“There can be no doubt that the doctrine of comity not only, but the orderly administration of justice, recluiros that the Circuit Court should adopt and follow the decisions of the Circuit Courts of Appeals in other circuits than their own, rendered upon facts substantially identical. Any other rule would lead to confusion and Injustice. Of course in such circumstances the defendant in patent causes may introduce new evidence of anticipation and may'show that the facts on which infringement is based are essentially different from those in the adjudicated case. Such proof must carry conviction with it.”
Appellant’s brief bitterly attacks this statement, hut we understand it to be an accurate presentation of the law and find nothing in Mast, Foos & Co. v. Stover Mfg. Co.,
The record in the Owosso Case is filed as a physical exhibit, the defendant’s record alone in that case consisting of over 1,800 printed pages. We fully concur with Judge Coxe’s finding, upon an examination of that record, that the state of the art as disclosed by prior patents and publications in evidence there is substantially the same as that disclosed here. Practically the only new questions are as to the effect of three alleged prior uses not testified to in the Owosso Case and as to infringement.
This conclusion of the Circuit Court is also bitterly assailed, and we must confess that we find it difficult to understand some of the statements in appellant’s brief. It is stated that in the Owosso suit “the only defense made to the patent was an assertion of its invalid
The appellant’s brief also contains the statement: That counsel have high confidence that this court “will not even assume that the question of double patenting was considered by the court in the Owosso Case, or any attention paid thereto.” This theory of “double patenting” is based on two earlier patents to Warren, Nos. 675,430 and 695,421. Both of these patents were in the Owosso record, and defendant’s expert, referring to them, testified (at page 758) that:
“Tbe admixture of mineral aggregate specified in patent 675,430 comes absolutely within, and is covered by, the terms of claims o and 6 of the patent .in suit.”
The briefs on the Owosso appeal are not before us, but they were before'Judge Jones in Warren Bros. v. City of Montgomery,
“I find, from examination of the defendant’s briefs before the Circuit Court of Appeals in that case, that the defense of double patenting was brought to the attention of the court and relied on.”
Under these circumstances the “assumption” which we are here asked to make is certainly remarkable. In Rosenstern v. U. S.,
