On June 13, 2013, the U.S. Supreme Court issued its long-awaited decision in the “ACLU/Myriad” gene patenting case (formally, Association For Molecular Pathology. et al. v. Myriad Genetics, Inc., et al., Supreme Court No. 12-398). In a unanimous opinion authored by Justice Thomas, the Court held that “a naturally occurring DNA segment is a product of nature and not patent eligible merely because it has been isolated, but that cDNA is patent eligible because it is not naturally occurring.”
