Copyright - field of Intellectual Property - protects literary and artistic works. The copyright law has the purpose to protect intellectual creation expressed by any means or medium of expression. The protection includes only the form of expression of ideas, not the ideas themselves. Authorship has certain specific rights moral and economic rights. Moral rights - right of paternity and right of integrity, for example - allow the author to preserve the personal link between himself and his work. They remain with the author even after he has transferred his economic rights or the work has fallen into the public domain. Economic rights permit the author gain financial reward from the use of his works by others. Authorship has many forms of exploitation of his work like to authorize reproduction, distribution and public performance. Economic rights are not to be perpetual as moral rights. They are temporary considering the social function of the copyright and of the public interest in to develop the cultural heritage. In this work we intend to analyze the situations in whic after a certain perior of time and accomplishment of the legal conditions the intellectual work is transferred from the author to the public domain and consequently may be freely used by any interested party.
