The expression "limitations and exceptions to copyright" refers to situations in which the exclusive rights granted to authors (or their asignees) under copyright law do not apply. Some may question whether this usage of "limitations and exceptions", although it appears in some international treaties such as the World Trade Organization Agreement of 1994, is conceptually correct. In law, an exclusive right is the power or right to perform an action in relation to an object or other thing which others cannnot perform. ... The copyright symbol is used to give notice that a work is covered by copyright. ...

Some critics prefer to regard "limitations and exceptions" as "user rights"; that is, rather than cutting down or modifying some idealized form of copyright, user rights provide an essential balance to the rights of copyright (or other intellectual property rights) holders. The concept of user rights has been recognized by courts such as the Canadian Supreme Court in CCH Canadian Ltd v. Law Society of Upper Canada 2004 SCC 13 [1], which classed "fair dealing" (referred to below) as such a user right. The use of "limitations and exceptions" in this entry should be therefore read subject to this caution.

Two important examples of limitations and exceptions to copyright are the fair use doctrine found in the United States, and the fair dealing doctrine found in many other common law countries. Other more fundamental boundaries of copyright are caused by thresholds of originality (below which objects cease to be copyrightable), the idea-expression dichotomy, the public domain and the effect of Crown copyright. These might be interpreted as defining copyright, rather than being "limitations" or "exceptions" to it. The fair use doctrine is an aspect of United States copyright law that provides for the licit, non-licensed citation or incorporation of copyrighted material in another authors work under a four-factor balancing test. ...

The scope of copyright limitations and exceptions is currently a subject of significant controversy within various nations, largely due to the impact of digital technology, and the enactment of anti-circumvention rules in response to the WIPO Copyright Treaty. Defenders of copyright exemptions fear that DRM technology will massively reduce the scope of important exceptions. Their opponents believe that if existing exemptions are allowed to continue, they will necessarily allow huge amounts of private copying and/or piracy-- if consumers can make a copy of a CD for their car, they can give MP3s to everyone. This article or section should be merged with Anti_circumvention The anti_circumventing rules were implemented in European Directive 2001/29/EC of the European Parliament and of the council of May 22, 2001 on the harmonisation of certain aspects of copyright and related rights in the information society. ...

Limitations and exceptions are also the subject of significant regulation by international treaties. These treaties have harmonized the exclusive rights which must be provided by copyright laws, and the Berne three-step test operates to constrain the kinds of copyright exceptions and limitations which individual nations can enact. In international law, harmonisation refers to the process by which different states adopt the same laws. ... The Berne three-step test is a set of constraints on the limitations and exceptions to exclusive rights under national copyright laws. ...

On the other hand, international copyright treaties place almost no requirements on national governments to provide exemptions from exclusive rights (one notable exception to this is Article 10(1) of the Berne Convention, which guarantees a limited right to make quotations from copyrighted works).*[2] The Berne Convention for the Protection of Literary and Artistic Works, sometimes called the Berne Union or Berne Convention, adopted at Berne in 1986, first established the recognition of copyrights between sovereign nations. ...
