Patents Laws in Senegal
Here’s an overview of patent laws in Senegal:
🏛️ Legal Framework
Patent law in Senegal is governed by the African Intellectual Property Organization (OAPI) Agreement.
Senegal is a member of OAPI, which provides a centralized patent system covering 17 member states in West and Central Africa, including Senegal.
The OAPI Bangui Agreement establishes the legal framework for patents, trademarks, and other IP rights across member countries.
📌 Patentability Criteria
To be patentable under the OAPI system (applicable in Senegal), an invention must be:
Novel: It must not be part of the prior art anywhere in the world before the filing date.
Involve an inventive step: The invention must not be obvious to a person skilled in the art.
Capable of industrial application: The invention can be made or used in any industry.
Not excluded: Discoveries, scientific theories, mathematical methods, plant or animal varieties, and certain methods (like medical or surgical methods) are excluded.
📝 Application Process
Filing the Application
Patent applications are filed with the OAPI Office headquartered in Yaoundé, Cameroon.
The application includes a description, claims, abstract, and drawings (if needed).
Official languages are French and English, but French is most commonly used.
Formal Examination
The OAPI Office checks the application for compliance with formal requirements.
Search Report
A search is conducted to assess novelty and inventive step.
Publication
Applications are published 18 months after the filing or priority date.
Substantive Examination

Grant or Refusal
If requirements are met, the patent is granted and published.
Otherwise, it is refused.
⏳ Duration and Maintenance
Patents granted through OAPI have a duration of 20 years from the filing date.
Annual maintenance fees are required to keep the patent in force.
🌍 Regional and International Protection

Senegalese applicants can also file under the Patent Cooperation Treaty (PCT) designating Senegal.
OAPI patents are enforceable in all member states, including Senegal.
⚖️ Enforcement
Patent enforcement is conducted through national courts of OAPI member states.
Remedies include injunctions, damages, and seizure or destruction of infringing products.
