269 F. 707 | D.C. Cir. | 1921
The Commissioner of Patents refused to allow claims 1 to 5, inclusive, of Henderson’s application, on the ground that he was estopped from asserting them. Claim 1 is representative of the others, and is as follows:
A controller having positive and negative line terminals and terminals for the device to be controlled, an electromagnetic switch for connecting one of*708 the line terminals to one of the terminals for said, device, another electromagnetic switch for connecting the same line terminal to the other terminal for said device, a third electromagnetic switch for connecting the first terminal for said device to the other line terminal, and means for energizing said switches so that the first switch may close alone and the other two may he in closed position at the same time.
In April, 1908, one Gilpin filed an application on which a patent issued in August'of the same year. A little over a month afterwards Henderson filed his present application, in which claims 1 to 6 of the Gilpin patent were copied. He requested an interference with the latter which was declared. All the tribunals of the Patent Office decided against him, and this court affirmed the Commissioner’s decision. Henderson v. Gilpin, 39 App. D. C. 428. In February, 1913, the claims of the interference in Henderson’s application were finally rejected in accordance with the practice in the Patent Office.
Henderson waited almost a year and then presented claims similar to those before us. They were rejected on the ground,of res judicata. After much delay he again presented the disallowed claims, rewritten, however, so as to improve their terminology but without changing their substance. They were finally rejected and are now before us on appeal. The examiners in chief held that Flenderson was .estopped by judgment, and the assistant commissioner that he was estopped en pais.
In re Curtiss, 46 App. D. C. 183, relied on in this regard by Henderson, does not conflict with anything we have said. It was asserted in that case that the decision in an interference proceeding between Curtiss and one Janin had disposed of the questions then before the court, but the contention was rejected because the claims in the first case related to a flying machine capable of arising from the surface of the water, while in the case which the court was considering a skimming boat was the subject of the controversy. In other words, the subject-matter of the one case was different from that of the other. Not so here.
The decision of the Commissioner of Patents is right, and it is affirmed.
Affirmed.
