Opinion

THOMPSON, Circuit Justice.

This is an application for an injunction to restrain the defendants from an infringement of what the complainant claims to be his patent right. The patent bears date on the 6th of November, 1826, and the right claimed is an improvement whereby to support ships in or on dock at the bilge, called “bilge levers.” The specification commences with stating that “The improvement claimed, specified and described, consists of a new and useful method 3 [979] of supporting the bilge of the ship before she leaves the water, while in fact inaccessible to any other sure support.” And after a description of the cradle or carriage upon which the vessel is to rest, and the application of the bilge levers, the specification sums up the improvement claimed as follows: “I describe the specific principle of my invention or improvement claimed to be patented and above described, to be the shoring or supporting vessels when on or in dock at the bilge, by means of levers of the second class, on each side raised to contact or bearing, and effectually propped or sustained.”

The bill alleges that this was a new and useful improvement, and that the complainant was the true inventor thereof, and that prior to the 6th day of November, 1820, he made and constructed, and put in readiness for operation, the said improvement, at the city of New York; and having obtained his patent therefor, the improvement was put in operation under the license of the complainant, and that he became possessed of the exclusive right and liberty of making, constructing, using and vending the same, &c.; and after setting out the infringement complained of by the defendants, the bill prays that they and their agents may be enjoined and prohibited from using the aforesaid improvement on the bilge levers which they or either of them have constructed, in whole or in part, since the 13th day of May, in the year 1S27. so ordered or directed to be constructed, and from completing any such bilge levers which they or either of them have at any time in part made or constructed, and from constructing and making hereafter any such bilge levers, without the consent ;ri writing of the complainant. 4

[980] The defendants hare not as yet put in their answers, but the motion coming before the court on notice, affidavits in support of and against the application have been introduced by the respective parties; and the motion is resisted on two grounds: (1) That if the improvement claimed be new, the complainant is not entitled to it as the first and sole inventor. (2) That it is not, in point of fact, new, but had been for some time in use in England before the complainant obtained his patent, and that it is in principle the same as the bilge blocks or wedges used in “Morton’s patent slip,” and for which’ a patent was granted in England in the year 1818.

The rules and principles by which this court is governed, in applications like the present, are laid down in the case of Sullivan v. Redfield [Case No. 13.597], Whether the patent is good and valid, so as ultimately to secure the right claimed under it, belongs to a court of law, in which the parties have a right of trial by jury. The jurisdiction exercised by a court of equity, in granting an injunction, is in aid of the common law, and should not be asserted when the right was doubtful; and that the court, in granting the injunctions, acts upon the assumption that the right has been infringed, or that little or no doubt exists on that point. When there has been an exclusive possession, for some considerable time, of the patent right, the court will sometimes, on the ground of possession, grant an injunction, without putting the party previously to establish the validity of the patent at law. But when the patent is recent, and any real doubts are entertained of its validity, the court will requiie that to be established at law before it will grant the patentee the benefit of an injunction. These are believed to be principles well settled in this country and in the English chancery, and to be founded upon the soundest rules of justice and equity, 5
