The Edison National Historical Park archives has seven bound volumes and one pamphlet of Patent Office proceedings relating to conflicting claims over who invented the telephone. This volume, entitled "U.S. Patent Office, Miscellaneous Interferences of T. A. Edison" contains four documents relating to appeals taken in 1883-1884. Three of the four selected documents are briefs for Edison; the other is the decision of the Examiners-in-Chief in the appeal of Cases A, B, C, D, E, F, G, I, J, L, and No.1.
