What Are Mayo and Myriad?

In Mayo Collaborative Services v. Prometheus Labs., Inc., 132 S. Ct. 1289 (2012), the Supreme Court articulated a two-part analytical framework for determining whether a claim is patent-eligible under 35 U.S.C. § 101.  Mayo dealt with one of three long-established judicial exceptions to patentability under 35 U.S.C. § 101: laws of nature.  In Association for Molecular Pathology v.
