ARIPO patent – selecting countries

If you are approaching the 31 month deadline of your PCT patent, it is time to consider filing an ARIPO regional patent. This will secure protection over a large swathe of Southern Africa. But which ARIPO member countries should you select?

ARIPO regional phase patent

An ARIPO patent covers the following countries:

  • Botswana
  • Gambia
  • Ghana
  • Kenya
  • Lesotho
  • Liberia
  • Malawi
  • Mozambique
  • Namibia
  • Rwanda
  • Sierra Leone
  • Sudan
  • Swaziland
  • Tanzania
  • Uganda
  • Zambia
  • Zimbabwe

For each designated country:

  • the filing fee of the ARIPO patent increases by US$75, and
  • each renewal fee of the ARIPO patent increases by US$40 to US$520 (depending on the year).

Note: The ARIPO examination fee can be reduced significantly by passing an amendment within 18 months following filing (and pre-examination) to reduce the number of claims to 10 or less. For each claim above 10, a surcharge of US$40 is payable.

The table below (based on 2013 data) is useful to select appropriate ARIPO member states:
