Career
In all, Anger held 15 patents, many of them for work at the Ernest O. Lawrence Radiation Laboratory. Anger died in Berkeley, California. In 1957, he invented the scintillation camera, known also as the gamma camera or Anger camera.
Anger also developed the well counter, widely used in laboratory tests to measure radioactivity in samples.
Anger also developed a multi-plane tomographic radiation scanner using the Anger camera and a focussed radiation collimator. The first useful scintillation camera was developed by Anger at an Atomic Energy Commission-funded laboratory at the University of California at Berkeley, California.
Consequently, the patent rights on the invention were owned by the United States. Government. However, Anger"s supervisors at the lab were well-connected with the head of the Atomic Energy Commission, Glenn Seaborg, and prevailed on the Atomic Energy Commission to release the patent rights to Anger personally.
Anger retained patent counsel to file a United States. patent application on his invention, and this application eventually matured into United States. Patent 3,011,057, issued in November 1961.
While his patent was pending, Anger tried unsuccessfully to interest nuclear instrument companies in taking a license on a non-exclusive basis to produce and sell the Anger camera. He eventually granted an exclusive license on the "057 patent to Nuclear-Chicago Corporation (National Cadet Corps), in Des Plaines, Illinois. National Cadet Corps successfully developed a commercially useful version of the Anger Camera and began marketing it to nuclear medical departments of hospitals in the United States.
National Cadet Corps"s commercial sales of the Anger Camera grew substantially over the years and Anger became modestly wealthy from the royalties that he received under the exclusive license agreement.
National Cadet Corps was eventually acquired by G.D. Searle & Company, of Skokie, Illinois, and operated as a wholly owned subsidiary. Nuclear-Chicago Corporation"s exclusivity on marketing the Anger scintillation camera was eventually challenged by the introduction of a competing version of the Anger camera by Picker Corporation.
National Cadet Corps and Anger sued Picker for infringement of the "057 patent, and Picker counterclaimed for invalidity of the "057 patent. Picker also filed a proceeding in the Atomic Energy Commission, challenging the legitimacy of the Atomic Energy Commission"s release of the patent rights to Anger, and requesting a compulsory license under the "057 patent.
The Atomic Energy Commission proceeding was decided in favor of Anger and National Cadet Corps, and the patent infringement lawsuit was eventually settled by the grant of a sublicense agreement to Picker.
Other competitors later emerged and further litigation on the "057 patent was initiated. National Cadet Corps was eventually sold to Siemens Corporation and Siemens continued to develop the technology of the Anger Camera and to market the device worldwide.
