The creator of a protected layout-design of integrated circuits or his beneficiaries may, if he has serious reasons to suspect an operation involving the import of goods comprising copied layout-designs of integrated circuits, submit to the customs authorities a written request, demanding the suspension of customs clearance for the import of the goods. The requestor shall be obliged to inform the customs authorities in the case where his right no longer appears to have valid registration or appears to have expired. 40. The application provided for in Article 39 of this Law shall contain: — the first name and surname or business name of the requestor, his domicile or registered office; — proof establishing that the requestor is the owner of a right in the goods which are the subject of the dispute; — a description of the goods sufficiently accurate as to allow the customs authorities to recognize them. In addition, the requestor shall supply all the other useful information available to him to allow the customs authorities to take a fully informed decision, without, however, the submission of this information constituting a requirement for the admissibility of the request. This information shall relate, inter alia, to the: — place where the goods are located or the planned destination, — identification of the parcel or of the packages, — date of arrival or planned deposit of the goods, — means of transport used, — identification of the importer, exporter or holder of the goods. The request shall also contain the undertaking of the requestor to assume responsibility in relation to the importer, if it is formally proven that the goods withheld by the customs authorities do not constitute an infringement of the protected layout-design of integrated circuits. 41. The customs authorities, to which a request drawn up in accordance with Article 39 of this Law is submitted, shall examine the request and immediately inform the requestor in writing of the decision taken.
