OAPI general info

The Organisation Africaine de la Propriété Intellectuelle, or OAPI (English: African Intellectual Property Organization), is a regional intellectual property organisation headquartered in Yaoundé, Cameroon. The organization was established by the Bangui Agreement of March 2, 1977, which was subsequently amended in 1999 and 2015 (Bamako). The protection of the types of intellectual property registered with OAPI is automatically valid in its 17 current member states: Benin, Burkina Faso, Cameroon, the Central African Republic, Chad, the Comoros, the Congo, Côte d'Ivoire, Equatorial Guinea, Gabon, Guinea, Guinea-Bissau, Mali, Mauritania, Niger, Senegal, and Togo.

OAPI registrations automatically extend to all member states. Upon joining OAPI, member states waive their right to national filing. Therefore, it is not possible to designate individual member states. Decisions issued by a national court of any member state on the provisions of OAPI law are binding on all other member states upon notification to the Organization.
