Case No. 15-cv-02216-SI 

ORDER CONSOLIDATING CASES 

AND DISMISSING WITHOUT 

PREJUDICE MOTIONS TO DISMISS 

Re: Dkt. Nos. 27, 28, 29, 34, 38

Now before the Court are motions by defendants Ariosa Diagnostics, Inc. and Roche

Molecular Systems, Inc. to dismiss Illumina’s first amended complaint (“FAC”) for failure to state 

a claim. The motions are currently set for argument on August 13, 2015. Docket Nos. 27, 28. 

Pursuant to Civil Local Rule 7-1(b), the Court finds this matter appropriate for resolution without 

oral argument and hereby VACATES the hearing. For the reasons stated below, the Court 

CONSOLIDATES this action with Case No. 12-cv-5501, and STAYS the action in accordance 

with its prior order. See C. 12-cv-5501, Docket Nos. 229, 230. Ariosa’s and Roche’s motions are 

DISMISSED without prejudice to refiling upon the lifting of the stay.

BACKGROUND

This is a patent infringement action. Plaintiffs Illumina Inc., Verinata Health, Inc. and the 

Board of Trustees of the Leland Stanford Junior University (collectively “Illumina”) accuse 

Ariosa’s HarmonyTM Prenatal Test of infringing U.S. Patent No. 8,296,076 (“the ’076 patent”), 

U.S. Patent No. 8,318,430 (“the ’430 patent”), and U.S. Patent No. 7,955,794 (the ’794 Patent). 

Defendant Ariosa has filed a counterclaim for breach of contract.

In May 2013, Ariosa filed petitions for inter partes review, requesting that the Patent Trial

and Appeal Board (“PTAB”) review claims 1-30 of the ’430 patent and claims 1-13 of the ’076 

patent. On October 25, 2013, the PTAB instituted inter partes review of claims 1-30 of the ’430 

Patent on obviousness grounds. On November 20, 2013, PTAB instituted inter partes review of 

claims 1-13 of the ’076 Patent on anticipation and obviousness grounds. On October 23, 2014, the 

PTAB issued two orders holding that Ariosa had failed to show that claims 1-30 of the ’430 Patent

are unpatentable. See Ariosa Diagnostics, Petitioner, IPR2013-00276, 2014 WL 5454541(Oct. 23, 

2014); Ariosa Diagnostics, Petitioner, IPR2013-00277, 2014 WL 5454542 (Oct. 23, 2014). On 

November 19, 2014, the PTAB issued an order finding that the challenged claims of the ’076 

Patent are unpatentable. See Ariosa Diagnostics, Petitioner, IPR2013-00308, 2014 WL 6617697 

(Nov. 19, 2014). These PTAB rulings have all been appealed to the Federal Circuit. On January 8, 

2015, PTAB instituted inter partes review of claims 1-22 of the ’794 Patent. See Ariosa 

Diagnostics, Inc., Petitioner, IPR2014-01093, 2015 WL 153677 (Jan. 8, 2015).

On August 7, 2014, this Court held that Ariosa was entitled to pursue its counterclaims for 

breach of contract and the covenant of good faith and fair dealing in a judicial forum, 

notwithstanding an arbitration clause in the underlying contract between the parties. C. 14-cv1921, Docket No. 40. These counterclaims are of central importance to Ariosa’s defense, because 

they relate to its assertion that Illumina granted it an express or implied license to practice the ’794 

Patent. Id. at 5. On September 8, 2014, Illumina appealed this Court’s ruling to the Federal 

Circuit. C. 14-cv-1921, Docket No. 56.

On February 2, 2015, this Court granted Ariosa’s third motion to stay pending the final 

exhaustion of the inter partes review proceedings to which the ’794 Patent is subject, the Federal 

Circuit appeals from inter partes review to which the ’430 and ’076 Patents are subject, and the 

appeal from this Court’s order finding that it has subject matter jurisdiction to hear Ariosa’s 

breach counterclaims. Docket No. 229.

The present action was filed by Illumina on May 18, 2015. Docket No. 1. Illumina filed an 

amended complaint on June 10, 2015. Docket No. 17, FAC. The FAC alleges infringement of the 

’794 patent against both Ariosa and Roche by performing a new “microarray-based version” of the

HarmonyTM Prenatal Test.

1 Now before the Court are Ariosa’s and Roche’s motions to dismiss, 

filed on July 7, 2015. Docket Nos. 27, 28.

DISCUSSION

In their motions, Ariosa and Roche argue that the FAC is legally defective for failure to 

state a claim, but also procedurally defective because it constitutes an improper collateral attack on 

the Court’s stay order in C. 12-cv-5501. Specifically, defendants contend that if Illumina wishes to 

add a new infringing product – the microarray-based Harmony Test – and a new party – Roche –

to the litigation, it must wait for the stay to be lifted and file a motion to amend its complaint. 

Defendants argue that the proper remedy is to dismiss this action in its entirety. However, in the 

event the Court declines to dismiss this case, defendants argue that it should be consolidated and 

stayed with C. 12-cv-5501.

Illumina argues that this litigation is not a collateral attack on the Court’s stay order, 

because it could not have been reasonably expected to amend its complaint in the stayed case. It 

notes that this litigation was stayed only a few days after the new microarray-based test was put 

into use, and only a few weeks after Roche’s acquisition of Ariosa became final. Accordingly, it 

had insufficient time to draft and file a motion to amend its complaint before the stay was put into 

effect. Additionally, Illumina points to a contractual obligation with a non-party to this action 

which precluded it from bringing an infringement suit against the microarray-based test before 

mid-May of 2015. Illumina urges the Court to consolidate and stay this case with the currently 

stayed litigation. 

“If actions before the court involve a common question of law or fact, the court may

consolidate the action.” Fed. R. Civ. P. 42(a)(2). District courts have “broad discretion under this

acquisition was completed in January of 2015, making Ariosa a wholly-owned subsidiary of 

Roche. FAC ¶ 6.

rule to consolidate cases pending in the same district.” Investors Research Co. v. U.S. Dist. Court 

for Cent. Dist. of California, 877 F.2d 777, 777 (9th Cir. 1989). “To determine whether to 

consolidate, a court weighs the interest of judicial convenience against the potential for delay, 

confusion and prejudice caused by consolidation.” Southwest Marine, Inc. v. Triple A Mach. Shop, 

Inc., 720 F. Supp. 805, 807 (N.D. Cal. 1989).

The parties dedicate much of their briefs and many, many words to dichotomizing what is, 

at bottom, a distinction without a difference. In practice, whether the Court adopts plaintiffs’ or 

defendants’ preferred course of action makes little difference to the outcome of this case; it will 

confer no substantive litigation advantage, nor inflict prejudice upon either party. In any event, 

the Court finds that the interests of judicial economy would be best served by consolidating and 

staying this case. Accordingly, the Court CONSOLIDATES this case with C. 12-cv-5501, and 

STAYS the case in accordance with its prior order. See C. 12-cv-5501, Docket Nos. 229, 230. All 

pending motions are DISMISSED without prejudice to refilling upon the lifting of the stay. This 

order resolves Docket Nos. 27, 28, 29, 34, 38.

IT IS SO ORDERED.
