This article reviews the Supreme Court’s decision in Mayo v. Prometheus, 566 U.S. (2012) which held that a method of diagnostic testing was not eligible for patent protection because it described nothing more than the “conventional” application of a law of nature. It also points out that the ruling will present a challenge to U.S. patent applicants who are interested in protecting methods involving applications of a law of nature, not only in the medical arts, but in other technologies as well, such as business methods and computer technologies.
