The dividing line between personal rights and property rights is not always easy to draw. For instance, is one's reputation property which can be commercially exploited by affording property rights to it? The question of the proprietary character of personal rights is particularly relevant in the case of rights over human tissue, organs and other body parts.

There have been recent cases of women being subordinated to the fetus, through the imposition of unwanted caesarian sections. English judges have recently made the point that such women lack the right to exclusive control over their own bodies, formerly considered a fundamental common law right. In the United States, a "quasi-property" interest has been explicitly declared in the dead body. Also in the United States, it has been recognised that people have an alienable proprietary "right of publicity" over their "persona". The patenting of biotechnological processes and products based upon human genetic material may be characterised as creating property in human life.
