedule 6 [38] that requires royalties to be paid for commercial performances, publications and broadcasts of the story of Peter Pan within the UK, as long as Great Ormond Street Hospital to whom Barrie gave the copyright continues to exist.
In a paying public domain regime, works that have entered the public domain after their copyright has expired, or traditional knowledge and traditional cultural expressions that have never been subject to copyright, are still subject to royalties payable to the state or to an authors' association. The user does not have to seek permission to copy, present or perform the work, but does have to pay the fee. Typically the royalties are directed to support of living artists. The Creative Commons proposed in the Public Domain Mark PDM as symbol to indicate that a work is free of known copyright restrictions and therefore in the public domain.
The Europeana databases use it, and for instance on the Wikimedia Commons in February 2. 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. However, translations or new formulations of these works may be copyrighted in themselves. Determination of whether a copyright has expired depends on an examination of the copyright in its source country.
In the United States, determining whether a work has entered the public domain or is still under copyright can be quite complex, primarily because copyright terms have been extended multiple times and in different ways—shifting over the course of the 20th century from a fixed-term based on first publication, with a possible renewal term , to a term extending to 50, then 70, years after the death of the author.
The claim that "pre works are in the public domain" is correct only for published works; unpublished works are under federal copyright for at least the life of the author plus 70 years. In most other countries that are signatories to the Berne Convention , copyright term is based on the life of the author, and extends to 50 or 70 years beyond the death of the author.
See List of countries' copyright lengths. Legal traditions differ on whether a work in the public domain can have its copyright restored. In the European Union, the Copyright Duration Directive was applied retroactively, restoring and extending the terms of copyright on material previously in the public domain.

We offer over expressive domain extensions to register right away, from classics like. One court, however, has concluded that these recordings are still protected by the state common law copyrights that govern U. Public domain related lists.
Term extensions by the U. However, the United States moved away from that tradition with the Uruguay Round Agreements Act , which removed from the public domain many foreign-sourced works that had previously not been in copyright in the US for failure to comply with US-based formalities requirements. Consequently, in the US, foreign-sourced works and US-sourced works are now treated differently, with foreign-sourced works remaining under copyright regardless of compliance with formalities, while domestically-sourced works may be in the public domain if they failed to comply with then-existing formalities requirements—a situation described as odd by some scholars, and unfair by some US-based rightsholders.
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.
The legal scholar Melville Nimmer has written that "it is axiomatic that material in the public domain is not protected by copyright, even when incorporated into a copyrighted work". Before in the US, works could be easily given into the public domain by just releasing it without an explicit Copyright notice. An alternative is for copyright holders to issue a licence which irrevocably grants as many rights as possible to the general public. There are multiple licenses which aim to release works into the public domain.
This is achieved by a public domain waiver statement and a fall-back all-permissive license, in case the waiver is not possible. The Unlicense offers a public domain waiver text with a fall-back public domain-like license inspired by permissive licenses but without attribution. In most countries, the term of rights for patents is 20 years, after which the invention becomes part of the public domain. In the United States, the contents of patents are considered valid and enforceable for 20 years from the date of filing within the United States or 20 years from the earliest date of filing if under 35 USC , , or c.
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", with an uppercase A, is still a trademark of the German company Bayer , while aspirin, with a lowercase "a", is not. So many copycat products entered the marketplace during the war that it was deemed generic just three years later. Bayer also lost the trademark in the same jurisdictions for "Heroin" which it trademarked a year before it trademarked Aspirin. Although Hormel resigned itself to genericide, [60] it has fought attempts by other companies to register " spam " as a trademark in relation to computer products.
Public Domain Day is an observance of when copyrights expire and works enter into the public domain.
