This folder contains material pertaining to a Patent Office hearing involving a patent for an improved alkaline storage battery, granted to Waldemar Jungner on September 1, 1903. Edison objected to the patent and initiated proceedings against the examiners, Thomas A. Witherspoon and Albert M. Lewers, charging them with "incompetence, neglect of duty and maladministration of office." The selected items include Edison's petition; the petitioner's brief; letters from Edison to President Theodore Roosevelt; and correspondence between Frank L. Dyer and U.S. Senator John F. Dryden of New Jersey. Also included is the decision by Assistant Commissioner of Patents Edward B. Moore, which declared the Jungner patent invalid and reassigned the examiners to another division in the Patent Office while exonerating them from charges of malfeasance.
