Copyright

The concept of copyright developed after the printing press came into use in Europe^[16] in the 15th and 16th centuries.^[17] It was associated with a common law and rooted in the civil law system.^[18] The printing press made it much cheaper to produce works, but as there was initially no copyright law, anyone could buy or rent a press and print any text.

Popular new works were immediately re-set and re-published by competitors, so printers needed a constant stream of new material. Fees paid to authors for new works were high and significantly supplemented the incomes of many academics.^[19]

Printing brought profound social changes. The rise in literacy across Europe led to a dramatic increase in the demand for reading matter.^[16] Prices of reprints were low, so publications could be bought by poorer people, creating a mass audience. In German-language markets before the advent of copyright, technical materials, like academic papers and handbooks, were inexpensive and widely available; it has been suggested this contributed to Germany's industrial and economic success.^[19]

The concept of copyright first developed in England. In reaction to the printing of "scandalous books and pamphlets", the English Parliament passed the Licensing of the Press Act 1662,^[16] which required all intended publications to be registered with the government-approved Stationers' Company, giving the Stationers the right to regulate what material could be printed.^[20]

The Statute of Anne, enacted in 1710 in England and Scotland, provided the first legislation to protect copyrights (but not authors' rights). The Copyright Act 1814 extended more rights for authors but did not protect British publications from being reprinted in the US. The Berne International Copyright Convention of 1886 finally provided protection for authors among the countries who signed the agreement, although the US did not join the Berne Convention until 1989.^[21]

In the US, the Constitution grants Congress the right to establish copyright and patent laws. Shortly after the Constitution was passed, Congress enacted the Copyright Act of 1790, modeling it after the Statute of Anne. While the national law protected authors' published works, authority was granted to the states to protect authors' unpublished works. The most recent major overhaul of copyright in the US, the Copyright Act of 1976, extended federal copyright to works as soon as they are created and "fixed", without requiring publication or registration. State law continues to apply to unpublished works that are not otherwise copyrighted by federal law. This act also changed the calculation of copyright term from a fixed term (then a maximum of fifty-six years) to "life of the author plus 50 years". These changes brought the US closer to conformity with the Berne Convention, and in 1989 the United States further revised its copyright law and joined the Berne Convention officially.^[21]

Copyright laws allow products of creative human activities, such as literary and artistic production, to be preferentially exploited and thus incentivized. Different cultural attitudes, social organizations, economic models and legal frameworks are seen to account for why copyright emerged in Europe and not, for example, in Asia. In the Middle Ages in Europe, there was generally a lack of any concept of literary property due to the general relations of production, the specific organization of literary production and the role of culture in society. The latter refers to the tendency of oral societies, such as that of Europe in the medieval period, to view knowledge as the product and expression of the collective, rather than to see it as individual property. However, with copyright laws, intellectual production comes to be seen as a product of an individual, with attendant rights. The most significant point is that patent and copyright laws support the expansion of the range of creative human activities that can be commodified. This parallels the ways in which capitalism led to the commodification of many aspects of social life that earlier had no monetary or economic value perse.^[22]

Copyright has developed into a concept that has a significant effect on nearly every modern industry, including not just literary work, but also forms of creative work such as sound recordings, films, photographs, software, and architecture.

Often seen as the first real copyright law, the 1709 British Statute of Anne gave authors and the publishers to whom they did chose to license their works, the right to publish the author's creations for a fixed period, after which the copyright expired.^[23] It was "An Act for the Encouragement of Learning, by Vesting the Copies of Printed Books in the Authors or the Purchasers of such Copies, during the Times therein mentioned."

The act also alluded to individual rights of the artist. It began:

"Whereas Printers, Booksellers, and other Persons, have of late frequently taken the Liberty of Printing ... Books, and other Writings, without the Consent of the Authors ... to their very great Detriment, and too often to the Ruin of them and their Families:".^[24]

A right to benefit financially from the work is articulated, and court rulings and legislation have recognized a right to control the work, such as ensuring that the integrity of it is preserved. An irrevocable right to be recognized as the work's creator appears in some countries' copyright laws.

The Copyright Clause of the United States, Constitution (1787) authorized copyright legislation: "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." That is, by guaranteeing them a period of time in which they alone could profit from their works, they would be enabled and encouraged to invest the time required to create them, and this would be good for society as a whole. A right to profit from the work has been the philosophical underpinning for much legislation extending the duration of copyright, to the life of the creator and beyond, to their heirs. Yet scholars like Lawrence Lessig have argued that copyright terms have been extended beyond the scope imagined by the Framers. Lessig refers to the Copyright Clause as the "Progress Clause" to emphasize the social dimension of intellectual property rights.^[25]

The original length of copyright in the United States was 14 years, and it had to be explicitly applied for. If the author wished, they could apply for a second 14‑year monopoly grant, but after that the work entered the public domain, so it could be used and built upon by others.

In many jurisdictions of the European continent, comparable legal concepts to copyright did exist from the 16th century on but did change under Napoleonic rule into another legal concept: authors' rights or creator's right laws, from French: droits d'auteur and German Urheberrecht.^[26][27] In many modern-day publications the terms copyright and authors' rights are being mixed, or used as translations, but in a juridical sense the legal concepts do essentially differ.^[28][29] Authors' rights are, generally speaking, from the start absolute property rights of an author of original work that one does not have to apply for. The law is automatically connecting an original work as intellectual property to its creator.^[30] Although the concepts throughout the years have been mingled globally, due to international treaties and contracts, distinct differences between jurisdictions continue to exist.^[31]

Creator's law was enacted rather late in German speaking states and the economic historian Eckhard Höffner argues that the absence of possibilities to maintain copyright laws in all these states in the early 19th century, encouraged the publishing of low-priced paperbacks for the masses. This was profitable for authors and led to a proliferation of books, enhanced knowledge, and was ultimately an important factor in the ascendency of Germany as a power during that century.^[32] After the introduction of creator's rights, German publishers started to follow English customs, in issuing only expensive book editions for wealthy customers.^[33]

Empirical evidence derived from the exogenous differential introduction of author's right (Italian: diritto d'autore) in Napoleonic Italy shows that "basic copyrights increased both the number and the quality of operas, measured by their popularity and durability".^[34]

The 1886 Berne Convention first established recognition of authors' rights among sovereign nations, rather than merely bilaterally. Under the Berne Convention, protective rights for creative works do not have to be asserted or declared, as they are automatically in force at creation: an author need not "register" or "apply for" these protective rights in countries adhering to the Berne Convention.^[35] As soon as a work is "fixed", that is, written or recorded on some physical medium, its author is automatically entitled to all intellectual property rights in the work, and to any derivative works unless and until the author explicitly disclaims them, or until the rights expires. The Berne Convention also resulted in foreign authors being treated equivalently to domestic authors, in any country signed onto the convention. The UK signed the Berne Convention in 1887 but did not implement large parts of it until 100 years later with the passage of the Copyright, Designs and Patents Act 1988. Specially, for educational and scientific research purposes, the Berne Convention provides the developing countries issue compulsory licenses for the translation or reproduction of copyrighted works within the limits prescribed by the convention. This was a special provision that had been added at the time of 1971 revision of the convention, because of the strong demands of the developing countries. The United States did not sign the Berne Convention until 1989.^[36]

The United States and most Latin American countries instead entered into the Buenos Aires Convention in 1910, which required a copyright notice on the work (such as all rights reserved), and permitted signatory nations to limit the duration of copyrights to shorter and renewable terms.^[37][38][39] The Universal Copyright Convention was drafted in 1952 as another less demanding alternative to the Berne Convention, and ratified by nations such as the Soviet Union and developing nations.

The regulations of the Berne Convention are incorporated into the World Trade Organization's TRIPS agreement (1995), thus giving the Berne Convention effectively near-global application.^[40]

In 1961, the United International Bureaux for the Protection of Intellectual Property signed the Rome Convention for the Protection of Performers, Producers of Phonograms and Broadcasting Organizations. In 1996, this organization was succeeded by the founding of the World Intellectual Property Organization, which launched the 1996 WIPO Performances and Phonograms Treaty and the 2002 WIPO Copyright Treaty, which enacted greater restrictions on the use of technology to copy works in the nations that ratified it. The Trans-Pacific Partnership includes intellectual property provisions relating to copyright.

Copyright laws and authors' right laws are standardized somewhat through these international conventions such as the Berne Convention and Universal Copyright Convention. These multilateral treaties have been ratified by nearly all countries, and international organizations such as the European Union require their member states to comply with them. All member states of the World Trade Organization are obliged to establish minimum levels of copyright protection. Nevertheless, important differences between the national regimes continue to exist.^[31][28]

The original holder of the copyright may be the employer of the author rather than the author themself if the work is a "work for hire".^[41][42] For example, in English law the Copyright, Designs and Patents Act 1988 provides that if a copyrighted work is made by an employee in the course of that employment, the copyright is automatically owned by the employer which would be a "Work for Hire". Typically, the first owner of a copyright is the person who created the work i.e. the author.^[43] But when more than one person creates the work, then a case of joint authorship can be made provided some criteria are met.

Copyright may apply to a wide range of creative, intellectual, or artistic forms, or "works". Specifics vary by jurisdiction, but these can include poems, theses, fictional characters, plays and other literary works, motion pictures, choreography, musical compositions, sound recordings, paintings, drawings, sculptures, photographs, computer software, radio and television broadcasts, and industrial designs. Graphic designs and industrial designs may have separate or overlapping laws applied to them in some jurisdictions.^[44][45]

Copyright does not cover ideas and information themselves, only the form or manner in which they are expressed. For example, the copyright to a Mickey Mouse cartoon restricts others from making copies of the cartoon or creating derivative works based on Disney's particular anthropomorphic mouse, but does not prohibit the creation of other works about anthropomorphic mice in general, so long as they are different enough not to be judged copies of Disney's.^[46]

Typically, a work must meet minimal standards of originality in order to qualify for copyright, and the copyright expires after a set period of time (some jurisdictions may allow this to be extended). Different countries impose different tests, although generally the requirements are low; in the United Kingdom there has to be some "skill, labour, and judgment" that has gone into it.^[47] In Australia and the United Kingdom it has been held that a single word is insufficient to comprise a copyright work. However, single words or a short string of words can sometimes be registered as a trademark instead.

Copyright law recognizes the right of an author based on whether the work actually is an original creation, rather than based on whether it is unique; two authors may own copyright on two substantially identical works, if it is determined that the duplication was coincidental, and neither was copied from the other.

In all countries where the Berne Convention standards apply, copyright is automatic and need not be obtained through official registration with any government office. Once an idea has been reduced to tangible form, for example by securing it in a fixed medium (such as a drawing, sheet music, photograph, a videotape, or a computer file), the copyright holder is entitled to enforce their exclusive rights.^[35] However, while registration is not needed to exercise copyright, in jurisdictions where the laws provide for registration, it serves as prima facie evidence of a valid copyright and enables the copyright holder to seek statutory damages and attorney's fees.^[48] (In the US, registering after an infringement only enables one to receive actual damages and lost profits.)

A widely circulated strategy to avoid the cost of copyright registration is referred to as the poor man's copyright. It proposes that the creator send the work to themself in a sealed envelope by registered mail, using the postmark to establish the date. This technique has not been recognized in any published opinions of the United States courts. The United States Copyright Office says the technique is not a substitute for actual registration.^[49] The United Kingdom Intellectual Property Office discusses the technique and notes that the technique (as well as commercial registries) does not constitute dispositive proof that the work is original or establish who created the work.^[50][51]

The Berne Convention allows member countries to decide whether creative works must be "fixed" to enjoy copyright. Article 2, Section 2 of the Berne Convention states:

"It shall be a matter for legislation in the countries of the Union to prescribe that works in general or any specified categories of works shall not be protected unless they have been fixed in some material form."

Some countries do not require that a work be produced in a particular form to obtain copyright protection. For instance, Spain, France, and Australia do not require fixation for copyright protection. The United States and Canada, on the other hand, require that most works must be "fixed in a tangible medium of expression" to obtain copyright protection. US law requires that the fixation be stable and permanent enough to be "perceived, reproduced or communicated for a period of more than transitory duration". Similarly, Canadian courts consider fixation to require that the work be "expressed to some extent at least in some material form, capable of identification and having a more or less permanent endurance".^[52]

Note this provision of US law:

c) Effect of Berne Convention.—No right or interest in a work eligible for protection under this title may be claimed by virtue of, or in reliance upon, the provisions of the Berne Convention, or the adherence of the United States thereto. Any rights in a work eligible for protection under this title that derive from this title, other Federal or State statutes, or the common law, shall not be expanded or reduced by virtue of, or in reliance upon, the provisions of the Berne Convention, or the adherence of the United States thereto.^[53]

Before 1989, United States law required the use of a copyright notice, consisting of the copyright symbol (©, the letter C inside a circle; Unicode U+00A9 © COPYRIGHT SIGN), the abbreviation "Copr.", or the word "Copyright", followed by the year of the first publication of the work and the name of the copyright holder.^[54][55] Several years may be noted if the work has gone through substantial revisions. The proper copyright notice for sound recordings of musical or other audio works is a sound recording copyright symbol (℗, the letter P inside a circle, Unicode U+2117 ℗ SOUND RECORDING COPYRIGHT), which indicates a sound recording copyright, with the letter P indicating a "phonorecord". In addition, the phrase All rights reserved which indicates that the copyright holder reserves, or holds for their own use was once required to assert copyright, but that phrase is now legally obsolete. Almost everything on the Internet has some sort of copyright attached to it. Whether these things are watermarked, signed, or have any other sort of indication of the copyright is a different story however.^[56]

In 1989 the United States enacted the Berne Convention Implementation Act, amending the Copyright Act of 1976 to conform to most of the provisions of the Berne Convention. As a result, the use of copyright notices has become optional to claim copyright, because the Berne Convention makes copyright automatic.^[57] However, the lack of notice of copyright using these marks may have consequences in terms of reduced damages in an infringement lawsuit– using notices of this form may reduce the likelihood of a defense of "innocent infringement" being successful.^[58]

In the UK, the publisher of a work automatically owns the copyright in the "typographical arrangement of a published work", i.e. its layout and general appearance as a published work. This copyright lasts for 25 years after the end of the year in which the edition containing that arrangement was first published.^[59]

Copyrights are generally enforced by the holder in a civil law court, but there are also criminal infringement statutes in some jurisdictions. While central registries are kept in some countries which aid in proving claims of ownership, registering does not necessarily prove ownership, nor does the fact of copying (even without permission) necessarily prove that copyright was infringed. Criminal sanctions are generally aimed at serious counterfeiting activity, but are now becoming more commonplace as copyright collectives such as the RIAA are increasingly targeting the file sharing home Internet user. Thus far, however, most such cases against file sharers have been settled out of court. (See Legal aspects of file sharing)

In most jurisdictions the copyright holder must bear the cost of enforcing copyright. This will usually involve engaging legal representation, administrative or court costs. In light of this, many copyright disputes are settled by a direct approach to the infringing party in order to settle the dispute out of court.

"... by 1978, the scope was expanded to apply to any 'expression' that has been 'fixed' in any medium, this protection granted automatically whether the maker wants it or not, no registration required."^[60]

With older technology like paintings, books, phonographs, and film, it is generally not feasible for consumers to make copies on their own, so producers can simply require payment when transferring physical possession of the storage medium. The equivalent for digital online content is a paywall.

The introduction of the photocopier, cassette tape, and videotape made it easier for consumers to copy materials like books and music, but each time a copy was made, it lost some fidelity. Digital media like text, audio, video, and software (even when stored on physical media like compact discs and DVDs) can be copied losslessly, and shared on the Internet, creating a much bigger threat to producer revenue. Some have used digital rights management technology to restrict non-playback access through encryption and other means. Digital watermarks can be used to trace copies, deterring infringement with a more credible threat of legal consequences. Copy protection is used for both digital and pre-Internet electronic media.

For a work to be considered to infringe upon copyright, its use must have occurred in a nation that has domestic copyright laws or adheres to a bilateral treaty or established international convention such as the Berne Convention or WIPO Copyright Treaty. Improper use of materials outside of legislation is deemed "unauthorized edition", not copyright infringement.^[61]

Statistics regarding the effects of copyright infringement are difficult to determine. Studies have attempted to determine whether there is a monetary loss for industries affected by copyright infringement by predicting what portion of pirated works would have been formally purchased if they had not been freely available.^[62] Other reports indicate that copyright infringement does not have an adverse effect on the entertainment industry, and can have a positive effect.^[63] In particular, a 2014 university study concluded that free music content, accessed on YouTube, does not necessarily hurt sales, instead has the potential to increase sales.^[64]

According to the IP Commission Report the annual cost of intellectual property infringement to the US economy "continues to exceed $225 billion in counterfeit goods, pirated software, and theft of trade secrets and could be as high as $600 billion."^[65] A 2019 study sponsored by the US Chamber of Commerce Global Innovation Policy Center (GIPC), in partnership with NERA Economic Consulting "estimates that global online piracy costs the U.S. economy at least $29.2 billion in lost revenue each year."^[66] An August 2021 report by the Digital Citizens Alliance states that "online criminals who offer stolen movies, TV shows, games, and live events through websites and apps are reaping $1.34 billion in annual advertising revenues." This comes as a result of users visiting pirate websites who are then subjected to pirated content, malware, and fraud.^[67]

According to World Intellectual Property Organisation, copyright protects two types of rights. Economic rights allow right owners to derive financial reward from the use of their works by others. Moral rights allow authors and creators to take certain actions to preserve and protect their link with their work. The author or creator may be the owner of the economic rights, or those rights may be transferred to one or more copyright owners. Many countries do not allow the transfer of moral rights.^[68]

With any kind of property, its owner may decide how it is to be used, and others can use it lawfully only if they have the owner's permission, often through a license. The owner's use of the property must, however, respect the legally recognised rights and interests of other members of society. So the owner of a copyright-protected work may decide how to use the work and may prevent others from using it without permission. National laws usually grant copyright owners exclusive rights to allow third parties to use their works, subject to the legally recognised rights and interests of others.^[68] Most copyright laws state that authors or other right owners have the right to authorise or prevent certain acts in relation to a work. Right owners can authorise or prohibit:

• reproduction of the work in various forms, such as printed publications or sound recordings;
• distribution of copies of the work;
• public performance of the work;
• broadcasting or other communication of the work to the public;
• translation of the work into other languages; and
• adaptation of the work, such as turning a novel into a screenplay.

Moral rights are concerned with the non-economic rights of a creator. They protect the creator's connection with a work as well as the integrity of the work. Moral rights are only accorded to individual authors and in many national laws they remain with the authors even after the authors have transferred their economic rights. In some EU countries, such as France, moral rights last indefinitely. In the UK, however, moral rights are finite. That is, the right of attribution and the right of integrity last only as long as the work is in copyright. When the copyright term comes to an end, so too do the moral rights in that work. This is just one reason why the moral rights regime within the UK is often regarded as weaker or inferior to the protection of moral rights in continental Europe and elsewhere in the world.^[69] The Berne Convention, in Article 6bis, requires its members to grant authors the following rights:

1. the right to claim authorship of a work (sometimes called the right of paternity or the right of attribution); and
2. the right to object to any distortion or modification of a work, or other derogatory action in relation to a work, which would be prejudicial to the author's honour or reputation (sometimes called the right of integrity).

These and other similar rights granted in national laws are generally known as the moral rights of authors. The Berne Convention requires these rights to be independent of authors' economic rights. Moral rights are only accorded to individual authors and in many national laws they remain with the authors even after the authors have transferred their economic rights. This means that even where, for example, a film producer or publisher owns the economic rights in a work, in many jurisdictions the individual author continues to have moral rights.^[68] Recently, as a part of the debates being held at the US Copyright Office on the question of inclusion of Moral Rights as a part of the framework of the Copyright Law in United States, the Copyright Office concluded that many diverse aspects of the current moral rights patchwork – including copyright law's derivative work right, state moral rights statutes, and contract law – are generally working well and should not be changed. Further, the Office concludes that there is no need for the creation of a blanket moral rights statute at this time. However, there are aspects of the US moral rights patchwork that could be improved to the benefit of individual authors and the copyright system as a whole.^[70]

In the copyright law of the United States, several exclusive rights are granted to the holder of a copyright, as are listed below:

• protection of the work;
• to determine and decide how, and under what conditions, the work may be marketed, publicly displayed, reproduced, distributed, etc.
• to produce copies or reproductions of the work and to sell those copies; (including, typically, electronic copies)
• to import or export the work;
• to create derivative works; (works that adapt the original work)
• to perform or display the work publicly;
• to sell or cede these rights to others;
• to transmit or display by radio, video or internet.^[44]

The basic right when a work is protected by copyright is that the holder may determine and decide how and under what conditions the protected work may be used by others. This includes the right to decide to distribute the work for free. This part of copyright is often overseen. The phrase "exclusive right" means that only the copyright holder is free to exercise those rights, and others are prohibited from using the work without the holder's permission. Copyright is sometimes called a "negative right", as it serves to prohibit certain people (e.g., readers, viewers, or listeners, and primarily publishers and would be publishers) from doing something they would otherwise be able to do, rather than permitting people (e.g., authors) to do something they would otherwise be unable to do. In this way it is similar to the unregistered design right in English law and European law. The rights of the copyright holder also permit them to not use or exploit their copyright, for some or all of the term. There is, however, a critique which rejects this assertion as being based on a philosophical interpretation of copyright law that is not universally shared. There is also debate on whether copyright should be considered a property right or a moral right.^[71]

UK copyright law gives creators both economic rights and moral rights. While 'copying' someone else's work without permission may constitute an infringement of their economic rights, that is, the reproduction right or the right of communication to the public, whereas, 'mutilating' it might infringe the creator's moral rights. In the UK, moral rights include the right to be identified as the author of the work, which is generally identified as the right of attribution, and the right not to have your work subjected to 'derogatory treatment', that is the right of integrity.^[69]

Indian copyright law is at parity with the international standards as contained in TRIPS. The Indian Copyright Act, 1957, pursuant to the amendments in 1999, 2002 and 2012, fully reflects the Berne Convention and the Universal Copyrights Convention, to which India is a party. India is also a party to the Geneva Convention for the Protection of Rights of Producers of Phonograms and is an active member of the World Intellectual Property Organization (WIPO) and United Nations Educational, Scientific and Cultural Organization (UNESCO). The Indian system provides both the economic and moral rights under different provisions of its Indian Copyright Act of 1957.^[72]

Copyright subsists for a variety of lengths in different jurisdictions. The length of the term can depend on several factors, including the type of work (e.g. musical composition, novel), whether the work has been published, and whether the work was created by an individual or a corporation. In most of the world, the default length of copyright is the life of the author plus either 50 or 70 years. In the United States, the term for most existing works is a fixed number of years after the date of creation or publication. Under most countries' laws (for example, the United States^[73] and the United Kingdom),^[74] copyrights expire at the end of the calendar year in which they would otherwise expire.

The length and requirements for copyright duration are subject to change by legislation, and since the early 20th century there have been a number of adjustments made in various countries, which can make determining the duration of a given copyright somewhat difficult. For example, the United States used to require copyrights to be renewed after 28 years to stay in force, and formerly required a copyright notice upon first publication to gain coverage. In Italy and France, there were post-wartime extensions that could increase the term by approximately 6 years in Italy and up to about 14 in France. Many countries have extended the length of their copyright terms (sometimes retroactively). International treaties establish minimum terms for copyrights, but individual countries may enforce longer terms than those.^[75]

In the United States, all books and other works, except for sound recordings, published before 1929 have expired copyrights and are in the public domain. The applicable date for sound recordings in the United States is before 1923.^[76] In addition, works published before 1964 that did not have their copyrights renewed 28 years after first publication year also are in the public domain. Hirtle points out that the great majority of these works (including 93% of the books) were not renewed after 28 years and are in the public domain.^[77] Books originally published outside the US by non-Americans are exempt from this renewal requirement, if they are still under copyright in their home country.

But if the intended exploitation of the work includes publication (or distribution of derivative work, such as a film based on a book protected by copyright) outside the US, the terms of copyright around the world must be considered. If the author has been dead more than 70 years, the work is in the public domain in most, but not all, countries.

In 1998, the length of a copyright in the United States was increased by 20 years under the Copyright Term Extension Act. This legislation was the subject of substantial criticism following allegations that the bill was strongly promoted by corporations which had valuable copyrights which otherwise would have expired.^[78]

In many jurisdictions, copyright law makes exceptions to these restrictions when the work is copied for the purpose of commentary or other related uses. United States copyright law does not cover names, titles, short phrases or listings (such as ingredients, recipes, labels, or formulas).^[79] However, there are protections available for those areas copyright does not cover, such as trademarks and patents.

The idea–expression divide differentiates between ideas and expression, and states that copyright protects only the original expression of ideas, and not the ideas themselves. This principle, first clarified in the 1879 case of Baker v. Selden, has since been codified by the Copyright Act of 1976 at 17 U.S.C. § 102(b).

Copyright law does not restrict the owner of a copy from reselling legitimately obtained copies of copyrighted works, provided that those copies were originally produced by or with the permission of the copyright holder. It is therefore legal, for example, to resell a copyrighted book or CD. In the United States this is known as the first-sale doctrine, and was established by the courts to clarify the legality of reselling books in second-hand bookstores.

Some countries may have parallel importation restrictions that allow the copyright holder to control the aftermarket. This may mean for example that a copy of a book that does not infringe copyright in the country where it was printed does infringe copyright in a country into which it is imported for retailing. The first-sale doctrine is known as exhaustion of rights in other countries and is a principle which also applies, though somewhat differently, to patent and trademark rights. While this doctrine permits the transfer of the particular legitimate copy involved, it does not permit making or distributing additional copies.

In Kirtsaeng v. John Wiley & Sons, Inc.,^[80] in 2013, the United States Supreme Court held in a 6–3 decision that the first-sale doctrine applies to goods manufactured abroad with the copyright owner's permission and then imported into the US without such permission. The case involved a plaintiff who imported Asian editions of textbooks that had been manufactured abroad with the publisher-plaintiff's permission. The defendant, without permission from the publisher, imported the textbooks and resold on eBay. The Supreme Court's holding severely limits the ability of copyright holders to prevent such importation.

In addition, copyright, in most cases, does not prohibit one from acts such as modifying, defacing, or destroying one's own legitimately obtained copy of a copyrighted work, so long as duplication is not involved. However, in countries that implement moral rights, a copyright holder can in some cases successfully prevent the mutilation or destruction of a work that is publicly visible.

Copyright does not prohibit all copying or replication. In the United States, the fair use doctrine, codified by the Copyright Act of 1976 as 17 U.S.C. Section 107, permits some copying and distribution without permission of the copyright holder or payment to same. The statute does not clearly define fair use, but instead gives four non-exclusive factors to consider in a fair use analysis. Those factors are:

1. the purpose and character of one's use;
2. the nature of the copyrighted work;
3. what amount and proportion of the whole work was taken;
4. the effect of the use upon the potential market for or value of the copyrighted work.^[81]

In the United Kingdom and many other Commonwealth countries, a similar notion of fair dealing was established by the courts or through legislation. The concept is sometimes not well defined; however, in Canada, private copying for personal use has been expressly permitted by statute since 1999. In Alberta (Education) v. Canadian Copyright Licensing Agency (Access Copyright), 2012 SCC 37, the Supreme Court of Canada concluded that limited copying for educational purposes could also be justified under the fair dealing exemption. In Australia, the fair dealing exceptions under the Copyright Act 1968 (Cth) are a limited set of circumstances under which copyrighted material can be legally copied or adapted without the copyright holder's consent. Fair dealing uses are research and study; review and critique; news reportage and the giving of professional advice (i.e. legal advice). Under current Australian law, although it is still a breach of copyright to copy, reproduce or adapt copyright material for personal or private use without permission from the copyright owner, owners of a legitimate copy are permitted to "format shift" that work from one medium to another for personal, private use, or to "time shift" a broadcast work for later, once and only once, viewing or listening. Other technical exemptions from infringement may also apply, such as the temporary reproduction of a work in machine readable form for a computer.

In the United States the AHRA (Audio Home Recording Act Codified in Section 10, 1992) prohibits action against consumers making noncommercial recordings of music, in return for royalties on both media and devices plus mandatory copy-control mechanisms on recorders.

Section 1008. Prohibition on certain infringement actions No action may be brought under this title alleging infringement of copyright based on the manufacture, importation, or distribution of a digital audio recording device, a digital audio recording medium, an analog recording device, or an analog recording medium, or based on the noncommercial use by a consumer of such a device or medium for making digital musical recordings or analog musical recordings.

Later acts amended US copyright law so that for certain purposes making 10 copies or more is construed to be commercial, but there is no general rule permitting such copying. Indeed, making one complete copy of a work, or in many cases using a portion of it, for commercial purposes will not be considered fair use. The Digital Millennium Copyright Act prohibits the manufacture, importation, or distribution of devices whose intended use, or only significant commercial use, is to bypass an access or copy control put in place by a copyright owner.^[44][82][83] An appellate court has held that fair use is not a defense to engaging in such distribution.^{[citation needed]} In Lenz v. Universal Music Corp., the United States Court of Appeals for the Ninth Circuit affirmed the lower court decision, holding that "fair use is 'authorized by the law' and a copyright holder must consider the existence of fair use before sending a takedown notification" under the Digital Millennium Copyright Act.^[84]

EU copyright laws recognise the right of EU member states to implement some national exceptions to copyright. Examples of those exceptions are:

• photographic reproductions on paper or any similar medium of works (excluding sheet music) provided that the rightholders receives fair compensation;
• reproduction made by libraries, educational establishments, museums or archives, which are non-commercial;
• archival reproductions of broadcasts;
• uses for the benefit of people with a disability;
• for demonstration or repair of equipment;
• for non-commercial research or private study;
• when used in parody.

It is legal in several countries including the United Kingdom and the United States to produce alternative versions (for example, in large print or braille) of a copyrighted work to provide improved access to a work for blind and visually impaired people without permission from the copyright holder.^[85][86]

In the US there is a Religious Service Exemption (1976 law, section 110[3]), namely "performance of a non-dramatic literary or musical work or of a dramatico-musical work of a religious nature or display of a work, in the course of services at a place of worship or other religious assembly" shall not constitute infringement of copyright.^[87]

In Canada, items deemed useful articles such as clothing designs are exempted from copyright protection under the Copyright Act if reproduced more than 50 times.^[88] Fast fashion brands may reproduce clothing designs from smaller companies without violating copyright protections.^[89]

A copyright, or aspects of it (e.g. reproduction alone, all but moral rights), may be assigned or transferred from one party to another.^[90] For example, a musician who records an album will often sign an agreement with a record company in which the musician agrees to transfer all copyright in the recordings in exchange for royalties and other considerations. The creator (and original copyright holder) benefits, or expects to, from production and marketing capabilities far beyond those of the author. In the digital age of music, music may be copied and distributed at minimal cost through the Internet; however, the record industry attempts to provide promotion and marketing for the artist and their work so it can reach a much larger audience. A copyright holder need not transfer all rights completely, though many publishers will insist. Some of the rights may be transferred, or else the copyright holder may grant another party a non-exclusive license to copy or distribute the work in a particular region or for a specified period of time.

A transfer or license may have to meet particular formal requirements in order to be effective,^[91] for example under the Australian Copyright Act 1968 the copyright itself must be expressly transferred in writing. Under the US Copyright Act, a transfer of ownership in copyright must be memorialized in a writing signed by the transferor. For that purpose, ownership in copyright includes exclusive licenses of rights. Thus, exclusive licenses, to be effective, must be granted in a written instrument signed by the grantor. No special form of transfer or grant is required. A simple document that identifies the work involved and the rights being granted is sufficient. Non-exclusive grants (often called non-exclusive licenses) need not be in writing under US law. They can be oral or even implied by the behavior of the parties. Transfers of copyright ownership, including exclusive licenses, may and should be recorded in the U.S. Copyright Office. (Information on recording transfers is available on the Office's web site.) While recording is not required to make the grant effective, it offers important benefits, much like those obtained by recording a deed in a real estate transaction.

Copyright may also be licensed.^[90] Some jurisdictions may provide that certain classes of copyrighted works be made available under a prescribed statutory license (e.g. musical works in the United States used for radio broadcast or performance). This is also called a compulsory license, because under this scheme, anyone who wishes to copy a covered work does not need the permission of the copyright holder, but instead merely files the proper notice and pays a set fee established by statute (or by an agency decision under statutory guidance) for every copy made.^[92] Failure to follow the proper procedures would place the copier at risk of an infringement suit. Because of the difficulty of following every individual work, copyright collectives or collecting societies and performing rights organizations (such as ASCAP, BMI, and SESAC) have been formed to collect royalties for hundreds (thousands and more) works at once. Though this market solution bypasses the statutory license, the availability of the statutory fee still helps dictate the price per work collective rights organizations charge, driving it down to what avoidance of procedural hassle would justify.

Copyright licenses known as open or free licenses seek to grant several rights to licensees, either for a fee or not. Free in this context is not as much of a reference to price as it is to freedom. What constitutes free licensing has been characterised in a number of similar definitions, including by order of longevity the Free Software Definition, the Debian Free Software Guidelines, the Open Source Definition and the Definition of Free Cultural Works. Further refinements to these definitions have resulted in categories such as copyleft and permissive. Common examples of free licenses are the GNU General Public License, BSD licenses and some Creative Commons licenses.

Founded in 2001 by James Boyle, Lawrence Lessig, and Hal Abelson, the Creative Commons (CC) is a non-profit organization which aims to facilitate the legal sharing of creative works. To this end, the organization provides a number of generic copyright license options to the public, gratis. These licenses allow copyright holders to define conditions under which others may use a work and to specify what types of use are acceptable.^[93]

Terms of use have traditionally been negotiated on an individual basis between copyright holder and potential licensee. Therefore, a general CC license outlining which rights the copyright holder is willing to waive enables the general public to use such works more freely. Six general types of CC licenses are available (although some of them are not properly free per the above definitions and per Creative Commons' own advice). These are based upon copyright-holder stipulations such as whether they are willing to allow modifications to the work, whether they permit the creation of derivative works and whether they are willing to permit commercial use of the work. As of 2009^[update] approximately 130 million individuals had received such licenses.^[94]

Some sources are critical of particular aspects of the copyright system. This is known as a debate over copynorms. Particularly to the background of uploading content to internet platforms and the digital exchange of original work, there is discussion about the copyright aspects of downloading and streaming, the copyright aspects of hyperlinking and framing.

Concerns are often couched in the language of digital rights, digital freedom, database rights, open data or censorship.^[95][96][97] Discussions include Free Culture, a 2004 book by Lawrence Lessig. Lessig coined the term permission culture to describe a worst-case system. The documentaries Good Copy Bad Copy and RiP!: A Remix Manifesto discuss copyright. Some suggest an alternative compensation system. In Europe consumers are acting up against the rising costs of music, film and books, and as a result Pirate Parties have been created. Some groups reject copyright altogether, taking an anti-copyright stance. The perceived inability to enforce copyright online leads some to advocate ignoring legal statutes when on the web.

Copyright, like other intellectual property rights, is subject to a statutorily determined term. Once the term of a copyright has expired, the formerly copyrighted work enters the public domain and may be used or exploited by anyone without obtaining permission, and normally without payment. However, in paying public domain regimes the user may still have to pay royalties to the state or to an authors' association. Courts in common law countries, such as the United States and the United Kingdom, have rejected the doctrine of a common law copyright. Public domain works should not be confused with works that are publicly available. Works posted in the internet, for example, are publicly available, but are not generally in the public domain. Copying such works may therefore violate the author's copyright.
