This is a suit under the patent laws and was instituted pursuant to and in accordance with the provisions of the Declara
The defendant moves to dismiss this suit, and, in the alternative, to stay the prosecution thereof until the suit pending in the United States District Court, District of Massachusetts, is adjudicated. The plaintiff and the intervenor move to enjoin further proceedings in the latter suit until this suit has been adjudicated.
The question presented by these motions has been decided by the Circuit Court of Appeals for the Third Circuit. It is well established that in all cases of concurrent jurisdiction the court first acquiring that jurisdiction should retain it until there is a final adjudication, and, in order to prevent vexatious litigation and a multiplicity of suits, should enjoin the parties from further proceedings in another forum. Triangle Conduit & Cable Co., Inc., v. National Electric Products Corp., 3 Cir.,
The defendant, recognizing the applicability of the rule, contends that its application in the instant case requires that the proceedings instituted by the intervenor in this court be stayed until there has been a final adjudication in the suit pending in the United States District Court, District of Massachusetts. It seems obvious that this contention, if adopted, would nullify the rule and defeat its very purpose; two suits in which there are identity of issues and parties would be prosecuted to conclusion unnecessarily.
The defendant, in support of its contention, argues that the suit of the intervenor must be regarded as having been commenced on April 20, 1942, the date of the intervention. The argument is, in the opinion of this Court, without merit. Intervention presupposes the pendency of a suit in a court of competent jurisdiction, and one who voluntarily becomes a party thereto, impliedly, if not expressly, accepts the proceedings as he finds them át the time of the intervention; the intervenor is, for all intents and purposes, an original party. Marsh v. United States, 4 Cir.,
The motion of the defendant is, for the reasons hereinabove stated, denied. The motion of the plaintiff and intervenor is, likewise for the reasons hereinabove stated, granted.
