Organisation Africaine de la Proprie Intellectuelle

Entering into force on 1st January 1964, OAPI covers the following French-speaking African countries:

Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Congo, Djibouti, Gabon, Guinea, Ivory Coast, Mali, Mauritania, Niger, Senegal, Togo and Guinea-Bissau.

A feature of the OAPI is that the OAPI patent is a single patent which extends to each member country. There is a single Patent Law that is applied by Courts of each country. As such there is no so-called national phase or national patent as is the case of other regional systems, but it is not possible to restrict designated states.  In OAPI applications all of the above countries are automatically designated. After grant there is no need to file translations or take any other local action. Annual renewal fees are payable direct to the OAPI Patent Office.
