Does the EU Data Act let data holders protect trade secrets during data access and sharing?
Yes. The Data Act says trade secrets must be preserved when product data or related-service data is disclosed to a user or to a third party chosen by the user. The data holder, or the trade-secret holder if different, should identify the protected data before disclosure, including in relevant metadata where needed.
That protection is not a general veto. The Commission FAQ explains that a data holder can decide which data it considers trade secrets, but that claim is not enough by itself to prevent Data Act access rights from being exercised.
- Identify the specific fields, records, metadata, or outputs that are claimed to contain trade secrets.
- Separate trade-secret material from data that can be shared without special confidentiality controls.
- Record whether the request is a user-access request under Article 4 or a third-party sharing request under Article 5, because the recipient obligations differ.
Article 4(6), Article 5(9), and Recital 31 support identifying trade secrets and preserving confidentiality before disclosure.
Question 23 explains that a trade-secret claim alone does not block the Data Act access right.
