Trade Secrets: Identification, Protection &

Trade Secrets: The Most Undervalued Intangible Asset Category

Trade secrets are arguably the most pervasive and least understood category of intangible asset. Every business has them — confidential processes, customer insights, pricing strategies, supplier terms, technical specifications, and competitive intelligence that provide economic advantage precisely because they are not publicly known. Under IFRS 3, trade secrets are classified as technology-based intangible assets.

Unlike patents, which require public disclosure and have defined expiry dates, trade secrets derive their value from secrecy and can last indefinitely — provided the secrecy is maintained. This makes them simultaneously more durable than patents and more fragile: one careless disclosure can destroy the entire value.

What Qualifies as a Trade Secret

Under the EU Trade Secrets Directive (2016/943) and the UK's common law framework, a trade secret must satisfy three conditions:

It is secret — not generally known among or readily accessible to persons within the circles that normally deal with the kind of information in question
It has commercial value because it is secret — the secrecy itself provides economic advantage
Reasonable steps have been taken to keep it secret — the holder must actively protect the information

★ Key Takeaway

A trade secret is not just any confidential information. It must have commercial value that derives specifically from its secrecy, and the holder must demonstrate active protection measures. Information that is widely known, easily discoverable, or poorly protected does not qualify — and therefore has limited intangible asset value.

Identifying Trade Secrets in Due Diligence

Trade secret identification is often overlooked in M&A due diligence because, by definition, these assets are not publicly documented. A systematic identification exercise should examine:

Category	Examples	Where to Look
Technical processes	Manufacturing parameters, quality control procedures, formulations	Engineering documentation, SOPs, lab notebooks
Business information	Pricing models, cost structures, supplier terms, margin analysis	Finance systems, procurement records, pricing databases
Customer insights	Purchase patterns, propensity models, retention strategies	CRM systems, analytics platforms, marketing databases
Strategic plans	Product roadmaps, M&A targets, market entry plans	Board papers, strategy documents, executive communications
Competitive intelligence	Competitor analysis, market positioning, benchmarking	Strategy teams, sales intelligence, industry analysis

Protection Mechanisms

The value of a trade secret is directly proportional to the effectiveness of its protection. In a PPA, the valuer must assess both the quality of the secret and the quality of the protection:

Legal protections

Non-disclosure agreements with employees, contractors, and business partners. Employment contracts with confidentiality clauses. Trade secret policies documented and communicated to all staff.

Physical protections

Restricted access to facilities, locked document storage, visitor management. Manufacturing areas with limited access. Secure disposal of confidential waste.

Digital protections

Access controls on systems and databases. Encryption of sensitive data. Monitoring of data access and downloads. DLP (Data Loss Prevention) systems.

Organizational protections

Need-to-know access policies. Compartmentalisation so no single person has complete knowledge. Exit procedures including return of materials and exit interviews.

⚠ Warning

A trade secret that the company has failed to actively protect may lose its legal status and its intangible value simultaneously. In litigation, courts assess whether "reasonable steps" were taken to maintain secrecy. An unprotected secret is just information — and information available to all has no scarcity value.

Valuation Approaches

Cost Approach

The cost approach estimates the investment required to develop equivalent proprietary knowledge:

R&D expenditure — the historical or replacement cost of developing the technical knowledge
Data collection and analysis — the cost of compiling the competitive intelligence or customer insights
Trial and error — the investment in experimentation that yielded the successful formula, process, or approach

Income Approach

The income approach captures the economic advantage the trade secret provides:

Cost advantage — lower production costs due to proprietary processes or supplier terms
Revenue premium — higher prices due to unique product characteristics enabled by the secret
Time advantage — competitive lead time before rivals can develop equivalent knowledge

✔ Example

A speciality chemicals company is acquired with 45 proprietary formulations that are deliberately not patented (to avoid disclosure). The formulations enable 30% higher product performance than commercially available alternatives, supporting a 20% price premium on £25 million in annual revenue. Using the income approach — £5 million annual price premium, 8-year estimated useful life (the time for competitors to develop equivalent formulations through independent research), and 15% discount rate — the trade secret portfolio is valued at approximately £22.4 million.

Trade Secrets vs Other IP Categories

Trade Secret

No registration required
No disclosure obligation
No defined expiry
No protection against independent discovery
Lost permanently if disclosed

Patent

Formal registration required
Full disclosure mandatory
20-year defined term
Protection against all users (even independent developers)
Survives disclosure (it is the disclosure)

Useful Life

Trade secret useful lives are inherently uncertain. The secret persists as long as secrecy is maintained and the information remains commercially relevant. Practical useful life estimates consider:

Technology cycle — how quickly independent research could yield equivalent knowledge
Employee mobility — the risk of departing employees carrying knowledge to competitors
Reverse engineering risk — how easily the secret could be discovered through product analysis
Market relevance — how long the competitive advantage will remain commercially meaningful

Typical useful lives range from 3-15 years, though well-protected trade secrets in stable industries can endure for decades (Coca-Cola's formula, for example, has been a trade secret for over 130 years).

Building Trade Secret Value

For founders, the practical imperative is to systematically identify, document, and protect your trade secrets before a transaction. A trade secret audit — cataloguing what you know that competitors do not, and verifying that protection measures are in place — both strengthens the actual protection and creates the evidence base needed for intangible asset valuation in a future acquisition.

Trade secrets are one of ten technology-based intangible assets under IFRS 3. For the full taxonomy, see 35 types of intangible assets. For related content, read our guide to unpatented technology and know-how.
