On March 4, 2014, the U.S. Patent and Trademark Office published a guidance memorandum entitled “Guidance For Determining Subject Matter Eligibility Of Claims Reciting Or Involving Laws of Nature, Natural Phenomena, & Natural Products.” The guidance provides a new examination procedure for evaluating subject matter eligibility of certain types of patent applications under 35 U.S.C. § 101 in view of two fairly recent Supreme Court decisions, namely, Association for Molecular Pathology v. Myriad Genetics, Inc. and Mayo Collaborative Services v. Prometheus Laboratories, Inc. The official USPTO press release can be found here.
