18 F. Cas. 331 | U.S. Circuit Court for the District of Southern New York | 1857
Neither of the patents sued on in this case has been established on a trial, either at law or in equity. Nor have the exclusive rights which they purport to grant been acquiesced in by the public. Under these circumstances, to authorize the issuing of a preliminary injunction, the right of the plaintiffs must be clear and free from doubt, and the violation of right on the part of the defendants must be equally clear.
As it respects the Gazley patent, it is clear that, whatever rights were granted by the reissued one, are exclusively in the plaintiffs; that no one but the plaintiffs has any portion of either the legal or the equitable rights so granted; and that, to maintain the rights so granted, it is not necessary that there should he any other plaintiffs. With respect to the Denniston patent, it is not clear that the proper parties plaintiffs are before the court, to maintain a suit on that. The legal title to the Denniston patent is in Denniston, Remsen and Polhamus. The plaintiffs have no legal right to that patent. They have only a license to use it, and a covenant on the part of Denniston, Remsen and Pol-hamus, not to license any one else, and not to use the patent themselves. By the terms of the license, one-half of the damages to be recovered for the violation of the Denniston patent, is to belong to Denniston, Remsen and Polhamus. They, therefore, have an immediate and direct interest in any suit brought on the Denniston patent, and are not only proper parties but necessary parties, in any suit brought for an infringement of the Denniston patent.
The originality of the improvements which these two patents purport to secure to the patentees, is not so clearly established as to authorize the injunction prayed for..- After examining the proofs exhibited on the motion, it appears that there would be, at least, as much probability of doing irreparable mischief as of preventing it, by granting the injunction. To succeed, on a motion of this kind, the plaintiffs should make a stronger case.
Thei'e is one view of the case, as presented on the part of the defendants, which should incline a court to refuse a preliminary injunction. unless the right on the part of the plaintiffs, and the violation of right on the part of the defendants, are made clear and manifest. The defendants claim that they have a right to make the harness-saddles which they are • manufacturing, under and
