(1) In the event of a legal infringement being committed on a commercial scale in the cases referred to in section 139 (2), the aggrieved party may also require the infringer to produce bank, financial or commercial documents or to provide appropriate access to the relevant documents of which the infringer has disposal and are necessary for enforcing the claim for compensation if there is doubt as to whether the claim for compensation will be satisfied in the absence of such production. Where the infringer asserts that the information is confidential, the court takes the measures necessary to ensure the specific protection required in an individual case.
(2) The claim under subsection (1) is ruled out if its assertion is disproportionate in an individual case.
(3) The obligation to produce the documents referred to in subsection (1) may be imposed by means of an injunction in accordance with sections 935 to 945 of the Code of Civil Procedure in cases where there evidently is a claim to compensation. The court takes the measures necessary to ensure the protection of confidential information. This in particular applies to those cases where the injunction is issued without giving a prior hearing to the opposing party.
(4) Section 811 of the Civil Code and section 140b (8) of this Act apply accordingly.
