Copyright
A series of personal and patrimonial rights are within the Intellectual Property, which provides to the authors labor its full disposal and the exclusive right of its exploitation only with law limitation.
As you know, an Author is a person that creates any literary, artistic or scientific work. The Intellectual Property of mentioned labor belongs to the Author because of her/his creation and this condition lasts forever.
Despite the fact that Copyright protection operates from the right moment of creation, it is important to register the work as its evidence in case of lawsuit.
