Harmony Brings Discord:  Federal Circuit Affirms Finding that Ariosa Diagnostics’ Harmony® Pre-Natal Test Infringes Illumina and Verinata Health Patents

(Co-authored by Kevin Mosier)


Cell-free fetal DNA technology was again the centerpiece of a dispute between plaintiffs Illumina and Verinata Health (referred together as Illumina), and defendants Ariosa Diagnostics and Roche Molecular Systems (referred together as Ariosa) in Verinata Health, Inc., et al v. Ariosa Diagnostics, Inc., et al., No. 18-2198 (Fed. Cir. Apr. 24, 2020). At issue in the case was Ariosa’s pre-natal diagnostic test marketed as Harmony®. While Section 101 eligibility was not at issue, the Federal Circuit provided important commentary related to enablement and availability of injunctive relief, affirming a jury determination of validity in view of an enablement challenge, largely based on the referenced prior art and other evidence not strictly tied to the disclosures in the patent itself. Specifically, the jury below found that Harmony® infringed U.S. Patent Nos. 7,955,794 (‘794 patent) and 8,318,430 (‘430 patent), held by Illumina and Verinata Health, respectively. The district court denied Ariosa’s motion for judgment as a matter of law (JMOL) on the validity of the ‘430 and ‘794 patents and its motion for JMOL on infringement of the ‘794 patent. The district court also denied Illumina’s post-trial motions for a permanent injunction and supplemental damages. The parties filed cross-appeals on the denials of these motions, and the Federal Circuit affirmed the district court’s denials. The court also declined to issue an injunction, citing the parties’ respective sales models as evidence that irreparable harm was lacking.
