This folder contains material pertaining to a suit brought by Edison against former employees James W. Gladstone and Eben G. Dodge, who established the Battery Supplies Co. to compete with the Edison Manufacturing Co. in the sale of primary batteries. The case, which was initiated in the U.S. Circuit Court for the District of New Jersey in July 1903, involved the alleged infringement of Edison's U.S. Patent 430,279. The selected items include the bill of complaint, answer, and affidavits; correspondence regarding the progress of litigation; and a settlement agreement signed in November 1904. Also included is an undated answer by Edison, filed in the countersuit brought against him and the Edison Manufacturing Co. by Gladstone, who claimed the right to manufacture batteries under Felix Lalande's U.S. Patent 479,887. At the end of the folder is an agreement of August 4, 1905, between Gladstone and the Edison Manufacturing Co., providing for the purchase of the Battery Supplies Co. by Edison's company.
