36 App. D.C. 116 | D.C. Cir. | 1910
delivered the opinion of the Court:
This is an appeal from a decision of the Commissioner of Patents in an interference proceeding awarding priority of invention to the junior party, Louis L. Driggs, appellee here.
The subject-matter of the invention is sufficiently described in the claims of the issue, as follows:
“1. In a semi-automatic gun, the combination with the gun body and cradle, of one or more recoil cylinders, a main bolt journaled to the breech of the gun, breech mechanism operated by said main bolt, means on said main bolt for operating same automatically, a cylinder rigidly attached to said gun exterior to the recoil cylinder; a piston, piston rod, and a spring under compression, all mounted in said cylinder and all recoiling with the gun, a connection between said piston and said main bolt, and mechanism operated on counter-recoil for opening the breech against the action of said spring.
“2. In a semi-automatic gun, the combination with the gun body and cradle, of one or more recoil cylinders, a main bolt journaled to the breech of the gun, breech mechanism operated by said main bolt, means on said main bolt for operating same automatically, a cylinder rigidly attached to said gun exterior to the recoil cylinder; a piston, piston rod, and a spring under compression, all mounted in said cylinder and all recoiling with the gun, means for varying the compression of said spring, a connection between said piston and main bolt, and mechanism operated on counter-recoil for opening the breech against the action of said spring.”
Charles Prosper Eugene Schneider filed his application November 14th, 1905; Driggs on April 13th, 1906. Schneider depends entirely for conception and reduction to practice upon the filing date, August 3rd, 1905, of his application for a Erench patent. If, therefore, Driggs’s evidence shows conception, followed by diligence or reduction to practice prior to that date, he must prevail. The Examiner of Interferences
At the outset it is well to note the distinction between this case and cases involving a small and easily changed device or structure. It is also well to bear in mind the fact that much of Driggs’s testimony and that of his witnesses related to transactions with the government, and that such testimony might easily have been disproved if not correct. In other words, the surrounding circumstances in such a case as this are entitled to greater weight than in an ordinary case. Appellant having taken no testimony in rebuttal, Driggs’s evidence must be accepted, unless it is inherently unreasonable or lacking in completeness. Let us here subject it to a brief analysis.
Driggs himself, whose testimony each of the tribunals of the Patent Office has found to be full and definite, studied theoretical and practical ordinance and gunnery at the United States Naval Academy, resigned in 1889 to go into the manufacture of ordnance, and has,- since that time, been actively engaged in designing ordnance. Prior to his work on the gun here
No one. was called by Mr. Driggs to testify as to the test made in Pennsylvania, except the secretary and treasurer of the company who possessed no technical knowledge of the gun structure. This witness saw the gun fired, but his testimony on the question of reduction to practice is of no value. The witness, however, does testify very specifically and satisfactorily' as to the time when the gun was completed, tested in Pennsylvania, and shipped to Washington to be tested at Indian Head. Freight vouchers were produced which corroborated the witness in detail. Driggs also produced the company’s mechanical engineer, a Mr. Hughes, whose testimony is' also-direct and satisfactory. Mr. Hughes first visited the com
It is insisted, by the appellant that Driggs should have called as witnesses one or more of the officers who witnessed the tests at Indian Head, should have introduced further evidence as to his conception and disclosure of the invention, and that as the case stands he has not proven either conception, disclosure, or reduction to practice. In advancing these contentions, it
We have no greater difficulty in disposing of the second contention. It is established beyond question that the gun, which was constructed by the Driggs Company prior to June, 1905, and tested at Sharon, Pennsylvania, was shipped to the government proving ground at Indian Head, Maryland, late in June, 1905, there thoroughly tested, and, as a result of this test, was adopted as the standard gun of this type; that the same gun was taken back to the Navy Yard at Washington and used as a model for the other guns which the government ordered; that it embodied the elements and each of the elements of the issue. Not a word of tesitmony was introduced by appellant, and yet we are asked to find that the fact that the government fired this gun 100 times, adopted it as its standard, ordered over 150 more, did not amount to a reduction to practice. To so find would be equivalent to a finding of negligence or incompetency against the Navy Department. The fact that this gun, as the result of a competitive test, was adopted by the Navy Department, is, in our view, the best possible evidence of reduction to practice. At the time this testimony was taken the gun was public property, had been under the exclusive control of government officials since a time anterior to appellant’s foreign filing date, upon which he relies for disclosure and constructive reduction to practice. If, therefore, that gun had been changed in any way, or if it had not embodied all the elements of the issue, appellant could very easily have brought out or established the real facts. He has not done so, and we are not dis
The decision of the Commissioner was right, and is affirmed. The clerk will certify this opinion as by law required.
Affirmed.
