This аppeal is taken from the judgment rendered by the District Court pursuant to and in accordance with its opinion which is reported at
The trial court said
On this appeal it is contended for appellants for reversal (1) that the evidence was insufficient to sustain the judgment; (2) that the plaintiffs failed to present to the court all the evidence that was before the Board of Interference Examiners, and introduced evidence not submitted to the Board and thereby made it impossible for the court to adjudicate priority of invention contrary to the award of priority made by the Board; (3) that the Jorgensens lost any right to patent they may have had by delay in applying for patent, and (4) that the complaint before it was amended failed to state facts necessary to confer jurisdiction, and that the amendments erroneously permitted to be made after the six month period fixed by the statute for commencement of the action did not cure the defect or confer jurisdiction.
In a reply brief for appellants a further argument is here presented to the effect that the device relied upon by the Jorgensens аnd claimed by them to have been reduced to practice prior to the date of Ericson’s application as found by the court was in fact merely an indefinite and unstated combination of insufficiently described elements and did not embody the subject matter of the count in interference. But it appеars from the record that the issue thus sought to be raised was not presented to, tried or decided by the trial court. As hereinafter stated, we hold that the bill in equity as amended presented a case within the jurisdiction of the court brought under Section 4915 to obtain authorization for patent upon review and avoidаnce of the decision of the Board of Interference Examiners which determined that the Jorgensens had not reduced their identified device to practice prior to Ericson’s application date. The case in the Patent Office arising out of Jorgensens’ and Ericson’s patent applications had gone in due course of Patent Office proceedings to the Board of Interference Examiners from decisions and *183 rulings of the primary examiner by which the questions of invention, embodiment thereof in claims and the common subject matter of the claims were established for the purpose of the interference. Although the opinions of the Board do not expressly so declare, it is evident from their context that the Board accepted the rulings that preceded the interference and tried out and decided the question of priority. They show in reference to one element of “Jorgensen et al.” (a so-called “kicker”) that Ericson “moved during the motion period” “to dissolve the interference on the ground that Jorgensen et al. (1) did not disclose the subject matter of the count” but the Board agreed with the position of the primary examiner on that matter and it records no other objection raised by Ericson to any failure of “Jorgensen et al.” to embody the subject matter of the count in interference. The “kicker” was not disclosed in the device exhibited and relied on in the civil action.
In that action the plaintiffs’ evidence went to show that the Board decided erroneously and defendants sought to sustаin its decision in their favor but neither party at any stage of the trial questioned the validity of the action of the patent office declaring the interference. Although the findings prepared by counsel to reflect the court’s opinion -included a finding that Jorgensens’ “choke controlling mechanism embodies thе subject matter of Count one” of the interference, the appellants have not assigned that finding as error in their appeal.
We think the trial court properly recognized the validity of the interference for the purposes of the suit in the absence of issues in respect to it and limited its decision tо the issue of priority litigated before it.
We need not and do not hold that in an action brought under Section 4915 the court may never inquire into and determine that neither party is entitled to a patent for want of invention or for want of valid or appropriate claim. Morgan v. Daniels,
Our review is accordingly limited to the matters litigated and decided in the trial court.
Opinion.
(1) As to the sufficiency of the evidence. We think the evidence that the Jorgensens made their automatic choke device and attached it to their Studebaker car with Stromberg carburetor and tested it out and fоund that it worked satisfactorily through the winter of 1929 and 1930 fulfills the requirement set forth in the opinion of this court in Larson v. Crowther,
But consideration of all contentions made fоr appellants on the evidence has not persuaded th'at any facts or circumstances were shown sufficient to raise substantial doubts of the truth of the proof presented that Jorgensens did conceive and made the device they brought into court; that they attached it to a Stromberg carburetor on a Studebaker car sometime before Christmas 1929, and ran the car with it through the winter of 1929-1930. That during that time they demonstrated the device and its operation to witnesses who were especially qualified to and did understand and appraise it and that it worked successfully. We find none of the so called documentаry evidence relied on by defendants to be unequivocal or demonstrative that the Jorgensens thought their device would not work or that they abandoned it. We need not ignore that automatic chokes remain without universal adoption in 1949, twenty years after Jorgensens produced theirs. An absoj lute of perfection is not involved. The evidence justified the certain conviction arrived at by the trial court that the Jorgensens conceived and reduced their device to practice long prior to Ericson.
(2 & 3) The points made for appellants that all the evidence taken before the Board was nоt brought before the court and that the court heard evidence not submitted to the Board and that the Jorgensens lost their right to a patent through their delay in applying for it, appear to be without merit. The provisions of the statute as to the testimony to be received and considered on the trial of an аction under Section 4915 are not ambiguous and in our earlier case of Larson v. Crowther, supra, the decision adverse to that of the Patent Office was arrived at largely because of the testimony brought before the court not previously presented to the Board. The Jorgensens did not delay unduly in apрlying for patent. Soon after reducing their invention to practice they contracted to have patent applied for and for manufacture and commercial exploitation and- upon failure of the other contracting party to proceed they took other steps to the same end and actually applied well within two years. In the years 1934 and 1935 some three or four hundred thousand units of their device, substantially like the original, were turned out.
(4) As to the jurisdiction: It appears that in drawing the bill in equity herein a mistake was made in describing the statute, Section 4915 under which it was brought, in that the pleading failed to inсlude reference to the amendment to that section of 1939 or the allegation contemplated by that amendment that the plaintiffs were “dissatisfied with the decision of the Board of Interference Examiners.” The bill set out that the Board had tried out the interference and that it had decided priority in favor of Ericson and against the plaintiffs, whereas the plaintiffs were in truth the first and prior inventors entitled to priority over Ericson. It alleged that the Commissioner of Patents had refused them a patent and prayed that he be authorized to issue one.
We think it was clearly to be inferred from the allegations of the bill as it was filеd that the complaint or dissatisfaction of the plaintiffs was on account of the decision of the Board awarding priority of invention to another when in truth the plaintiffs were entitled, and so considered it stated a case under the amended statute *185 within the jurisdiction. The ruling of the -court permitting amendment to make that meaning certain was not erroneous.
On the whole record we find no error to justify reversal and accordingly affirm the judgment.
Affirmed.
