Trade Secret

The protection is built out of contracts and practice rather than out of a registry.

Employment contracts carry confidentiality clauses covering what an employee may not disclose during and after employment. Non disclosure agreements cover conversations with potential partners, investors, manufacturers and contractors. Supplier and contractor agreements carry the same obligations down the chain. Non compete clauses, within reasonable limits, restrict a departing employee from immediately using what they learned for a competitor.

The practical measures matter as much as the documents. Restricting access to the people who need it, marking documents as confidential, using passwords and access controls, running exit interviews and collecting company devices and files when somebody leaves.

Businesses that do this well can act quickly when something walks out of the door. Businesses that did none of it discover their most valuable information was never legally protected at all.

Nigeria has no standalone trade secrets statute. Protection comes from two directions.

The first is contract. A confidentiality clause or a non disclosure agreement is enforceable like any other contract, and courts will award damages and grant injunctions restraining further disclosure.

The second is the equitable duty of confidence, which can apply even without a written agreement where information of a confidential nature was disclosed in circumstances importing an obligation of confidence and was then misused. Employees also owe duties of fidelity to their employer during employment.

Restrictive covenants against former employees are enforceable only within reason. Nigerian courts, following the common law approach, will not uphold a restraint that goes beyond protecting a legitimate business interest, so a non compete of unlimited duration across the whole country is likely to fail while a narrow one protecting genuine confidential information may hold.

Enforcement is the weak point, as it is for intellectual property generally. Injunctions are available but move at the pace of the court, and information that has already spread cannot be recalled.

The same invention can go either way, and the choice is permanent.

A patent gives you twenty years of exclusivity, enforceable against anybody, in exchange for publishing exactly how the invention works. After twenty years everybody may use it.

A trade secret gives you protection for as long as you can keep it quiet, potentially forever, but only against people who obtained it improperly. Somebody who independently invents the same thing, or reverse engineers your product lawfully, owes you nothing.

So the question is whether the thing can be kept secret at all. A process that happens inside your factory and cannot be deduced from the product is a good candidate for secrecy. A mechanism that is visible the moment somebody opens the device is not, and should be patented.

The famous soft drink formula is the standard example of secrecy outlasting any patent. Most inventions are not like that, and disclosure through the product itself is the usual reality.

The protection ends the moment the secret does. Once information is public, no contract restores it, and the remedy is damages against whoever leaked it rather than getting the advantage back.

It also gives no protection against honest competitors. Independent development and lawful reverse engineering are both permitted, which means a competitor can arrive at the same result and use it freely.

Enforcement depends on proof, and proving that a departing employee used your customer list rather than their own memory and contacts is genuinely difficult.

And overreaching backfires. Employers who write sweeping confidentiality and non compete clauses covering everything an employee ever saw often find the clause unenforceable, leaving them with less protection than a narrower one would have given.
