ARIPO vs OAPI is the split that decides which regional filing route, if any, actually reaches a given African country, and Kenya sits firmly on the ARIPO side of that line. Foreign counsel who assume Africa has one regional IP system, the way the EU has one trademark office, run into trouble fast: there are two systems, they work on opposite principles, and a filing strategy built for one will not transfer to the other.
Two Organizations, Two Different Ideas of “Regional”
The African Regional Intellectual Property Organization (ARIPO) was established by the Lusaka Agreement of 1976 and is headquartered in Harare. Its French-speaking counterpart, the Organisation Africaine de la Propriété Intellectuelle (OAPI), was established one year later by the Bangui Agreement of 1977 and is headquartered in Yaoundé. Both grew out of the same colonial-era language divide: ARIPO’s membership is drawn from Anglophone (and a handful of Lusophone) African states, while OAPI’s seventeen members are almost entirely Francophone. Kenya, as an ARIPO member, is on the Anglophone side of that split by both geography and legal tradition.
OAPI Is Unitary: One Filing, No Choice of Country
OAPI has seventeen members: 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. None of them run separate national trademark or patent registries. Under the Bangui Agreement, a single OAPI application is automatically effective in all seventeen states at once. An applicant cannot designate only three of them, and cannot file nationally in any of them as an alternative. Joining OAPI means a member state gives up its own national IP registry in favor of the regional one. That is what “unitary” means in practice: OAPI is the only route in, for every one of its members.
ARIPO Is a Menu, Not a Merger
ARIPO works on the opposite principle. It administers separate protocols that member states join individually, and an applicant designates only the specific member states it wants covered, exactly like the Madrid Protocol does for trademarks worldwide. The Harare Protocol covers patents, utility models, and industrial designs. The Banjul Protocol covers marks. The Arusha Protocol covers plant varieties, and the Swakopmund Protocol covers traditional knowledge and folklore. Crucially, ARIPO membership and protocol ratification are not the same thing, and protocol ratification and domestic enforceability are not the same thing either. A country can belong to ARIPO without having joined the Banjul Protocol at all. Kenya is the clearest illustration: it ratified the Harare Protocol, so an ARIPO patent or industrial design filing can designate Kenya, but it never ratified the Banjul Protocol, so ARIPO cannot be used to obtain a trademark in Kenya under any circumstances. A foreign trademark owner has to file directly with the Kenya Industrial Property Institute or designate Kenya through the Madrid Protocol instead.
Even Ratification Does Not Guarantee It Works
A September 2025 ruling from Tanzania’s Court of Appeal is worth knowing about here, because it shows the ARIPO system has a second layer of risk beyond simple non-ratification. Tanzania had ratified the Banjul Protocol back in 1999 and, unlike Kenya, appeared on paper to be a full member of the trademark system. In Lakairo Industries Group Co. Limited and Others v Kenafrica Industries Limited and Others, Civil Appeal No. 593 of 2022, the Court of Appeal held that Tanzania had never actually incorporated the Banjul Protocol into its own domestic law, so ARIPO trademark registrations designating Tanzania carried no legal force there regardless of the ratification. ARIPO itself confirmed the fallout in an official notice a few weeks later: Tanzania has been ineligible for Banjul designation since 23 October 2025, until domestication catches up with ratification. For a system built entirely on the idea that a single regional filing works across borders, this is a reminder that “ratified” and “enforceable” are two separate questions, and both need checking country by country, not assumed from a membership list.
ARIPO vs OAPI: What the Split Means for Filing Strategy
The practical rule for anyone filing across this region is to treat ARIPO and OAPI as two separate systems that never overlap, and to check three things before relying on either for a given country: whether the country is an ARIPO or OAPI member at all, whether it has ratified the specific protocol the right in question falls under, and, increasingly relevant after Tanzania, whether that ratification has actually been given effect in domestic law. For Kenya specifically, that means Harare-Protocol filings (patents, utility models, industrial designs) can reach it through ARIPO, but trademark filings cannot, and must go through KIPI directly or the Madrid Protocol. Getting the ARIPO vs OAPI distinction right at the outset avoids a wasted filing in the wrong system entirely.
How We Can Help
Clay & Associates Advocates advises foreign and regional counsel on where a given IP right can actually be obtained and enforced across Kenya and the wider East African market, including which regional system, if any, reaches the jurisdiction in question. Our guide to protecting a brand in Kenya covers the direct-filing and Madrid Protocol routes into Kenya in more detail, and our piece on local agent requirements in Kenya sets out what changes once a right does reach Kenyan territory.

Frequently asked questions
Can an OAPI filing designate Kenya?
No. Kenya is not an OAPI member, and OAPI membership and ARIPO membership are mutually exclusive among African states; a country belongs to one system or the other, not both.
Is Kenya an ARIPO member?
Yes, and it has ratified the Harare Protocol covering patents, utility models, and industrial designs. It has not ratified the Banjul Protocol covering trademarks, so ARIPO cannot be used to obtain a Kenyan trademark.
Why can OAPI members not file national applications instead?
Because OAPI is unitary: joining OAPI means a state gives up its own national IP registry in that field entirely, so the regional filing is the only filing that exists. This is the sharpest practical difference in the ARIPO vs OAPI comparison.
Does ARIPO ratification guarantee a right is enforceable in that country?
Not necessarily. Tanzania’s 2025 Court of Appeal ruling confirmed that ratifying a protocol is not the same as giving it effect in domestic law, and ARIPO trademark filings designating Tanzania are currently ineligible as a direct result.
