Know-how and undisclosed business information, commonly referred to as trade secrets, are intangible assets of critical strategic importance for the growth, competitiveness, and innovative performance of European companies. Their value is particularly significant for innovations that do not meet patentability criteria or for entities that prioritize confidentiality over public disclosure, especially small and medium-sized enterprises (SMEs), which can thereby avoid the administrative and financial costs associated with obtaining patents.
Historically, the legal framework for protecting trade secrets varied significantly across the European Union, creating fragmentation that hindered cross-border collaboration and investment. To address this, Directive (EU) 2016/943 on the protection of trade secrets (“TSD”), adopted on June 8, 2016, aimed to harmonize national laws, establish a common definition of trade secrets, and provide effective civil remedies against their unlawful acquisition, use, and disclosure.
1. Understanding Trade Secrets: Definition and Key Criteria
The Trade Secrets Directive introduced a harmonized definition, incorporated in France under Article L.151-1 of the Commercial Code. For information to qualify as a trade secret, it must meet three cumulative criteria:
- Secrecy: The information must not be generally known or readily accessible, either in itself or in the precise configuration and assembly of its components, to persons familiar with this type of information due to their sector of activity. This may include know-how, R&D, customer and prospect files, supplier lists, contracts, accounting data, or new product launch plans. Assessing this criterion can be complex, particularly when the information is a compilation of elements, some of which are publicly accessible. Developments in big data and Internet of Things (IoT) applications require particular attention when interpreting the secrecy criterion, to clarify the role of trade secrets in the data economy.
- Commercial value: The information must have actual or potential commercial value because it is secret. A causal link must exist between the value of the information and its secrecy. This value may be assessed through the potential harm to the holder’s interests, such as competitive capability or strategic positioning. Courts, such as the Milan Tribunal, have recognized that commercial value may derive not from the information itself but from how it is processed through dynamic technologies, such as AI, and from the configuration of the dataset as a whole.
- Reasonable protection measures: The information must be subject to reasonable steps, under the circumstances, by its lawful holder to keep it secret. This criterion is frequently invoked as a defense in litigation and is often successful. It is understood as a principle of proportionality and flexibility, adapting to the value of the secret, the size of the company, and its sector. Proof of these measures must be objective rather than subjective.
2. The Importance of “Reasonable” Protection Measures
Legal protection of trade secrets is not automatic. It depends on the implementation and rigorous documentation of “reasonable protection measures.” This requires proactive diligence; failure to do so can seriously undermine legal remedies, even in cases of proven misappropriation. These measures must be multidimensional:
- Contractual measures: Non-disclosure agreements (NDAs) and confidentiality clauses in employment contracts are essential. Case law emphasizes the importance of clearly identifying the specific information subject to protection. Generic “confidential” labels are often insufficient.
- Technical measures: Companies must implement access control systems (logins, passwords), data encryption, alert and traceability systems for sensitive documents, and the use of virtual private networks (VPNs) for remote access. The integration of “decoys” (deliberately inserted errors) can facilitate proof of fraud.
- Organizational measures: Mapping and hierarchical classification of information (e.g., sensitivity levels C0, C1, C2, C3) help restrict access based on a “need-to-know” principle. Employee training and awareness regarding industrial espionage, cybercrime risks, and secure use of digital tools are critical. Appointing a dedicated trade secret manager ensures ongoing oversight.
3. Litigation Landscape and Enforcement Challenges
The EUIPO report of June 2023 indicates significant litigation activity within the EU, with 695 proceedings identified between 2017 and 2022. However, the success rate of infringement claims remains relatively low, around 27%, highlighting the practical challenges in proving trade secret misappropriation.
- Nature of disputed information: Litigation more frequently concerns commercial information (62%) than technical information (33%). The most common types involve downstream information (distribution methods, customer lists, marketing data) and financial information (pricing models, accounting data). The manufacturing sector is most often involved.
- Challenges and obstacles:
- Burden and difficulty of proof: Demonstrating the existence of a trade secret without disclosing it is a major challenge.
- Confidentiality during proceedings: Despite Article 9 of the Directive, preserving confidentiality during litigation remains a key concern. Measures such as “confidentiality clubs” (restricting access to a limited group such as lawyers and experts) and in-camera hearings are used to balance evidentiary rights and secrecy.
- Quantification of damages: Difficulties in assessing and proving damages, often intangible, can result in compensation perceived as insufficient by rights holders.
- Reluctance to litigate: Companies may prefer out-of-court settlements to avoid reputational risks linked to public disclosure of trade secret loss.
- Distinction between skills and secrets: Case law must continuously distinguish between trade secrets and employees’ experience and skills acquired in the normal course of employment, which are not protectable.
4. Financial Valuation and Strategic Implications
The financial valuation of trade secrets and know-how is directly influenced by the effectiveness of their protection and legal enforcement. An intangible asset, however innovative, cannot retain its value if it is vulnerable to misappropriation or difficult to enforce legally.
- Value preservation: Robust protection measures reduce the risk of unauthorized disclosure, allowing companies to maintain their competitive advantage and associated profits. The fact that a secret is “sufficiently recent to remain sensitive and strategic” is a key factor in its commercial value.
- Revenue potential: Well-protected trade secrets can generate revenue through licensing, partnerships, or co-development, as confidentiality assurance reassures potential partners. Valuation based on “reasonable royalties” is also a method used to calculate damages.
- Risk reduction: Proactive trade secret management reduces the risk of costly and complex litigation. In the event of a breach, strong documentation facilitates legal action and compensation, even if quantification remains difficult.
- New challenges in the data and AI economy: The emergence of the Data Act and the AI Act at the European level introduces data-sharing and transparency obligations, creating new tensions with trade secret protection, particularly for “data secrets” and AI algorithms. These regulations require companies to justify secrecy claims and prepare for controlled disclosures to regulators or users, which must be integrated into valuation strategies. Case law from the Court of Justice of the European Union indicates that trade secret protection cannot serve as a categorical ground for refusing disclosure. That disclosure must be balanced on a case-by-case basis.
Conclusion
Trade secrets and know-how are pillars of innovation and competitiveness. Their financial valuation is intrinsically linked to the robustness of the protection and enforcement measures in place. European and national legislation provide a framework, but the burden of proof and the complexity of litigation highlight the need for proactive and well-documented management of confidential information.
In a constantly evolving legal environment, with emerging regulations on data and AI, companies must adopt a holistic and integrated approach. This includes rigorous audits of intangible assets, the implementation of robust, well-documented contractual, technical, and organizational measures, and the continuous monitoring of legislative and case law developments.
The ability to effectively protect these intangible assets will determine not only the sustainability of competitive advantage but also their financial valuation. To navigate this complexity and maximize the value of trade secrets, expertise from specialized firms in financial valuation and intangible asset law is a decisive strategic asset.
