The plaintiffs have moved that the bill of complaint, filed by them against the. Shevlin-Hixon Company to enjoin the alleged infringement by that company of letters patent No. 1,123,155, owned by the, plaintiffs, be dismissed without prejudice and with costs against the plaintiffs. An answer has been filed. No counterclaim is therein made. No testimony has been taken by either party. After the motion was set down for hearing, H. J. Burns asked to be made a party defendant. In his petition of intervention he alleges that he is the manufacturer of the apparatus claimed to infringe; that the apparatus in the plant of the Shevlin-Hixon Company, here, complained of, was installed by hint; that he assumed the defense of this suit, and has paid the expenses thereof with the knowledge of the plaintiffs; that he is informed and believes that prospective customers of defendant’s apparatus have been threatened by the plaintiffs with infringement suits; that his business has been thus interfered with to his damage; and that he desires to ayoid a multiplicity of suits and further damage to himself by having the question of whether or not the apparatus manufactured by him is an infringing one finally and promptly settled in and by this suit. In his proposed answer, which was submitted with the petition to intervene, Burns makes the allegations usual in an answer filed in an infringement suit. He also repeats therein the statements made, as above narrated, in his petition of intervention. He prays in his answer, not only that the bill of complaint be dismissed, but also, in reliance upon Kessler v. Eldred,
There is no local rule touching the voluntary dismissal of bills in equity. In the absence of such a rule the general principles of law pertaining thereto must govern. These principles have been recently summarized by Mr. Chief Justice Taft in Ex parte Skinner & Eddy Corp.,
In the Skinner & Eddy Case it was further said: “The usual ground for denying a complainant in equity the right to dismiss his bill without prejudice at his own costs is that the cause has proceeded so far that the defendant is in a position to demand on the pleadings an opportunity to seek affirmative relief and he would be prejudiced by being remitted to a separate action. Having been put.to the trouble of getting his counter case properly pleaded and ready, he may insist that the cause proceed to a decree.”
In Kessler v. Eldred,
Before taking up the questions of Bums’ right to intervene, the right of an intervener to obtain affirmative relief not obtainable by the original defendant, the right of an intervener to oppose a motion of a plaintiff to dismiss its own bill, and, if an intervener has such right, whether a person who delays making an application to intervene and to obtain affirmative relief until after plaintiffs move to dismiss their bill does not come too late successfully to oppose the motion to dismiss, let Bums’ right to prevail in his opposition to plaintiffs’ motion be first tested as if he were the original and sole defendant, and that, as such
*749
defendant, he had filed the answer he now offers to file. As the general rules touching the right of a plaintiff to dismiss his own bill apply with like force to an infringement suit in equity against the manufacturer of the alleged infringing device, Burns could not, even if he were an original and sole defendant, prevent the dismissal sought by the plaintiffs, unless he could show prejudice otherwise “than by tho mere prospect of being harassed and vexed by future litigation of tho same kind.” If Burns has here shown that he would be otherwise prejudiced, it is because, and only because, he has shown by his allegations, affidavits, and prayer for affirmative relief that he is here in a position to obtain the affirmative relief he desires, and that he would he prejudiced by being remitted to a new action. Yet, even if it be assumed that a manufacturer of an apparatus who is a successful party defendant in an infringement suit may in that suit obtain by way of affirmative relief an injunction of like tenor as that which may he awarded to him in an independent suit (Kessler v. Eldred,
Turning from questions of law to the facts set up by the affidavits and alleged in the proffered answer, it is not there established, or even shown probable that, should the question of whether or not Burns’ apparatus does infringe plaintiffs’ patent be settled in favor of Burns in a suit between tho plaintiffs and Burns, the plaintiffs would thereafter institute or threaten to institute suits against Burns’ customers, actual or prospective, or otherwise interforo with his business.
But Burns is not a party defendant. Is he a person who is entitled under equity rule 37 to intervene? Tho maker of an alleged infringing article has in many eases been permitted to intervene in a suit instituted against one who has sold or used the article. Wenborne-Karpen Dryer Co. v. Dort Motor Car Co. (D. C.)
But, were he not too late, is it clear that an intervening party defendant may set up in his answer every counterclaim of an equitable character that ho may have against the plaintiff? Under equity rule 30 the right of an original party defendant to set up in his answer his counterclaims against the plaintiff is very broad. American Mills Co. v. American Surety Co.,
Por the reasons stated, I am of the opin *750 ion that the application of Burns to intervene as a party defendant should be denied, and the motion of plaintiffs to dismiss their bill of complaint without prejudice upon payment of the costs should be granted.
