This is a patent infringement suit in which infringement is alleged of letters patent No. 1,507,016 and No. 1,507,017, granted on September 2, 1924, to Lee De Forest. The former relates to an audion oscillator; the latter to a feed-back circuit. In Radio Corporation v. Radio Laboratories, 293 U.S. 1, 55 S.Ct. 928, 79 L.Ed. 163, the patents were held valid.
