Edison's technical work on motion pictures resulted in a major patent infringement suit filed in 1898 on Edison's U.S. Patent No. 589,168. Testimony and exhibits from this suit were often entered into evidence in subsequent cases brought by Edison and his companies on this patent and its reissue, No. 12,192.

The Complainant's Record has been selected in its entirety. It provides information concerning early work on motion pictures undertaken at the West Orange laboratory. One additional item has been selected immediately preceding the record: a summary of the testimony establishing the date of Edison's invention, which appears on pages 14-31 of the Brief for Complainant.
