Patent Registration in Nigeria: A Practical Guide for Inventors

A patent gives an inventor the exclusive right to exploit an invention for a limited period — and in Nigeria, under the Patents and Designs Act, that right belongs to the first to file, not the first to invent. Understanding the process early is the difference between owning your invention and watching someone else file it first.

What Is Patentable

• —A product or process that is new
• —Involves an inventive step — not obvious to someone skilled in the field
• —Capable of industrial application

Not everything is patentable. Discoveries, scientific theories, mathematical methods, and inventions contrary to public policy or morality are excluded. Computer programs as such also face barriers, though software embedded in a patentable process can qualify.

Why Register

• —Exclusive right to make, use and sell the invention in Nigeria
• —Licensing and royalty income from third parties
• —A deterrent against copycats and counterfeiters
• —A priority date that protects you against later filings

The Registration Process

• —Conduct a patentability search to confirm your invention is new
• —Prepare the specification — a full description and precise claims
• —File at the Trademarks, Patents and Designs Registry
• —Substantive examination of the application
• —Grant and sealing of the patent

Duration and Renewals

A Nigerian patent lasts twenty years from the date of filing, subject to the payment of renewal fees from the fifth year. Missing a renewal window can lapse the patent entirely — renewal dates belong on a calendar, not a memory.

The Priority Date Matters

Nigeria operates a first-to-file system. If you disclose your invention publicly before filing — at an exhibition, in a brochure, even to a potential investor — you may destroy its novelty and your own chance of a patent. File first, disclose later, and document every stage of development.

In a first-to-file world, the pen that matters is the one that signs the application.

Enforcing Your Patent

• —Infringement actions for unauthorised exploitation
• —Injunctions to stop ongoing infringement
• —Damages or an account of the infringer's profits
• —Licensing agreements to commercialise the invention

Common Mistakes

• —Public disclosure before filing
• —Weakly drafted claims that are easy to design around
• —Filing late — or watching a competitor file first
• —Missing renewal fees and letting the patent lapse
