What know-how means
Know-how is the working knowledge that makes a process actually produce a result.
It is the temperature and the timing that turn a formula into a product. The sequence of operations that halves waste. The supplier contacts and the tolerances learned over ten years. The configuration that makes a system perform. None of it is written in the patent, and much of it is not written anywhere.
It has no registration. There is no know-how office and no certificate. It exists as long as it is not generally known, and it is protected by confidentiality obligations and by contract.
In practice know-how and trade secrets overlap heavily, and the terms are often used together. Where they are distinguished, know-how tends to describe technical and operational knowledge, while trade secret is the broader legal concept covering any confidential commercially valuable information, including customer lists and pricing.
How it is used
Know-how is transferred rather than sold, and it is transferred through people and documents.
A licence of know-how typically accompanies a licence of registered rights. A patent tells the licensee what the invention is. The know-how tells them how to actually make it work at scale, and without it the patent is often unusable.
A technology transfer agreement covers the technical documentation to be supplied, training of the licensee's staff, ongoing technical assistance, confidentiality obligations, restrictions on onward disclosure, what happens on termination, and the fee, which may be a lump sum, a royalty, or both.
Franchising works the same way. The operating manual, the training and the systems are know-how, and they are usually worth more to a franchisee than the brand alone.
Within a business, the protection is practical. Confidentiality clauses in employment contracts, restricting access to those who need it, documenting processes so they survive the departure of the person who developed them, and exit procedures that recover devices and files.
Key features
- Practical technical or operational knowledge that is not generally known
- Cannot be registered, and has no expiry as long as it stays confidential
- Protected by confidentiality obligations and by contract
- Commonly licensed alongside patents and in franchising
- Transferred through documentation, training and technical assistance
- Lost permanently once it becomes public
How this works in Nigeria
Foreign technology transfer carries a registration requirement that catches businesses out.
Agreements involving the transfer of foreign technology to Nigerian parties are expected to be registered with the National Office for Technology Acquisition and Promotion. Registration affects the ability to remit fees and royalties abroad through official channels, so a Nigerian licensee paying a foreign licensor without it can find the payments difficult to make formally.
That is not a formality to leave until the first invoice. It should be dealt with as the agreement is signed.
Domestically, know-how protection rests on confidentiality, and Nigerian courts enforce confidentiality obligations and the equitable duty of confidence. What they will not enforce is an unreasonable restraint on a departing employee's ability to earn, so protection is stronger where it is framed around specific confidential information rather than around a broad ban on working in the sector.
The practical Nigerian risk is undocumented know-how walking out of the door. Where the process exists only in one person's head, their departure takes it, and no contract recovers what was never written down.
Know-how vs patent vs trade secret
Three ways of holding technical value, with different mechanics.
A patent is registered and published. You disclose exactly how the invention works and receive twenty years of exclusivity enforceable against anybody. After that it belongs to everybody.
Know-how is unregistered and unpublished. It has no expiry and no exclusivity, only confidentiality. Somebody who works it out independently owes you nothing.
A trade secret is the broader legal concept covering confidential commercially valuable information of any kind, including commercial information such as customer lists and pricing as well as technical knowledge.
In a real technology deal all three appear together: a patent over the invention, know-how covering how to operate it, and confidentiality obligations protecting both. A licensee who takes the patent without the know-how frequently cannot make the thing work.
Limits and risks
Know-how gives no monopoly. A competitor who develops the same method independently, or reverse engineers it lawfully, is free to use it.
It is also fragile. One disclosure, in a pitch, a paper or a departing employee's next job, and the value is gone permanently.
Proof is difficult. Establishing that a former employee used your specific process rather than their general experience is genuinely hard, and courts distinguish between confidential information and the skill somebody acquired doing the job.
And unwritten know-how cannot be protected at all. If it exists only in somebody's head, the business does not really own it, and no agreement changes that.
Worth knowing
Document the process while the person who developed it is still with you, and register any foreign technology transfer agreement with NOTAP as it is signed. Nigerian businesses lose know-how twice over: once because it was never written down, and once because the licensor could not be paid.
Questions people ask
What is know-how?
Practical technical or operational knowledge that makes a process work, such as methods, settings and accumulated experience. It cannot be registered and is protected by confidentiality and contract.
What is the difference between know-how and a patent?
A patent is registered and published, giving twenty years of exclusivity in exchange for disclosure. Know-how is unregistered and confidential, lasts as long as it stays secret, and gives no protection against independent development.
How is know-how protected?
By confidentiality obligations in employment contracts and non disclosure agreements, by restricting access to those who need it, by documenting the process, and by exit procedures that recover devices and files.
Do I need to register a technology transfer agreement in Nigeria?
Agreements transferring foreign technology to Nigerian parties are expected to be registered with NOTAP. Registration affects the ability to remit fees and royalties abroad through official channels, so deal with it when the agreement is signed.
Can a former employee use what they learned?
They can use the general skill and experience they acquired. What they cannot use is specific confidential information belonging to the employer. Courts draw that line, and it is why narrow, specific confidentiality clauses work better than broad ones.
What is the difference between know-how and a trade secret?
Know-how usually describes technical and operational knowledge. Trade secret is the broader concept covering any confidential commercially valuable information, including customer lists and pricing.
