The EU Trade Secrets Directive 2016/943 contains a variety of confidentiality protections expressly protecting the publicity of the proceedings because “[t]he prospect of losing the confidentiality of a trade secret in the course of legal proceedings often deters legitimate trade secret holders from instituting legal proceedings to defend their trade secrets, thus jeopardising the effectiveness of the measures, procedures and remedies provided for. For this reason, it is necessary to establish, subject to appropriate safeguards ensuring the right to an effective remedy and to a fair trial, specific requirements aimed at protecting the confidentiality of the litigated trade secret in the course of legal proceedings instituted for its defence.” Article 9 of the Directive specifically required EU member states to implement rules creating such protections, such as by restricting access to hearings and creating so-called “confidentiality rings” or “confidentiality clubs” limiting the dissemination of confidential information and documents to designated persons.
The United Kingdom’s implementing law, the Trade Secrets (Enforcement, etc.) Regulations 2018, requires that the court have the power to restrict access to documents containing alleged trade secrets and to hearings. s. 10(5). There is already significant maturity in the kinds of confidentiality protections available in English litigation so this is unlikely to lead to significant change. Although the principle of open justice is a fundamental feature of the legal system and departures are permitted only if necessary in the interests of justice, exceptions and restrictions to openness and respect for confidentiality are actually already well-established in the United Kingdom.
