São Tomé and Príncipe Patents

Patent & Design Protection

São Tomé and Príncipe Patents have a duration of 20 years from date of filing. São Tomé and Príncipe is a member of PCT and the Paris Convention. PCT National Phase entries provide a unified procedure for filing patent applications to protect intellectual property in each of its contracting states.

The Patent Cooperation Treaty  (PCT) is an international patent law treaty that provides a unified procedure for filing patent applications to protect inventions in all of its contracting states. A single filing of an international application is made with a Receiving Office (RO) in one language. It then results in a search performed by an International Searching Authority (ISA), accompanied by a written opinion regarding the patentability of the invention, which is the subject of the application. The PCT National Phase entry essentially leads to a standard national or regional patent application, which may be granted or rejected according to applicable law, in each jurisdiction in which a patent is desired. 

São Tomé and Príncipe Patents may be filed through the ARIPO union where the applicant may file a single application designating the specific contracting states either directly at ARIPO or through a contracting state. The relevant protocol on Patents for ARIPO is the Harare Protocol, which authorises ARIPO to register Patents on behalf of Harare Protocol Contracting States.
