The complainant filed its hill, seeking to restrain infringement of letters patent and alleged acts of unfair trade. The defendant Creamery Package Manufacturing Company, after answering the bill, presented its petition herein, charging that, cotemporaneously with the institution of this, another suit, identical as to parties and subject-matter, was begun by complainant in the District Court for the Northern District of Illinois; that since the commencement of such suits complainant, through its attorney, for the purpose of injuring and destroying defendant’s trade in vacuum cleaners (charged to he in infringement of complainant’s patent), has by means by threatening- letters, advertisements, and circulars attempted to influence past or prospective customers of defendant from using or purchasing its product.
The petition specifies letters written to one Long, at Akron, Ohio, who had purchased from defendant, notifying him that complainant claimed such machine to infringe complainant’s device, that the above-mentioned suits had been instituted, that complainant would fully protect its rights, that users as well as makers of infringing articles are liable, and requesting said Long to desist from further use and to settle with complainant. A second letter was sent, reiterating the substance of the first, but further notifying him that, unless by a time specified he desisted using such machine, suit for infringement would be instituted against him. Such suit was in fact begun, and defendant charges that the bill therein is identical with that herein. It is averred generally that the suits thus begun and threatened, and the letters sent, Were not intended for the protection of complainant’s legitimate rights under its [latent, hut to annoy and harrass defendant.
*54The complainant, its exceptions to the-jurisdiction.of the court having been overruled upon the authority of Warren Featherbone Co. v. Landauer (C. C.) 151 Fed. 130, Commercial Acetylene Co. v. Avery Portable Lighting Co. (C. C.) 152 Fed. 645, and. other cases, demurred in part to, and answered the remainder of, the petition; and the matter was heard upon these pleadings and affidavits presented by the parties.
The answer to the petition specifically and positively denies that the suits were instituted, or the circulars and letters sent, for any purpose except the protection of the complainant’s rights under its patent, or threats to bring other suits against users or dealers, excepting that two at Akron, Ohio, were so notified, which suits, however, have not been brought, because one of such users had given assurance that he did not in fact use or purpose to use the alleged infringing device, and, against the other, suit has been deferred pending the outcome of suits already pending. Such answer further responds to the allegation of the petition respecting the sending of other threatening^ letters, and the insertion of an advertisement in the Akron, Ohio, paper by denying'specifically that any letters whatsoever had been sent, except those referred'to in the petition and those admitted in the answer, and that the advertisement in the paper contained nothing more, than a fair and legitimate statement of complainant’s claims respecting infringement of its patent.
Upon the hearing, no proofs were introduced to meet the denials and explanations of the complainant’s answer to such petition; and the only question for determination is whether the admitted facts will sustain clearly any inference that complainant has been guilty of conduct such as is in general terms charged to it. We assume that complainant is before the court to be dealt with in respect of any conduct disclosing a purpose to harrass and annoy the defendant; but the burden rests upon the latter to show that the alleged conduct of the complainant is not reconcilable solely with the purpose of enforcing and protecting its legal rights as a patentee. The pleadings and the proofs, as they now stand in this case, fall short of this in two particulars:
First. The letters set out in the petition, and admitted to ’have been sent, do not disclose anything inconsistent with the assertion by the complainant of its legal rights, and possibly its duty to notify persons of its claims of infringement. Such letters are unmistakable in their terms, contain no misstatement of fact, and convey to the sendee no information which a patentee is not justified in sending, not only to the trade, but particularly to those whom it conceives to be trespassing upon its rights.
Secondty. For the purpose of this application it must be taken as true that the complainant did not in fact send out letters or circulars other than those specified in its answer; and in this respect, therefore, the claim of the petitioner as to the extent of complainant’s conduct in circularizing tbe trade — and from which would be drawn the inference of a desire to oppress — fails.
The authorities, while recognizing the power of the court to deal with a situation such as that claimed by tbe defendant, uniformly'declare that unfairness and an intentional disposition unnecessarily to *55injure another’s business are at the foundation of the right, in a suit of this kind, to invoke the protection of the court through an injunction against the complainant. The Circuit Court of Appeals of this circuit has given its views in the following language:
“Undoubtedly one claiming that his patent is being infringed should take steps to advise the public of his rights as provided by statute; provided, however, that if it is made to appear that under the pretense of so doing he is pursuing a course which is calculated to unnecessarily injure another’s tmsinesss, and with the.plain intention of so doing, his conduct will be deemed malicious, and he brings himself within the rule of law obtaining in cases of unfair competition in trade, and subject to injunction.” Per Kohlsaat, J., Racine Paper Goods Co. v. Dittgen, 171 Fed. 631, 96 C. C. A. 433.
As indicated, the case, as it now stands, is not brought within the letter nor the principle of the rule thus stated. The complainant has given an explanation of the institution of suits both at Milwaukee and Chicago, which, in the absence of clear proof to the contrary, justifies its conduct. It has pointed out the necessity of acquiring jurisdiction over all of the defendants, and that this is impossible in a single suit because of the diversity of residence of such defendants. It has met squarely and unequivocally the accusation respecting the malicious sending of threatening letters and circulars, and the defendant petitioner has failed to produce the necessary proof; and it seems to me that, even though the zeal of the complainant may give rise to a suspicion respecting the singleness of its purpose to protect its legal rights, the power of restraining by injunction its right to institute further suits, or to further advise alleged infringers of its rights, should not be exercised, except upon a showing which, as in an original proceeding., is sufficiently clear to justify resolving doubts against the complainant.
For these reasons, and because the necessary proofs are lacking, the application of the defendant will be denied; and an order may be entered accordingly.
