Do we own our bodies? Do isolated gene sequences constitute "inventions" that warrant patent protection? What about cloned organisms, or new life-forms engineered from preexisting tissue? Do scientists have the right to claim individual patents on and make profits from the elements of life? How does the profit motive affect our attitudes toward the value of life? Will patent protection foster or hinder scientific cooperation and research into diseases? In short, who owns life?
