delivered the opinion of the Court:
On February 28, 1896, the present applicant, William T. Barratt, filed an application in the Patent Office for letters patent for a certain alleged invention claimed to have been made by him in needle cylinders for knitting machines.
“There is no broad line of demarcation between the exercise of mechanical ingenuity and that of the inventive faculty, and it is not always easy to tell where the one begins and the other ends. In the meager record of the case before us that difficulty is enhanced by the fact that very much is left for us to conjecture as to the condition of the art to which this alleged invention appertains at the time when the improvement was devised, and the diagrams introduced into the record do not remove the difficulty. Without entering into details we think that, while the appellant’s device commends itself to our favorable consideration, and may upon a judicial investigation wherein proof is more fully supplied and the condition of the art more clearly set forth, be found entitled to the merit of patentable novelty, we should hesitate in this ex parte proceeding to reverse the concurrent decisions of all the tribunals of the Patent Office, which we think should not be done except in a very clear case. At most there is but a suspicion that the appellant’s device may rise to the dignity of invention. Upon full proof in a court of equity that suspicion may possibly become certainty. We have not now the data before us that would warrant us in so regarding it in this proceeding.” 11 App. D. C. 177.
Thereupon the applicant, instead of resorting to a bill in equity, as he was authorized by law to do, filed a new application in the Patent Office for the same subject matter that had been set forth in his previous application, but with more full and ample specifications and drawings, a more thorough showing of the prior condition of the art, and evidence bearing on the patentability of the alleged invention. And it is this second application that is now before us upon appeal from the Commissioner of Patents, after rejection by all the
While the rules that govern the finality and conclusiveness of adjudications at the common law do not apply, in the strict sense, to administrative or quasi-judicial action in the Executive Departments of Government, yet in administrative action, as well as in judicial proceeding, it is both expedient and necessary that there should be an end of controversy. Sometimes, the element of finality is inherent in the nature of the action taken; as, for example, when letters patent have been granted, they may not be recalled, and the rights of the parties holding them again investigated. Where rights have become vested as the result of legitimate executive action, such action is necessarily final, and it is not competent thereafter for executive action to divest them, either by way of a review of the proceedings or by any new proceedings instituted with that view. Especially is this principle applicable to the proceedings of the Patent Office, which are so nearly akin to judicial proceedings as to be most appropriately designated as quasi-judicial. In fact, it is only by regarding these proceedings as substantially judicial that we can sustain the validity of the legislation which authorizes appeals to this court from the decisions of the Commissioner of Patents.
The force of this position is appreciated by counsel for the applicant, who seeks to sustain the course here pursued upon the theory that the new application is substantially different from tbe previous one, and that it is made in compliance with the spirit, if not with the letter, of the opinion of this court in the former case. That opinion suggested to the applicant to file a bill in equity, as he was authorized by law to do, not a new.application, for which there is no warrant in law. The new application does not make a different case. The case is the same precise case. The subject matter of invention is the same. The claim is the same. Only the specifications and drawings are more full; and the state of the art at the time of the alleged invention is more fully and satisfactorily shown. But all this, which might well have been adduced by way of amendment or otherwise in the original proceeding, or which might have been shown under a bill in equity, at the utmost amounts to no more than a clearer and better declaration or additional proof of the alleged invention. It does not make any new case; and it does not justify the filing of any new application.
The applicant seeks to support his contention by reference to the case of Tilghman v. Proctor,
Illustration of the subject may be found if we suppose that, after the refusal of the primary examiner to consider the case upon its merits, or after the refusal of the Commissioner in the first instance to give the case such consideration, application was made for a writ of mandamus to compel entertainment of the case. Could such writ of mandamus be maintained? Undoubtedly if the applicant for a patent had a right to prosecute a second application after the determination of the first adversely to him, there would be a corresponding duty on the part of the office to hear and determine the case; and beyond question, the performance of such duty could be enforced by mandamus. But it would be a complete answer to the writ, if the return of the respondent showed that he had already fully performed what he was required to do, as it certainly would in such a case.
But it is argued that, although the Patent Office, in view
In what we have said we do not desire it to be understood that the Patent Office may not, if it thinks proper so to do, entertain and adjudicate a second application for a patent after the first application has been rejected. What we decide is, that it is not incumbent upon the office as a duty to entertain such applications, and that, if it refuses to entertain them, it has a perfect legal right so to do. An applicant is not legally aggrieved by such refusal.
It follows that the decision of the Commissioner of Patents in the present case must be affirmed; and it is accordingly so ordered.
The clerk of the court will certify this opinion and the proceedings in this court to the Commissioner of Patents according to law.
