Definition: a trade secret is information which meets all of the following requirements: (1) it 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; (2) it has commercial value because it is secret; (3) it has been subject to reasonable steps under the circumstances, by the person lawfully in control of the information, to keep it secret.

Criteria for enforcement: in order to be protected, trade secrets must have been obtained by any of the following means: (1) independent discovery or creation; (2) observation, study, disassembly or testing of a product or object that has been made available to the public or that is lawfully in the possession of the acquirer of the information who is free from any legally valid duty to limit the acquisition of the trade secret; (3) exercise of the right of workers or workers' representatives to information and consultation in accordance with Union law and national laws and practices; (4) any other practice which, under the circumstances, is in conformity with honest commercial practices.

Assignment - licensing: there are no formal requirements for the assignment of trade secrets. According to the leading opinion, company and trade names can only be assigned with the transfer of the business. Trade secrets, like all intellectual property rights, can be freely licensed, exclusively or non-exclusively, in the form of a written agreement.

Remedies for misappropriation: provisional and precautionary measures are available against the alleged infringer, such as the cessation and the prohibition of the infringement in the future, the prohibition of any action involving infringing goods and the seizure or delivery of the suspected infringing goods. Alternatively, the competent authorities may relate the continuation of the infringement to the lodging of guarantees so as the trade secret holder can be compensated. In any case, the disclosure of a trade secret in return for the lodging of guarantees is not allowed. The interested party asking for provisional and precautionary measures is obliged to file a lawsuit within twenty working days or thirty-one calendar days starting from the day of issue of the decision on the provisional and precautionary measures application, otherwise this decision's results are automatically annulled.
