The registration of works in intellectual property registries, before disseminating them, provides the creators (and to their owners) an ideal means of protection to prove their authorship and rights in case of controversy on the part of from a third party, to allow us to demonstrate that the work existed and that it was available before another person or entity.
The inscriptions in intellectual property registries operate, therefore, as juris presumptions tantum; that is, they are admitted as proof of authorship and rights, but they can be questioned and lose their effectiveness if, for example, an inscription of rights of previous date will be presented.
