Ariosa Diagnostics v. Verinata Health, Inc., No. 15-1215 (Fed. Cir. 2015)
Annotate this CaseVerinata and Ariosa compete in the field of noninvasive prenatal diagnostics, including testing for fetal chromosomal abnormalities. Verinata owns the 430 patent, which describes methods of noninvasive prenatal testing for the presence of fetal chromosomal abnormalities, particularly “aneuploidy,” i.e., the presence of an abnormal number of copies of a chromosome. Ariosa petitioned the Patent Trial and Appeal Board for inter partes review and challenged the claims for obviousness under 35 U.S.C. 103. The Board concluded that Ariosa had not met its burden of proving that claims 1–18 and 19–30 would have been obvious.The Federal Circuit vacated and remanded because the Board’s language suggests it did not sufficiently consider a 2008 patent that discloses a method of determining fetal aneuploidy by isolating fetal cells, not cell-free DNA.
