Algeria is a member to the Paris Convention for the Protection of Industrial Property as of March 1, 1966 and a party to the Madrid Agreement concerning international registration of trademarks (Act of Stockholm of 1967) as from July 5, 1972. The international classification of goods and services for the purpose of registration of marks is followed in Algeria. An application may include goods and/or services in any number of classes against payment of an additional fee to cover the additional classes.
Once a trademark application is filed, the filing certificate indicating the filing number and the filing date is issued. Trademark applications are not examined as to their registrability against prior registrations. The certificate of registration is issued after completing all the filing requirements. Trademarks are published after the registration and there is no provision for filing opposition to the registration of a mark.
