Cameroon Patents

OAPI

Cameroon Patents may only be filed through the OAPI union where a single application covers all member states. It is not possible to obtain national registration in Cameroon but penalties for infringements are the responsibility of Cameroon courts. Cameroon Patents are valid for 20 years from the filing date and annual renewal fees are payable from the first anniversary of the filing date. OAPI patent registration is available for PCT and non-PCT applications. OAPI is a member of the Paris Convention (International treaty for the protection of Industrial Property) and the PCT.

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.
