(after stating the facts as above). A demurrer was interposed to the bill. The decision of Judge Seaman (164 Fed. 84) overruling the demurrer has settled the law of this case, following Farquhar v. National Harrow Company, 102 Fed. 714, 42 C. C. A. 600, 49 L. R. A. 765, Adriance Platt & Co. v. National Harrow Co., 121 Fed. 827, 58 C. C. A. 163, and Emack v. Kane (C. C.) 34 Fed. 46, distinguishing the case of Francis v. Flinn, 118 U. S. 385, 6 Sup. Ct. 1148, 30 L. Ed. 165. Therefore it only remains to determine whether the proofs sustain the substantial averments of the bill.
At the outset we are met by this strange situation: Although both parties claim to have been manufacturing under letters patent, and the fact that complainant’s supposed infringement has been well known to defendant for more than five years before this suit was brought, no effort has been made by it to establish its monopoly or to check the alleged infringement in the usual, orderly way. No suit has been brought against Dittgen, or against any user of his product. This circumstance goes- far to impeach the good faith of representations made by defendant to the trade that complainant during all these years has been encroaching upon the claims of its patents.
The proofs now before the court render this conclusion of bad faith irresistible. Defendant is brought before a court of equity to answer for alleged false and malicious representations to complainant’s customers as to its monopoly, and to answer complainant’s contention that he has been operating lawfully under his own patent, and that he *88has not infringed any 'claim of defendant’s patents. Under these circumstances .the defendant omits to offer in evidence either its own letters patent or that of complainant. It surrenders the basic contention. Furthermore, it is admitted by Parmenter, the general manager of defendant, that he frequently discussed with the .trade the effect of a certain interference in the Patent Office; but no proof is offered to show that any such interference was ever declared, or ever decided, much less what patents or points were involved therein. In this 'state of the record we are forced to the conclusion that whatever claims of monopoly were made ■ by defendant, and all charges of infringement against complainant, were falsely and maliciously made.
Another significant circumstance in the same line is that under date of April S3, 1902, complainant wrote defendant complaining of its methods and of the false representations it was making to the trade. He inclosed a sample of the pouch that he was manufacturing, for its inspection, and requested defendant, if it still thought that there was an infringement, to bring suit, and he would accept service .in any court having jurisdiction. He also denounced them as “bluffers” if they dared not accede to his proposition. This letter elicited no response, except that Mr. Parmenter was away from home. Therefore defendant has practically left itself in this attitude on the record: That it was seeking to secure a practical monopoly by a system of commercial compulsion; that the process of the court was unnecessary if by its own processes it could stampede the customers of its sole competitor and secure the business for itself. The only resource left for defendant seems to have been a general denial, and we have only to settle the question of fact.
Parmenter, business manager of defendant, takes the stand and practically denies everything, except that he discussed with the trade the matter of an interference in the Patent Office. He denies that he employed threats of litigation. He is confronted by a multitude of witnesses, who appear to be disinterested, who assert the truth of the statements made in a large number of letters produced in evidence, which were written in the ordinary course of business, relating conversations with Mr. Parmenter and other of defendant’s salesmen', wherein they threatened suits against any users of complainant’s pouches. Not only this, but he is virtually contradicted by his own letters, written to the complainant, wherein are clearly displayed the weapons and methodq to be employed in the crusade against complainant. His letters, written in 1900, under date of February 26th, May 22d, 25th, and 28th, Juné 5th, and December 18th, are bristling with threats of litigation and “peremptory measures” unless complainant will cease to infringe the defendant’s patent. His hostile purpose, thus openly avowed, would naturally give color to his efforts to influence complainant’s customers. The correspondence introduced in evidence here must convince any candid person that some one has for several years carried on a vigorous campaign directed against complainant, and that it has been in large measure .successful. Numerous instances are given where orders that had been placed with complainant were countermanded because of the threats of Parmenter and *89other salesmen of defendant. The effort seems to have been successful so far as to disseminate a general fear among the trade and a general impression that an injunction suit had already been brought against Dittgen, so that it would be hazardous for any dealer to buy the complainant’s product. A naked denial is not persuasive against such a showing as is made by complainant’s proofs.
In fixing the responsibility for the wide-spread consternation of the trade, matters are simplified by the fact that there were but two competitors in the field. There was no one, aside from defendant, who is shown to have any motive for diverting the trade of complainant. For the same reason it was unnecessary for the defendant’s salesmen to assail the complainant by name. The work could be more safely and effectively done by vague insinuations, exciting fear of customers lest they subject themselves to an attack by defendant, armed and equipped with a number of patents. The studied instructions to salesmen, sworn to by them, indicate the skill with which the campaign was managed so as to leave no trace of malice in the letter book, or formal instructions.
It is the settled policy of the courts to restrain the illicit use of letters patent to maliciously injure the trade of competitors, whether the methods chosen are a multiplicity of suits brought against users to inspire terror and divert the trade (Commercial Acetylene Co. v. Avery Co. [C. C.] 152 Fed. 642), or circulars maliciously and persistently distributed among the trade threatening suit against all users of the alleged infringement, not for the legitimate purpose of giving notice of the patentee’s claims, but to terrify the customers of the alleged infringer. The same remedy is appropriate and may be necessary when the patentee avoids any adjudication and shuns the court entirely, thus denying all opportunity to attack his patents or to secure a ruling on the question of infringement, while at the same time he enforces his monopoly by a systematic crusade among the customers of his competitor, threatening suit and dire consequences unless his claims under his patent are respected.
Fetters patent should not be used as the Chinese formerly employed a horrible image to frighten an enemy. If such a campaign be skillfully conducted for a series of years, as seems to have been the case here, the competitor is helpless. His orders are countermanded, old customers desert him through fear of litigation, or demand bond of indemnity as a condition for placing orders. His business is melting away. Everywhere the trade is apprehensive of “peremptory meas. ures” if they buy goods of an infringer. He appeals to the patentee to bring suit, and offers to enter an appearance in any court having jurisdiction, but all to no purpose. Customers will not listen to his explanations or denials, and, unless he can get relief in a court of equity, his business, which represents 20 years of effort, may be entirely ruined by a competition which is malicious and unfair. These are, in brief, the considerations which underlie the ruling of Judge Seaman on the demurrer, as I understand it. See, also, Warren Co. v. Landauer (C. C.) 151 Fed. 130.
*90It remains to consider the plea of the statute of limitations, which was interposed by way of amendment after the close of the proofs, as to any alleged cause of action which arose during the period when the Racine Paper Goods Company was a copartnership, and antecedent to the formation of the defendant corporation.' The question arises in this way: "The Racine Paper Goods Company” was a copartnership up to January 4, 1902, when it was converted into a corporation, retaining the same name, carrying on the same business, inheriting the same assets, consisting of the same persons, and, unfortunately, continuing the same business methods. The corporation assumed all the debts and • liabilities of the copartnership. Both bill and answer, as originally framed, proceed upon the theory that the Racine Paper Goods Company had from the beginning been a continuing corporation. Proofs were taken on both sides covering the transactions anterior to 1902, without objection; but before the proofs were actually closed the real facts, as above stated, were disclosed. Thereupon complainant obtained leave to amend the bill. At the same time the defendant obtained leave by consent to amend the answer as above recited. The proofs show that the corporation assumed the liabilities of its predecessor, the partnership. The theory of the defense now is that the statute continued to run until the bill was amended.
Under the authorities the question is whether the amendment asserted a new cause of action not contemplated by the original bill, or whether it was a mere explanation or amplification of the original cause of action. The law is well settled by Judge Sanborn, speaking for the Court of Appeals of the Eighth Circuit, in Patillo v. Allen-West Co., 131 Fed. 680, 65 C. C. A. 508:
“The rule of law upon this subject is that an amendment to a petition which sets up no new cause of action or claim, and makes no new demand, but simply varies or expands the allegation in support of the cause of action already propounded, relates back to the commencement of the action, and the running of the statute so pleaded is arrested at that point; but an amendment that introduces a new or different cause of action, and makes a new or different demand, not before introduced or made in the pending suit, does not relate back to the beginning of the action, so as to stop the running of the statute, but is the equivalent of a fresh suit up.on a new cause of action, and-the statute continues to run until the amendment is filed.”
The following cases, cited by complainant’s solicitor, seem to bear out the doctrine above announced: Tremaine v. Hitchcock, 23 Wall. 518, 23 L. Ed. 97; Johnson v. Waters, 111 U. S. 640, 4 Sup. Ct. 619, 28 L. Ed. 547; Hardin v. Boyd, 113 U. S. 756, 5 Sup. Ct. 771, 28 L. Ed. 1141; Texas Pacific Ry. v. Cox, 145 U. S. 593, 12 Sup. Ct. 905, 36 L. Ed. 829; Richmond v. Irons, 121 U. S. 27, 7 Sup. Ct. 788, 30 L. Ed. 864.
The theory of the original bill was that the defending corporation was liable for the unfair competition practiced during the entire period. This theory was acquiesced in by both parties sub silentio, in both pleading and proofs. Prior to this amendment there is not in the record any suggestion that defendant’s liability was limited by reason of its former existence as a copartnership. When the fact of such former existence cropped out in evidence, the complainant saw fit to *91amend and state the facts of assumption by the corporation of all liabilities of the firm. It amounted to an amplification of the averments, which, perhaps, was not necessary, but certainly was proper; but it did not change the attitude of the parties, or bring in any new cause of action within the meaning of the rule. Under the original pleadings the identity and liability of the Racine Paper Goods Company was assumed throughout. The amendment suggests circumstantially the reason why such original assumption was just and equitable. The amendment to the bill was made by consent of parties to make the bill conform to the proofs. I am persuaded, therefore, that the running of the statute was arrested by the bringing of the suit.
Without reciting the evidence more in detail, I am driven to the. conclusion that defendant has been guilty of unfair competition and has thereby maliciously diverted and injured the trade of complainant; that against such unfair methods complainant, could obtain no adequate remedy in the courts of law; that he has sustained substantial loss in his business, and is therefore entitled to an injunction and an accounting as prayed.
An interlocutory decree will be prepared in accordance with this opinion.
