After careful analysis of the bill of complaint, the answer of defendants Ballagh, *701Armington, and Armite Laboratories, and the affidavits on lile, I am of the opinion that a preliminary injunction should issue herein enjoining the defendants, their agents, servants, employees, and attorneys, and those in active concert or participating with them, pendente lite, from making, using, or soiling, or causing to be made, nsed, or sold, or threatening, advertising, or offering to make, nse, or sell, or contributing to the making, using, or selling of any processes embodying or containing the invention patented or claimed in and by United States reissue letters patent No. 17,323, and specifically, the process and/or product called “Armite Are-wold,” and it is so ordered. Said preliminary injunction to issue upon the giving and filing by plaintiff of a good and sufficient bond in the sum of $3,000. Tho bond may be approved by a judge of this court or the clerk thereof.
In amplification of the foregoing order, it is thought proper to state that the proof adduced warrants protection to the plaintiff against the manufacture, vending, and sale of the process and product “Armite Arcweld” by the issuance of a preliminary injunction to operate pendente lite herein.
It is true that the rule is well established that except in extraordinary eases, a preliminary injunction should not issue in a patent infringement suit where there has been no adjudication of the validity of the patent. The record here presents an extraordinary situation. The patent is presumed valid and the proof shows that the defendants or some of them have been in close business relationship with plaintiff in the marketing of the product “Blackor,” which is a process and product manufactured by plaintiff and embodies the invention patented by tho patent in suit. Moreover, the evidence shows that upon severance of a business relationship with plaintiff, the defendants commenced dealing in “Armite Arcweld,” which according to the evidence is clearly within claims of plaintiff’s patent. The answer of defendants is merely a denial o’f the allegations of the bill of complaint, and the only justification in the record for the manufacture and sale of “Armite Arcweld” is a statement in one of the affidavits that some person represented to defendant that he had produced and tested a compound for hard surfacing of metals that would not infringe any existing patent, and who cited an expired English patent which described tbe use of Tungsten as a hard surfacing substance when applied by fusion method, and that therefore any subsequent patent covering the application of Tungsten would in his opinion bo void for want of invention. It seems to me that upon such a meager showing in tho face of tho proofs of the issuance of the patent in suit and the acquiescence of the public in its validity, as well as the activities of the defendants in marketing tho product “Amite Arcweld,” every ground for which a preliminary injunction on an unadjudicated patent has been granted and-approved, exists in this case.
