What patent means
A patent is a trade with the state.
You publish exactly how your invention works, in enough detail that somebody skilled in the field could build it. In return you get twenty years during which nobody else may make, import, sell or use it in Nigeria without your permission.
The invention has to be new, it has to involve an inventive step rather than an obvious tweak, and it has to be capable of industrial application. An improvement on an existing product can qualify, provided the improvement itself is new and not obvious.
After twenty years the protection ends and the invention belongs to everybody. That is the point of the bargain: temporary exclusivity in exchange for permanent disclosure.
How it is used
Patents matter to people making things. A manufacturer with a new process, an engineer with a device, an agritech business with a new machine, a pharmaceutical formulation.
The application goes to the Patents and Designs Registry under the Federal Ministry of Industry, Trade and Investment. It includes a specification describing the invention, claims setting out precisely what you are asking to own, drawings where they help, and the filing fee. A granted patent is then maintained by paying annual fees.
Once granted, the patent is property. It can be sold, and it can be licensed, which is how most inventors actually earn from one. A licensing agreement sets out who may use it, in what territory, for how long and on what royalty.
Applicants outside Nigeria commonly file through the international route and enter Nigeria from there, since Nigeria is party to the main international arrangements.
Key features
- Protects inventions: products and processes, not names, logos or creative works
- Requires novelty, an inventive step and industrial applicability
- Lasts twenty years from the filing date, subject to annual fees
- Granted by the Patents and Designs Registry in Abuja
- First to file wins, so the date of filing decides competing claims
- Can be assigned or licensed like any other property
How this works in Nigeria
Two features of the Nigerian system catch people out.
The first is that Nigeria operates a first to file system with no examination of whether the invention is genuinely new. The Registry checks that the paperwork is in order and grants the patent. Whether it should have been granted is tested later, in court, if somebody challenges it. So a Nigerian patent certificate is a starting position rather than a guarantee.
The second is that protection is territorial. A patent granted in Nigeria protects you in Nigeria. It does nothing in Ghana, the United Kingdom or anywhere else, and each territory has to be applied for separately or through an international filing.
Certain things cannot be patented at all, including plant and animal varieties and essentially biological processes for producing them, and inventions whose use would be contrary to public order or morality. Discoveries, scientific theories and mathematical methods are not inventions in the required sense either.
Patent vs trademark vs copyright vs industrial design
Four different rights, and choosing the wrong one wastes both the fee and the year.
A patent protects how something works. The mechanism, the process, the formulation.
A trademark protects what you call it. The brand name, the logo, the slogan that tells buyers the product came from you. It can be renewed forever.
Copyright protects an original creative work, and it arises automatically on creation. Books, music, film, code, photographs.
An industrial design protects how something looks. The shape and ornamentation of an article, rather than the way it functions.
One product can carry all four at once. A new blender might have a patented motor assembly, a registered design for its casing, a trademark on the brand name and copyright in the manual.
Limits and risks
The largest limitation is self inflicted and permanent. Publicly disclosing your invention before filing destroys novelty. Demonstrating it at a trade fair, posting it online, pitching it without a non disclosure agreement, or selling it, can all bar the application. File first, then talk.
Because Nigeria does not examine for novelty before granting, a patent can be granted and later revoked. Anyone with an interest can challenge it in court on the ground that the invention was not new or not inventive, and that risk sits with the holder for the life of the patent.
Enforcement is also on you. The Registry grants the right; it does not police it. Stopping an infringer means writing to them and, if necessary, suing them.
And patents lapse quietly. Miss the annual fees and the protection ends, whatever the certificate on your wall says.
Worth knowing
Sign a non disclosure agreement before you show your invention to a manufacturer, an investor or a potential partner, and file before any public demonstration. Novelty is the one thing you cannot get back once it is gone.
Questions people ask
What can be patented in Nigeria?
A new product or process that involves an inventive step and can be applied industrially. Improvements on existing inventions qualify if the improvement is itself new and not obvious. Plant and animal varieties, essentially biological processes, and inventions contrary to public order cannot be patented.
How long does a patent last in Nigeria?
Twenty years from the date of filing, provided the annual maintenance fees are paid. It cannot be renewed beyond that, and the invention then enters the public domain.
What is the difference between a patent and a trademark?
A patent protects how an invention works and lasts twenty years. A trademark protects a brand name or logo, lasts seven years initially and can be renewed for fourteen year periods indefinitely, so long as it stays in use.
Can I patent an idea?
No. An idea on its own is not patentable. It has to be worked out into a specific invention that can be described in enough detail for somebody skilled in the field to reproduce it.
Does a Nigerian patent protect me abroad?
No. Patent rights are territorial. A Nigerian patent covers Nigeria only, and protection elsewhere requires filing in each country or using an international filing route.
What happens if I show my invention before filing?
Public disclosure before filing can destroy the novelty your application depends on. Sign a non disclosure agreement before showing it to anybody, and file before any public demonstration or sale.
