ORDER GRANTING IN PART DEFENDANTS’
MOTION TO STAY PENDING INTER PARTES REVIEW
AND ADMINISTRATIVELY CLOSING CASE

THIS CAUSE comes before the Court on Defendants’ Motion to Stay Pending Inter
Partes Review and for Entry of Protective Order (“Motion”), [ECF No. 65], filed on August 2,
2022. Plaintiffs filed their Response in Opposition, [ECF No. 69], on August 16, 2022.
Defendants filed their Reply, [ECF No. 70], on August 23, 2022, followed by Plaintiffs’ Sur-
Reply, [ECF No. 71], filed on August 29, 2022.
In short, Defendants ask this Court to stay all proceedings in this action and enter a
protective order quashing all discovery until the Patent Trial and Appeal Board completes an inter
partes review of the patents at issue in this litigation. Plaintiffs oppose a stay and insist that both
sets of litigation proceed in parallel. Having considered Defendants’ Motion and Reply, Plaintiffs’
Opposition and Sur-Reply, and the record, and being otherwise fully advised, it is hereby
ORDERED AND ADJUDGED that Defendants’ Motion, [ECF No. 65], is GRANTED
IN PART for the reasons stated herein. The Court grants a stay of this case, which will expire
when the Patent Trial and Appeal Board completes an inter partes review of the Patents in Suit or
decides not to take up AMC and Lifesync’s Petitions. When the Patent Trial and Appeal Board
decides whether it will take up an inter partes review, the parties shall file a joint status report
addressing whether the inter partes review will commence. The Court will not enter a protective
order quashing discovery, as the stay of this case includes a stay of discovery. Given that the inter

partes review could impact the parties’ current arguments and legal positions, the Court finds it
advisable to deny all pending motions without prejudice, with leave to refile when the stay is lifted.
BACKGROUND
This patent infringement case involves leadwires with closed-end electrode connectors
used in cardiac monitoring equipment. The Court need not address the substantive issues in this
lawsuit to resolve the procedural question at hand. Further, the Court assumes the parties are
familiar with the procedural posture of this case and only notes that this case remains in the early
stages of litigation, and the parties have filed several motions, some of which remain pending.
Defendants seek to stay this case pending an inter partes review (“IPR”) of two petitions
(the “IPR Petitions”) that AMC and Lifesync filed with the Patent Trial and Appeal Board (the

“PTAB”). IPR “allows a [] party to ask the U.S. Patent and Trademark Office to reexamine the
claims in an already-issued patent and to cancel any claim that the agency finds to be unpatentable
in light of prior art.” Cuozzo Speed Techs., LLC v. Lee, 579 U.S. 261, 265 (2016). As a general
matter, IPR serves as “a quick, inexpensive, and reliable alternative to district court litigation to
resolve questions of patent validity.” Targus Int’l LLC v. Grp. III Int’l, Inc., No. 20-21435-CIV,
2021 WL 542675, at *1 (S.D. Fla. Jan. 8, 2021) (citing the Leahy-Smith America Invents Act and
S. Rep. No. 110-259, 20 (Jan. 24, 2008)). Congress created the IPR system in 2012 principally
“to establish a more efficient and streamlined patent system that will improve patent quality and
limit unnecessary and counterproductive litigation costs.” 77 Fed. Reg. 48,680 (August 14, 2012).
AMC and Lifesync filed two IPR Petitions with the PTAB on August 2, 2022, seeking
review of the asserted claims in the Patents in Suit. By statute, PTAB must decide whether to
institute a review within six months of the petition filing, i.e., by February 2, 2023. See id. If the
PTAB decides to take up the IPR Petitions, the PTAB must make a final determination on

invalidity within 12 months after notice of the institution of a review (extendable for good cause
by six months)—in this case, by February or August 2024. 35 U.S.C. §§ 314(b), 316(a)(11).
In the IPR proceedings, a panel of three technically trained Administrative Patent Judges
will examine the Patents in Suit for invalidity. 35 U.S.C. §§ 6(a)-(c); 35 U.S.C. § 316(c).
Defendants explain that the IPR Petitions “are based primarily upon three prior art references, two
of which were not considered by the examiner during the original prosecution of the Patents in
Suit that raise substantial new questions of patentability relative to all of the patent claims now
asserted in this lawsuit.” Motion at 1. Upon completing the review process, the PTAB will issue
a final decision concerning the patentability of the challenged patent claims. 35 U.S.C. § 318.
LEGAL STANDARD

District courts possess “inherent, discretionary authority to issue stays in many
circumstances.” Advanced Bodycare Solutions, LLC v. Thione Int’l, Inc., 524 F.3d 1235, 1241
(11th Cir. 2008). One such circumstance is when related proceedings are pending before a
different tribunal. See Ortega Trujillo v. Conover & Co. Comm., Inc., 221 F.3d 1262, 1264 (11th
Cir. 2000).
Regarding stays pending inter partes review, “the decision to stay related civil patent
infringement litigation is within the sound discretion of the district court.” Targus, 2021 WL
542675, at *1 (citing Lighting Sci. Group Corp. v. Nicor, Inc., 6:16-CV-1087-ORL-37GJK, 2017
WL 3706697, at *2 (M.D. Fla. May 9, 2017)). “This makes sense because inter partes review has
the potential to eliminate trial of invalidity issues when a claim is canceled or, otherwise facilitate
trial of remaining issues following PTO denial of reexamination or reissuance proceedings.” Id.
“Stays pending such reviews are granted routinely in order to avoid inconsistent results, obtain
guidance from the PTAB, or avoid needless waste of judicial resources.” Id.

ANALYSIS
The Court applies the three-factor test regularly used in this jurisdiction to evaluate motions
for stays pending PTAB proceedings, including IPR. See Roblor Mktg. Grp., Inc. v. GPS Indus.,
Inc., 633 F. Supp. 2d 1341, 1347 (S.D. Fla. 2008); Targus, 2021 WL 542675, at *2. The parties
dispute whether the Court must apply an additional fourth factor. Without ruling on the necessity
of this fourth factor, the Court finds that the three-factor test established in Roblor, and applied to
IPR proceedings in Targus, warrants a stay in this case—and the fourth factor upon which
Plaintiffs rely further tips the scales in favor of a stay. The Court addresses each factor in turn.
1. Undue Prejudice or Clear Tactical Disadvantage

The Court first considers “whether the stay will unduly prejudice or present a clear tactical
disadvantage to the nonmoving party.” Targus, 2021 WL 542675, at *2. The Court concludes it
will not. Plaintiffs’ undue prejudice argument comes down to timing: Plaintiffs maintain an
interest in the timely enforcement of their patent rights, Kirsch Rsch. & Dev., LLC v. Intertape
Polymer Corp., No. 8:20-CV-1982-VMC-JSS, 2021 WL 2905436, at *3 (M.D. Fla. Apr. 7, 2021),
and staying this case until the close of the IPR proceedings and possible appeal process will extend
the time needed for Plaintiffs to enforce their patent rights.
The Court recognizes that granting a stay pending IPR will lengthen the duration of this
case. However, the Court cannot find that this lengthening of time constitutes undue prejudice.
Regarding the length of the stay, Defendants do not seek, nor would this Court impose, an
indefinite stay, given the statutorily mandated 12 to 18-month deadline for the resolution of IPR
proceedings. 77 Fed. Reg. 48, 680 (August 14, 2012). And the Court will refrain from
determining, at this juncture, whether such a stay should extend throughout the appeal process.
Additionally, the stay will not entirely halt the resolution of this case, but rather allow forward

progress to be made. The IPR proceedings provide an opportunity for the accurate resolution of
at least some of the claims at issue in this case, which could benefit either party—not only
Defendants.
Plaintiffs also argue that granting a stay would provide Defendants with a clear tactical
advantage because it would “enable Defendants to get away with their strategy of not participating
in discovery and blaming Plaintiffs for it.” Response at 18. The Court does not find this to be a
“tactical advantage” that precludes the granting of a stay. As the parties are well aware, the IPR
process also allows for discovery. Automatic Mfg. Sys. v. Primera Tech., No. 6:12–cv–1727–
RBDDAB, 2013 WL 6133763, at *2 (M.D. Fla. Nov. 21, 2013). In fact, Congress designed the
IPR process “to improve upon the previous inter partes re-examination process by (1) reducing to

12 months the time the PTO spends reviewing validity, from the previous reexamination average
of 36.2 months; (2) minimizing duplicative efforts by increasing coordination between district
court litigation and inter partes review; and (3) allowing limited discovery in the review
proceedings.” Id. It is not improper, nor does it unduly prejudice Plaintiffs, for Defendants to
seek to limit their discovery obligations by entering a process created for that very purpose.
Weighing all arguments raised by the parties, the Court finds that a stay will not unduly prejudice
nor tactically disadvantage Plaintiffs.
2. Simplification of Issues

Second, the Court must consider “whether the stay will simplify issues in question and trial
of the case.” Targus, 2021 WL 542675, at *2. The Court finds that a stay will undoubtedly
simplify this case for the Court, regardless of the outcome of the PTAB’s review for two reasons.
First, the Court considers this a potentially complicated patent infringement case with
sophisticated parties. By staying this case pending the IPR proceedings, this Court will have the
opportunity to rely on a decision issued by a panel of three technically trained Administrative
Patent Judges, who will examine the Patents in Suit for invalidity. 35 U.S.C. §§ 6(a)-(c); 35 U.S.C.
§ 316(c). The full record of the IPR proceedings will be available to further assist the Court in
analyzing the remaining issues in this case and reducing the length of trial. The invaluable
expertise of the Administrative Patent Judges and resulting record will simplify this case for the
Court regardless of the outcome of the proceedings.
Second, the IPR proceedings may eliminate some of the issues to be tried before this Court,
thereby streamlining the remainder of this case and potential trial. Should the IPR invalidate any

of the claims in the Patents in Suit, fewer claims will remain for this Court to evaluate. Targus,
2021 WL 542675, at *2 (entering stay and reasoning that “[e]ven if only some of the claims are
canceled, those claims will not need to be litigated in this action, which will save the parties from
spending more time conducting discovery, researching, and briefing the issues.”); see also Trading
Techs. Int’l, Inc. v. BCG Partners, Inc., No. 10 C 715, 2015 WL 1396632, at *1, 4 (N.D. Ill. Mar.
25, 2015) (granting stay pending “CBO” review when “the PTO instituted review on only four of
the fifteen patents in issue” and “118 of the approximately 400 claims at issue”); Intell. Ventures
II LLC v. SunTrust Banks, Inc., No. 1:13-CV-02454-WSD, 2014 WL 5019911, at *2 (N.D. Ga.
Oct. 7, 2014) (“Even if the PTAB concludes that some, but not all, the Patents are invalid, the
scope of this case may be significantly narrowed.”).
Plaintiffs point out that even if IPR invalidates 23 out of the 23 claims at issue, additional
issues will remain for this Court to resolve. However, the standard is not that the IPR must

eliminate the lawsuit entirely to justify a stay; rather, only that the remaining case may be
simplified. Targus, 2021 WL 542675, at *2 (“any streamlining of the issues or invalidated issues
will save judicial resources”). Accordingly, the Court finds this factor weighs heavily in favor of
granting a stay.
3. Discovery and Trial Scheduling
The Court must consider “whether discovery is complete and whether a trial date has been
set.” Targus, 2021 WL 542675, at *2. The Court finds this factor weighs slightly in favor of
granting a stay.
This Court has set trial for July 2023, which, in some circumstances, may justify denying
a stay. E.g., Payrange, Inc. v. Kiosoft Techs., LLC, No. 20-20970-CIV, 2020 WL 9158402, at *2

(S.D. Fla. Nov. 23, 2020) (denying stay where trial “will occur well before” the PTAB could decide
an IPR). But that is not dispositive. Other courts in this district have set trial dates early in the
litigation but have nevertheless granted stays pending IPR when the other factors deem it
appropriate. E.g., Targus, 2021 WL 542675 at [ECF No. 28] (trial set for 10 months after the
decision to stay the case and before the PTAB’s final decision was due); Rothschild Storage
Retrieval Innovations, LLC v. Motorola Mobility LLC, No. CV 14-22659-CIV, 2015 WL
12715618, at *2 (S.D. Fla. May 11, 2015) (nine months). Given conflicting case law on this point,
the current trial date is a neutral factor in the analysis. The same cannot be said, however, when
one looks at the current status of discovery.
Here, the parties are in the early stages of discovery, and therefore the scheduling factor
weighs slightly in favor of granting a stay. Presently, only Plaintiffs have served discovery
requests, no depositions have been taken, and discovery remains open until March 21, 2023. While
the parties ardently disagree as to why discovery is not well-advanced, the Court concludes that

given the minimal discovery that has occurred, this factor weighs in favor of granting a stay. See
Targus, 2021 WL 542675, at *2 (granting stay pending PTAB decision where parties had
exchanged and responded to multiple sets of written discovery); Rothschild, 2015 WL 12715618,
at *2 (finding the case was “not so far along that a stay would be senseless” where “the Parties
have engaged in some written discovery, no depositions—fact or expert—have been taken, and
the claim construction briefing is in its infancy”).
4. Additional Considerations

Plaintiffs urge this Court to consider whether a stay, or the denial thereof, will reduce the
burden of litigation on the parties and the Court. Response at 19–20. Plaintiffs first argue that a
stay will not reduce, but rather increase, the burden of litigation on the parties and the Court
because Defendants fail to show any clear hardship or inequity that could outweigh the potential
of prejudice to Plaintiffs. The Court disagrees. Litigating in this Court and the PTAB in parallel—
following two sets of rules and procedures simultaneously—burdens all parties.
Plaintiffs further argue in their Sur-Reply that if 3M is not bound by IPR estoppel because
3M is not a party to the IPR Petitions, “then the burden on both the parties will be increased and
the burden on the Court will not be reduced” because “3M will have a second bite at the apple and
be able to argue any defense AM[C] and Lifesync would be estopped from arguing.” Sur-Reply
at 2. While the Court notes Plaintiffs’ concern, it cannot resolve questions of estoppel at this
juncture. Further, this concern does not impact the overall burden of litigation for all parties such
that the Court should not grant a stay.
Plaintiffs also argue that seeking a stay before the PTAB has decided whether to take up
the IPR Petitions is premature or otherwise prejudicial to Plaintiffs. When faced with this issue,

courts in this district and beyond routinely grant stays under such circumstances. Targus, 2021
WL 542675, at *1; Rothschild, 2015 WL 12715618, at *2; Andersons, Inc. v. Enviro Granulation,
LLC, No. 8:13-CV-3004-T-33MAP, 2014 WL 4059886, at *3 (M.D. Fla. Aug. 14, 2014); Roblor,
633 F. Supp. 2d at 1347 (granting motion to stay the litigation pending resolution of requests for
reexamination). Case law does not support Plaintiffs’ argument, and the Court finds that
Defendants’ Motion is not premature.
Finally, if considering this fourth factor, the Court must weigh the burden of litigation on
the Court, not just the parties. The parties have filed numerous procedural and substantive motions
with this Court at the early stages of litigation. Granting the requested stay will provide the Court
with additional resources, including the PTAB’s expertise, to rule on the parties’ motions. Putting

aside the parties’ dispute as to whether the Court must consider this factor, the Court finds that if
applicable, it weighs in favor of staying the litigation.
CONCLUSION
For the foregoing reasons, it is hereby ORDERED AND ADJUDGED as follows:
1. This case, including discovery, is STAYED pending resolution of the IPR Petitions.
2. When the PTAB announces whether it will take up the IPR Petitions, the parties shall
file a joint status report informing the Court of the PTAB’s decision.
3. The Clerk is instructed to administratively close this case while the stay is pending.
The Court will address restoring this case to the active docket once the PTAB has
reached a decision.
4. All pending motions are DENIED without prejudice.

DONE AND ORDERED in Fort Lauderdale, Florida, this 30th day of September, 2022.
