This folder contains material pertaining to three suits brought against the American Graphophone Co. in the U.S. Circuit Court for the Southern District of West Virginia. The first two suits were initiated by the National Phonograph Co. in June 1905; the third by the New Jersey Patent Co. in November 1906. The cases involved three patents on methods of duplicating phonograph records—Walter H. Miller's and Jonas Walter Aylsworth's U.S. Patents 683,615 and 683,676 and Maurice Joyce's U.S. Patent 831,668. The cases were consolidated by stipulation in January 1908 and dismissed with costs to the defendant in December 1910. The selected documents include correspondence by Frank L. Dyer and Herbert H. Dyke of the Legal Department and Philip Mauro and C. A. L. Massie, attorneys for the defendant, pertaining to the progress of litigation. Also included are the following items from the printed record of the consolidated case: index; complainant's brief in support of a motion to suppress the deposition of Mauro; defendant's brief in opposition to the motion; defendant's proofs; and complainant's rebuttal proofs.
