39 U.S. 448 (1840)14 Pet. 448
THE PHILADELPHIA AND TRENTON RAILROAD COMPANY, PLAINTIFFS IN ERROR,
vs.
JAMES STIMPSON, DEFENDANT IN ERROR.
Supreme Court of United States.
451*451 The case was argued by Mr. Coxe, and Mr. Southard, for the plaintiffs in error; and by Mr. J.R. Ingersoll, for the defendant.
457*457 Mr. Justice STORY delivered the opinion of the Court.
This is a writ of error to the judgment of the Circuit Court for the Eastern District of Pennsylvania, rendered in an action brought by Stimpson, the defendant in error, against the plaintiffs in error, for a violation of a patent right granted to him for a new and useful improvement in the mode of turning short curves on railroads.
A patent was originally granted to Stimpson, for the same invention, on the 23d day of August, 1831; and the renewed patent, upon which the present suit is brought, was granted on the 26th of 458*458 September, 1835, upon the former letters patent “being cancelled on account of a defective specification;” and the renewed patent was for the term of fourteen years from the date of the original patent. With the exception of the recital of the fact that the former letters patent were cancelled “on account of a defective specification,” and the statement of the prior date from which the renewed patent was to begin to run, the renewed patent is in the precise form in which original patents are granted.
At the trial upon the general issue, a bill of exceptions was taken to certain rulings of the Court upon points of evidence, to the consideration of which we shall at once proceed without any further preface.
The first exception taken is to the admission of the renewed patent as evidence in the cause to the jury. The patent act of 1832, ch. 162, sec. 3, under which this patent was obtained, provides, that whenever any patent shall be inoperative or invalid, by reason that any of the terms or conditions prescribed by the prior acts of Congress, have not, by inadvertence, accident, or mistake, and without any fraudulent or deceptive intention, been complied with on the part of the inventor, it shall be lawful for the Secretary of State, upon the surrender to him of such patent, to cause a new patent to be granted to the inventor, for the same invention, for the residue of the period then unexpired for which the original patent was granted, upon his compliance with the terms and conditions prescribed by the third section of the act of the 21st of February, 1793, ch. 55.
Now, the objection is, that the present patent does not contain any recitals that the prerequisites thus stated in the act have been complied with, viz. that the error in the former patent has arisen by inadvertency, accident, or mistake, and without any fraudulent or deceptive intention; and that without such recitals, as it is the case of a special authority, the patent is a mere nullity, and inoperative. We are of opinion that the objection cannot, in point of law, be maintained. The patent was issued under the great seal of the United States, and is signed by the President, and countersigned by the Secretary of State. It is a presumption of law, that all public officers, and especially such high functionaries, perform their proper official duties until the contrary is proved. And where, as in the present case, an act is to be done, or patent granted upon evidence and proofs to be laid before a public officer, upon which he is to decide, the fact that he has done the act or granted the patent, is prima facie evidence that the proofs have been regularly made, and were satisfactory. No other tribunal is at liberty to re-examine or controvert the sufficiency of such proofs, if laid before him, when the law has made such officer the proper judge of their sufficiency and competency. It is not, then, necessary for the patent to contain any recitals that the prerequisites to the grant of it have been duly complied with, for the law makes the presumption; and if, indeed, it were otherwise, the recitals would not help the case without the 459*459 auxiliary proof that these prerequisites had been, de facto, complied with. This has been the uniform construction, as far as we know in all our Courts of justice upon matters of this sort. Patents for lands, equally with patents for inventions, have been deemed prima facie evidence that they were regularly granted, whenever they have been produced under the great seal of the government; without any recitals or proofs that the prerequisites of the acts under which they have been issued have been duly observed. In cases of patents, the Courts of the United States have gone one step further, and as the patentee is required to make oath that he is the true inventor, before he can obtain a patent, the patent has been deemed prima facie evidence that he has made the invention. This objection, then, is overruled; and there was no error in the Circuit Court in the admission of the patent.
The next exception is to the refusal of the Court to allow a witness, Josiah White, to give a description of an invention which he had seen on the Mauch Chunk railroad, in 1827, which had a groove on one side, and run on the other on a flange for crossing, for the purpose of showing that the supposed invention of the plaintiff was known and in use by others, before the date of his patent. By the patent act of 1836, (which was applicable to the present point,) it is provided in the fifteenth section, that whenever the defendant relies in his defence on the fact of a previous invention, knowledge, or use of the thing patented, he shall state in his notice of special matter to be used in his defence, the names and places of residence of those, whom he intends to prove to have possessed a prior knowledge of the thing, and where the same had been used. The object of this most salutary provision is to prevent patentees being surprised at the trial of the cause, by evidence of a nature which they could not be presumed to know, or be prepared to meet, and thereby to subject them either to most expensive delays, or to a loss of their cause. It is incumbent on those who seek to show that the examination of a witness has been improperly rejected, to establish their right to have the evidence admitted; for the Court will be presumed to have acted correctly, until the contrary is established.
