Edward Armstrong, distinguished radio in- | ventors, to the “feed-back™ or regen- erative cirenit in receiving sets. It was enrried ‘to the Supreme Court by the | Westinghouse Electric & Manufactur- | ing Co., purchaser of the Armstrong patent, which aske decisions in Federal | Courts awarding patent right in the| circuit to the DeForest Radio Telephone | & Telograph Co. The Westinghouse Co. contende that | |a final decision 18 imperative a8 the business of making and selling appara- |tus using the “feed-back” amounts to millions of dollars annually. The case has been in litigatiori for eight years, with both sides winning court contests, In 1920, a New York court ruled that Armstrong had ptrior rights. This deci- sion was affirmed by the Circuit Court |of Appeals, and in 1923 the assistant commissioner of patents awarded priority of invention to Armstrong. On appeal, DeForest won a reversal of the ecision by the Circuit Court of Appeals of the Diatrict of Columbia, |2 and Pennsylvania and Delaware courte subsequently held Armstrong's patent |to be in confliet with two DeForest patents. These opiniohs were afflrmed( by the Cireuit Court of Appeals for the | third efrcuit. | Arguments before the Supreme Court will be mads by a formidable array of opposing lawyets, mcluding ~Chatles | Evans Hughes, chief of counsel for the TheNational Super-Smokeless | PFre € £ Gives Supex-Service 9,640’384 FAMILIES OWN RADIO SETS lightful aroma will please you. not get a box at this low price?
