RADIO DIGEST July 14, 1923 SURVEYS INDUSTRY'S TANGLE OF PATENTS "Cooperative Competition" Leaves Maze of Stumbling Blocks for Independent Manufacturer By John B. Brady (Editor's Xote. — Mr. Brady, a patent attorney of Radio repute, has achieved a remarkable survey of the network of patents, locking and interlocking the Radio industry in a veritable Gordian knot. HU serial treatise on the. patent situation vill occupy four parts, of which this in the first.) PART I THE RADIO industry can learn a great deal from its giant predecessor, the automobile industry, and perhaps amicably adjust the present chaotic situation arising out of the patents by a crosslicense agreement to eliminate extended litigation. The automobile industry many years ago formed a National Automobile Chamber of Commerce which the manufacturers of different makes of cars joined and interchanged their patent rights on such a basis that production might go on unhampered with patent litigation. Pressing Small Manufacturer Out The Radio patent situation for the smaller manufacturer on the outside of the big four looking in at the Radio Corporation is growing more acute each day. The Radio Corporation is bringing suits under its numerous patents and gradually pressing out the small manufacturer from his right of livelihood. Glancing over the court records of only the past twelve months shows the Radio Corporation in litigation with the Radio Audion Company under the Fleming valve patent 803,684 In which they were successful in preventing the manufacture and sale of the Myer tubes when sold as detectors, although not when sold as amplifiers and oscillators. Get Myer Injunction Upon the unsuccessful outcome of this suit the American Telephone & Telegraph Company sued the Radio Audion Company and DeForest Radio Telephone & Telegraph Calls on Radio to Add to Benefit of Churches COLUMBUS, OHIO. — Believing that the Columbus Federation of Churches can be of greater general benefit than has been before possible, Rev. Walter A. King, executive secretary, has arranged with the Erner & Hopkins Company to broadcast weekly services over Station WBAV. The services will be interdenominational and will be provided with the view of reaching many shut-ins who are often unable to attend the regular church services. Various religious leaders of Columbus will provide the programs.

Company on the DeForest amplifier patent 841,387 and grid patent 879,532 in which an injunction was obtained against the defendants. The Radio Audion Company appealed their case to a higher court. The Audion Company found the Radio Corporation circularizing the trade with unfair notices to the public having a tendency of damaging the business of the defendant, and as a result were successful in having this practise declared in contempt of court and collected damages from the corporation. B. C. A. After Small Manufacturers An apparently aggressive policy has been adopted by the Radio Corporation against the small manufacturer in bringing a number of suits, among which is that against A. H. Grebe and J. H. Bunnell & Company under the DeForest patents 841,387 and 879,532 in the Federal Court for the Southern District of New Tork to prevent Grebe as manufacturer and Bunnell as distributor (Continued on page 8) WLW Seeks Lost Dogs, Relatives and Flyers Even Fraternity Uses Airphone to Locate Missing Members CINCINNATI, O. — Broadcasting stations are called upon to aid in all kinds of searches. Requests upon station WLW, have been most varied in their demands. For example, Colonel Graham Setoh Hutchison, delegate from England to the Associated Advertising Clubs of the World convention at Atlantic City, was wanted by the Cincinnati Chamber of Commerce and, as he was flying around in an airplane from city to city on a speaking tour, it was difficult to locate him. The committee then sent a message to him via WLW and contact with him was finally made. Search for members of the Chi Sigma Chi fraternity was made by Radio and everyone belonging to this fraternity was asked from WLW to send their names to the station.
