This bound volume contains the printed record from four patent interferences and one civil court suit for the period 1880-1885. The spine is stamped "U.S. Patent Office Miscellaneous Interferences of T. A. Edison."

The volume comprises the following cases:

1. Mather v. Edison v. Scribner (1883). This 52-page pamphlet contains testimony by Edison, John F. Ott, and other associates regarding Edison's work on dynamos between 1881 and 1882.
2. Edison v. Lane v. Gray v. Rose v. Gilliland (1882). This 12-page pamphlet contains a brief filed on behalf of Edison by George W. Dyer on February 22, 1882 in two related interferences involving dynamos: Edison v. Lane v. Gray v. Rose v. Gilliland; and Edison v. Lane v. Gray v. Edison & Johnson.
3. Edison v. Nicholson (1880). This 32-page pamphlet contains testimony and other printed records, including correspondence, relating to conflicting claims over duplex telegraph patents. Among the correspondents are Henry C. Nicholson and Edison's attorney, Lemuel W. Serrell.
4. Sawyer and Man v. Edison (1881). This 198-page pamphlet contains testimony and exhibits on behalf of Edison. Most of the record from this interference (including testimony by Edison, Charles Batchelor, and Francis R. Upton) was later entered as evidence in Edison Electric Light Company v. United States Electric Lighting Company and can be found with the other records from that case. Both the interference and the court case concern Edison's early work on the incandescent lamp.
5. Edison Electric Light Company v. United States Electric Lighting Company (1885). This pamphlet contains the 8-page bill of complaint filed by the Edison Electric Light Co. in 1885. Included also are 13 pages of technical notes and drawings by Edison, which were entered as exhibits in this suit.

Also included in this volume are the records of several telephone interferences from the 1880s. These have been published in Thomas A. Edison Papers, Part I (1850-1878).
