Janin v. Curtiss, 45 App. D.C. 362, 1916 U.S. App. LEXIS 2698 (D.C. Cir. 1916).

Opinion

Mr. Justice Van Orsdel

delivered the opinion of the Court:

This is an appeal from the decision of the Commissioner of Patents in an interference proceeding awarding priority of invention to appellee, Glenn H. Curtiss, in an invention relating to hydroaeroplanes expressed in a single count, as follows:

“A hydroaeroplane comprising a main aeroplane supporting surface, lateral stabilizing aeroplane surfaces to create a difference of lift, a main water-borne central boat structure adapted to support the entire machine when on the water, and except for the aeroplane lift, constituting substantially the entire supporting element at all speeds so long as the boat structure is traveling in contact with the water, relatively small horizontal water balancing floats located below the supporting plane and beyond each side of said boat structure, said floats being located above the level of the boat bottom and provided with surfaces inclined downwardly and rearwardly, adapted to be acted upon by the rush of water when the machine loses its lateral equilibrium, and means for operating the stabilizing surfaces to create a difference of air lift.”

[364]*364■ The interference was declared originally between the application of appellant, Albert S. Janin, filed July 31, 1913, and the application of Curtiss filed August 22, 1911. The Janin application is a substitute for an earlier application filed January 26, 1911, and which is held by all the tribunals below to constitute a constructive reduction to practice of the invention in issue, therefore making Curtiss the junior party. To the satisfaction of all the tribunals of the Patent Office, except the Commissioner, Janin has established a date of conception of the invention as early as 1907, while all have agreed that' the earliest date that can be accorded Curtiss is May, 1910.

Curtiss claims, and has been awarded, actual reduction to practice in May, 1910, by the Examiner of Interferences and the Commissioner, while the Board of Examiners in Chief awarded him actual reduction to practice on January 26, 1911, the same date on which Janin filed his application in the Patent Office. We are in accord that Janin conceived the invention in 1907, and constructively reduced it to practice January 26, 1911. The case, therefore, turns upon the claim of Curtiss’s reduction to practice in May, 1910; for if, as held by the Board of Examiners in Chief, he did not reduce to practice until January 26, 1911, both'parties reducing to practice on the same date, and Janin being the first to conceive, he must prevail. McParland v. Beall, ante, 162 (January, 1916, term).

The case, therefore, turns upon the Curtiss alleged reduction to practice of May, 1910. It appears that in May, 1910, Curtiss experimented with a machine at Hammondsport, New York, of which photographs appear in the record and which is claimed to have embodied the subject-matter of the count in issue. As to this test, it is conceded by Curtiss that he only succeeded in driving the machine over the water at a rapid rate of speed, but did not succeed in making the machine rise from the water into the air.

It appears that after the experiment at Hammondsport, Curtiss dismantled his machine and constructed another, different in many particulars, which he shipped to San Diego, California, where, on January 26,1911, the day Janin filed his application, [365]*365he, for the first time, succeeded iu rising from the land and alighting upon the water, and rising from the water and alighting upon the land. If this was his earliest reduction to practice, as we have observed it was too late to avail him anything, in the light of Janin’s earlier conception.

It is important here to consider what is claimed by this count, in order to determine the sufficiency of the Hammondsport test. The count consists of five separate elements, as follows:

1. “A hydroaeroplane comprising a main aeroplane supporting surface.”
2. “Lateral stabilizing aeroplane surfaces to create a difference of lift.”
3. “A main water-borne central boat structure adapted to support the entire machine when on the water, and, except for the aeroplane lift, constituting substantially the entire supporting element at all speeds so long as the boat structure is traveling-in contact with the water.”
4. “Relatively small horizontal water balancing floats located below the supporting plane and beyond each side of said boat structure, said floats being located above the level of the boat bottom and provided with surfaces inclined downwardly and rearwardly, adapted to be acted upon by the rush of water when the machine loses its lateral equilibrium.”
5. “And means for operating the stabilizing surfaces to create a difference of air lift.”

While the contest here centers around the fourth element above stated, the whole issue must be considered in determining the question of reduction to practice. It is contended by counsel for Curtiss in the reargument, which was confined to the single question of whether’ or not the Hammondsport experiment by Curtiss amounted to a reduction to practice, that what the claim calls for is a machine capable of skimming the surface of the water at great speed, without capacity to rise from the water and fly. We are not impressed with this contention, nor do we think Curtiss’s own theory of the case substantiates it. Indeed, the third element of the claim above quoted clearly imp’ies a machine capable of rising from the water, in that it [366]*366describes tbe function of tbe boat as only of value when the machine is in contact with the water.

To determine whether this test was a reduction to practice of the invention for which Curtiss is now seeking a patent, it is important to consider his application. In the introduction to his specification he describes the invention as follows: “My invention relates to improvements in heavier than air flying machines, and has reference particularly to a machine adapted to alight on the water and rise therefrom by its own power. Some of the features of invention are, however, applicable to ordinary heavier than air machines.” This statement of the scope of his invention embodies in brief what he describes in his specification. His drawings disclose a flying machine, and of his fifty-one claims all but claim 38 call for a flying machine, and that claim calls for an aeroplane.

Curtiss has used the term “hydroaeroplane” as interchangeable with “hydro-machine,” “flying boat,” “aeroboat,” and similar terms, all referring to heavier than air flying craft capable of rising from the water, flying in the air, and alighting upon the water. That Curtis was aiming at this achievement in the Hammondsport experiment is clear, we think, from the circumstances and from his own statements. It may be suggested that what Curtiss said and did in May, 1910, in relation to this test, is of much more importance, as indicating what he had in mind, than his testimony in this interference as to what he was then attempting to accomplish.

Appearing in the record are extracts from publications admitted by Curtiss to be correct, extending from the Hammondsport experiment down through the San Diego tests, in which, he always refers to his machine as a hydroaeroplane. He was a pioneer in this art, and well knew the signification of the term and that it did not refer to a mere water-skimming device.
