The Thomas A. Edison Papers Digital Edition

This folder contains material pertaining to the suit brought by Thomas A. Edison, Inc., against the United States Phonograph Co. of Cleveland, Ohio, in the U.S. Circuit Court for the Southern District of New York. The case was initiated in June 1911 and involved Edison's U.S. Patent 964,221 on a 200-thread record. The selected items consist of the bill of complaint, along with testimony by Walter H. Miller and George B. Redfearn regarding early technical and commercial experimentation with 200-thread records. Miller's and Redfearn's testimonies were entered into evidence in two companion suits against the United States Phonograph Co., which involved Edison's reissued patent on a button-ball stylus (U.S. Patent Reissue 11,857) and Peter Weber's reissued patent (U.S. Patent Reissue 13,120) on a four-minute stylus. Among the documents not selected is the application file for Edison's U.S. Patent 964,221. Related material can be found in "Phonograph - Correspondence - General."
