On August 16, 2012, just four weeks after it heard oral arguments, the Federal Circuit issued its second decision in Association for Molecular Pathology v. Myriad Genetics, Inc. (the ACLU ”gene patenting”/BRCAI case), which was on remand in view of the Supreme Court’s March 20, 2012 decision in Mayo v. Prometheus. The same three-judge panel heard the case on remand, and the judges reached essentially the same results on the interpretation of 35 USC § 101 as set forth in their July 29, 2011 decision. Thus, once again, Judge Lourie wrote the opinion for the court, Judge Moore concurred in the result, and Judge Bryson concurred in part and dissented in part.

All judges agree that at least one plaintiff has standing, that the diagnostic method claims based on “comparing” or “analyzing” DNA sequences are not patent-eligible, and that the drug screening method claim is patent-eligible. The court again held that all of the “isolated DNA” claims are patent-eligible, including those encompassing genomic DNA. Judge Bryson once again dissented with regard to the genomic DNA claims, but agreed with the majority that the cDNA claims satisfy 35 USC § 101.

While it is not surprising that the Federal Circuit reached the same conclusion in this decision, many will be relieved that they maintained the status quo as we move one step closer to final resolution of the issues by the Supreme Court.
