Registering A Patent in the AIPO & ARIPO Intellectual Property Areas

Registering A Patent in the AIPO & ARIPO Intellectual Property Areas


Basically, a patent is a title granted by an intellectual property (patent) office for the protection of an invention, which is an idea which permits a specific problem in the field of technology to be solved in practice. An invention may consist in or relate to a product, a process or to a use thereof.

The title granted for the protection of an invention is subject to the patentability of the invention, that is, to the three cumulative criteria that the invention be new (novelty), involve an inventive step (non-obviousness), and that it be industrially applicable.

The invention which forms the subject matter of the patent may not fall in the class of non-patentable subject matters such as discoveries, scientific theories, mathematical methods, inventions whose use is contrary to public policy, inventions relating to plant varieties (protected under the law of new plant varieties), animal species, schemes, rules or methods for doing business, medical treatment methods, mere presentations of information, works of an exclusively ornamental nature (protected under the law of industrial designs), computer programs and databases (protected under copyright law), literary, architectural and artistic works or any other aesthetic creation (protected under copyright law, etc.).

Patent law protects only inventions which meet the three criteria listed above (novelty, inventive step and industrial applicability) and which are not in the class of non-patentable subject matters, as mentioned above. This does not, however, mean that non-patentable original ideas are not protected by intellectual property law altogether. Many intellectual property rights which are non-patentable subject matters may be protected either as utility models, industrial designs, trade or service marks, trade names, integrated circuits, geographical indications, new plant varieties, copyrights, etc., which are not the subject of this article. The term of protection of patents is generally twenty (20) years, provided that maintenance (annuities) fees are paid by the anniversary date of the patent. It is also important to note that patent rights are territorial, that is, they are protected strictly within the territories in which they have been registered. Patent protection within the AIPO and ARIPO area will afford protection strictly within the thirty five (35) members states of these African countries.

I – Direct Application to AIPO

The AIPO (the African Intellectual Property Organisation) comprises the following seventeen (17) member states: Benin, Burkina Faso, Cameroon, Central African Republic, Comoros Islands, Cote d’Ivoire, Gabon, Guinea-Conakry, Guinea-Bissau, Equatorial Guinea, Mali, Mauritania, Niger, Senegal, Tchad and Togo.  The OAPI zone is a market of 183 million consumers.

The AIPO serves as the national office for each of the 17 member states, meaning that applicants do not have to lodge patent applications in each of the seventeen (17) member states. A single application is lodged with the Organisation (regional office) which examines the application and issues an invention patent which is valid in all seventeen (17) member states. This is a fundamental difference between the AIPO patent system and the ARIPO patent system, as we shall see below.

Where there is a priority claim, the patent applicant is requested to provide documents to that effect within six (06) months from the date of filing of the application for the registration of the patent. While nationals or residents of one of the seventeen (17) member states of the AIPO may directly file their applications for the registration of their patents (inventions) without using the services of licensed patent agents/attorney, foreigners are obliged to use the services of these licensed IP professionals to file their patent applications with the regional office.

1 – Patent Filing Requirements

The information and documents required for this includes:

  • Filled application form 101

  • a descriptive abstract of the object of the invention.
  • Proof of priority or priority documents in English or French.
  • Priority assignment document (where the applicants are not identical).

II – Direct Application to ARIPO

The African Regional Intellectual Property Organisation (ARIPO) zone which is a similar regional intellectual property organisation regroups 19 member states mostly in North-East, East, West & Southern Africa, 18 of which are members of the Harare Protocol (Botswana, Eswatini, Gambia, Ghana, Kenya, Lesotho, Liberia, Malawi, Mozambique, Namibia, Rwanda, Sao Tome & Principe, Sierra Leone, Somalia, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe). ARIPO’s consumer population is 166 million large. The seat of the organisation is in Harare, Zimbabwe.

Contrary to AIPO, although the ARIPO is the national office of all nineteen member states, patent applications have to be communicated by the regional office to each member state for their written objection, where applicable, within six (06) months. Otherwise, the regional office proceeds to issue the right/title in respect to those designated states from whom no written objection was received.
