Respondent brought this suit to recover compensation for the use and manufacture by and for the United States of a device alleged to be covered by respondent’s рatent No. 1,115,795 for an invention for the control of the equilibrium of airplanes. On the first hearing, the Court of Claims made special findings of fact and decided as a conclusion of lаw that respondent’s patent was valid and had been infringed by the United States and that respondent was entitled to compensation. Judgment was entered accordingly. 81 Ct. Cls. 785. On review by writ of cer-tiorari, this Court held that validity and infringement were ultimate facts to be found by the Court of Claims and, as these facts had not been found, the judgment was vacated and the case was rеmanded to that court with instructions to find specifically whether respondent’s patent was valid and, if so, whether it had been infringed.
United States
v.
Esnault-Pelterie,
The parties then moved in the Court of Claims for additional findings and that court amended its special findings by adding the following findings of fact:
“XLVIII. Claims 2, 5, 6, 7, 8, and 9 of the Esnault-Pelterie patent in suit are valid.
“XLIX. The three alleged infringing airplanes of the defendant аll possess the single vertical lever movable in every direction for controlling the lateral or longitudinal equilibrium of the airplane, connected to equivalent contrоlling surfaces having the same functional effects as those disclosed in the patent.
“Claims 2, 5, 6, 7, 8, and 9 of the Esnault-Pelterie patent in suit are infringed by defendant.”
*28 The court then entered an interlocutory judgment holding respondent entitled to compensation and directing that the court’s previous findings, as sftnended, together with its opinion as theretofore announcеd, should stand. 84 Ct. Cls. 625. Certiorari was granted.
Without its consent, the United States may not be sued for infringement of a patent.
Crozier
v.
Krupp,
The Act of March 3, 1863, c. 92, 12 Stat. 765, providing for suits against the United States in the Court of Claims, authorized appeals to this Court under such regulations as this Court should direct. See, also, Act of March 3, 1887, c. 359, § 4, 24 Stat. 505, 506. 28 U. S. C. 761. The rules first adopted provided for the finding of the facts by the Court of Claims and directed that “The facts so found are to be the ultimate facts or propоsitions which the evidence shall establish, in the nature of a special verdict, and not the evidence on which the ultimate facts are founded.” Rule 1,
“This Court uniformly has regarded the legislation and rules as confining the review to questions of law shown by *29 the record when made up as the rules direct. Bills of exception are not recognized in either the legislation or thе rules; nor is there other provision for bringing the evidence into the record or including therein the various rulings involved in applying to the evidence presented the rules which mark the line between what properly may be considered and what must be rejected. As long ago as Mahan v. United States,14 Wall. 109 , 111, this Court said of the rules that they could not be examined ‘without seeing that the purposе was to bring nothing here for review but questions of law, leaving the Court of Claims to exercise the functions of a jury in finding facts, equivalent to a special verdict and with like effect.’ ” 1
In a рatent case in the Court of Claims under the Act of 1910 the questions of validity and infringement are questions of fact. We have said that, for the purposes of our review in such a casе, the findings of the Court of Claims “are to be treated like the verdict of a jury, and we are not at liberty to refer to the evidence, any more than to the opinion, for the purpose of eking out, controlling, or modifying their scope.”
Brothers
v.
United States,
In the instant case, as pointed out in our previous opinion, there are 47 findings of fact preceding the findings of the ultimate facts, as now made, and by reference there are included 28 exhibits on 266 pages. These referencеs cover a number of patents claimed to be in analogous arts. From these, the Government seeks to establish that the device in question was not patentable over prior disclosures. But this is not a case where the Court of Claims has presented in its findings all the evidence upon which the ultimate facts are based so that it appears on the face of the findings that the judgment is necessarily wrong as matter of law.
United States
v.
Clark,
We may, of course, inquire whether thе subordinate or circumstantial findings made by the court below necessarily override its ultimate findings of fact and show that the judgment in point of law is not sustainable. But we have no such casе here. Nor is the case like that of a review by a Circuit Court of Appeals of decisions of boards, such as the Board of Tax Appeals, where the evidence is befоre the appellate court and the question is whether there was substantial evidence before the Board to support the findings made. Cf.
Phillips
v.
Commissioner,
The argument that the Government is precluded from obtaining the sort of review which is permissible in this Cоurt, when there is a conflict between circuit courts of appeals as to validity and infringement of patents, and the questions are submitted upon the evidence taken in the Distriсt Court, is unavailing, for the result is due to the procedure which has been established by the Congress for the determination of claims against the United States.
The judgment is
Affirmed.
is of the opinion that the findings do nоt show infringement of any valid patent; or that Appellee invented either a vertical lever or a universal joint or the combined use of a vertical lever and a universаl joint to control air planes or machinery; he believes the findings show that such means of control were in general use long before Appellee—five years after his оriginal application for a patent—filed an amendment asserting this claim. For these reasons he believes the judgment should be reversed.
