THE EVENING STAR, WASHINGTON, MADIO PATET U FACESIFFCULTES “Feed-Back” Circuit Fight Again May Be Thrown Into Courts. BY MARTIN CODEL. Decision was not long in coming in the famous De Forest radio patent suit. In settling the issue of Dr. Lee De For- est within a space of less than two weeks after hearing the case, the Su- preme Court of the United States has ended an 11-year fight and has opened the way to disposal of one of the most complicated situations in the history of patent law. Future legal paths, however, are be- set with difficulties which may once again throw the all-important “feed- back circuit” into the courts. It is learned from trustworthy authority here that the Government of the United States may be party to a suit to obtain title to the invention, which by assignment from De Forest is now in the hands of the American Tele- phone & Telegraph Co., with 13 years yet to run. Dr. De Forest, inventor of the three- element tube, emerges with legally sub- stantiated claims to the first discovery of the vital element in radio which ac- counts for the conversion of radio fre- quencies into audion or telephone fre- quencies and makes possible the broad- casting and reception now commonly known. The Supreme Court has de- cided that it was he, and not Arm- strong, Langmuir or Meissner, who first found the oscillating trx'opert.les of his tube and the regeneration and am- plification that are the basic essentials of radio communication. Decision Worth Million. Although future royalties accrue to the American Telephone & Telegraph Co., the inventor himself can return to the radio manufacturing field, in which he has had some unfortunate experiences. He retained rights to uti- lize the invention himself, and it is practically certain that he will re-enter the manufacture of receiving sets, just as he recently came back in the tul market. His statement that the de- cision was worth a milllon dollars to him is explained by this factor, rather ELECTRICAL HEADQUARTERS 14th & C Sts. N.W. - Arwarer Kent be | asset—though thml because of any prospect of royal- tles. The Armstrong patent is now invalid and a score or more of radio manufac- turers who are using this circuit under icenses from Westinghouse, to whom Maj. Armstrong’s patent was assigned, find themselves infringers and subject to the American Telephone & Tele- graph Co. for future licenses. Some radio manufacturers, like Westinghouse itself,. the General Electric Co. and the Radio Corporation of America, are for- tified with licenses previously obtained from the American Telephone & Tele- graph Co,, but their position now fis that they do not have exclusive rights under the feedback patent. Reached at his home in Scarsdale, N. Y., by long-distance telephone, Sam- uel E. Darby, jr., of counsel for De Forest, declared that it is De Forest's contention that no one has the right to grant licenses under this patent ex- cept the American Telephone & Tele- graph Co. This is one of the great radio patents that will not be thrown into the great cross-licensing pool, com- monly called the “radlo trust,” for sublicensing to the smaller manufac- turers at the will of the dominating concerns in the radio industry. Injunction Is to Be Asked. Mr, Darby declared that he did not think that the American Telephone & Telegraph Co. would pursue any policy of declining to license the smaller manufacturers, nor does he expect, he said, any difficulty between the Ameri- can Telephone & Telegraph Co. and De Forest over their assignment agree- ment. Mr, Darby said his next step now will be to apply to the Court of Appeals for the New York Southern District to correct its decision for Arm- strong and to issue an injunction against Westinghouse to prevent its prosscution of any sults under the Armstrong patents. The New York court records will be cleared to conform to those of the Court of Appeals at Philadelphia and the Court of Appeals of the District of Columbia, which held for De Forest in diametrically opposite findings. These latter judgments were the ones upheld by the Supreme Court in its “decision without opinion” this week. Here in Washington, it was learned that the Government is considering entering suit to claim the great De Forest patent, in its own right. alleged that in 1917, at about the time that the United States entered the war, the Government purchased all the assets of .the Federal Radio & Tele- graph Co., with whom De Forest had been a research engineer at Palo Alto, Calif. The sum paid for the company was $1,750,000, and its most valuable not discovered until later—was the De Forest invention.
