Underwood v. Warren
Opinion of the Court
(orally.) The case of Underwood v. Warren and March is a suit for infringement of a patent. Most of the elements of this case have been heretofore considered, and the views of the court will be found in 20 Fed. Rep. 697.
All that is necessary to determine the question now presented can be expressed in a very few words. The Underwood patent, No. 205,-927, dated July 9, 1878, is a combination patent. The defendants use the Belan patent, of which they are the proprietors, which patent was issued November 18, 1876, numbered 186,225. Both of these patents are for ratchet-drills in connection with rails, or moro especially fish-plates on rails. The Belan patent consisted of two parallel bars, with clamps extending therefrom to hold them in position, and clamped to the railroad bar; and in order to operate the drill there was a movable block between the bars, with a horizontal screw running through it at the particular point where it was desired to boro the railroad bar. By screwing up horizontally the boring apparatus,
That is sufficient for a general description. It so happens that the proprietors of the Belan patent have everything that they had before, only they have chosen, in order to hold the sliding block in position more firmly than had been done under the original Belan patent, to bore vertically through it, and by means of a screw and a thumb-piece to hold it firmly i¡j position. Now, it is a most familiar principle in the law of patents that one who has a combination cannot sue for an infringement any person who does not use his entire combination. If he has chosen to insert in his combination elements that are unnecessary, his patent meets with very little favor. In this particular case, however, there is no infringement of his combination at all. The averment seems to be that by using a vertical screw with a thumb-piece, which is the most familiar mechanical element to hold a slide in position, the defendants have infringed this complainant’s combination. They have not used the combination, nor any new element of it.
The bill is dismissed. There is no infringement.
