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.
Nobel Prize controversies
The 2003 prize was awarded to Paul Lauterbur and Sir Peter Mansfield "for their discoveries concerning magnetic resonance imaging" (MRI). Two independent alternatives have been alleged. Raymond Damadian first reported that NMR could distinguish "in vitro" between cancerous and non-cancerous tissues on the basis of different proton relaxation times. He later translated this into the first human scan. Damadian's original report prompted Lauterbur to develop NMR into the present method. Damadian took out large advertisements in an international newspapers protesting his exclusion. Some researchers felt that Damadian's work deserved at least equal credit. Separately, Herman Y. Carr both pioneered the NMR gradient technique and demonstrated rudimentary MRI imaging in the 1950s. The Nobel prize winners had almost certainly seen Carr's work, but did not cite it. Consequently, the prize committee very likely was unaware of Carr's discoveries, a situation likely abetted by Damadian's campaign. Mansfield said in his autobiography that "the person who really missed out" the prize was Erwin Hahn for his contribution to the principles of spin echoes.
