Buenos Aires Convention

The Buenos Aires Convention is a copyright treaty signed at Buenos Aires on 1910-04-11 which provides for the mutual recognition of copyrights where the work carries a notice containing a statement of reservation of rights (Art. 3). This was commonly done by the use of the phrase "All rights reserved" (Spanish "Todos los derechos reservados", Portuguese "Todos os direitos reservados") next to the copyright notice. Copyright protection under the Convention is granted for the shorter of the terms of the protecting country and the source country of the work ("rule of the shorter term", Arts. 6, 7). The rather vague nature of the requirement for a statement of reservation led to the development of longer and more legalistic wordings, which have persisted despite the developments in international copyright law.
