[[U.S. Supreme Court]] decisions in ''[[Bilski v. Kappos]]'' (2010) and ''[[Alice Corp. v. CLS Bank]]'' (2014) made it more difficult to patent computer-related inventions by expanding the exclusion from eligibility of "abstract ideas," while ''Mayo Collaborative Services v. Prometheus'' (2012) and ''Association for Molecular Pathology v. Myriad Genetics'' (2013), denied patents to life sciences under the Court's expanded view of "laws of nature."  Only one additional Supreme Court decision has ever addressed patent eligibility: ''Diamond v. Diehr'', 450 U.S. 175 (1981).
