American physicists Arthur Schawlow and Charles Hard Townes patented the laser. However, another American, Gordon Gould, invented the same device independently of them. This led to the twenty-eight-year lawsuit. The term "laser" is an acronym for "light amplification by stimulated emission of radiation."
