The latest company targeted by Myriad Genetics for offering a genetic diagnostic test encompassing the human BRCA 1 and BRCA 2 genes is Invitae Corp. located in San Francisco.  Myriad sued Invitae on Monday in the District of Utah, Central Divisions (Case No. 2:13-CV-01049-EJF; complaint), and the next day Invitae filed its own lawsuit, seeking a declaratory judgment, in the Northern District of California (Case No. 3-13-cv-05495; complaint).  Myriad's complaint is similar to Myriad's complaints against other defendants, and includes infringement allegations relating to its mutY homolog (MUTYH) test for hereditary colon cancer in addition to its BRCA gene patent-based claims.  Once again, Myriad is joined by the University of Utah Research Foundation, the Trustees of the University of Pennsylvania, HSC Research and Development Limited Partnership, and Endorecherche Inc.

This Complaint alleges that:

On September 10, 2013, Defendant announced that it would "add BRCA1 and BRCA2 testing in future product releases."  At the 2013 Annual Meeting of the Association for Molecular Pathology held in Phoenix, Arizona from November 12-16, 2013, Defendant announced that it would begin offering its BRCA1 and BRCA2 analysis as part of its cancer-testing menu during the week of November 18, 2013.  Defendant added BRCA1 and BRCA2 gene testing into the offered panel testing services promoted on its website on November 19, 2013.  On information and belief, Defendant offers full gene sequencing and deletion/duplication analyses for the BRCA 1, BRCA 2, and MUTYH genes as part of multiple hereditary cancer panels that test cancer susceptibility using next-generation sequencing technology.

Myriad alleges infringement by Invitae's "making, manufacturing, promoting, marketing, advertising, distributing, offering for sale and selling and/or causing to be offered or sold certain "Hereditary Breast and Ovarian Cancer Syndrome," "High-Risk Hereditary Breast Cancers," "Women's Hereditary Cancers," and "Hereditary Cancer Syndromes" panel products."  The specific claims Myriad alleges are infringed include the following:  claim 6 of U.S. Patent No. 5,747,282; claims 7, 8, 12, 23, and 26 of U.S. Patent No. 5,753,441; claim 4 of U.S. Patent No. 6,033,857; claims 32 and 33 of U.S. Patent No. 6,051,379; claim 5 of U.S. Patent No. 6,951,721; claims 3, 4, 5, 6, 7, 8, 11, 14, 17, 18, 19 of U.S. Patent No. 7,250,497; claims 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18 of U.S. Patent No. 7,470,510; claims 10, 11, 15, 16, 17 and 19 of U.S. Patent No. 7,622,258; claims 2, 8 and 16 of U.S. Patent No. 7,838,237; claims 2, 3, 5, 9, 10 and 12 of U.S. Patent No. 7,670,776; and claims 2 and 7 of U.S. Patent No. 7,563,571.

This complaint is unlike several of Myriad's earlier complaints, insofar as Myriad is not asserting certain patents or claims that it has asserted in past complaints.  These non-asserted patents and claims include:

It is unclear from the complaint whether Myriad has not asserted these claims because Invitae's genetic diagnostic methods are substantially different from the other Defendants sued in other lawsuits, or if Myriad is changing its litigation strategies at least with regard to whether it can assert claims to oligonucleotide primers and probes.

Myriad and its co-plaintiffs demand a jury trial, and request judgment of patent infringement, a preliminary and permanent 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.

Invitae's lawsuit seeks a declaratory judgment that its genetic diagnostic tests do not infringe any of Myriad's asserted patents and (or) that these patents are invalid.  In its General Allegations, Invitae asserts that it is a CLIA-certified lab "that offers customizable, clinically-relevant next-generation sequencing-based genetic testing services."  Among those services are "state of the art" genetic sequencing and testing methodologies that provide "a single test for numerous genes of interest at less than the cost of most single gene tests" currently available.  These tests encompass "over 200 human genes," including the human BRCA 1 and BRCA 2 as well as the MUTYH genes that are the subject of Myriad's patents.  Importantly, like Quest in its declaratory judgment action, Invitae alleges that it "performs its sequencing using a very different approach" than the ways claimed in Myriad's asserted patents.

Invitae's complaint acknowledges Myriad's complaint filed in Utah, and the company asserts that it intends to file a motion to dismiss in that action.  Invitae asserts that "Myriad's filing of the Utah Action, however, makes it inescapably clear that an actual and justiciable controversy has arisen and presently exists between the parties with respect to the validity and infringement by Invitae of the Myriad Patents," justifying Invitae's attempt to have the California court grant judgment of non-infringement and/or invalidity.  Invitae claims that it does not use BRCA gene-specific primers, and thus that it does not infringe any of Myriad's claims reciting primer-based hybridization or sequencing methods.  In addition, like other defendants, Invitae invokes the Supreme Court (and Federal Circuit) decisions in AMP v. Myriad and the Supreme Court's Mayo v. Prometheus decision for its invalidity contentions ("A vast portion of the landscape purportedly claimed by the Myriad Patents has been washed away in the wake of the Federal Circuit and Supreme Court’s decisions" in those cases, according to Invitae).

Invitae also demands a jury trial, a declaration of non-infringement and invalidity and a finding that this is an exceptional case entitling Invitae to attorneys' fees and costs.

For those keeping score, there are now five patent infringement lawsuits pending in the District of Utah, against Ambry Genetics, Gene-by-Gene, Quest, GeneDx, and Invitae, and three declaratory judgment actions by Quest, Invitae, and Counsyl, pending in various California district courts.
