Kenya is a contracting state to the Patent Cooperation Treaty, and the Industrial Property Act, 2001 gives the Kenya Industrial Property Institute (KIPI) its role as receiving, designated and elected office for PCT purposes. An applicant who has filed a PCT international application designating Kenya still has to take a deliberate further step, entering the national phase, before KIPI will examine and potentially grant a patent or utility model. Missing the applicable deadline, or misunderstanding which of two available deadlines applies, is one of the more common and entirely avoidable ways an otherwise sound Kenyan filing strategy goes wrong.
The Deadline: 30 Months for Direct Entry, 31 for the ARIPO Route
Under WIPO’s PCT Applicant’s Guide, Kenya national chapter, the time limit for entering the Kenya national phase directly at KIPI is 30 months from the priority date, whether the applicant proceeds under PCT Article 22(1) or files a demand and proceeds under Article 39(1)(a). This is one of the more applicant-friendly deadlines in the PCT system; some designated offices, including several in Europe, apply 31 months. The position changes, however, if the applicant instead designates or elects Kenya through the ARIPO route under the Harare Protocol, since Kenya is a Harare Protocol member: WIPO’s time limit table then applies the ARIPO Office’s own 31-month deadline. An applicant weighing a direct KIPI filing against an ARIPO filing that includes Kenya among several designated states needs to track two different deadlines, not one, depending on the route chosen.
Missing the Deadline Is Not Necessarily Fatal, but Reinstatement Is Discretionary
KIPI does permit reinstatement of rights under PCT Rule 49.6 where the deadline is missed, applying an “unintentional” criterion. This is a genuine safety net, but it is not automatic: the Managing Director exercises discretion over whether the failure to meet the deadline was in fact unintentional, and a request for reinstatement, together with the prescribed fee, has to be made and justified. Treating reinstatement as a routine extension rather than a discretionary remedy of last resort is a mistake; the safer course is always to calendar and meet the original 30 or 31-month deadline.
What Must Be Filed, and in What Language
Kenya’s receiving office and national phase both operate in English. Where the international application was not filed or published in English, a translation covering the description, the claims (as amended, together with any Article 19 statement, if entering under Article 22), any text in the drawings, and the abstract must be furnished within the applicable deadline. Errors in that translation can later be corrected by reference back to the international application as filed, which gives some room to fix a translation mistake without losing the application, but the safer approach is to have the translation independently checked before the deadline rather than relying on that correction mechanism afterwards. Non-resident applicants must also appoint an agent who is a citizen of Kenya admitted to practise before KIPI, the same requirement discussed in our guide to local agent requirements for foreign IP applicants at KIPI, and applicants who want a utility model rather than a patent need to have indicated that choice in the international application itself, though conversion between the two remains possible later under section 83 of the Act.
Costs, as of the Current PCT Applicant’s Guide
As of the version of the PCT Applicant’s Guide applicable from 1 January 2026, KIPI’s national processing fee on entry is 3,000 Kenyan shillings (150 US dollars) for a patent application and 1,000 Kenyan shillings (50 US dollars) for a utility model application, with the first annual fee, due for the second year, set at 2,000 Kenyan shillings (300 US dollars) for patents. Fees are payable in US dollars where the person paying does not reside in Kenya and has no principal place of business there. These figures change from time to time and should be confirmed against the current Guide or with KIPI directly before a filing is finalised, but they give a realistic sense of the entry cost relative to the transmittal and international filing fees already paid at the international phase.
Common Pitfalls
The recurring problems are rarely exotic. Applicants miscalculate which of the 30 or 31-month deadlines applies because they have not fixed on a direct KIPI or ARIPO filing route early enough. Non-resident applicants file without appointing the mandatory citizen agent, triggering a formality invitation that costs time even where it does not ultimately cost the application. Translations are prepared quickly and cheaply late in the period rather than checked well before the deadline. And utility model applicants occasionally fail to indicate that election at the international phase, complicating what should have been a straightforward request.
How We Can Help
Clay & Associates Advocates advises applicants and instructing foreign counsel on PCT national phase entry in Kenya, from calendaring the correct deadline through to appointing local agents and managing translation and formality requirements. Our guide to industrial design registration in Kenya covers the separate route for designs, which the PCT system does not itself provide for.

Frequently asked questions
Is the Kenya national phase deadline 30 or 31 months?
30 months for direct entry at KIPI. If Kenya is instead designated through the ARIPO regional route, the applicable deadline becomes 31 months.
What happens if we miss the deadline?
KIPI allows reinstatement of rights under an “unintentional” standard, but this is discretionary and requires a justified request and fee, not an automatic extension.
Do we need a translation if our PCT application was filed in English?
No. A translation is only required where the international application was not filed or published in English.
Can we still get a utility model if we only requested a patent at the international phase?
Conversion between a patent application and a utility model application remains available at any time before grant or refusal under section 83 of the Industrial Property Act.
