American Diamond Rock Boring Co. v. Sutherland Falls Marble Co.
Opinion of the Court
These causes have been heard upon motions of the plaintiff for attachments for contempt for violation of the injunctions therein. The patent on which the suits are brought has been sustained for a continuously-revolving and progressive boring head, armed with diamonds for cutting rock, having a hollow central drill-rod, through which water is carried to the cutting diamonds, combined and forming a part of a machine to be suitably constructed for imparting the motion. The injunction restrains the use of machines made in the infringement of the patent during its term, which has now expired. The defendants are using machines made during the term of the patent, which carry boring heads and drill-rods made since the patent expired, according to its specifications. The patented devices are themselves a machine to be operated by other machinery, connecting them with propelling power not described in the patent.
The claims of the patent do not cover, nor show any attempt to cover, any combination of these cutting devices with the propelling machinery. A patent for a combination of new elements with old may secure the new elements by themselves as well as the combination. Sellers v. Dickinson, 6 Eng. Law & Eg. 544; Union Sugar Refinery v. Matthieson, 2 Eisher, 601. This is as much as any patentee of such a patent is entitled to hold. Prouty v. Ruggles, 16 Pet. 336. Here the other machinery is neither an element of the combination patented, nor an element patented by itself, and is not drawn into the monopoly at all. It infringed upon no right secured by the patent to make and use that during the term. That is not machinery made in infringement of the patent, although it was made to infringe the patent with. As the devices made according to the patent have been both made and combined since the expiration of the patent, the defendants are not shown to be using anything made in infringement of the patent.
Motions denied.
