°Members of African Intellectual Property Organization (OAPI) regional patent system. Only regional patent protection is available for OAPI member states. A designation of any state is an indication that all OAPI states have been designated.

°°Members of European Patent Convention (EPC) regional patent system. Either national patents or European patents for member States are available through PCT, except for Belgium, Cyprus, France, Greece, Ireland, Italy, > Latvia, Malta, < Monaco, Netherlands, and Slovenia, for which only European patents are available if the PCT is used.

The following states are members of African Regional Intellectual Property Organization (ARIPO) regional patent system and are Contracting States of both the Harare Protocol and the PCT: (4) Malawi, (34) Sudan, (68) Kenya, (73) Swaziland, (75) Uganda, (81) Lesotho, (89) Ghana, (90) Zimbabwe, (91) Sierra Leone, (93) Gambia, (103) United Republic of Tanzania, (107) Mozambique, (114) Zambia, (122) Botswana, and (123) Namibia. Note that with the accession of Botswana to the PCT, all 14 States party to the Harare Protocol are now also Contracting States of the PCT. State (73) Swaziland can only be designated for the purposes of an ARIPO patent and not for the purposes of a national patent. All other PCT Contracting States which are also party to the Harare Protocol can be designated either for a national or an ARIPO patent, or both a national and an ARIPO patent.

The following states are members of the Eurasian Patent Organization (EAPO) regional patent system: (15) Russian Federation, (57) Kazakhstan, (58) Belarus, (65) Kyrgyzstan, (66) Republic of Moldova, (67) Tajikistan, (70) Armenia, (78) Turkmenistan, and (82) Azerbaijan. All PCT Contracting States which are also party to the Eurasian Patent Convention can be designated either for a national or a Eurasian patent, or both a national and a Eurasian patent. Note, however, that it is not possible to designate only some of these States for a Eurasian patent and that any designation of one or more States for a Eurasian patent will be treated as a designation of all the States which are party to both the Convention and the PCT for a Eurasian patent.

°Members of African Intellectual Property Organization (OAPI) regional patent system. Only regional patent protection is available for OAPI member states. A designation of any state is an indication that all OAPI states have been designated.
°°Members of European Patent Convention (EPC) regional patent system. Either national patents or European patents for member States are available through PCT, except for Belgium, Cyprus, France, Greece, Ireland, Italy, > Latvia, Malta, < Monaco, Netherlands, and Slovenia, for which only European patents are available if the PCT is used.
The following states are members of African Regional Intellectual Property Organization (ARIPO) regional patent system and are Contracting States of both the Harare Protocol and the PCT: (4) Malawi, (34) Sudan, (68) Kenya, (73) Swaziland, (75) Uganda, (81) Lesotho, (89) Ghana, (90) Zimbabwe, (91) Sierra Leone, (93) Gambia, (103) United Republic of Tanzania, (107) Mozambique, (114) Zambia, (122) Botswana, and (123) Namibia. Note that with the accession of Botswana to the PCT, all 14 States party to the Harare Protocol are now also Contracting States of the PCT. State (73) Swaziland can only be designated for the purposes of an ARIPO patent and not for the purposes of a national patent. All other PCT Contracting States which are also party to the Harare Protocol can be designated either for a national or an ARIPO patent, or both a national and an ARIPO patent.
The following states are members of the Eurasian Patent Organization (EAPO) regional patent system: (15) Russian Federation, (57) Kazakhstan, (58) Belarus, (65) Kyrgyzstan, (66) Republic of Moldova, (67) Tajikistan, (70) Armenia, (78) Turkmenistan, and (82) Azerbaijan. All PCT Contracting States which are also party to the Eurasian Patent Convention can be designated either for a national or a Eurasian patent, or both a national and a Eurasian patent. Note, however, that it is not possible to designate only some of these States for a Eurasian patent and that any designation of one or more States for a Eurasian patent will be treated as a designation of all the States which are party to both the Convention and the PCT for a Eurasian patent.
