Abstract

In March 2010, a United States (U.S.) District Court held that isolated human genes are “products of nature”, and methods of analysis and comparison “abstract mental processes”, for which a U.S. patent cannot validly be granted. Its decision undermined U.S. patent granting practices, and widens the gap between U.S. and European law on what constitutes inherently patentable subject matter (“inventions”), as well as a proportionate patent grant.
