To obtain trademark protection and recognition in Guinea-Bissau, the mark must be registered through OAPI (Organisation Africaine de la Propriété Intellectuelle). A single registration with OAPI grants protection in all 17 member states: Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Comoros, Republic of the Congo, Equatorial Guinea, Gabon, Guinea, Guinea-Bissau, Ivory Coast (Côte d'Ivoire), Mali, Mauritania, Niger, Senegal and Togo.
OAPI is also a member state of the Madrid Protocol, so an international registration can be extended to Guinea-Bissau via the Madrid System.
If you register a combined trademark (word + logo) through OAPI, the exclusive right is limited to the exact configuration filed. If you want to use and protect the word and figurative elements separately, you should file separate trademarks for each element.
