Property Rights and Personal Rights: Property rights are also distinguished from personal rights. Practically all contemporary societies acknowledge this basic ontological and ethical distinction. In the past, groups lacking political power have often been disqualified from the benefits of property. In an extreme form, this has meant that people have become "objects" of propertylegally "things" or chattels. (See slavery). More commonly, marginalized groups have been denied legal rights to own property. These include Jews in England and married women in Western societies until the late 19th century. The dividing line between personal rights and property rights is not always easy to draw. For instance, is one's reputation property that 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 patentpatenting of biotechnological processes and products based on human genetic material may be characterised as creating property in human life. A particularly difficult question is whether people have rights to intellectual property developed by others from their body parts. In the pioneering case on this issue, the Supreme Court of California held in Moore v. Regents of the University of California (1990) that individuals do not have such a property right
