Protecting Trade Secrets: Current Law and Practical Insights

In today’s knowledge-driven economy, information can be a company’s most valuable asset. Whether it’s a manufacturing formula, a client database, or a new algorithm, protecting trade secrets is vital to maintaining a competitive edge. The United Kingdom provides a well-developed legal framework for that protection through both common law and statute. Together, they form a flexible yet powerful system for companies seeking to preserve confidentiality and deter misuse.

Dual Protection: Common Law and Statute

Trade secrets in the UK are protected through two main channels: the common law of confidence and the Trade Secrets (Enforcement, etc.) Regulations 2018. The two systems coexist, offering overlapping remedies and definitions.

Under common law, breach of confidence claims rely on the classic Coco v A.N. Clark (Engineers) Ltd test. To succeed, a claimant must prove that:

1. The information had the necessary quality of confidence;
2. It was disclosed in circumstances implying an obligation of confidence; and
3. It was misused without permission.

This framework has long been the cornerstone of UK confidentiality law. However, it was supplemented in 2018 when the UK implemented the EU Trade Secrets Directive through domestic regulations.

The 2018 Regulations define a “trade secret” as information that:

• Is not generally known or readily accessible;
• Has commercial value because it is secret; and
• Has been subject to reasonable steps to keep it secret.

This statutory definition mirrors international standards and gives clearer structure to the concept of a trade secret. Importantly, businesses can pursue claims under both the common law and the Regulations, depending on the facts of the case.

What Qualifies as a Trade Secret?

Trade secrets can include a wide range of information – manufacturing processes, technical know-how, customer data, pricing models, or strategic plans. What matters is secrecy, value, and protection.

The UK courts emphasise that the information must not be public or easily discoverable. Even if components of the knowledge are known, the specific combination or arrangement may qualify as secret. For instance, a database of client preferences, compiled through years of commercial experience, can be protected even though customer names themselves are not confidential.

The “commercial value” requirement does not demand a precise monetary figure. It simply means that the information confers a competitive or economic advantage. Courts typically evaluate value by asking whether losing the secret would harm the business.

Finally, the claimant must show reasonable steps were taken to preserve confidentiality. This may include contractual restrictions, password protection, physical security, restricted access, or labelling documents “confidential.” Courts assess reasonableness in light of the nature of the information and industry standards.

The Impact of the National Security Act 2023

Beyond civil remedies, the UK has introduced criminal sanctions for certain types of trade secret misuse. Under Part 4 of the National Security Act 2023, it is an offence to obtain, copy, retain, disclose, or provide access to a trade secret on behalf of a foreign power without authorisation. The maximum penalty is 14 years’ imprisonment and an unlimited fine.

This development reflects growing government concern about industrial espionage and the security implications of technology transfer. Companies working in sensitive sectors—such as defence, energy, and advanced technology—should be particularly vigilant about safeguarding their confidential data.

Remedies for Misuse

If a trade secret is misused, the UK courts can grant a range of remedies:

• Injunctions to stop further use or disclosure of the information;
• Delivery up or destruction of infringing materials;
• Damages or an account of profits for economic loss; and
• Springboard injunctions, which prevent a competitor from gaining a head start from the misuse.

Springboard injunctions are unique to trade secret cases. They are designed not to punish the wrongdoer but to neutralise any unfair advantage obtained through misuse, typically lasting until the information becomes public or obsolete.

Practical Protection Strategies

To maximise legal protection, businesses must combine legal tools with operational discipline. Recommended best practices include:

1. Identify what needs protecting – conduct an audit of valuable information and categorise it by sensitivity.
2. Restrict access – share trade secrets only with employees or partners who truly need to know them.
3. Use contractual safeguards – incorporate confidentiality clauses and non-disclosure agreements in employment and supplier contracts.
4. Label and monitor – clearly mark documents as confidential and use access logs for digital files.
5. Educate employees – train staff on information security policies and the risks of casual disclosure.
6. Plan for departures – ensure departing employees return all confidential materials and understand ongoing obligations.
7. Respond quickly to breaches – investigate suspected leaks promptly, secure evidence, and seek urgent injunctions if necessary.

Taking such measures is vital not only to prevent disclosure but also to prove compliance with the “reasonable steps” requirement if a dispute arises.

Key Takeaways

The UK’s system for trade secret protection is both comprehensive and adaptable. Common law provides flexibility and a broad range of equitable remedies, while the 2018 Regulations offer clarity and consistency aligned with international standards. The new criminal provisions under the National Security Act demonstrate the state’s willingness to treat trade secret theft as a matter of national importance.

For businesses, the message is clear: the law can protect confidential information—but only if the business treats it as such. Identifying trade secrets, securing them effectively, and maintaining clear documentation of protective steps are essential foundations for enforcement.

As competition intensifies and the digital economy expands, trade secret management has become a critical component of corporate governance. Investing in strong confidentiality practices today will pay dividends in safeguarding innovation and preserving commercial advantage tomorrow.
