Hazeltine Research, Inc. v. General Motors Corp., 72 F. Supp. 138, 74 U.S.P.Q. (BNA) 85, 1947 U.S. Dist. LEXIS 2467 (E.D. Mich. 1947).

Opinion

LEDERLE, District Judge.

1.These actions involve the validity and infringement of Claims 1, 2, 3, 5, 6 and 8 of Wheeler Patent No. 1,951,685, hereafter referred to as the ’685 patent, which issued March 20, 1934, on a “Peak Detector” for radios, and Claims 1 to 12, inclusive, of Wheeler Patent No. 2,041,273, hereafter referred to as the ’273 patent, which issued May 19, 1936 for “Amplifier Volume Control”. Both patents are based upon an application, Serial No. 203,879, filed July 7, 1927, by Harold A. Wheeler. The Complaints, alleging defendant’s infringement of these patents, were filed in January, 1941, by Hazeltine Corporation. By consent, Hazeltine Research, Inc., as-signee of Hazeltine Corporation, and present owner of the patents, was substituted as plaintiff. At the request of both parties, trial was delayed for the duration of the war. The cases were thereafter consolidated for trial, and trial was concluded April 22, 1947. The patents in suit are closely related, as is the prior art, and, therefore duplicate findings of fact and conclusions of law will be filed in each case.

2. Mr. Wheeler received his degree of Bachelor of Science in Physics from Georgetown University in 1925, and then continued his studies at John Hopkins University. He was particularly interested in radio, and had built a radio transmitter and receiver prior to 1924. During the latter part of 1925, he designed and constructed a radio receiver he considered to be superior to any such device then known. This receiver, referred to in record as the “Washington Receiver,” was demonstrated in January, 1926.

3. On July 7, 1927, Wheeler filed his application, serial number 203,879, describing all of the features of his Washington Receiver. This application was assigned to plaintiff’s predecessor corporation. Under the guidance of skillful patent counsel, on the basis of this one application and divisions and continuations thereof, plaintiff’s predecessor corporation secured the following seven patents, each containing numerous claims, all based upon the combination embodied in the Washington Receiver, viz.:

Patent No. Issue Date Title

1.879.861 Sep. 27, 1932 Volume Control

1.879.862 Sep. 27, 1932 Volume Control

1.879.863 Sep. 27, 1932 Volume Control

1,951,685
