Copyright protection generally means that certain uses of a work are lawful only if they are done with the authorization of the owner of the copyright. The most typical are the following:
- copying or reproducing a work
- performing a work in public
- making a sound recording of a work
- making a motion picture of a work
- broadcasting a work
- translating a work
- adapting a work
Under certain national laws, some of these rights, which are referred to, as "economic rights'" are not exclusive rights of authorization but in specific cases, merely rights to remuneration. Some strictly determined uses (for example quotations or the use of works by way of illustration for teaching) are completely free, that is, they require neither authorization of, nor remuneration for, the owner of the copyright. This practice is described as
In addition to economic rights, authors enjoy "moral rights" on the basis of which they have the right to claim their authorship and require that their names be indicated on the copies of the work and in connection with other uses thereof. They also have the right to oppose the mutilation or deformation of their creations.
The owner of a copyright may usually transfer his right or may license certain uses of his work. Moral rights are generally inalienable and remain with the creator even after he has transferred his economic rights, although the author may waive their exercise.
Furthermore there exist rights related to copyright that are referred to as "neighboring rights". In general there are three kinds of neighboring rights: 1) the rights of performing artists in their performances, 2) the rights of producers of phonograms in their phonograms, and 3) the rights of broadcasting organizations in their radio and television programs. Neighboring rights attempt to protect those who assist intellectual creators to communicate their message and to disseminate their works to the public at large.
