Campbell v. Mayor of New York
Opinion of the Court
The bill in this case sots up as valid letters patent No. 42,920, dated May 24, 1864, and granted to James Knibbs for an improvement in steam fire-engine pumps. The answer, among other things, alleges that the patent was void, “because that the said alleged- invention, with the knowledge, acquiescence, and consent of said inventor and pat-entees, had been in public use and on sale in this country for more than two years before the said alleged inventor’s or patentee’s application for their patent therefor. ” On traverse of the answer proofs were taken. The record shows clearly that the plaintiff’s counsel understood that consent and allowance of the inventor to sale or use of the invention more than two years before the application for a patent were necessary to defeat it; and that they accordingly directed their efforts to disproving consent and allowance to such sales and use as appeared, and not to meeting the evidence of sale and use otherwise. On final hearing sale and use were found, but without consent and allowance. These were held to be essential and controlling. The other issues were found for the plaintiff, and the patent was sustained. Campbell v. Mayor, etc., 20 Blatchf. 67, 9 Fed. Rep. 500. After the decisions in Andrews v. Hovey, 123 U. S. 267, 8 Sup. Ct. Rep. 101; 124 U. S. 694, 8 Sup. Ct. Rep. 676, settling that consent and allowance are immaterial, and that mere sale or use, not fraudulent or surreptitious, is sufficient, the defendant moved for leave to amend the answer, if necessary, to raise the question of sale and use alone, and for a rehearing. The amendment was held to be unnecessary to form an issue as to mere sale and use. A rehearing was had, and the case was re-examined. The application for the patent was filéd in the patent-office May 18, 1864. ,A sale of a steam fire-engine containing this invention, called the “Governor Hill,” by the Amoskeag Manufacturing Company, to the city of Concord, N. H., sent on the 28th day of April, 1862, was found; and this sale was held, in view of the decisions in Andrews v. Hovey, to he sufficient to defeat the patent. Campbell v. City of New Pork, 35 Fed. Rep. 504. The plaintiff now, before final decree signed, moves for leave to take proofs to show that the Governor Hill was built on an order from the city of Concord, and, although forwarded before, was not accepted till after May 13,1862; that this engine did not m fact contain this invention; and that putting the invention into any
“The second clause of the seventh section seems to us to clearly intend that, where the purchase, sale, or prior use referred to in it has been for more than two years prior to the application, the patent shall be held to be invalid, without regard to the consent or allowance of the inventor.”
Here is ,no reference to the construction, but only to purchase, sale, or use; and no reference to the first clause of the seventh section, which alone relates to the construction. The statement by the same learned justice in the opinion in the same ease in 123 U. S. 274, 8 Sup. Ot. Rep. Í05, that “the plain declaration of the second part of the section is that, where the purchase or construction of the machine or article took place more than* two years prior to the application for the patent, or where the use or sale by the person who so purchased or constructed the machine or article took place at a time more than two years prior to the application, the patent becomes invalid,” has been observed. But when that the second clause does not include construction in its declaration, and that use by the constructor more than two years prior to the application is referred to as one of the things that would defeat the patent, which would be defeated besides by the necessarily prior construction if that would have such effect, are noticed, the intention to hold and declare that construction alone of the patented article, without sale or use two years prior to the application, would defeat the. patent, does mot
The suggestion that the evidence is cumulative does not seem to be well founded. There has been in reality no evidence on the part of the plaintiff tending to prove the facts now sought to be established; but that it is either not newly-discovered, or was not so situated but that due diligence would probably have discovered it, is clear. If the right to have the case opened depended upon that, the propriety of a denial of the motion would be plain. But the issue to which the evidence is material is, on the part of the plaintiff, newly-discovered. The decision in Andrews v. Hovey has discovered it to those who took the testimony in his behalf, as well as to others. The law is not altered by that decision, but is declared to be different from what it was understood to be by them. The form of the answer appears to have aided that understanding. The case has been made to turn upon an issue of fact, to which the plaintiff has addressed no evidence. As the case now stands, the finding could not well be otherwise; but it is reached with a sense of insecurity that makes it quite unsatisfactory. The plaintiff and his counsel were in duty hound to know the law, and are liable to the consequences of misunderstanding it. and are not entitled to relief from the consequences while the misan-
