Marconi Wireless Telegraph Co. v. De Forest Wireless Telegraph Co.
U.S. Circuit Court for the District of Southern New York
1Opinion of the Court
TOWNSEND, Circuit Judge.
This suit, by bill and answer, raises the questions of the validity, and of infringement by defendant, of complainant’s reissued patent No. 11,913, granted to Guglielmo Marconi June 4, 1901, for improvements in transmitting electrical impulses and signals and in apparatus therefor. This patent is the reissue of the fundamental Marconi patent, No. 586,193, dated July 13, 1897, for transmitting electrical signals. The issues involved relate to the art of wireless telegraphy, and more especially to its latest development, sometimes termed “spark telegraphy.”
