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
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 süch 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 th
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 1S27, 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 contrarv is established.
In the present case, there is no proof on the record that notice had been given according to the requirements of the statute, that White was to be a witness for the purpose above stated. Unless such notice was given, it is plain that the examination could not be rightfully had. The onus probandi is on the defendants to show it, and unless they produce the notice, the objection must fail. In point of fact, it was admitted by counsel, at the argument, that no such notice was, given. In either view, then, from the admission, or from the defect of the preliminary proof of notice in the record,' the exception is not maintainable.
The next exception is to the refusal of the Court to allow certain questions to be put by the defendants to John H. B. Latrobe, a witness introduced by the defendants to maintain the issue on their part. Latrobe, on his examination, stated, “ I know Mr. Stimpson
Now, (as has been already intimated,) it is incumbent upon those who insist upon the right to put particular questions to a witness, to establish that right beyond any reasonable doubt,,for the very purpose stated by them; and they are not afterwards at liberty to desert that purpose, and to show the pertinency or relevancy of the evidence for any other purpose, not then suggestéd to the Court. It was not pretended at the argument, that the evidence so offered was good evidence in chief, in behalf of the defendants upon the issue in the cause. It was res inter alios acta,’ and had no tendency to disprove the defendant’s title to the invention, or to support any title set up by the defendants; for no privity was shown between the defendants and the Baltimore Company. As evidence in chief, therefore, it was irrelevaht and inadmissible. The sole purpose for which it was offered, so far as it was then declared- to the Court, was to show, that the compromise with the Baltimore Company was not founded on any admission of the plaintiff’s right in the invention. Be it so; it was then inconsequential; for it certainly had no just tendency to disprove his right. If the compromise had been offered on the part of the plaintiff, for the purpose of establishing; his right to the invention, there is no pretence to say that it would have been admissible against.the defendants. In the converse case, it is equally inadmissible for the defendants.
But it is now said that the evidence was in fact offered for the purpose of rebutting or explaining certain statemer ?s made by one
The next exception is to the admission of the evidence of William A. Stimpson, Richard Catón, and George Neilson, as -to certain declarations, and statements, and conversations of the plaintiff, as to his invention prior to the date of his original patent; in order to rebut the evidence of the defendants, as to the invention or use by other persons of the same contrivance, before that date. The ob
The next and last exception is, to the rejection of the evidence of Dr. Jones, who was offered to prove that there were material differences between the patent of 1831, and the renewed patent of 1835, and to explain these differences.
No
doubt can be entertained that the testimony thus offered was, or might be, most material to
The mode of conducting trials, the order of introducing evidence, and the times when it is to be introduced, are, properly, matters belonging to the practice of the Circuit Courts, with which this Court ought not to interfere; unless it shall choose to prescribe some fixed, general rules on the subject, undér the authority of the act of Congress. Probably the practice in no two states of the Union is exactly the same; and then - ore, in each state, the Circuit Courts must necessarily be vested with a large discretion, in the regulation of their practice. If every party had a right to introduce evidence at any time, at his own. election, without reference to the stage of the trial’ in which it is, offered, it is obvious that the proceedings of the Court would often be greatly embarrassed, the purposes of justice be‘obstructed, and the parties themselves be surprised by evidence destructive of their rights, which they could not have foreseen, or in any manner have guarded against. It seems to us, therefore, that all Courts ought to be, as indeed they generally are, invested with a large discretion on this subject, to prevent the most mischievous consequences in the administration of justice to suitors; and we think that the Circuit Courts possess this discretion in as ample a manner as other judicial tribunals. We do not feel at liberty, therefore, to interfere with the exercise of this discretion; and, indeed, if we were called upon to say upon the present record, whether this discretion was, in fact, misapplied or not, we should be prepared to say, that we see no reason to doubt that it was, under all the, circumstances, wisely and properly exercised. It is sufficient for-us, however, that it was a matter of discretion and practice, in respect to which we possess no authority to revise the decision of the Circuit Court.
Upon the whole, we are of opinion, that the judgment of the Circuit Court ought to be affirmed with costs.
