Opinion

GARRETT, Chief Judge.

This is an appeal from the decision of the Board of Interference Examiners of the United States Patent Office awarding priority of invention to the party Wright. Four counts seem to have been involved before the board, but the appeal to us was taken only as to Count 1, which reads:

1. The disazo dye of the formula:

Wright (who describes himself as a British subject in his application) is the senior party. His application was filed June 25, 1942. The application of Kvalnes, which appears to be assigned to E. I. du Pont de Nemours & Company, was filed June 17, 1943.

The board awarded Wright constructive reduction to practice as of July 22, 1941, on which date a Provisional Specification of a British application was filed in his behalf. This award is not challenged before us.

In his preliminary statement Kvalnes alleged actual reduction to practice of the count before us “during the month of June 1939.”

The board held, in effect, that the compound of the count had been produced at the time claimed for reduction to practice, but held that the tests made of the compound were not sufficient to demonstrate its utility. Therefore, it was held that appellant could not be awarded actual reduction to practice but was confined to the constructive reduction to practice incident to his filing date of June 17, 1943.

We quote the following from the board’s decision (reference to page numbers of the *194 record being omitted as indicated by asterisks) :

“Diazotization requires observance of definite conditions. Equimolecular quantities of nitrite and amine are used and the mineral acid should be in excess, at least 2 to 2^/i equivalents being present.- Diazotization is always carried out in the cold. Diazonium salts couple readily and easily to phenols and aromatic amines under the proper procedure. Both reactions are the common procedures in the azo dye laboratory and are so well standardized and understood that, taking into consideration also the observable expected phenomena accompanying the reactions, there is no question in the mind of the chemist as to the final product. This is the situation here and the evidence shows the proper procedure was followed. We believe that in the peculiar circumstances of this case, there is reasonable certainty that the compound of count 1 was produced and that analysis was not necessary to establish identification.
