278 F. 313 | D.C. Cir. | 1922
From a decision of the First Assistant Commissioner of Patents, awarding priority to Kennington with respect to the invention of the issue, Bijur appeals.
The structure involved is described in four counts, illustrated sufficiently by count 1, which reads:
A starter for gas engines and the like, comprising in combination with a member operatively connected with the engine, a motor, a shaft driven thereby, a driving member adapted to engage and drive the engine member but normally out of engagement therewith, said driving member being mounted on the shaft and having screw-threaded engagement therewith whereby rotation of the shaft advances such driving member into engagement with the engine memner, and means for yieldingly stopping said driving member and thus permitting it to yield and cushion the shock of starting the engine member.
We held in Re Roberts, 49 App. D. C. 250, 263 Fed. 646, that the sole inventor was entitled to the benefit of the date of the joint application, on the theory that his application was an amendment of the joint one. It is a rule that “an amendment relates back to the time of the filing of the original petition.” Union Pacific R. Co. v. Wyler, 158 U. S. 285, 296, 15 Sup. Ct. 877, 882 ( 39 L. Ed. 983). From this it follows that Kennington is entitled to May 24, 1912, for constructive reduction to practice.
Bijur has not established that the decision of the Commissioner of Patents is wrong, and it is therefore affirmed.
Affirmed.
