MEMORANDUM OPINION
GRADY, District Judge.Plaintiff has filed a motion seeking to have the court’s order of December 7, 1981, vacated.
FACTS
Plaintiff Soletanche and Rodio, Inc. (“plaintiff”), an American corporation, brought this suit against defendant for patent infringement. Plaintiff is the exclusive U.S. licensee of a French patent owned by Soletanche Societe Anonyme, a French corporation. This company, Soletanche Societe, S.A. (“Soletanche, S.A.”), owns 99.-8188 per cent of the stock of Soletanche Enterprise, S.A., another French corporation, which in turn owns 100 per cent of the stock of plaintiff. Both of these French corporations are involuntary plaintiffs in this action.
In preparing its defense to this action, defendant propounded several interrogatories regarding the validity of the patent. Plaintiff claims that it does not possess this information. According to plaintiff, only Soletanche Societe Anonyme or Soletanche Enterprise, S.A. possesses this information, and these companies are prohibited by French law from releasing it. See Law No. 80-538 of the French Republic, enacted July 17, 1980.1 This law forbids French citizens and corporations to communicate any information on economic, commercial, industrial, financial or technical matters to foreign public authorities. The penalty for violating this law is two to six months imprisonment and/or a fine of 10,000 to 120,000 French francs.
On September 23, 1981, we issued a minute order requiring plaintiff to respond to defendant’s interrogatories and to produce certain documents no later than November 30, 1981. On December 7, 1981, we issued the order which is the subject of this motion. In that order, we again ordered plaintiff to answer these interrogatories and indicated that we would dismiss the case if plaintiff failed to comply.
*271Plaintiff asserts that this order should be vacated because the court lacks the inherent power to dismiss this case for failure to comply with discovery requests and because French law does not preclude defendant from obtaining the information it seeks. DISCUSSION
Plaintiff is correct in arguing that the problem we are addressing must be dealt with in two stages. The first problem is whether we were correct in ordering plaintiff to answer defendant’s interrogatories, even though to do so would require the involuntary plaintiffs to violate French law. As the Seventh Circuit recently stated, “the fact that foreign law may subject a person to criminal sanctions in the foreign country if he produces certain information does not automatically bar a domestic court from compelling production.” USA v. Earl Tripplett, Revenue Officer, IRS v. The First National Bank of Chicago, 699 F.2d 341 at 345 (7th Cir.1983). In doing so, however, the court is required to engage in a sensitive balancing of the competing interests at stake in compelling such production. See id.
In United States v. Vetco, Inc., 691 F.2d 1281 (9th Cir.), cert. denied, 454 U.S. 1098, 102 S.Ct. 671, 70 L.Ed.2d 639 (1981), the court set forth the factors to consider in balancing competing interests. These factors are: vital national interests of each of the states; the extent and the nature of the hardship that inconsistent enforcement actions would impose upon the person; the extent to which the required conduct is to take place in the territory of the other state; the nationality of the person; and the extent to which enforcement by action of either state can reasonably be expected to achieve compliance with the rule prescribed by that state.
There is a strong American interest in not enforcing an invalid patent, for the effect would be to permit plaintiff to have an unwarranted, undeserved monopoly. We believe this concern outweighs the potential interest the French ■ might have in protecting industrial documents. This is especially so in this situation where plaintiff is seeking to invoke the protection of American laws without complying with the accompanying requirements of American law. See Trade Development Bank v. Continental Insurance Co., 469 F.2d 35 (2d Cir.1972) (holding that the court had the power to order a foreign domiciliary to obtain a waiver of foreign restrictions to producing evidence where the party was seeking to avail itself of the process of our courts). Without the answers to defendant’s interrogatories, we could not be assured that we would be enforcing a valid patent, nor would defendant be afforded a fair opportunity to defend itself against a claim of patent infringement.
With respect to the potential hardship our order would impose on plaintiff, we do not feel this outweighs the interests advanced by requiring plaintiff to provide the requested information. Violation of this French law could result in a short prison sentence and a fine (which would not exceed approximately $25,000.00), but we are not convinced that plaintiff would be penalized for complying with our order. As plaintiff admits in its memorandum submitted with this motion, the involuntary plaintiffs could request a waiver from the appropriate Minister, and if the waiver were granted, provide plaintiff with the necessary information without fear of punishment. In fact, the statute provides that persons affected by this law are supposed to inform the appropriate Minister, “without any delay,” whenever they are requested to supply information covered by this law. Therefore, compliance with our order would not impose too great a burden on plaintiff or the French Soletanches. We are simply requiring the French Soletanches to contact the appropriate Minister, as the law already requires them to do, and request a waiver so that they may comply with our order.
In the event that the French government denies the waiver request, we would still require plaintiff to supply the necessary information. As stated earlier, the interest of United States courts in not enforcing invalid patents outweighs the potential pen*272alties the French Soletanches might suffer in complying with our order.
Consideration of the other factors mentioned in United States v. Veteo, supra, would not alter our conclusion. Therefore, we deny plaintiff’s motion to vacate our order of December 7, 1981, and again hold that plaintiff must obtain the information necessary to answer defendant’s interrogatories adequately and fully.
The second stage of inquiry will arise if plaintiff fails to comply with our discovery order. While the question is not presented at this time, we believe that we should provide some guidance regarding the possible sanctions.
In Societe Internationale Pour Participations Industrielies Et Commerciales, S.A. v. Rogers, 357 U.S. 197, 78 S.Ct. 1087, 2 L.Ed.2d 1255 (1958), the Court held that the district court could not dismiss a plaintiff’s complaint for failure to comply with a discovery request where the plaintiff had made extensive good faith efforts to comply. The plaintiff in Societe, however, is distinguishable from the plaintiff here. In Societe, plaintiff made a good faith and diligent effort to comply with the discovery order and had tried to secure a waiver from the foreign government. Plaintiff in our case has merely requested its parent corporation to send the necessary information. Plaintiff has not demanded that the French Soletanches attempt to secure a waiver from the French government, nor has plaintiff independently sought such a waiver. The lack of such obvious efforts leads us to conclude that plaintiff has not used “extensive good faith efforts” to comply with our discovery order. Therefore, under the present circumstances, we would be inclined to dismiss plaintiff’s case without prejudice if it failed to produce the requested information. The Supreme Court’s holding in Societe would not be a bar to such a holding on these facts. The Court specifically stated that its ruling would not apply to every situation where a party is restrained by law from producing documents over which it is otherwise shown to have control. The Court held that the determination depends on the circumstances of a given case. See Societe, 357 U.S. at 205-206, 78 S.Ct. at 1092-1093. See also United States v. Vetco, Inc., supra, 691 F.2d at 1287 (holding that Societe left the district court wide discretion to use other means of obtaining compliance, to impose lesser sanctions against the plaintiff, and to draw inferences unfavorable to the plaintiff in the absence of complete disclosure).
With respect to plaintiff’s argument that we have not found it has control over the requested information, we disagree. In our order of December 7,1981, we held that this suit was really being brought for the benefit of Soletanche, S.A. and that plaintiff was merely an instrumentality by which Soletanche, S.A. exploits its patent in this country. Therefore, the actual plaintiff in this case is Soletanche, S.A. and this is the party which admittedly has control of the requested information. Given the identity of interests in this litigation, we feel that this satisfies any showing of control which might be necessary. Therefore, if plaintiff fails to comply with this discovery order, we will dismiss this case under Fed.R.Civ.P. 37(b)(2)(C), with leave to reinstate when the necessary information has been supplied.
CONCLUSION
Plaintiff’s motion to vacate our order of December 7, 1981, is denied. Plaintiff is hereby ordered to answer defendant’s interrogatories regarding the validity of its patent by May 23,1983. All other discovery is stayed pending plaintiff’s compliance with this order.
ORDER
In our opinion dated April 15, 1983, we ordered plaintiff to answer defendant’s interrogatories regarding the validity of its patent by May 23, 1983. Plaintiff was instructed that its failure to comply with our discovery order would result in dismissal of its case. On June 1, 1983, we heard arguments on defendant’s motion to dismiss this case under the terms of our April 15 opinion.
*273Plaintiff had not complied with our discovery order nor did plaintiff anticipate doing so in the near future. Therefore, we dismissed plaintiff’s case without prejudice with leave to reinstate at such time as the answers to the interrogatories are provided. As a further condition of reinstatement, plaintiff will be required to reimburse defendant for its reasonable attorney’s fees expended in connection with these discovery motions.
