The French patent litigator can play an important role in a saisie-contrefaçon by representing the plaintiff (especially patent owners) before the competent courts. He can assist the plaintiff in establishing the facts and evidence necessary to support his “saisie” request. He will then file his motion ex parte (in the absence of the opposing party) in order to obtain an authorization for seizure operations at the infringer’s premises to recover evidence of the materiality and extent of the infringement (technical and accounting documents).
