As reported here, the Ist Senate of the BGH (responsible for trademark matters) has referred an interesting question to the ECJ:
Is Art. 8 par. 3 Lit. e of the directive 2004/48/EG to be interpreted such that this provision is in conflict with a national regulation enabling a banking institute in a case as the one as issue to deny access information on the name and address of the owner of an account according Art. 8 par. 1 lit. c of this directive with reference to the banking secrecy?(referring decision: "Davidoff Hot Water" (I ZR 51/12),
In the case at issue, counterfeit products were sold via e-bay and the payments were received on an account kept by a bank which was sued by the trademark owner to provide information on the account holder, which the bank refused.
The ECJ asserts that (par. 33, emphasis added):
The present request for a preliminary ruling thus raises the question of the need to reconcile the requirements of the protection of different fundamental rights, namely the right to an effective remedy and the right to intellectual property, on the one hand, and the right to protection of personal data, on the other (see, to that effect, judgment in Promusicae, C‑275/06, EU:C:2008:54, paragraph 65).And finds that (par. 39 and 40)
... unlimited and unconditional authorisation to invoke banking secrecy is such as to prevent the procedures laid down by Directive 2004/48 and the measures taken by the competent national authorities, in particular when they seek to order the disclosure of necessary information under Article 8(1) of that directive, from taking due account of the specific characteristics of each intellectual property right and, where appropriate, the intentional or unintentional character of the infringement.
It follows that an authorisation of that kind is capable of seriously impairing, in the context of Article 8 of Directive 2004/48, the effective exercise of the fundamental right to intellectual property — to the benefit of the right of persons covered by Article 8(1) of Directive 2004/48 to the protection of personal data concerning them — as a result of the obligation, for a banking institution, to respect banking secrecy.
The task to find "any other means or remedies" (par. 42) or to establish criteria are to be applied for striking the right balance between the right to intellectual property, on the one hand, and the right to protection of personal data is left to the referring court. The repeated reference to recital 17 of the Directive 2004/48 implies that the intentional or unintentional character of the infringement should play a role.
