The first phase of the Human Genome Project came to an end by the summer of 2000. We have a fairly complete and accurate listing of all the genes in a typical human being. Apart from the tremendous impact that this knowledge will have on health care, it also represents a patent rush where both private and public institutions are trying to gain temporary control, through patents, over the use and reproduction of genetic information. This paper introduces the reader to issues involving the patent ability of genes, the tests used by patent offices to award patents. The ownership of the human genome--and the access to the tools and databases necessary to make sense out of the millions of bits of information that make up the estimated 100,000 human genes--constitutes one of the hottest debates in the public policy arena not just in the field of science but sociology, politics, law and ethics.
