Tunisia is a member to the Paris Convention for the Protection of Industrial Property signed in 1883 and has ratified the texts of the Paris Convention as revised in The Hague (1925), in London (1934) and in Stockholm (1967). As of April 9, 1988, Tunisia withdrew from the Madrid Agreement with the result that national applications should be filed in the country to secure protection of trademarks. Existing international registrations will continue to be in force till their respective expiry dates. Renewals of the international registration may be effected by filing national renewal applications. For the purposes of the registration of trademarks, the international classification of goods and services is followed in Tunisia. An application for registration may include goods or services in any number of classes of the international classification with the payment of additional fees to cover the additional classes.
