The 1980 Chakrabarty decision indicated that genetically engineered organisms were patentable. This ruling by the courts opened the door for biotechnology to become big business. Companies could now protect products based on genetically altered organisms.
The next issue that was addressed by the USPTO with respect to the patenting of life forms was the patentability of genetically manipulated animals. In 1988, a patent was allowed for the first genetically altered animal – a mouse that was very susceptible to cancer. This mouse showed promise in testing potential carcinogens.
Microorganisms, plants and animals have now all received U.S. patenting status. In Europe, the patenting of "man-made" life forms is viewed in much the same manner as in the United States.
