Member States shall also ensure that the competent judicial authorities may, on a duly reasoned application by a party, take specific measures necessary to preserve the confidentiality of any trade secret or alleged trade secret used or referred to in the course of legal proceedings relating to the unlawful acquisition, use or disclosure of a trade secret. Member States may also allow competent judicial authorities to take such measures on their own initiative.

(b) of restricting access to hearings, when trade secrets or alleged trade secrets may be disclosed, and the corresponding record or transcript of those hearings to a limited number of persons;
(c) of making available to any person other than those comprised in the limited number of persons referred to in points (a) and (b) a non-confidential version of any judicial decision, in which the passages containing trade secrets have been removed or redacted.
The number of persons referred to in points (a) and (b) of the second subparagraph shall be no greater than necessary in order to ensure compliance with the right of the parties to the legal proceedings to an effective remedy and to a fair trial, and shall include, at least, one natural person from each party and the respective lawyers or other representatives of those parties to the legal proceedings.

3. When deciding on the measures referred to in paragraph 2 and assessing their proportionality, the competent judicial authorities shall take into account the need to ensure the right to an effective remedy and to a fair trial, the legitimate interests of the parties and, where appropriate, of third parties, and any potential harm for either of the parties, and, where appropriate, for third parties, resulting from the granting or rejection of such measures.

4. Any processing of personal data pursuant to paragraphs 1, 2 or 3 shall be carried out in accordance with Directive 95/46/EC.

Protected confidential information – trade secrets (Article 9 Trade secret directive, Article 58 UPCA, Rule 262A RoP). Information on profit margin can be classified as confidential if it is not available from publicly accessible sources.Information about the few employees having access to this financial information appears to be valuable and confidential in itself. Information that certain products do not support certain functionalities may also be confidential. The existence of a negative fact therefore does not per se exclude the need for secrecy.

IPPT20240809, UPC CFI, LD Hamburg, AGFA v Gucci
Confidentiality club protection for trade secrets and confidential information, restricting use or disclosure outside of the present court proceedings.  (Rule 262A RoP, Article 9 Trade Secrets Directive). The existence of a trade secret does not have to be established to the court's satisfaction, but it is sufficient if this is predominantly probable. The following information relating to the internal organization, the supply chain and sales data of the Gucci group are classified as confidential pursuant to R. 262A RoP. Restricting the use of confidential instead of limiting access thereto, does not endanger the right of the other party right to be heard and the right to argue its case successfully and does not does not require the same strict balancing of interest as a limitation of access within the proceedings.
