Nigeria

The Nigerian Registry of Trade Marks, Patents and Designs administers the nation's patent affairs. As Africa's most populous country and largest economy, Nigeria occupies an indispensable position in the African IP strategies of multinational corporations. The current Patents and Designs Act exclusively provides for invention patents with a 20-year term, with no provisions for a utility model system.

Similar to South Africa, Nigeria operates a classic depository patent system without substantive examination. Although the law stipulates that an invention must be new, result from inventive activity, and be capable of industrial application to be patentable, administrative practice dictates that the Registry only examines applications for formal compliance (such as the presence of statutory forms, a specification, and claims). Once formal requirements are satisfied, the Registry promptly issues a patent certificate, expressly stating that the patent is granted "at the risk of the patentee and without guarantee as to its validity." This system was designed primarily out of necessity, given the historical scarcity of local technical examination resources, aiming to lower the administrative barriers for registering innovations.

In the realm of judicial jurisdiction and enforcement, the Federal High Court of Nigeria holds exclusive first-instance jurisdiction over all disputes concerning patent validity and infringement. Because patents are not substantively examined prior to grant, the Federal High Court effectively acts as the ultimate de facto examiner during litigation. When an infringement action is brought, the defendant's primary strategy is invariably to petition the court to declare the patent invalid. It is important to note that because Nigeria's IP judicial system is still evolving and judges generally lack specialized technical backgrounds in science and engineering, adjudicating complex technological facts poses significant challenges. Consequently, after securing patent rights in Nigeria, multinational corporations often prefer leveraging non-litigious avenues—such as commercial negotiations, licensing agreements, and border/customs recordations—to deter potential infringers, thereby circumventing the protracted and often unpredictable nature of local judicial proceedings.
