The Spanish State enacted Law 1/2019 to transpose EU Directive 2016/943, establishing a comprehensive legal framework for the protection of trade secrets against unlawful acquisition, use, and disclosure. The legislation defines trade secrets based on secrecy, commercial value, and reasonable protection measures, while explicitly safeguarding fundamental rights such as freedom of expression and worker mobility. It introduces robust civil and procedural remedies, including precautionary measures and specific rules for confidential proceedings, to ensure effective judicial protection within the internal market.
