Lovell-McConnell Mfg. Go., Makers.

Miller Reese Hutchinson, Patentee.

[1] The bill alleges that by purchase, by acceptance, and by resale the defendant is a purchaser who has repeatedly and specifically acknowledged the validity of said patents, and that by reason of the premises the defendant is now estopped to deny the validity of said .patents. The bill also alleges that the defendant signed a supplemental selling license wherein it acknowledged its familiarity with complainants’ system of selling horns under conditional licenses. It is charged that the defendant has advertised and sold, and threatens to continue to advertise and sell, automobile horns, designated as the “Newtone” horn, made by another manufacturer, but embodying said inventions, in infringement of the rights of complainants.

The bill prays an injunction against manufacture, use, or sale of the complainants’ horns known as “Klaxon” and “Klaxonet” horns, of the kind purchased by the defendant from complainants, and also for an injunction against the use or sale of the “Newtone” horn or any similar horn at the same time that it uses, advertises, or sells the horn manufactured by complainants, and also against purchasing complainants’ horns without special written permission of the complainants, etc.

*132The license states that the instrument is licensed under conditions a.ssented to by purchase, that any. violation of these conditions revokes and terminates all rights and license as to this and all other instruments of makers in violator’s possession, and subjects violator to suit for infringement of patents without further notice. Paragraph 1 is in part to the effect that the instrument is licensed only when seller and buyer acknowledge the validity of the above-mentioned patents. Paragraph 2 in part provides that dealers may not sell to any one designated by the makers as objectionable; paragraph 4, that no license is granted for the purchase or sale by any one who has been notified that he is objectionable, etc.

The patents in suit have not been adjudicated, nor is general acquiescence shown. These complainants are prosecuting in the Eastern district of New York a suit upon these patents against the manufacturer of the Newtone horns, the Automobile Supply Manufacturing Company, wherein a preliminary injunction was denied. See Lovell-McConnell Mfg. Co. v. Automobile Supply Mfg. Co. (C. C.) 193 Fed. 658.

Under ordinary rules a preliminary injunction against the sale of “Newtone” horns would be denied upon the complainants’ showing. The complainants contend, however, that the defendant is estopped to deny the validity of the patents in suit, by reason of a condition attached! to the sale of complainants’ horns, known as “Klaxons” and “Klaxonets”; the condition being set forth in the first paragraph of the license above quoted. It will be observed that this license contains no direct provision restricting the defendant from dealing in other horns than those manufactured by complainants. The proposition that the defendant has estopped itself from contesting the validity of the patents in a suit to enjoin its sale of the product of other manufacturers is very doubtful. The condition as to acknowledgment of the validity of the patents seems rather a limitation of rights acquired in the use of a particular instrument than a general agreement with the vendor. Even should it be held that the relation established by purchase with knowledge of such conditions is strictly contractual, a point which requires further consideration in view of the reference in Henry v. A. B. Dick & Co., 224 U. S. 1, 32 Sup. Ct. 364, 56 L. Ed. 645, decided by the Supreme Court March 11, 1912, and to British Mutoscope & Biograph Co. v. Homer, 17 L. T. R. 213, there is ground for thinking that such contract must be confined to the specific subject-matter of the sale.

It is a peculiarity pi this form of license that by its terms the instrument itself is licensed. The license seems to be treated as appurtenant to a specific instrument identified by a number. If the licenses are several, and severally accepted, it seems reasonable to confine restrictions imposed upon the purchaser to dealings with the specific subject-matter.. The proposition that a purchaser of one of these instruments, with knowledge of the conditions, has thereby agreed to acknowledge the validity of the patents in suit for all purposes and in respect to other articles, is questionable for several reasons. Such an agreement by a purchaser may be altogether disproportionate to any *133consideration coming to the purchaser of a single instrument. The acceptance of this proposition would be likely to impose upon a purchaser by a catching bargain conditions which he did not appreciate.

As the license contains no express provision against the sale of any other horns, nor any express restriction of complainants’ ordinary legal rights in respect thereto, thp attempt to deprive the purchaser of one of complainants’ horns of the ordinary rights of sale and of ordinary rights of defense in respect to other articles, in the absence of evidence of full consideration for such a restriction, would have an aspect of unconscionableness and raise considerations of public policy. Pope Mfg. Co. v. Gormully, 144 U. S. 224, 238, 254, 12 Sup. Ct. 632, 637, 643, 36 L. Ed., 414, 420, 426.

The doctrine of acceptance of conditions upon the purchase ox articles with labels, notices, or indorsements thereon requires at law specific proof that the conditions were brought to the purchaser’s notice. In equity the chancellor should be satisfied, not only that the text was brought to the purchaser’s attention, but that the implications and indirect legal consequences of the agreement were understood, or at least were such as were fairly obvious to a purchaser in the ordinary course of trade.

Upon the motion for a preliminary injunction against the use of the “Newtone’’ horn, I am of the opinion that the complainants’ case is not aided by the contention that the defendant is estopped or has agreed1 not to contest the validity of the patents in respect thereto.

[ 2 j The contention that the defendant is bound by the acknowledgment of the validity of the patents gives rise to an inconsistency, when we consider the case in respect to the prayer for an injunction against the sale of “Klaxons” and “Klaxonets.” This contention seems to require us to assume that the license agreement is still in force. If abrogated by complainants, it can hardly be contended that the defendant is still bound by its terms. The complainants have an election to treat the license as still in force and to restrain a breach, or to consider it at an end. The difficulty in this case is that the bill involves inconsistent positions and not alternative positions. If the license is to be treated as in force, it is in force for all purposes, and the defendant cannot be treated as an infringer, but merely as one wrho has violated the terms of a contract still in force. The complainants may have grounds for their contention that the defendant is an infringer by reason of the sale of “Klaxon” and “Klaxonet” horns contrary to the terms of the license. Upon this point, however, there is doubt, in view of the facts. The complainants themselves cite cases showing that it is doubtful if the license has been abrogated and whether defendants can be treated as infringers. American Graphophone Co. v. Victor Talking Machine Co., 188 Fed. 428, 110 C. C. A. 308; Id. (C. C.) 188 Fed. 431. Until, however, the complainants shall elect definitely which right they will claim, it does not appear whether the case should proceed upon the theory of infringement or of violation of the terms of an existing contract. Though the court has power to grant alternative relief, it has no power to make an election for the complainants between inconsistent rights.

*134The case presents also a further question as to whether equity-should lend its aid to enforce the provision that a breach of conditions in respect to a single instrument shall revoke all rights as to other instruments in the violator’s possession. Forfeitures of this character are not favored by equity and will not be aided upon merely technical legal grounds. Furthermore, the complainants fail to show that in respect to sales of Klaxon or Klaxonet horns by the defendant the complainants are likely to. suffer such irreparable injury pending final hearing as to require a preliminary injunction.

Motion for a preliminary injunction is denied.
