Mauritius accedes to ARIPO Harare Protocol: Implications for Patents, Utility Models and Industrial Designs

Written By Louise Audhlam-Gardiner

The Republic of Mauritius has formally acceded to the “Harare Protocol on Patents and Industrial Designs”, which is administered by the African Regional Intellectual Property Organization (ARIPO).  The instrument of accession was deposited on 27 May 2025, and the Protocol will enter into force with respect to Mauritius on 27 August 2025.

Key Implications:

  • New Designatable State: From 27 August 2025, Mauritius will become the 21st  contracting state to the Harare Protocol.   Applicants will be able to designate Mauritius in ARIPO applications for patents, utility models, and industrial designs.

  • Extension of Existing Rights: Holders of pending ARIPO applications and existing registrations will have the opportunity to extend protection to Mauritius.

  • Direct Filing for Mauritian Applicants: Mauritian nationals and residents will be entitled to file applications directly with the ARIPO Office, streamlining access to regional IP protection.

  • Trade Marks Not Affected: It is important to note that Mauritius has not acceded to the Banjul Protocol, which governs trade marks under the ARIPO framework.  Trade mark protection in Mauritius remains governed by national procedures.

IP owners and applicants with interests in the African region should review their current and planned filings to consider designating Mauritius where appropriate, when this becomes possible.
