Infringement may be proved by any means.
To this end, any person having standing under this title shall be entitled to have carried out at any place and by any bailiffs, where appropriate assisted by experts appointed by the plaintiff, by virtue of an order made on request by the competent civil court, either the detailed description, with or without taking samples, or the actual seizure of the allegedly infringing objects as well as any document relating thereto. The order may authorise the actual seizure of any document relating to the allegedly infringing objects in the absence of the latter.
The court may order, for the same evidentiary purposes, the detailed description or actual seizure of the materials and instruments used to produce or distribute the allegedly infringing objects.
It may make the execution of the measures it orders subject to the provision by the plaintiff of guarantees intended to ensure the possible indemnification of the defendant if the action brought under this title is subsequently found to be unfounded or the seizure annulled.
If the plaintiff fails to take civil or criminal action on the merits of the case within a period set by regulation, the entire seizure, including the description, shall be annulled at the request of the distrainee, without the latter having to give reasons for his request and without prejudice to any damages that may be claimed.
