PATENT REGISTRATIONS

Patent protection is obtainable via a national filing. Liberia is a member of the International Convention and of PCT.

The requirements for filing a non-PCT application in Liberia are as follows:

(a) Declaration and Power of Attorney (notarized and legalized up to Liberian Consular level);
(b) Deed of Assignment if the inventor(s) is/are not the applicant(s) (notarized and legalized up to Liberian Consular level);
(c) A copy of the specification (including claims, drawings, and abstract) in English; and
(d) A certified copy of the priority application and, if necessary, a certified translation into English thereof.

Please note that the documents listed under item (c) are required on the day of filing. Items (a), (b), and (c) can be late lodged subsequent to the filing date. However, for a surcharge of about US$ 150.00 we are able to have your instructional letter legalized with the Justice of Peace in Liberia which shall be accepted into evidence by the Registrar in lieu of items (a) and (b).
