Overview
Case summary
McIntosh Battery & Optical Company appealed a decree dismissing its patent infringement suit against Charles Birtman, Jacob Nelson, and Felix Soeding. The suit alleged infringement of two patents (Nos. 275,347 and 331,754) issued to Philip Atkinson for improvements in machines generating static electricity, involving combinations of Leyden jars, supporting beds, electrical connections, switches, combs, brushes, plates, and hubs. The defendants denied invention and infringement, citing prior patents, publications, and use. At trial, the patentee testified about improvements over prior machines (Holtz, Toepler, Voss), admitting some elements were old but claiming novel applications. The Circuit Court of Appeals, after reviewing evidence including witness testimony and documentary proof, held the patents void for lack of invention, affirming the dismissal. The court found nothing in the patents constituted patentable invention.
