No question of law is here involved, and the exr piration of the senior and controlling of Weber’s patents takes away from this suit all professional interest, except as it completes a protracted history of litigation. Our only duty is to interpret the patents as the senior patent was interpreted by the Supreme Court, and in so doing correct our own decisions, if correction be needed'.
Comparison of the “Connecticut” case (263 Fed. 583) with the Freeman Case in the Third Circuit (262 Fed. 769) will, we think, show with entire clearness that it was admitted by everyone that the sleeve and cap of the socket defined by the first and fourth claims of the senior patent must in locking be moved “telescopically.” This circuit held that infringement existed if the longitudinal sliding movement of *415Weber had' added to it a rotational movement or component; whereas the Third Circuit held that the word “telescopically” limited said claims to an arrangement involving a straight sliding movement and nothing else.
The plaintiff here and defendant in the Third Circuit having obtained review of the Freeman decision by certiorari, the Supreme Court held in terms that it fully agreed with the Third Circuit in that—
“the prior art, the file wrapper and the [junior patent here in suit] required that the expressions in the fourth claim ‘telescopically received’ and ‘telescopically applied’ must be restricted to a direct longitudinal movemerit or thrust of the sleeve into the cap, and that for this reason the construction of [Freeman Company] requiring a rotary movement to render it effective, does not infringe that of” the plaintiff herein.
The highest court also specifically held that Weber had, in order to avoid infringing Kenney’s prior patent,
“voluntarily restricted himself to a ‘specific structure’ operative when the sleeve was ‘simply’ inserted in the cap, without suggesting any rotary movement whatever, but, on the contrary, by his reference to Kenney * * * clearly implying that no such rotary movement was necessary in the adjustment of his socket.”
We hold it clear, and counsel agree, that, though different in detail, the Ostrander socket operates according to the same law of being as does that of Freeman, or any other socket whose cap first slides like Weber and then has added to it a bayonet twist or any reasonable equivalent thereof. It is clear that, if Freeman does not infringe, Ostrander cannot.
We have not overlooked the language of the Supreme Court in speaking of a “supposed conflict” between the two circuits, and in saying that the constructions held in this court to infringe “were so essentially different from that of” Freeman that “discussion of them was quite unnecessary.” How this could have been said of the “Connecticut” device we do not understand, though it is certain that the Ostrander device was not before the Supreme Court. But the application of plaintiff’s patents to it is absolutely controlled by the decision of the highest court, with the result that defendant’s sockets do not infringe.
Decree reversed, and cause remanded, with directions to dismiss the bill for noninfringement, with costs in both courts.
