Zambia Patents

Patent & Design Protection

Zambia patents have a duration of 20 years from date of filing. Annual renewal fees are payable from the third anniversary of the filing date. Zambia is a member of PCT and the Paris Convention (International treaty for the protection of Industrial Property). Zambia patents have a requirement of absolute novelty.

PCT National Phase entries provide a unified procedure for filing patent applications to protect intellectual property in each of its contracting states. A patent application filed under the PCT is called an international application, or PCT application. 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.
