CAMPBELL-SMITH, Chief Judge

        Defendant United States moves to stay this litigation pending inter partes review
initiated by a third-party. Def.’s Mot., May 29, 2014, ECF No. 95; see Def.’s Reply, Jun.
26, 2014, ECF No. 98. Plaintiff opposes the request. Pl.’s Opp’n, Jun. 16, 2014, ECF
No. 97. The court DENIES the motion without prejudice to re-filing, upon a decision by
the United States Patent and Trademark Office (PTO) on the petition to institute inter
partes review. 1

       In September 2012, inter partes review (IPR) replaced the old inter partes
reexamination process as a new means to challenge the validity of patent claims before
the United States Patent and Trademark Office (PTO) Patent and Trial Appeal Board
(PTAB). See Leahy-Smith America Invents Act (AIA), Pub. L. No. 112-29, § 6, 125
Stat. 284, 299–305 (2011), 35 U.S.C. §§ 311–319 (2012); see also TAS Energy, Inc. v.

I.     Statement of Facts

        In August 2010, plaintiff CANVS Corporation (CANVS) filed suit seeking
reasonable and entire compensation under 28 U.S.C. § 1498(a) for defendant’s alleged
infringement of plaintiff’s U.S. Patent No. 6,911,652 filed June 28, 2005 (the patent),
disclosing a low light imaging system useful for military applications. Compl., ECF No.
1. Defendant has denied infringement and pled invalidity based on prior art and
obviousness. See Ans., Dec. 13, 2010, ECF No. 8, at ¶¶ 31–34. The parties exchanged
initial disclosures, including (according to plaintiff) thirteen boxes of original documents
from plaintiff and over 179,000 documents from defendant. See Pl.’s Opp’n 3. The
parties also exchanged disclosures of asserted claims and prior art, claim charts, proposed
claim construction statements, and expert reports in support of claim construction. See
id.; Scheduling Order, Mar. 25, 2011, ECF No. 12, amended by Order, Oct. 14, 2011,
ECF No. 18.

       Throughout 2011 and 2012, discovery and claim construction slowed to a halt in
the wake of multiple discovery disputes. These disputes culminated in numerous
published and unpublished orders and opinions concerning discovery and the scope of
claims and defenses. 2 The court then entered partial summary judgment for defendant,
invalidating claims 1–3 and claims 6–7 of the seven-claim patent as anticipated by U.S.
Patent No. 5,035,472 (the Hansen patent). CANVS v. United States, 

, 67–
73 (2013) (claims 1–3 & 6), recons. granted in part, 

, 302–03 (2014)
(claim 7).

       On June 2, 2014, the court entered a scheduling order setting deadlines for further
proceedings concerning the validity and infringement of the surviving patent claims 4 and
5. ECF No. 96. The court also denied defendant’s request to expand its prior art
disclosure, and denied plaintiff’s request to expand its claim chart, because deadlines for
both disclosures had expired two years earlier. 

Over the last several months, the
parties have restarted production of responsive documents and have been working toward

inter partes review).

discovery); Order, Apr. 9, 2012, ECF No. 21 (granting second motion to compel
discovery); Order, Dec. 16, 2013, ECF No. 82 (denying motion to amend claim chart to
add new accused devices).

filing revised claim construction positions to address a narrow construction issue still at
play in patent claims 4 and 5. See 

The pre-trial conference is set for
November 13, 2015 and trial for December 2015. 

        In addition to instituting this action, CANVS has sued various third parties in
Florida federal court, alleging that they also infringed the patent through their supply of
accused devices to the U.S. military. See RCFC 40.2 Notice of Directly Related Cases,
Apr. 21, 2014, ECF No. 90 (identifying directly related cases). Four months ago, one of
the third-parties—specifically, FLIR Systems, Inc. (FLIR)—filed a petition with the PTO
requesting inter partes review (IPR) of the patentability of all seven asserted patent
claims, including those claims previously invalidated by this court. Def.’s Mot. Ex. B,
ECF No. 95-2 (FLIR’s IPR Petition filed May 16, 2014) (arguing the patent is invalid as
obvious over the Hansen patent in combination with three other prior art references); see
Def.’s Mot. 4–5 (discussing petition). CANVS filed its preliminary response on August
25, 2014. 3 See Patent Owner’s Prelim. Resp., FLIR Sys., Inc. v. CANVS Corp., No.
IPR2014-00773 (PTAB), corrected by Patent Owner’s Corr. Prelim. Resp., FLIR Sys.,
Inc. v. CANVS Corp., No. IPR2014-00773 (PTAB Sept. 6, 2014) (technical corrections),
available at www.uspto.gov/ip/boards/bpai/prps.jsp (follow Patent Review Processing
System hyperlink; then search IPR case number or patent number for filing docket). The
PTO must decide within three months (by late November 2014) whether it will “institute”
or deny review. 35 U.S.C. § 314(b) (2012). Review is appropriate only if the PTO
determines there is “a reasonable likelihood that [FLIR] would prevail with respect to at
least [one] of the claims challenged in the petition.” 

If review is instituted,
the PTO’s Patent Trial and Appeal Board (PTAB) “conduct[s]” the review, 

and has one year to issue its findings, subject to a six-month extension for “good cause,”

Therefore, either the PTO will deny review by late November, 2014, or
it will grant review and issue a final decision on patentability by late November 2015 or,
with an extension, by late May 2016. A party dissatisfied with the PTAB’s final
determination on patentability may appeal to the Federal Circuit. 

141(c).

        Defendant seeks to stay this litigation pending resolution of the inter partes review
petition and, presumably, any subsequent appeals. In brief, defendant argues a stay is
warranted because, defendant assumes, the PTAB will invalidate the patent and render
moot this litigation through a less costly and efficient proceeding. See Def.’s Mot. 6–11.
Plaintiff responds that the stay request is inappropriate and a mere delay tactic because,
plaintiff assumes, the PTAB is unlikely to invalidate either claim 4 or 5, which are the
sole claims still at issue in this litigation. See Pl.’s Opp’n 1, 5–10. The court declines to

speculate. Rather, as set forth below, the court considers whether a stay is appropriate
pending the range of possible outcomes of a parallel PTAB proceeding.

       Of note, as of the date of this opinion, all three of the parallel Florida infringement
actions have denied similar requests to stay pending resolution of FLIR’s inter partes
review petition, including the action in which FLIR is a party. 4 See Order at 4, CANVS
Corp. v. FLIR Sys., Inc., No. 2:14-cv-00180-SPC-CM (M.D. Fla. Jun. 10, 2014), ECF
No. 21 (denying stay without prejudice to refile motion if the PTO institutes inter partes
review review); Order at 2, CANVS Corp. v. Nivisys, LLC, No. 2:14-cv-00099-SPC-
DNF (M.D. Fla. Jul. 31, 2014), ECF No. 25 (same); Order at 1, CANVS Corp. v. Exelis,
Inc., No. 2:14-cv-00100-SPC-CM (M.D. Fla. Jul. 2, 2014), ECF No. 21 (“Upon review
and in its discretion, the Court does not find[] a stay is appropriate at this stage of the
proceedings.”).

II.    Standard of Review

         The court has inherent power to stay proceedings pending inter partes review. 5
See Ethicon, Inc. v. Quigg, 

, 1426–27 (Fed. Cir. 1988); Core Laboratories
LP v. Spectrum Tracer Servs., LLC, 532 F. App’x 904, 911 (Fed. Cir. 2013). However, a
stay is not automatic. See Viskase Corp. v. Am. Nat’l Can Co., 

, 1328
(Fed. Cir. 2001); accord Comcast Cable Commc’ns Corp., LLC v. Finisar Corp., No. C-
06-04206-WHA, 

, at *1 (N.D. Cal. Apr. 5, 2007) (explaining that stays
are not automatic because “federal infringement actions would be dogged by fits and
starts . . . [and] should not be hijacked in this manner”); Soverain Software LLC v.
Amazon.com, Inc., 

, 662 (E.D. Tex. 2005) (observing that a per se
rule “would invite parties to unilaterally derail timely patent case resolution”). Rather,
the decision to grant a stay falls within the court’s sound discretion. See VirtualAgility,
Inc. v. Salesforce.com, Inc., 

, 1310 (Fed. Cir. 2014) (addressing stays in
the context of PTO review of a covered business method patent); Procter & Gamble Co.
v. Kraft Foods Global, Inc., 

, 848–49 (Fed. Cir. 2008) (discussing discretion
to issue stays in the context of inter partes reexamination); Cherokee Nation of Okla., v.
United States, 

, 1416 (Fed. Cir. 1997) (discussing stays generally).

4
       The court may take judicial notice of decisions of other courts. See Advanced
Software Design Corp. v. Fed. Res. Bank of St. Louis, 

, 1379 n.3 (Fed. Cir.
2009).
5
       Although inter partes review is a new means to challenge patent validity, the same
general principles that governed stays pending the old inter partes reexamination process
should apply with equal force to stays pending the new inter partes review. E.g.,
Ultratec, Inc. v. Sorenson Commc’ns, Inc., No. 13-CV-346-BBC, 

, at
*2 (W.D. Wisc. Nov. 14, 2013) (C.D. Cal. 2013). Accordingly, the court relies
throughout this opinion on authority to issue stays in both the old and new contexts.


                                              4
Moreover, because litigation and reexamination “are concepts not in conflict,” the two
actions may continue along parallel tracks. 

(internal quotation
omitted); Straight Path IP Group, Inc. v. Vonage Holdings Corp., No. 14-502 (JLL)
(JAD), 

, at *2 (D.N.J. Aug. 28, 2014) (“[N]o conflict [exists] . . . ,
despite the fact that the two forums may come to differing conclusions on the same
patent; the PTO and the district courts apply different standards and come to different
legal conclusions.”).

        The moving party bears the burden of showing that a stay is appropriate, Netlist,
Inc. v. Smart Storage Sys., Inc., No. 13-cv-589-YGR, 

, at *1 (N.D.
Cal. Aug. 21, 2014), and such showing must be based on more than the mere fact that a
petition for inter partes review was filed, Automatic Mfg. Sys., Inc. v. Primera Tech., Inc.
(Automatic Mfg. I), No. 6:12-cv-1727-Orl-37DAB, 

, at *3 (M.D. Fla.
May 13, 2013); see Lifewatch Servs., Inc. v. Medicomp, Inc., No. 6:09-cv-1909-Orl-
31DAB, 

, at *1 (M.D. Fla. Mar. 16, 2010) (“[A] stay should ordinarily
be denied unless there is a substantial question of patentability.”).

       Courts considering the issue have weighed three factors: (1) the impact of inter
partes review, to include whether a stay would simplify the issues in question and
streamline the trial; (2) how far the litigation has progressed, taking into account whether
discovery is complete and a trial date has been set; and (3) whether a stay would unduly
prejudice or present a clear tactical disadvantage to the non-moving party. See, e.g.,
Straight Path, 

, at *2; Automatic Mfg. Sys., Inc. v. Primera Tech., Inc.
(Automatic Mfg. II), No. 6:12-cv-1727-Orl-37DAB, 

, at *2 (M.D. Fla.
Nov. 21, 2013); e-Watch, Inc. v. Lorex Canada, Inc., No. H-12-3314, 

,
at *1 (S.D. Tex. Sept. 26, 2013); Universal Elecs., Inc. v. Universal Remote Control, Inc.,

, 1030–31 (C.D. Cal. 2013); cf. 

(adding a fourth factor when considering a stay pending review of a covered business
method patent). The inquiry is not limited to the aforementioned factors however; it
ultimately is governed by giving consideration to the “totality of the circumstances.”
E.g., Universal 

(internal quotation omitted); Endotach
LLC v. Cook Med., Inc., No. 1:13-cv-01135-LJM-DKL, 

, at *3, *5
(S.D. Ind. Mar. 5, 2014).

III.   Discussion

       A.     The Impact of Inter Partes Review on the Litigation

        Under the first factor, the Federal Circuit has recognized that a stay is favored if
PTO review would simplify or assist the court’s patent validity determination or
eliminate its need to try infringement claims. See Slip Track Sys., Inc. v. Metal Lite,
Inc., 

, 1341 (Fed. Cir. 1998). District courts also have favored a stay to
avoid inconsistent results, to benefit from PTAB guidance, to further judicial economy,
and to conserve party and judicial resources. Destination Maternity Corp. v. Target


                                              5
Corp., No. 12-5680, --- F. Supp.2d ---, 

, at *2 (E.D. Pa. Mar. 24,
2014); Evolutionary Intelligence, LLC v. Apple, Inc., No. C 13-04201 WHA, 

, at *2 (N.D. Cal. Jan. 9, 2014); Broad. Innov., LLC v. Charter Commc’ns Inc., No.
03-cv-2223, 

, at *8 (D. Colo. Jul. 11, 2006) (noting a stay “would
further the interests of judicial economy and the conservation of the parties’ resources”).

        Defendant is correct that all seven patent claims are at issue in both proceedings.
Def.’s Mot. 6–8. Defendant is also correct that if the PTO institutes review, it would
reach a decision on patentability in November 2015 (absent an extension) prior to the
commencement of this court’s December 2015 trial. 6 See Def.’s Reply 6. Accordingly,
if the PTAB were to cancel or narrow all claims by November, it would simplify the
December trial by narrowing the issues or rendering trial moot because inter partes
review findings are binding on this court. See Fresenius USA, Inc. v. Baxter Int’l, Inc.,

, 1340 (Fed. Cir. 2013) (“[W]hen a claim is cancelled, the patentee loses
any cause of action based on that claim, and any pending litigation in which the claims
are asserted becomes moot.”), reh’g en banc denied, 

(2013), cert. denied,

(2014).

        Conversely, even if patent claims 4 and 5 were to survive PTAB review, the
PTAB’s final decision sustaining these claims would contain analysis that would be
helpful to the court. See Def.’s Mot. 2, 8 (arguing the PTAB’s unique expertise and
ability, in this case, to consider obviousness combinations not presently before the court).
A richer prosecution history aids the court in its work. See Gould v. Control Laser Corp.,

, 1342 (Fed. Cir. 1983); accord Intellectual Ventures II LLC v. Huntington
Bancshares Inc., No. 2:13-CV-00785, 

, at *2 (S.D. Ohio Jun. 10,
2014); TAS Energy, Inc. v. San Diego Gas & Elec. Co., No. 12-cv-2777-GPC(BGS),

, at *4 (S.D. Cal. Feb. 26, 2014) (explaining “the PTO’s decision ‘is
strong evidence that the court must consider in assessing whether the party asserting
invalidity has met its burden of clear and convincing evidence’”) (quoting Evolutionary

6
        Defendant is adamant that the remaining patent claims 4 and 5 are “highly
unlikely . . . [to] survive the [inter partes review] process” given the narrow issue of
independent brightness adjustment and the fact that this court has already invalidated
claims 1–3 and 6–7. See Def.’s Mot., May 29, 2014, ECF No. 95, at 6, 8; Def.’s Reply,
Jun. 26, 2014, ECF No. 97, at 1, 5 n.4. In contrast, plaintiff contends that claims 4 and 5
are “highly likely” to survive inter partes review because they already have survived
summary judgment. See Pl.’s Opp’n 2. The court will not speculate on the likely
outcome of a third-party inter partes review petition or the extent to which the unique
procedural posture of this case might have some effect. See Rensselaer Polytech. Instit.
v. Apple, Inc., No. 1:13-CV-0633 (DEP), 

, at *8 (N.D.N.Y. Jan. 15,
2014) (declining to predict the likelihood of PTO review, except to acknowledge
statistics that suggest PTO review may be more likely than not).


                                             6
Intelligence, LLC v. Facebook, Inc., Nos. C-13-4202-SI, C-13-4204-SI, 

, at *2 (N.D. Cal. Jan. 23, 2014)); In re Cygnus Telcomm. Tech., LLC, Patent
Litig., 

, 1024 (N.D. Cal. 2005).

       The court is cognizant of Congress’s intention to offer, through inter partes
review, a more streamlined, efficient and less costly alternative to litigation. See
Universal 

(discussing same); Def.’s Mot. 8; Def.’s Reply
1–3 (arguing same). The court also is aware that if it stays this action, the parties will
realize some of these benefits through more limited discovery, albeit to a far lesser degree
than Congress intended in light of the status of this litigation and, in particular, the
extensive discovery that has already occurred. See Def.’s Reply 3 n.3.

        Other factors, however, weigh against the possibility that inter partes review
would simplify this litigation, and these factors merit consideration. Among these factors
is the decision pending before the PTO regarding whether it will initiate or reject review,
which creates uncertainty about whether a stay would simplify issues in this case. See
Ultratec, Inc. v. Sorenson Commc’ns, Inc., No. 13-CV-346-bbc, 

, at *3
(W.D. Wisc. Nov. 14, 2013). An examination of the case law reveals that some courts
are willing to rule on a motion for stay before the PTO decides whether to initiate review.
E.g., Endotach, 

, at *5 (denying stay before PTO determined whether it
would grant inter partes review of the petition); Intertainer, Inc. v. Hulu, LLC, No. 13-cv-
5499-CJC (RNBx), 

, at *1 (C.D. Cal. Jan. 24, 2014) (granting stay
before PTO initiated post-grant review of a covered business method patent). Yet, other
courts—seemingly the majority—deny the motion as premature while permitting
defendants to refile for stay if the PTO later accepts review. E.g., Straight Path, 

, at *3; Netlist, Inc. v. Smart Storage Sys., Inc., No. 13-cv-5889-YGR, 

, at *2–3 (N.D. Cal. Aug. 21, 2014) (factor weighs “neutral” until the PTO
decides whether to proceed with review); Rensselaer Polytech. Inst. v. Apple Inc., No.
1:13-CV-0633 (DEP), 

, at *2, *5–9 (N.D.N.Y. Jan. 15, 2014); Procter &
Gamble Co. v. Team Techs., Inc., No. 1:12-cv-552, 

, at *3–4, *4 n.1
(S.D. Ohio Sept. 10, 2013) (citing additional authorities for the principle that a stay is
premature before the PTO grants review); see also Checkfree Corp. v. Metavante Corp.,
No. 12-cv-15, 

, at *1 (M.D. Fla. Jan. 17, 2014) (granting stay pending
PTO review of a covered business method patent only after deferring on motion pending
PTAB’s determination that review was appropriate); Automatic Mfg. I, 

, at *3 (denying stay as premature before PTAB accepts review), revisited by
Automatic Mfg. II, 

, at *4 (granting stay after PTAB accepted review).
Of note, the parallel Florida court actions brought by CANVS against third parties have
taken this same approach, denying as premature the requests to stay the district court
proceedings pending FLIR’s petition for inter partes review (including the action in
which FLIR is a party). 

Section I (citing decisions).




                                             7
        The Federal Circuit “express[es] no opinion on which is the better practice.” See

–16 (discussing the timing of stay motions in the context
of a stay request pending the post-grant review of a covered business method patent).
But, the Federal Circuit observes that, “[w]hile a motion to stay could be granted even
before the PTAB rules on [whether to review a patent], no doubt the case for a stay is
stronger after . . . review has been instituted.” 

cf. Procter & Gamble Co. v.
Kraft Foods Global, 

(explaining that a stay pending the old inter
partes reexamination process “should ordinarily not be granted unless there is a
substantial patentability issue raised [in the petition]”).

       Anticipating the lack of uniformity among the various court decisions, defendant
argues that the early filing of the motion to stay in this case should not be a matter of
concern to the court because defendant expresses confidence that PTO review will be
forthcoming. Def.’s Mot. 7 (arguing PTAB review is a “virtual certainty”). Defendant
contends that (i) the PTAB has a high statistical rate of granting petitions; and (ii) the
PTAB is likely to reconsider patentability in light of this court’s partial summary
judgment opinion invalidating five of the seven claims. 

6–8; Def.’s Reply 8–9.
In contrast, plaintiff responds that inter partes review is “highly likely to be denied, and if
granted is unlikely to result in cancellation of [c]laim 4 or [c]laim 5, which [already
survived summary judgment].” See Pl.’s Opp’n 2. The court again declines to accept the
likelihood of either party’s speculation.

        The court will not base its stay decision on speculation as to the likelihood that the
PTO will accept review or ultimately cancel one or more claims. Such “review is not
automatic and requires [the PTO’s independent determination] of a substantial question
of patentability” presented, in this case, through a third-party’s inter partes review
petition. See Malibu Boats, LLC v. Nautique Boat Co., Inc., No. 3:13-CV-656-TAV-
HBG, 

, at *4 (E.D. Tenn. Aug. 6, 2014) (internal quotation omitted).
Even if the court’s invalidation of patent claims 1–3 and 6–7 were to inspire PTO review
of those claims, there can be no guarantee the PTO also would accept review of claims 4–
5, let alone cancel them.

        In any event, even if the PTO were to review all of the claims presented in this
case, there are no estoppel benefits to be obtained that would ensure that a stay achieves
the intended efficiencies in this circumstance. A petitioner seeking inter partes review is
subject to a statutory estoppel requirement that precludes the petitioner from asserting
invalidity in a subsequent lawsuit “on any ground that the petitioner raised or reasonably
could have raised during that inter partes review.” 35 U.S.C. § 315(e)(2). “This critical
limitation results in a more streamlined litigation and reduces the likelihood of
inconsistent judgments.” PersonalWeb Tech., LLC v. Google, Inc., No. 5:13-cv-1317-
EJD, 

, at *5 (N.D. Cal. Aug. 20, 2014); accord TAS Energy, 

, at *4 (“Even if all the asserted claims survive inter partes review, the case could
be simplified because [d]efendant would be bound by the estoppel provisions . . . and


                                               8
could not raise any arguments it raised or reasonably could have raised at the PTO in its
petition.”).

          The petitioner who has sought the inter partes review concerning the patent-in-suit
is neither defendant nor CANVS, but rather the third-party FLIR. Thus, the statutory
estoppel limitation does not apply in this case because defendant as movant for the stay is
not the petitioner; nor has defendant agreed to be bound to the same scope of statutory
estoppel applicable to FLIR. With no estoppel requirement here, defendant would be at
liberty to bring to the court the same arguments that were, or could have been, raised by
FLIR with the PTAB. This ability to assert the same positions in a different forum
defeats one of the intended benefits of inter partes review, should any claims survive inter
partes review. See PersonalWeb Tech., 

, at *5 (explaining these
concerns are “serious” as “the expected efficiencies [of stay] would be eviscerated
. . . .”); Evolutionary Intelligence, 

, at *2 (agreeing with plaintiff that a
defendant’s “failure to agree to be bound weakens [the simplification] factor”);
Interwoven, Inc. v. Vertical Computer Sys., Inc., No. C 10-4645 RS, 

, at
*3 (N.D. Cal. Mar. 8, 2012) (denying stay where estoppel did not apply). But see
Intellectual Ventures, 

, at *2, *4 (finding the lack of estoppel not
dispositive because estoppel would be irrelevant if the inter partes review invalidates the
asserted claims, rendering moot the litigation).

        To support a stay request, some non-petitioner defendants have agreed to be
subject to the same estoppel effects as the inter partes review petitioners. E.g.,
Intellectual Ventures II LLC v. Commerce Bancshares, Inc., No. 2:13-CV-04160-NKL,

, at *3 (W.D. Mo. Jun. 4, 2014); 

n.2
(explaining that non-petitioner defendants in the case before the court will agree to be
estopped to the same extent as the petitioner seeking review of a covered business
method patent); cf. e-Watch Inc. v. Avigilon Corp., No. H-13-0347, 

,
at *3 (S.D. Tex. Dec. 17, 2013) (ruling on the proper scope of estoppel voluntarily
assumed). Defendant in this case has not offered to do so.

        In other cases, courts have conditioned stays on the defendant’s agreement to be
bound as if it had filed the petition. E.g., PersonalWeb Tech., 

, at *5;
Evolutionary Intelligence, LLC v. Millenial Media, Inc., No. 5:13-CV-04206-EJD, 

, at *4 (N.D. Cal. Jun. 11, 2014); cf. Evolutionary Intelligence, LLC v.
Sprint Nextel Corp., No. C-13-4513-RMW, 

, at *6 (N.D. Cal. Feb. 28,
2014) (conditioning stay on the agreement to a limited estoppel, precluding only the
assertion of any invalidity contention that was actually raised and finally adjudicated in
the inter partes review proceedings, rather than the full scope of any argument raised or
that could have been raised). Here, the court declines to impose on defendant such a
condition.




                                             9
      Although the court recognizes the potential for some simplification of the sole
remaining claims 4 and 5 of the seven-claim patent, the prematurity of defendant’s
motion and the lack of estoppel benefits to be gained weigh against the grant of a stay.

       B.     Progress in this Case

        This second factor calls for an examination of the progress already made in
litigation and often has included a specific inquiry into whether discovery is complete
and a trial date has been set. 7 E.g., Evolutionary Intelligence, 

, at *2.
When parties are mid-discovery—as they are in this case—some courts have determined
that this factor weighs in favor of a stay if there remains substantial work to do or
significant milestones to meet, such as the completion of claim construction, expert
discovery, or summary judgment. See Convergence Techs. (USA), LLC v. Microloops
Corp., No. 5:10-CV-02051 EJD, 

, at *4 (N.D. Cal. Apr. 12, 2012)
(favoring a stay where, despite completion of construction briefing and age of the case, it
had not reached a “point of no return”); TAS Energy, 

, at *3
(concluding a stay “would not be improper” where there remains “expert discovery,
summary judgment motions and trial”); Affinity Labs, 

, at *2 (favoring
a stay where discovery, depositions, expert reports, and summary judgment remained).

       But, if protracted and expansive discovery has already occurred, or the court has
expended significant resources, then courts have found that this factor weighs against a
stay. E.g., Endotach, 

, at *4 (finding party’s substantial investment in
preparing for summary judgment cut against a stay); Universal 

–32 (“The Court’s expenditure of resources is an important factor in evaluating the
stage of the proceedings.”); SenoRx, Inc. v. Hologic, Inc., No. 12-173-LPS-CJB, 

, at *5–6 (D. Del. Jan. 11, 2013) (explaining that once “the Court and the
parties have already expended significant resources on the litigation[,] . . . the principle of
maximizing the use of judicial and litigant resources is best served by seeing the case
through to its conclusion”); Xerox Corp. v. 3Com Corp., 

, 407
(W.D.N.Y. 1999) (finding stay inappropriate where parties already engaged in substantial
discovery and dispositive motions).

         Discovery in this case is not yet complete and trial is scheduled to be held in
December 2015, shortly after defendant filed its request for stay. See Def.’s Mot. 8;
Scheduling Order at 3, Jun. 2, 2014, ECF No. 96. Defendant contends that discovery is
still in its “early stages,” pointing out that claim construction is pending and the parties

7
       Generally, the court should measure litigation progress as of the filing of the
motion rather than later, when it rules on the motion. VirtualAgility Inc. v.
Salesforce.com, Inc., 

, 1317 (Fed. Cir. 2014). But see 

n.6
(“[T]here was no error in also taking into account the stage of litigation as of the date that
[PTO] review was granted.”).


                                              10
have yet to conduct expert discovery on infringement and damages discovery. Def.’s
Mot. 8–9 (capitalization omitted).

        Both the parties and the court have expended substantial resources to advance this
case. Progress in this litigation has not been insignificant. The parties have responded to
written discovery regarding infringement and invalidity, have exchanged thousands of
pages of documents, inspected prior art, and have taken depositions. In addition, the
court has resolved numerous discovery disputes in multiple orders. 8 

note 2
(listing orders). The court also entered partial summary judgment invalidating patent
claims 1–3 and 6, and (on cross-motions from the parties) reconsidered that ruling to
invalidate claim 7 as well. The parties exchanged claim construction positions years ago
and, following summary judgment, have narrowed their claim construction dispute to a
sole remaining phrase or two—even as plaintiff insists that claim construction is not
necessary. See Status Report, Apr. 28, 2014, ECF No. 91, at 3–6.

      The parties and court have expended considerable effort in this case and have
made substantial progress. This work has resulted in a narrower and more refined dispute
between the parties. The advanced procedural posture of this case militates against a
stay.

       C.     Prejudice and Tactical Disadvantage

        The last factor requires that the court evaluate “whether a stay would ‘unduly
prejudice or present a clear tactical disadvantage to the non-moving party.’” E.g., TAS
Energy, 

, at *5 (quoting Medicis Pharm. Corp. v. Upsher-Smith Labs.,
Inc., 

, 993–94 (D. Az. 2007)). Informing the court’s determination
are: “‘the timing of the request for reexamination, the timing of the request for stay,
[and] the status of the reexamination proceedings.’” Bonutti Skeletal Innovs., LLC v.
Zimmer Holdings, Inc., Nos. 12-cv-1107 (GMS), -1109 (GMS), -1110 (GMS), 

, at *2 (D. Del. Apr. 7, 2014) (quoting Boston Scientific Corp. v. Cordis Corp.,

, 789 (D. Del. 2011)); TruePosition, Inc. v. Polaris Wireless, Inc., No.
12-646-RGT/MPT, 

, *6 (D. Del. 2013). Courts also consider “the
relationship of the parties,” including whether the plaintiff is a non-practicing entity or
whether the parties are direct competitors. Bonutti Skeletal, 

, at *4;
True Position, 

, at *5. In general, the delay inherent in PTO review is
insufficient to constitute undue prejudice unless it results in a sufficient tactical
disadvantage to the non-moving party. See Bonutti Skeletal, 

, at *4
(delay insufficient) (citing cases); TAS Energy, 

, at *5 (same); In re


8
        Defendant argues that plaintiff is responsible for the delayed discovery. Def.’s
Mot. 9. But, responsibility is not relevant to the consideration of this factor. Rather, this
factor is concerned with what progress has been made and what remains to be done.


                                             11


–24 (delay insufficient unless it creates tactical
disadvantage).

        Weighing in favor of stay here is the fact that the parties are not direct
competitors. Any harm that might result from a temporary stay of this litigation could be
addressed through a final damages award. E.g., TAS Energy, 

, at *5.
But cf. Air Vent, Inc. v. Owens Corning Corp., No. 2:10-cv-1699, 

, at
*3 (W.D. Pa. May 8, 2012) (“Courts are more likely to find undue prejudice when the
parties are direct competitors.”); Universal 

(“[I]nfringement among competitors can cause harm in the marketplace that is not
compensable by readily calculable money damages.”) (internal quotation omitted);
Ultratec, 

, at *4 (W.D. Wisc. Nov. 14, 2013) (explaining that plaintiff
is likely to lose significant market share during a stay if the parties are direct competitors
in a small market).

       Also weighing in favor of a stay is defendant’s prompt request for a stay within
two weeks of FLIR having filed its petition for inter partes review. Contrary to plaintiff’s
assertions that defendant is attempting to use the request for review to delay these
proceedings, there is no evidence—only plaintiff’s argument—that defendant’s motive is
dilatory. See Pl.’s Opp’n 8, 10.

        A critical countervailing consideration, however, is that a grant of stay at this time
is likely to put plaintiff at a tactical disadvantage. Defendant had an opportunity to seek
inter partes review earlier in this case, and it chose not to do so. See 35 U.S.C. § 311(c).
Instead, defendant elected to pursue litigation and aggressively challenge plaintiff at
every turn. In furtherance of the litigation, both the parties and court devoted significant
time and resources. Defendant now seeks to avail itself of the benefits of a stay pending
inter partes review, without any of the attendant risks for such a petitioner. 9 Thus,
defendant can sit idly by while a third party defends its interests, and plaintiff continues
to expend resources. See PersonalWeb Tech., 

, at *5 (characterizing
the “[d]efendants request [for] discretionary relief from this court based not on their own
efforts but on the diligence work of third parties” as an “easily-exploited opportunity”);
Endotach, 

, at *4 (“[B]y failing to file its own [inter partes review], but
now trying to ride the coat tails of a third party, [defendant] has unfairly disadvantaged
[plaintiff].”). Moreover, defendant may use the inter partes review to preview the
viability of the positions it shares with FLIR and of plaintiff’s responses.

        The court discerns a measure of undue prejudice and a tactical disadvantage to
plaintiff under this factor that counsels against a stay.

Section III.A (discussing statutory estoppel).


                                              12
IV.    Conclusion

        The Court finds that a stay pending inter partes review initiated by a third party is
inappropriate at this time based on a review of the relevant factors and considering the
totality of the circumstances. Accordingly, defendant’s motion for a stay is DENIED
without prejudice.

        If the PTAB institutes review, defendant may refile its motion to stay within
twenty (20) days of the PTAB’s decision, taking care to address the impact, if any, of:
(i) the PTAB’s decision to accept review; (ii) defendant’s status as a third party to the
inter partes review not subject to statutory estoppel in this court; and (iii) any changed
factual circumstances.

       IT IS SO ORDERED.
