What Qualifies as a Trade Secret? The 3-Part Test You Need to Know
Not everything is a trade secret. Here is the legal 3-part test, what qualifies and what doesn't, and the "reasonable steps" requirement that most businesses miss — which can destroy trade secret protection you thought you had.
Key Takeaway
Trade secret protection is powerful, but it can be lost. The most common reason companies lose trade secret protection is failing to document and demonstrate "reasonable steps" to maintain confidentiality. Blockchain timestamps are now part of best practice for demonstrating those steps — creating an immutable record that you identified specific information as confidential at a specific point in time.
1. The Legal Definition of a Trade Secret
Trade secret law exists in most major jurisdictions, each with specific definitions and requirements. The two most commercially relevant frameworks for UK and US businesses are:
UK: Trade Secrets (Enforcement, etc.) Regulations 2018
Implemented from the EU Trade Secrets Directive 2016/943, this defines a trade secret as information that:
- Is secret — not generally known among or readily accessible to persons in the circles that normally deal with the kind of information in question
- Has commercial value because it is secret
- Has been subject to reasonable steps under the circumstances to keep it secret
US: Defend Trade Secrets Act 2016 (DTSA)
Provides federal civil remedies for trade secret misappropriation. Defines a trade secret as information that:
- Is not generally known or reasonably ascertainable by proper means
- Derives independent economic value from not being generally known
- The owner has taken reasonable measures to keep secret
Covers formulas, patterns, compilations, programs, devices, methods, techniques, or processes.
2. The 3-Part Test in Plain English
Both UK and US law essentially apply the same three tests. All three must be met for trade secret protection to apply.
Not Publicly Known
The information must not be generally known in your industry or easily discoverable by those who work in it. This does not mean it must be completely secret from everyone — employees and partners may know it. It means it is not publicly available or obvious to those in the relevant field.
Qualifies
- A proprietary manufacturing process used internally but not documented in public filings
- A customer database that you have built over years
- A blended formula or algorithm not derivable from the product itself
Does not qualify
- Information published in your marketing materials
- A process that is standard industry practice
- Information that could be reverse-engineered easily from your product
Economic Value from Secrecy
The secrecy itself must be the source of the commercial value. If a competitor knew your trade secret, it would give them an unfair advantage. If the information would have no commercial impact if disclosed, it likely does not qualify.
Strong value from secrecy
- A pricing algorithm that lets you consistently undercut competitors while maintaining margin
- A customer segmentation model that drives above-average conversion rates
- A proprietary synthesis process that is cheaper than industry standard
Weak or no value from secrecy
- General business processes that any competent company uses
- Financial records (protected differently, under data protection law)
- Information about which software tools your team uses
Reasonable Steps to Protect
This is where most businesses fail. You must be able to demonstrate that you actively took steps to keep the information confidential. Courts look at what was reasonable given the size and sophistication of your business.
Demonstrates reasonable steps
- NDAs signed by all who access the information
- Access controls limiting who can view the documentation
- Documented classification of information as confidential
- Blockchain timestamps proving when you identified information as confidential
Insufficient
- Informal, undocumented understanding that something is secret
- NDAs signed after the information was already shared
- No access restrictions or logging
- Treating the information as confidential only after a dispute arises
3. What Qualifies as a Trade Secret — Real Examples
The most famous trade secret in history is the Coca-Cola formula — protected for over 130 years. A patent would have expired after 20. The formula's value comes precisely from it remaining secret.
4. The "Reasonable Steps" Requirement and Why It Matters
Of the three requirements, "reasonable steps" is the one most businesses underestimate — and the one most often cited when trade secret claims fail in court.
Courts assess "reasonable steps" based on what was practical given the nature and size of the business. A startup is not expected to have the same security infrastructure as a multinational. But a startup is expected to have some procedures in place.

5. How Blockchain Timestamps Strengthen Your Trade Secret Claim
When a trade secret dispute reaches litigation, the two questions at issue are: (1) was this information actually confidential? and (2) did the defendant know it was confidential when they accessed or used it?
Blockchain timestamps address both questions. By timestamping your confidential documentation, you create a cryptographically verifiable record proving that:
- Specific information existed and was documented at a specific date and time
- You took an active step to protect and record that information on that date
- The information predates the alleged misappropriation
How immut Works for Trade Secrets
- Document your trade secret — what it is, why it has commercial value, and your confidentiality procedures
- Upload to immut — we create a cryptographic hash and record it on the XRPL blockchain
- Receive your timestamp certificate — an immutable record with an exact date and cryptographic proof
- Store the certificate with your IP documentation — available as evidence if needed
Compare this to the alternative: attempting to prove in court, years later, that information was confidential based on informal practices and undocumented understandings. The blockchain approach creates a clear, objective record.

6. Common Mistakes That Destroy Trade Secret Protection
Disclosing publicly before protecting
Once information is in the public domain — published, presented at a conference, included in marketing — it can no longer qualify as a trade secret. There is no reverting this.
Sharing without NDAs
If you share trade secret information without a confidentiality agreement, courts may find that you did not take reasonable steps to protect it. The absence of an NDA in a disclosure can destroy a trade secret claim.
Inconsistent classification
If you treat some information as confidential but not others without a clear system, courts may question whether you actually maintained a confidentiality regime at all.
No documentation of what is confidential
If you cannot point to specific documentation identifying specific information as confidential at a specific point in time, your claim is weaker. This is where timestamps become particularly valuable.
Failing to update procedures as the business grows
Protection that was sufficient for a 3-person startup may not be considered reasonable steps for a 50-person company. Review and update your trade secret procedures regularly.
Frequently Asked Questions
What is a trade secret?
A trade secret is commercially valuable information that is kept confidential and gives a business a competitive advantage. Under UK law (Trade Secrets Regulations 2018), trade secrets must meet three criteria: not generally known, commercial value from secrecy, and the holder must have taken reasonable steps to keep them secret.
Does a trade secret need to be registered?
No. Trade secrets do not need to be registered with any government body. Protection arises automatically when you meet the three-part test and actively maintain secrecy. However, you must be able to prove that you took reasonable steps to protect the secret.
What counts as reasonable steps to protect a trade secret?
Reasonable steps typically include: NDAs with all who access the information, access controls, documented classification of information as confidential, blockchain timestamps proving when you identified information as confidential, and employee awareness procedures.
Can a business idea be a trade secret?
A business idea can qualify as a trade secret if it meets the three-part test: not generally known, commercial value from secrecy, and you have taken reasonable steps to protect it. Vague ideas are harder to protect. Documented, developed business concepts with clear commercial value have stronger trade secret protection.
