A copyright provides its holder several exclusive rights to control the reproduction, import and export of a work of authorship (e.g., literary work, movie, music, painting, software, mask work, etc.) Copyrights are often held by a work's author, although, for reasons discussed below, they may often be held by a corporation. Copyright stands in contrast to other forms of intellectual property, such as patents, which grant a monopoly right to the use of an invention, because it is not a monopoly right to do something, merely a right to prevent others doing it.
Copyright covers the expression of the idea, not the idea itself (unlike a patent). So for example the idea of writing an article about copyright has been thought of before (in every legal textbook for 100 years) but that does not stop us writing this article. What we cannot do is copy a chunk of text out of one of those text books.
A copyright holder typically has exclusive rights:
Note that copyright law does not restrict resale of copies of works, provided those copies were made by or with the permission of the copyright holder. Thus it is legal, for example, to resell a book or a CD that you have purchased, provided you do not keep a copy for yourself. In the US this is known as the First Sale Doctrine, and was established in the US court system to clarify the legality of reselling books in used book stores. Elsewhere it has other names; in the United Kingdom it is known as "Exhaustion of rights" and is a principle which applies to other Intellectual property rights.
Subject to moral rights, copyright also does not prohibit the owner of a physical copy of a work from modifying, defacing, destroying, etc. the work, so long as this does not involve duplication.
Copyright also does not prohibit all forms of copying. The fair use and fair dealing doctrines allows limited copying of portions of a copyrighted work in, for example, criticism, satire, or educational settings. Copyrighted works may also be available for copying through a statutory compulsory license scheme or via a copyright collective or performing rights organisation.
Typically, works must meet minimal standards of originality in order to qualify for a copyright, and the copyright expires after a set period of time.
Different countries impose different tests, although generally the test is low; in the United Kingdom there has to be some 'skill, originality and work' which has gone into it. However, even fairly trivial amounts of these qualities are sufficient.
In the United States, the original owner of the copyright may be the employer of the actual author rather than the author himself if the work is a "work for hire". Again, this principle is widespread; in English Law the Copyright Designs and Patents 1988 provides that where a work in which copyright subsists is made by an employee in the course of his employement the copyright is automatically assigned to the employer.
Copyrights are generally enforced by the owner in a civil law court,
but there are also criminal infringement statutes. Criminal sanctions are generally aimed at serious counterfeiting activity.
In the United States, font design is not copyrightable, but it is patentable if novel enough. Stone and Lucida are the only two patented typefaces, and this may not hold up in court.
Europe used to have the same "can't copyright typefaces" laws as the United States, but Germany (in 1981) and the UK (in 1989) have passed laws making typeface designs copyrightable. The UK law is even retroactive (!), so designs produced before 1989 are also copyrighted, if the copyrights wouldn't have already expired (the German one is not retroactive).
Many European countries (and other countries as a result of the GATT Trade Related Intellectual Property or "TRIPs" agreement) further provide for moral rights in addition to copyrights possessed by authors, such as the right to have
their work acknowledged and not be disparaged. (Famously, the Monty Python team managed to use these rights to stop the Monty Python TV programme being shown in the US because the US TV station was putting so many adverts into the program the Monty Python team claimed that it was being ruined as a serious comedy programme.)
While copyright is normally assigned or licensed to the publisher, authors
generally retain their moral rights (although in some jurisdictions these can be excluded under contract). In most of Europe it is not possible for authors to assign their moral rights (unlike the copyright itself, which is regarded as an item of property which can be sold, licensed, lent, mortgaged or given like any other property). They can agree not to enforce them (and such terms are very common in contracts in Europe). There may also be a requirement for the author to 'assert' these moral rights before they can be enforced. In many books, for example, this is done on a page near the beginning, in amongst the British Library/Library of Congress data.
Some European countries also provide for artist resale rights, which mean
that artists are entitled to a portion of the appreciation of the value of
their work each time it is sold. These rights are granted on the background of a different tradition, which granted droits d'auteur rather than copyright also granting all creators various moral rights beyond the economic rights recognized in most copyright jurisdictions. (see also parallel importation.)
Main article: History of copyright
While governments had previously granted monopoly rights to publishers
to sell printed works, the modern concept of copyright originated in 1710
with the British Statute of Anne.
This statute first recognized that authors, rather than publishers, should be
the primary beneficiary of such laws, and it included protections for consumers
of printed work ensuring that publishers could not control their use after
sale.
It also limited the duration of such exclusive rights to 28 years, after
which all works would pass into the public domain.
The Berne Convention of 1886 first established the recognition of
copyrights between sovereign nations.
(Copyrights were also provided by the
Universal Copyright Convention of 1952, but that convention is today largely of historical interest.)
Under the Berne convention, copyright is granted automatically to creative
works; an author does not have to "register" or "apply for" a copyright.
As soon as the work is "fixed", that is, written or recorded on some
physical medium, its author is automatically granted all exclusive rights
to the work and any derivative works unless and until the author explicitly
disclaims them, or until the copyright expires.
Some think the current copyright system doesn't work in the Information society. The general problem is that the current (international) copyright system undermines its own goal (Boyle 1996, 142). The concept of public domain, needed as a pool for future creators, is far too often forgotten or repressed, due to the strong position of the concept of the romantic author, and selective blindness for the possibilities concerning copyright that the Internet and computers offer. Except for unlimited copying, it offers, as said, also new ways for marketing and, more important, the possibilities of code; much depends of course of how code is used (code can be used and is in most of the cases also used in a positive way), but in various cases it threatens not only the public domain in a serious way, but is also ignored when talking about "restoring the balance" which is said to be gravely disturbed by the so called unlimited copying possibilities the Internet creates. [1]
Others believe that irrespective of contemporary advances in technology, copyright has been and remains the fundamental way by which authors, sculptors, artists, musicians and others can fund the creation of new works. This view espouses that copyright is the only reason some valuable books and art would be created.
In the US in 2003, controversial changes implemented by the Sonny Bono Copyright Term Extension Act extending the length of copyright under U.S. copyright law by 20 years were constitutionally challenged unsuccessfully in the Supreme Court. The Court, in the case called Eldred v. Ashcroft, held inter alia that in placing existing and future copyrights in parity in the CTEA, Congress acted within its authority and did not transgress constitutional limitations.
Copyright law varies from country to country.
