OPINION BY MR. JUSTICE JONES

In this case the plaintiffs sought an accounting in equity by the defendant company for royalties allegedly due under a written agreement licensing to the defendant the manufacturing use of certain patents on demountable rim wheels for automotively propelled vehicles.

Plaintiff Vanderveer was the inventor and patentee. The other plaintiff, Florence K. Walker, obtained her interest in the contract by assignment from Vanderveer of a share therein.

In its answer to the bill of complaint, the defendant averred that the licensing contract had been terminated on a specified date; that all royalties due the plaintiffs under the contract had been paid; and that, since a time antedating the termination of the licensing agreement, the defendant had made no use of the Vanderveer patents.

While a question as to the validity of a patent raises a matter cognizable in a Federal court, the materiality and relevancy of the scope of the patent here involved lie in its being an operative factor in determining the liability, if any, of the defendant company in the premises. Broadly speaking, a licensee of a patent may not deny its validity.

Barber Asphalt Co., 292 Fed. 119, 120. Several exceptions to the general rule have since been noted. But, with that, we need not now be concerned. The validity of the patent in the instant case is not questioned. But, its scope and whether its teaching was practiced in the manufacture of the defendant's product were questions which it was necessary for the court below to pass upon, no adjudication of the patent's breadth and intendment having yet been made by a Federal court. It came to light incidentally during the oral argument of this appeal that an infringement suit between the same parties with respect to the patent here involved is now pending in the United States District Court for the Western District of Pennsylvania but that the
