The U.S. Court of Appeals for the Federal Circuit (CAFC) has reversed a district court decision finding certain claims of two patents covering prenatal DNA testing patent ineligible.

The patents at issue in the case acknowledge but are not related to the patented invention held invalid in Ariosa Diagnostics, Inc. v. Sequenom, Inc., 788 F.3d 1371, 1373 (Fed. Cir. 2015). The opinion was authored by Judge Lourie, with Judge Reyna dissenting.
