Trade secret
What is a trade secret?
A trade secret is confidential business information that has economic value because it is not generally known or readily accessible to people who normally deal with that type of information. In practice, a trade secret may cover technical know-how, manufacturing methods, formulas, source code, customer lists, pricing models, business strategies, product roadmaps, internal procedures, or other commercially sensitive information.
Under Article 2(1) of Directive (EU) 2016/943, a trade secret means information which: “is secret in the sense that it is not, as a body or in the precise configuration and assembly of its components, generally known among or readily accessible to persons within the circles that normally deal with the kind of information in question”, “has commercial value because it is secret”, and “has been subject to reasonable steps under the circumstances, by the person lawfully in control of the information, to keep it secret”. These three elements are usually treated as cumulative. If one of them is missing, legal protection may be limited or unavailable.
The concept is important in commercial practice because not every valuable business asset can or should be protected through registration rights such as patents, trademarks, or designs. Some information is better protected through confidentiality. A trade secret can therefore function as a practical legal tool for preserving competitive advantage, especially where disclosure would weaken a company’s market position or reveal how it operates.
What does trade secret protection cover?
Trade secret protection may apply to many areas of business activity. In technology-focused businesses, it often concerns algorithms, software architecture, technical documentation, prototypes, test results, and security solutions. In manufacturing, it may involve recipes, specifications, tolerances, assembly methods, supplier arrangements, and production processes. In service-based businesses, it often includes client data, pricing policies, contract terms, sales methods, market analysis, and internal operating models.
Protection does not arise automatically from the fact that information is important or confidential in a general sense. A business must usually show that it took reasonable steps to preserve secrecy. Depending on the circumstances, this may include non-disclosure agreements, access controls, internal classification rules, confidentiality clauses in employment and B2B contracts, IT security measures, document marking, staff training, and procedures for onboarding and offboarding employees or contractors.
It is also important to distinguish lawful use of knowledge and experience from unlawful acquisition, use, or disclosure of a trade secret. Not every transfer of know-how between workplaces is prohibited. Disputes often concern the boundary between an employee’s general professional skills and specific confidential information belonging to the employer. The assessment depends on the facts, the type of information, the way it was stored and shared, and the safeguards actually used by the business.
When is legal assistance regarding a trade secret useful?
Legal support may be needed both preventively and after a conflict has already arisen. For businesses, advice is often useful when identifying which information should be treated as a trade secret, designing confidentiality procedures, drafting contracts, preparing internal policies, or assessing the risk of disclosure during cooperation with employees, subcontractors, investors, distributors, or business partners.
Assistance is also important in contentious situations. This may include suspected misuse of confidential information by a former employee, unauthorised transfer of files, disclosure during negotiations, use of protected know-how by a competitor, leakage of customer databases, or disputes connected with corporate transactions, outsourcing, or joint development projects. In these cases, a lawyer may help assess whether the information meets the legal criteria of a trade secret, what evidence should be secured, and what claims or remedies may be available.
Individuals may also need advice when changing jobs, starting a competing business, signing confidentiality clauses, or responding to accusations that they used confidential information unlawfully. Early legal analysis can reduce the risk of breaching contractual obligations, infringing trade secret rules, or becoming involved in avoidable litigation.
A prompt consultation may help prevent errors that lead to loss of confidentiality, evidentiary problems, contractual disputes, civil liability, or financial loss. It may also support a more effective response where sensitive information has already been disclosed or misused.
Law firm support in matters involving trade secrets may include in particular:
- assessment of whether specific information qualifies as a trade secret,
