Fonar Corp. v. General Electric Co.
"Fonar" was a dispute between medical device manufacturer Fonar Corporation and General Electric over Fonar's patent on MRI technology. Fonar's founder, Raymond Damadian, was issued U.S. Patent 3,789,832 (priority date 1972-03-17) for an "apparatus and method for detecting cancer in tissue" using the magnetic resonance of atoms. Damadian's patent was the first patent on an MRI machine issued in the United States. Also at issue was a later patent, U.S. Patent 4,871,966 issued in 1989, covering a method for obtaining MRI images of multiple planes at different orientations in a single scan. GE is a major manufacturer of MRI scanners, and Fonar sued GE for infringing these patents by producing its scanners as well as inducing others to infringe.
William P. Murphy Jr.
Murphy practiced medicine for a short time as an intern at St. Francis Hospital in Honolulu and later, at Peter Bent Brigham Hospital in Boston (now Brigham & Women’s Hospital). While at St. Francis, he developed his first medical invention—a projector for presenting full-size x-rays to large audiences. Murphy and the other interns were regularly required to show x-rays of their patients to doctors. To simplify this task, Murphy created a projector that was capable of showing a full-size x-ray on the screen and was easy to use—quite an accomplishment at that time, since a prompt means for converting x-rays to transparencies did not exist.
