Opinion

MORRIS, District Judge.

Though this suit, instituted on the 26th day of September, 1924, by De Forest Radio Telephone & Telegraph Company against Radio Corporation of America, is an infringement suit, based upon patent No. 879,532, covering radio vacuum tubes, and though the usual relief — - injunction and accounting — -is sought, yet the underlying or subordinate issues are not of the most usual character, for the defendant concedes the validity of the patent, and that it has been selling large numbers of tubes embodying'the invention'thereof, and defends upon the grounds of want of title in the plaintiff, laehes, estoppel, and noninfringement by reason of licenses.

The differences between- the parties have their origin in an agreement, made March 16,1917, between the plaintiff and the Western Electric Company. By that agreement the plaintiff, conceded to have been then the owner of the pdtpnt, subjéct only to certain rights theretofore transferred to one Sidney 5. Meyers, conferred certain other rights upon the Western Company, by granting to that *151 company “a license * * * to make, use, install, operate, and lease, and to sell or otherwise dispose of to others for sale, installation, and operation, apparatus and systems embodying or made or operating in accordance with the” invention of the patent in suit. The license granted was for all transferable rights of the plaintiff of any kind or nature whatsoever in the patent in suit, except the rights therein expressly reserved to itself by the plaintiff. After setting out the rights reserved to the plaintiff, the agreement provided that the parties to the agreement- “may, respectively, institute and conduct suits against others for infringement of any of said patents within the fields in which it possesses rights, but all such suits shall he conducted at the expense of the party bringing them, which party shall be entitled to retain any judgment recovered in any such suits.” It was further provided that the Western Company, its successors and assigns, might assign in whole or in part the rights granted to it by that agreement, “or grant licenses to various persons, firms, or corporations for the several uses to which the inventions are applicable.”

The American Telephone & Telegraph Company acquired by assignment all- the rights of Meyers and of the Western Company in and to tho patent in suit. Subsequently, on July 1, 1920, the Telephone Company, as it was empowered to do, granted to the General Electric Company an “exclusive license to make, use, lease, and sell all wireless telephone apparatus for amateur purposes.” The General Electric Company, operating under this license, manufactured tubes for amateur purposes which were subsequently sold by the defendant. The plaintiff concedes that such tubes have been lawfully sold by the defendant, for the reason, as I understand plaintiff’s attitude, that any one has a right to resell that which a licensee has a right to manufacture and sell. The defendant, however, has also sold, under circumstances to be hereinafter stated, like tubes manufactured by the Westinghouse Electric & Manufacturing Company and by the Westinghouse Lamp Company, and it is the sale of these tubes that gives rise to the real problems and issues of this case.

The defense by way of justification with respect to the sale of the Westinghouse tubes is twofold: First, that the defendant was licensed to sell the tubes so made; and, second, that both the Westinghouse Companies were licensed to make and sell the tubes, and that hence the resale of the tubes by the defendant was not illegal. As the former of these contentions, first advanced at the final hearing, is, like the remaining contentions of the defendant, in bar of the suit, and as it has as well the added merit of going directly to tho actual and legal rectitude of defendant’s aqts, without calling for a determination, in the absence of the Westinghouse Companies, of the right of those companies to manufacture tubes embodying the invention of the patent in suit, it seems fitting that the issue of license or no license to the defendant should be first determined.

The proper solution of that problem requires an understanding of what a license is, and how it may be acquired, as well as a consideration of the evidence bearing upon that issue. Since there is here no contention that the defendant has greater rights than those of a- licensee, the term “license” may here be ' defined as a permission to make, use and/or sell articles embodying the invention, or a transfer which does not affect the monopoly of the patent otherwise than by estopping the licensor from exercising its prohibitory powers in derogation of the privileges conferred by him upon the licensee. Robinsqn on Patents, § 806.

A license may be express or implied. An express license may be conferred by a written instrument or by parol. Robinson on Patents, § 809. “An implied license may arise out of any circumstances which operate as an estoppel on the owner of the patent to prevent him from denying the rights claimed by the apparent licensee. * * * Any conduct by which the owner of the patent induces the person who employs the invention to place himself in a situation where he must suffer injury, unless his right to practice the invention is conceded, will be regarded as implying such a right, and as es-topping the owner of the patent from asserting his prohibitory powers in its defeat.” Robinson on Patents, § 834.

It would seem manifest that a license must be implied from like circumstances, without regard to whether the conduct leading to the employment of the invention by another is that of the owner, or of one who, through tho acts or agreements of the owner, has the exclusive right to grant licenses under the patent. Applying these principles to the ease at bar, it would seem obviously to follow that, in the light of the contract of March 16, 1917, by which the plaintiff, as owner of the patent, conferred mediately upon the American Telephone & Telegraph Company the exclusive right to grant licenses under the patent, this suit may not *152 be successfully maintained by the plaintiff, even if it has the legal title to the patent, if the American Telephone & Telegraph Company has conferred, by estoppel or otherwise, a license upon the defendant to sell tubes made by the Westinghouse Companies.

Has it done- so? Four documents, known respectively as A, B, C, and E, bear materially upon this issue. By the first (A), made on November 20, 1919, between Generé! Electric Company and the defendant, the former purported to grant to the latter “an exclusive, divisible license to use and sell * * * apparatus purchased from the General Company .or with its written consent * * * for radio purposes,” under patents, rights, or licenses then or subsequently owned by the General Electric Company. The latter company then had no rights under the patent in suit, .
