Nathan Manuf'g Co. v. Craig

Colt, Circuit Judge. This bill is brought under section 4918 of the Revised Statutes, which provides that, where there are interfering patents, any person, interested may have relief against the interfering patentee, and all parties interested under him, by suit in equity against the owner of the interfering patent, and the court may adjudge either of the patbnts void in whole or in part. The bill alleges the issue of letters patent 337,500, dated March 9, 1886, to Kaczander and Ruddy, and of the letters patent No. 357,931, dated February 15, 1887, to Kaczander, and that the patents are vested by assignment in complainants. It further alleges the issue of letters patent No. 398,583, dated February 26,1889, to the defendant Warren H. Craig, and that said patents are interfering patents. The answer denies that said patents are interfering patents, and avers that, if there is an interference, Craig is the prior inventor. Upon a bill of this character, the first question to determine is whether the patents are interfering patents; and, if this is shown, the next question is, who is the' first inventor? The invention which a man patents is that which he claims, and patents do not interfere, unless they claim the same invention in whole or in part. Upon suits brought under this section, it has, therefore, been repeatedly held, until it has become well-settled law, that two patents interfere, within the meaning of this section, only when they claim, in whole or in part, the same invention. Gold & Silver Ore Separating Co. v. United States Disintegrating Ore Co., 6 Blatchf. 307-310; Reed v. Landman, 55 O. G. 1275; Morris v. Manufacturing Co., 20 Fed. Rep. 121, 122; Pentlarge v. Bushing Co., Id. 314; Electrical Accumulator Co. v. Brush Electric Co., 44 Fed. Rep. 602-605; Mowry v. Whitney, 14 Wall. 434-440. It is apparent upon examination that the claims of the Craig patent do not cover the mechanism described in the claims of the two patents owned by the complaipants; in other words, there are no “interfering claims” here, and this .position is substantially admitted by the complainants. Under these circumstances, I do not deem it necessary to enter into a comparison of the claims of these different patents. The complainants’ position seems to be that, in a bill of 371 tins character, the court may go outside and beyond the claims of the interfering patents, and consider generally the two inventions or structures, taken as a whole; and complainants cite, as an authority upon this point, the case of Garratt v. Seibert, 98 U. S. 75. In that case, however, the answer did not deny, but rather admitted, an interference of the patents, and it is therefore not an authority against the general doctrine which the courts have laid down upon this point. Bill dismissed.
