Radio Corp. v. Andrea

June 7, 1937

RADIO CORPORATION OF AMERICA ET AL.
v.
ANDREA ET AL. (TWO CASES)



Appeal from the District Court of the United States for the Eastern District of New York.

Author: Manton

Before MANTON, SWAN, and CHASE, Circuit Judges.

MANTON, Circuit Judge.

This suit is for infringement of patents Nos. 1,507,016 and 1,507,017 issued to De Forest. The first is for an "audion oscillator" or generator of electric oscillations and the second for an "audion feed-back circuit." The circuits covered by these patents are used in radio and other arts and are recognized by defendants as inventions of great merit. See Westinghouse Electric & Mfg. Co. v. De Forest Radio Tel. & Tel. Co., 278 U.S. 562, 49 S. Ct. 34, 73 L. Ed. 507; Radio Corporation v. Radio Engineering Laboratories, Inc., 293 U.S. 1, 55 S. Ct. 928, 79 L. Ed. 163; Id., 293 U.S. 522, 55 S. Ct. 66, 79 L. Ed. 634.

This cause was considered by us on an appeal from a preliminary injunction in Radio Corporation of America et al. v. Andrea et al., 79 F.2d 626, where we held upon the record therein that the sales by the defendants were not infringements. It there appeared that the vacuum tubes were not, at the time of the sale and delivery for exportation to foreign countries, actually in the sockets provided for them in the receiver and, since the sales were for export and the tubes not placed in their sockets, it was not an infringement within the jurisdiction of the patent laws of the United States. It was held to be neither a direct nor contributory infringement. We also held that whether there had been an infringement by assembly or use and whether the defendants by virtue of the purchase of vacuum tubes acquired an implied license under the patents in suit should not be determined on the then record but should await final hearing.

Additional facts were developed at the final hearing. Defendants now admit, by stipulation, assembly and use by testing the completed superheterodyne receivers with vacuum tubes in their sockets to determine the marketability of the receiver. The defendants also admit the making of sales as described. Evidence was received directed to the issue of whether defendants by their purchase of certain vacuum tubes acquired an implied license under the patents to make, use, and sell completed superheterodyne receivers embodying the inventions in suit. The District Judge held that appellees had infringed by use in testing, and that, in view of our previous decision, the defendants' sales for export were not infringements. He also held that the defendants' claim of an implied license arising out of the purchase of such tubes after the time when a use for such tubes other than as oscillators in receiving sets became known to the art was without merit, but that prior to that time there was such an implied license, although such tubes could be used for initial installation and for replacement in receiving sets licensed to use the invention, and this even though each tube sold was accompanied by a notice restricting the use of the tube to replacements in apparatus licensed under the patents. Both plaintiffs and defendants have appealed.

Claims 19 and 25 of the respective patents sued on will be found in the margin.*fn1

The elements of the combinations covered by these claims are a vacuum tube and two coupled or associated circuits. The coupled circuits in defendants' receivers are built into the receiver and are connected to a tube socket adapted to receive the type 6 -- A -- 7 vacuum tube which cooperates with the circuits to produce oscillations.

At this trial it was admitted by the defendants that the tubes were inserted in the sockets and therefore connected with the circuits while in the defendants' plant and the entire combination was completed and used in testing the receivers. Thereafter, the tube was removed from its socket; then the receiver and the tube (or a duplicate and other tubes used in the receiver for different purposes) were packed in the receiver cabinet and thus sold. The tubes were placed in a separate carton and this, with the receiver, was placed in a larger carton. The purchaser to connect the tube needs only insert it in the socket. No adjustment is required; no screw or nut need be tightened. Where the elements of an invention are thus sold in substantially unified and combined form, infringement may not be avoided by a separation or division of parts which leaves to the purchaser a simple task of integration. Otherwise a patentee would be denied adequate protection. Cf. Eibel Process Co. v. Minnesota Paper Co., 261 U.S. 45, 63, 43 S. Ct. 322, 328, 67 L. Ed. 523.

In 79 F.2d 626, we pointed out that the defendants had sold the elements capable of forming the patented combination but had not made or sold the combination itself. For it was necessary that the elements be physically connected in an opera-able relationship. We said that the sales of disassembled elements of the patented combination was not a direct infringement although the claims be construed, as the plaintiffs urged, as not calling for a series of electrical power. There we considered the case on a bill, answering and supporting affidavits, and said: "No wrong is done the patentee until the combination is formed. His monopoly does not cover the manufacture or sale of separate elements capable of being, but never actually, associated to form the invention. Only when such association is made is there a direct infringement of his monopoly, and not even then if it is done outside the territory for which the monopoly was granted." Page 628.

As to testing, we said: "No method of testing is suggested which would not necessitate assembling the tubes and receiver and using them as the complete combination of the patents in suit. We should hesitate, therefore, to hold that the District Judge was not justified in finding that 'each set is tested by defendant before sale or packing for delivery.' But he made no express finding that such test was an infringement of the claims in suit, nor is it clearly indicated in his opinion that he would have granted a preliminary injunction if the evidence as to tests were the only proof of infringement. The injunction was granted on the basis that the defendants were manufacturing and selling a complete combination which infringed, even though the tubes were not inserted in the sockets of the receiver at the time of sale." Page 629.

On this record it appears that the receiver and tubes were assembled completely and tests of operation were made after which the tubes were taken out, packed in separate cartons but within the same larger carton as the receiver. The sales for the completed receiving sets were made within the territorial limits of the United States and shipped in export. The single package contained all the elements of the combination.

In Bullock Electric & Mfg. Co. v. Westinghouse Mfg. Co., 129 F. 105, 109 (C.C.A. 6), certiorari denied 194 U.S. 636, 24 S. Ct. 859, 48 L. Ed. 1160, the defendants sold but one element of the combination and the court held that this sale did not violate the injunction which had been issued forbidding the sale of apparatus employing the claimed invention and said: "It is elementary that neither the making, selling, nor using of one element of a combination is infringement." Further: "Unless, therefore, the making and selling of a single element of a patented device, within the limits of the United States, with the intention that it shall be sent without the United States, and there used in association with the other elements of the combination, constitutes infringement, the defendants did not disobey the order of the court." 129 F. 105, at page 110.

There is a difference between the Bullock and the instant case because here the defendants did sell all the elements of the completed patented combination, put them together, used them in testing, and then separated them merely within a ...
