ORDER DENYING MOTION TO

(Re: Docket No. 134) 

Part of the quid pro quo of any stay pending inter partes review before the Patent Office is 

the promise of simplification. Not a guarantee, to be sure, but at least a promise that in exchange 

for freezing a case on the court’s docket, significant issues may go away for good. Where the IPR 

will address some, but not all, claims asserted in the district court, relative to the quo the value of 

the quid shrinks considerably.

United States District Court

For the Northern District of California

Defendants HTC America, Inc., HTC Corporation, AT&T Mobility LLC, Cellco 

Partnership, Sprint Spectrum L.P., Kyocera Corporation, Boost Mobile, T-Mobile USA, Inc. and 

ZTE (USA), Inc. seek a stay pending resolution of an inter partes review now before the Patent 

Trial and Appeal Board.

1

 Plaintiff Adaptix Inc. opposes. Because the court is not convinced that a 

stay would enhance efficiency in a case where only certain claims are in review proceedings, the 

motion is DENIED.

I.

A stay is an “intrusion into the ordinary processes of administration and judicial review, and 

accordingly is not a matter of right, even if irreparable injury might otherwise result to the 

appellant.”2 “There is no per se rule that patent cases should be stayed pending reexamination, 

because such a rule ‘would invite parties to unilaterally derail’ litigation.”3 “A court is under no 

obligation to delay its own proceedings by yielding to ongoing PTO patent reexaminations, 

regardless of their relevancy to infringement claims which the court must analyze.”4 

Adaptix filed these relates suits for infringement of United States Patent Nos. 7,454,212 and 

6,947,748. On November 26, 2014, Kyocera filed petitions for IPR as to both patents.5 

Defendants moved for a stay in mid-March, and the parties appeared for oral argument in late 

 

1

 Defendants Verizon Wireless and Dell Inc. filed notices of joinder to Defendants’ motion. See

Case No. 5:14-cv-01259: Docket Nos. 170, 175. Dell Inc. has since been dismissed from this case. 

See Case No. 5:14-cv-01259: Docket No. 182. The motion is DENIED as to Defendant Verizon 

Wireless, as well.

2 Nken v. Holder, 556 U.S. 418, 427 (2009). 

3 ESCO Corp. v. Berkeley Force & Tool, Inc., Case No. 09-cv-01635, 2009 WL 3078463, at *2 

(N.D. Cal. Sept. 28, 2009). 

4 Id.; see also Viskase Corp. v. Am. Nat’l Can Co., 261 F.3d 1316, 1328 (Fed. Cir. 2001) (“The 

court is not required to stay judicial resolution in view of the reexaminations.”). While these cases 

address the more ancient reexamination proceeding, the principle applies with equal force to 

review proceedings like the one at issue here.

 Adaptix currently accuses Defendants in the Kyocera cases of infringing claims 1, 8, 11, 12, 15, 

18, 23, 25-27 and 29 of the ’212 patent and claims 8, 9, 21 and 22 of the ’748 patent.

United States District Court

For the Northern District of California

April.6 On June 10, 2015, the PTAB instituted IPR on claims 8, 9, 21 and 22 of the ’7487 but 

denied institution of IPR on claims 1, 8-13, 15, 18, 19 and 23-29 of the ’212 patent.8 

II. 

This court has jurisdiction under 28 U.S.C. §§ 1331 and 1338. The parties further 

consented to the jurisdiction of the undersigned magistrate judge under 28 U.S.C. § 636(c) and 

Fed. R. Civ. P. 72(a). 

III. 

“Courts have inherent power to manage their dockets and stay proceedings, including the 

authority to order a stay pending conclusion of PTO reexamination.”9 “In determining whether to 

grant a stay pending PTO review, courts consider: (1) whether discovery is complete and whether a 

trial date has been set; (2) whether a stay will simplify the issues in question and trial of the case; 

and (3) whether a stay would unduly prejudice or present a clear tactical disadvantage to the nonmoving party.”10 Applying these standards to the situation at hand, the court is not persuaded that 

a stay makes sense.

 

6 See Case No. 5:14-cv-01259: Docket Nos. 79, 97. 

7 See Kyocera Corp., v. Adaptix, Inc., IPR2015-00319, Paper 10 at 2 (PTAB June 10, 2015). 

8 See Kyocera Corp., v. Adaptix, Inc., IPR2015-00318, Paper 10 at 2 (PTAB June 10, 2015). The 

court acknowledges that IPR proceedings on these patents have been instituted in other cases. For 

example, Sony Mobile Communications (USA) Inc. is a party to two of the cases related to this set 

of actions. See Case Nos. 5:14-cv-1385-PSG and 5:15-cv-00972. Notably, the PTAB instituted 

IPR as to all claims at issue in the litigation, see Sony Mobile Comms. (USA) Inc., v. Adaptix, Inc., 

IPR2014-01524, Paper 16 at 2 (PTAB Apr. 7, 2015); see Sony Mobile Comms. (USA) Inc., v. 

Adaptix, Inc., IPR2014-01525, Paper 15 at 2 (PTAB Apr. 8, 2015), but Sony does not seek a stay 

nor does it join this motion. In addition, none of the defendants here are estopped under 

35 U.S.C. § 315 from asserting the same prior art should the claims survive.

United States District Court

For the Northern District of California

First, discovery in this set of cases is advanced. Courts in this district have routinely 

refused to grant a stay pending IPR where a case is past the early stages of proceedings.11 While 

the range of what qualifies as “early stage” is relative, there is a general consensus that where “the 

parties have fully briefed the issue of claim construction, attended a Markman hearing, and 

received a claim construction order,” discovery is well underway such to counsel against granting a 

stay.12 And there is no colorable claim that these cases are any different.13 Here, a trial date is set 

for August 2016, the court has construed claims not once, not twice, but three times, the parties 

have exchanged voluminous document productions—in the Wave 1 cases at the very least—and 

fact discovery is set to close in just over a month.14 With the trial date just under a year away, 

these cases have already reached an advanced stage, and this court has put significant work into 

getting these cases this far. This all weighs against granting a stay.

Second, it seems unlikely that the PTAB’s review will simplify the issues in these cases

enough to justify granting a stay. Sure, “waiting for the outcome of the reexamination could 

eliminate the need for trial if the claims are cancelled or, if the claims survive, facilitate trial by 

providing the court with expert opinion of the PTO and clarifying the scope of the claims.”15 But 

 

11 See, e.g., Telemac Corp., 450 F. Supp. 2d at 1111; Verinata Health, Inc., 2014 WL 121640, at 

*2. 

12 Interwoven, Inc. v. Vertical Computer Sys., Case No. 10-cv-04645, 2012 WL 761692, at *4 

(N.D. Cal. Mar. 8, 2012); Verinata Health, Inc., 2014 WL 121640, at *2 (holding where a trial date 

is set, claim construction order issued and parties exchanged initial disclosures, infringement and 

invalidity contentions and some document productions, a case is not in an early stage of 

proceedings).

13 As of the time the PTAB instituted IPR in June 2015, discovery was substantially complete. 

Cf. VirtualAgility Inc. v. Salesforce.com, Inc. 759 F.3d 1307, 1317 n.6 (Fed. Cir. 2014) (“While 

district courts should generally consider ‘whether discovery is complete and whether a trial date 

has been set’ as of the date of the stay motion, there was no error in also taking into account the 

stage of litigation as of the date that [] review was granted.”).

14 See Case No. 5:14-cv-02359: Docket No. 43. The parties have agreed that discovery from 

certain related cases may be shared across the cases for the sake of efficiency. As a result, because 

the Wave 1 cases proceeded to summary judgment, a significant amount of discovery has already 

taken place, greatly minimizing any efficiency that a stay might provide. See id.

United States District Court

For the Northern District of California

here, the PTAB only instituted IPR in Kyocera’s petition as to the ’748 patent, which only 

encompasses four claims. By contrast, the PTAB denied Kyocera’s petition as to all 17 claims 

challenged in the ’212 patent. With fewer than 25 percent of the claims at issue subject to inter 

partes review,16 the overall effect of any PTAB decision—whether it cancels all or some claims, 

amends all or some claims, or allows all or some claims to survive—will be minimal relative to the

number of claims not under review.17 This also weighs against granting a stay. 18

Third, other than delayed gratification, Adaptix cannot show that “a stay would [cause 

undue] prejudice or present a clear tactical disadvantage.”19 “Mere delay in the litigation does not 

establish undue prejudice.”20 Rather, courts decline to find undue prejudice where the parties are 

not direct competitors and where any resulting prejudice can be addressed through a final damages 

award.

21 Here, while it is undisputed that the parties are not in direct competition, Adaptix argues 

 

cancelled, the patentee loses any cause of action based on that claim, and any pending litigation in 

which the claims are asserted becomes moot.”)).

16 In VirtualAgility Inc. v. Salesforce.com, Inc., the Federal Circuit, in reversing the district court’s 

denial of a stay, emphasized the “significan[ce] that the PTAB granted [] review on all asserted 

claims of the sole asserted patent.” 759 F.3d at 1314 (emphasis in original). By contrast, here, the 

PTAB only granted IPR as to a sliver of the claims at issue, leaving an entire patent untouched. 

17 See Universal Elecs., Inc. v. Universal Remote Control, Inc., 943 F. Supp. 2d 1028, 1032 (C.D. 

Cal. 2013) (holding that simplification or clarification by PTAB review particularly likely “when a 

party has obtained PTO review of each of the asserted claims in the patents-in-suit); see also 

Yodlee, Inc. v. Ablaise Ltd., Case Nos. 06-cv-07222, 06-cv-02451, 07-cv-01995, 2009 WL 112857, 

at *5 (N.D. Cal. Jan. 16, 2009) (“To truly simplify the issues . . . the outcome of the reexamination 

must ‘finally resolve all issues in the litigation.’”). 

18 Even if all claims were to survive, Defendants cannot argue simplification based on estoppel; 

because Kyocera is the only defendant that sought inter partes review, the estoppel provisions do 

not extend to any other defendants joining in this motion for stay. See 35 U.S.C. § 315(e)(2) (“The 

petitioner in an inter partes review of a claim in a patent . . . may not assert . . . that the claim is 

invalid on any ground that the petitioner raised or reasonably could have raised during that inter 

parties review.”).
