The (Revised) Berne Convention
for the Protection of Literary and Artistic Works is a Contract
under international law that was adopted in Bern in 1886 and has since been revised several times for which reason it is known as the Revised Berne Convention
(RBÜ). The Berne Convention
provides that every Member
country shall recognise the protection of works by citizens of other Contract
signatories to the same extent as it recognises the protection of works of its own citizens (principle of national treatment).
