101 F. 131 | 2d Cir. | 1900
That part of the order appealed from restraining the defendant, during the pendency of the action, from selling any incandescent mantles “except such as shall he shown to have been coated by others,” can only be justified upon the theory that the patent for infringing which the suit was brought was a patent for a product or manufacture, and not one for a process. If it was a patent for a process, it would not be infringed by selling the product, and no conditions should have been annexed to the exercise of the vendor’s rights. The broad proposition that the vendor of a product whicii has been made in infringement of a patented process is an infringer, or liable to any extent to the patentee, is untenable and does not require discussion. The patentee’s remedy is against the manufacturer. Merrill v. Yeomans, 94 U. S. 568, 24 L. Ed. 235.
“(1) The herein-described improvement in strengthening incandescent mantles, consisting in coating the completed mantle with paraffin, or other suitable material, substantially as set forth. (2) In the manufacture of incandescent mantles, the method of forming said mantles, which consists of first stretching the impregnated knitted mantle upon a mandrel, then burning the mantle, then shaping the mantle against the mandrel by means of a blowpipe flame, and finally coating the mantle with paraffin, or other similar material, substantially as set forth.”
The first claim covers merely the final part of the process, and the second covers the entire process. It is unfortunate that an invention of such great merit and value is not adequately protected by the claims of the patent; but so it is, and any person is at liberty to vend or use the invention without accountability to the patentee, except he also be the manufacturer or a contributory infringer. The order must, as to the part referred to, have been inadvertently made, and should be modified by eliminating that part
