Durie Tangri Wins Federal Circuit Argument

November 17, 2015

Durie Tangri secured a big win for client Ariosa, with the Federal Circuit vacating and remanding the Patent Trial and Appeal Board (PTAB) decision upholding competitor Verinata’s patent involving non-invasive cell-free fetal DNA testing for Down Syndrome, which has also been asserted against Ariosa in litigation.  This the first time the Federal Circuit has overturned a PTAB decision upholding the validity of a patent and only the second time the Federal Circuit has reversed a PTAB decision in favor of a patentee.  Mark Lemley, Daralyn Durie, and Alexandra Moss led the appeal.  View the full order here.
