Myriad Genetics Files Suit Against Ambry Genetics for Genetic Diagnostic Testing of BRCA Genes

On July 9, 2013 Myriad Genetics sued Ambry Genetics, Corp. in the District of Utah, Central Division for patent infringement of ten patents relating to genetic diagnostic testing (Case No. 2:13-cv-00640-RJS; complaint). Ambry Genetics was one of the first companies to announce that it would provide genetic diagnostic testing for the BRCA 1 and BRCA 2 genes on the day the U.S. Supreme Court announced its decision in AMP v. Myriad Genetics on the question of "whether human genes are patentable." Joining Myriad as plaintiffs are the University of Utah Research Foundation, the Trustees of the University of Pennsylvania, HSC Research and Development Limited Partnership, and Endorecherche Inc.


The Complaint alleges that:

Defendant began offering its BRCA1 and BRCA2 analysis as part of its cancer testing menu on June 13, 2013. On information and belief, Defendant offers stand-alone tests comprising full gene sequencing and deletion/duplication analyses for the BRCA 1 and BRCA 2 genes. On information and belief, Defendant also offers full gene sequencing and deletion/duplication analyses for the BRCA 1 and BRCA 2 genes as part of multiple hereditary cancer panels that test cancer susceptibility using next-generation sequencing technology.

Defendant is infringing, contributing to the infringement of, and/or inducing others to infringe the '999 patent by making, manufacturing, promoting, marketing, advertising, distributing, offering for sale and selling and/or causing to be offered or sold certain BRCA1, BRCA2, BRCAPlus, BreastNext, OvaNext, and CancerNext products that infringe at least the following claim of [each of the patents in suit] literally and/or under the doctrine of equivalents for ten patents owned or licensed to Myriad.

These method claims differ from the claims invalidated by the District Court in the Myriad case and affirmed by the Federal Circuit, which recited as limitations merely "comparing" an individual's BRCA gene sequence with the "normal" one, and thus Myriad is less likely to be estopped from asserting these claims against Ambry.

Myriad's Relief Requested in its complaint includes judgment of patent infringement, an injunction, an accounting and damages, delivery for destruction of all "products" that infringe any of the asserted claims, a finding of willful infringement, and a request for attorneys' fees, enhanced damages and costs of suit. Myriad also demands a jury trial.

As has been discussed in earlier posts, some of these claims (e.g., directed to oligonucleotides) may be subject to invalidation on novelty grounds (see "Caught in a Time Warp: The (In)validity of BRCA1 Oligonucleotide Claims"). In addition, not all assignees are named in the complaint (most notably the U.S. Government "as represented by the Secretary of Health") and insofar as any of them are adjudged to be indispensible parties, any unwillingness to be joined might cause Myriad procedural difficulties. But it is significant that Myriad has decided to assert these patents, and its continued ability to do so illustrates one of the generally unappreciated aspects of the Myriad case. Plaintiffs in that case and their supporters, the ACLU and Public Patent Foundation, chose the claims against which to assert their challenge to the validity of Myriad's patents. Which means, of course, that they chose not to challenge the claims Myriad is now asserting, leaving the plaintiffs (including breast cancer patients) without the full and complete remedy they no doubt were promised and that the press seems to believe the Supreme Court's June 13 decision gave them (see "Reaction to Supreme Court's Decision in AMP v. Myriad" and "Does the Myriad Decision Presage a Golden Age of Patent-Free Personalized Medicine?"). Instead, plaintiffs challenged claims to isolated DNA (characterized as "genes"), even though such claims are not infringed by the practice of modern genetic diagnostic methods. The result of these strategic (and ultimately political or at least public-relations focused) decisions is that Myriad owns or has licensed patents that presumptively preclude Ambry Genetics or any other provider from offering BRCA gene-directed genetic diagnostic tests until these patents expire in the next few years. In short, the parties are in exactly the same position that existed prior to the Myriad suit. While this outcome should have been expected, it raises doubts about the consensus narrative of what "everybody knows" this case was all about.
