NDA for Licensing UK: Protecting Your IP Before You Licence It

Licensing your IP is one of the highest-value commercial transactions a UK business can enter into — but it requires revealing exactly what you are selling before any deal is done. A potential licensee needs to understand your patent, your software, your process or your brand well enough to evaluate whether they want to pay for the right to use it. And that means disclosing your most sensitive commercial information before any contract is signed.

Why licensing discussions need an NDA

In any IP licensing negotiation, the information you share is commercially valuable precisely because it is not public. A patent claim you intend to licence may be unregistered. A software platform may rely on proprietary algorithms that are trade secrets. A brand licensing deal reveals the royalty terms you are prepared to accept.

Without an NDA, a potential licensee can walk away from negotiations with a clear picture of your IP — and nothing legally prevents them from using that information to compete with you, recreate your product, or negotiate with your competitors.

The problem is acute in the early stages, when you are still establishing whether the other party is a viable licensee and before either party has committed to a deal. An NDA creates a binding confidentiality obligation from the first conversation, giving you legal recourse if the other party misuses what they learn.

What information to protect

The confidential information definition in a licensing NDA should name exactly what you are disclosing. Common categories in licensing contexts include:

• Patent claims and technical specifications: pending and granted patent claims, drawings and priority dates — particularly important before a patent is granted
• Proprietary software and source code: architecture, algorithms, APIs and technical documentation
• Trade secrets and know-how: manufacturing processes, formulations, yield data and operational methods that have value because they are not public
• Commercial terms: royalty rates, minimum commitments, territory rights and sub-licensing terms you are prepared to offer
• Financial information: revenue data, unit economics and valuation assumptions shared to support licensing negotiations
• Brand and marketing materials: brand guidelines, licensed designs and unreleased creative assets

A generic definition — "all information shared between the parties" — provides some protection but creates ambiguity about what is actually covered. In a licensing dispute, the court will consider whether the information was objectively confidential and whether the recipient understood it was received in confidence.

One-way or mutual NDA for licensing?

The structure of the NDA should reflect which party is actually sharing confidential information during the licensing discussion.

In most initial licensing conversations, the answer is clear: you are disclosing your IP, your commercial terms and your know-how to a potential licensee who is evaluating whether to buy the right to use it. Only one party is disclosing substantive confidential information — a one-way NDA (disclosing party) is the appropriate document.

A mutual NDA is appropriate where the potential licensee also shares confidential information during the process — for example, revealing their production capacity, existing customer relationships, integration architecture or competing IP as part of a structured licensing evaluation.

Using a mutual NDA when only one party discloses is not wrong, but it creates a more complex document and may imply reciprocal obligations that were not intended.

Protecting patent rights before you file

In UK and European patent law, novelty requires that the invention has not been made available to the public before the patent application priority date. An unprotected disclosure to a potential licensee — even a single meeting — can count as prior art that destroys the novelty of a future application.

An NDA signed before any disclosure keeps the information confidential and preserves novelty. This applies whether you have a pending application, an unregistered design, or a process you intend to protect through trade secrecy rather than patent registration.

The practical rule is simple: never disclose to a potential licensee without a signed NDA in place first.

Trade secrets and the Regulations

Licensing know-how — processes, formulations, algorithms, operational methods — may qualify for protection as trade secrets under the Trade Secrets (Enforcement, etc.) Regulations 2018, even where those methods are not patented.

Trade secret protection requires that the information has commercial value, is kept secret, and that the holder takes reasonable steps to maintain confidentiality. An NDA is one of those reasonable steps: it demonstrates that the other party received the information under a binding confidentiality obligation.

For trade secrets, indefinite or long-term confidentiality obligations in the NDA are appropriate — the value of a trade secret lasts as long as the information remains secret, and the Regulations provide indefinite statutory protection for qualifying secrets.

How long should a licensing NDA last?

Two to five years is the most common term for licensing NDAs covering commercial terms, pricing and business information. This reflects the typical licensing negotiation cycle and the time over which the disclosed information remains commercially sensitive.

For trade secrets — proprietary processes, software algorithms, formulations — longer terms or indefinite protection are appropriate. Include explicit post-termination obligations requiring return or destruction of disclosed materials, which remain enforceable after the NDA term expires.
