Yakar Technologies, LLC v. DAS Companies, Inc.

THE UNITED STATES DISTRICT COURT
DISTRICT OF UTAH
YAKAR TECHNOLOGIES, LLC,
Plaintiff/Counterclaim Defendant,
v.
DAS COMPANIES, INC.,
Defendant/Counterclaim Plaintiff.
MEMORANDUM DECISION
AND ORDER
Case No. 2:25-cv-00508-DBB-JCB
District Judge David Barlow
Magistrate Judge Jared C. Bennett
I NTRODUCTION1
Plaintiff Yakar Technologies, LLC (“Yakar”) filed its complaint in this case on June 24,
2025, alleging that Defendant DAS Companies, Inc. (“DAS”) infringed on U.S. Patent Nos.
9,845,058 (“’058 Patent”) and 11,034,309 (“’309 Patent”).2 DAS filed its answer and
counterclaims on July 21, 2025.3 Yakar answered DAS’s counterclaims on August 1, 2025.4
On October 17, 2025, DAS filed an ex parte request for reexamination of the ’058 Patent
with the United States Patent and Trademark Office (“USPTO”). The USPTO issued an
Electronic Acknowledgment Receipt for DAS’s request the same day.5

U.S.C. § 636(b)(1)(A). ECF No. 11.

DAS has also prepared an ex parte request for reexamination of the ’309 Patent6 but was
unable to file it because, prior to the filing of Yakar’s complaint, the USPTO identified the ’309
Patent as expired for nonpayment of maintenance fees by the patent owner.7 Yakar filed a
petition to revive the ’309 Patent, but the USPTO dismissed that petition on October 21, 2025.8
Yakar filed a second petition to revive the ’309 Patent on October 29, 2025.9 DAS asserts that, in
the event Yakar successfully revives the ’309 Patent, DAS will promptly file its ex parte request
for reexamination of that patent.
DAS now moves to stay this case pending completion of the reexamination proceedings
before the USPTO.10 Yakar opposed DAS’s motion.11 DAS replied, noting, among other things,
that the USPTO has granted a third party’s request for reexamination of the ’058 Patent.12
ANALYSIS
The court grants DAS’s motion to stay this case pending completion of the reexamination
proceedings before the USPTO. “The Federal Circuit has recognized that a district court may
properly stay proceedings in a patent case pending the [USPTO]’s reexamination of a patent by
6 ECF No. 25-2.
7 Because the USPTO has identified the ’309 Patent as expired, DAS cannot submit its ex parte
request for reexamination for that patent. 37 C.F.R. § 1.510(a) (providing that an ex parte request
for reexamination of a patent may be filed “during the period of enforceability” of the patent).

that Office.”13 Further, “[c]ourts have recognized that ‘there is a liberal policy in favor of
granting motions to stay proceedings pending the outcome of USPTO reexamination
proceedings.’”14 There are
three factors courts routinely employ in determining whether to stay
a patent infringement action pending reexamination: (1) whether a
stay will simplify the issues in question and trial of the case;
(2) 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.15
As shown below, each factor weighs in favor of granting DAS’s motion.
Under the first factor, a stay will simplify the issues in this case. “[C]ourts have
recognized that the reexamination process is beneficial in the ‘simplification of litigation that
might result from the cancellation, clarification, or limitation of claims, and, even if the
reexamination did not lead to claim amendment or cancellation, it could still provide valuable
analysis to the district court.’”16 Here, the USPTO has already granted a third party’s ex parte
request for reexamination of the ’058 Patent, which demonstrates that there is a question of
patentability affecting each claim of the ’058 Patent and shows a strong likelihood that DAS’s ex

parte request for reexamination of the ’058 Patent will be granted. The USPTO’s analysis in the
reexamination proceedings will inform the court about the scope of infringement and claim
construction for the ’058 Patent. Thus, a stay pending completion of those reexamination
proceedings will simplify the issues in this case concerning the ’058 Patent.
With respect to the ’309 Patent, Yakar concedes that patent was expired prior to Yakar
initiating this case and that the USPTO denied Yakar’s first petition to revive that patent. Further,
Yakar admits that it has filed a second petition to revive the ’309 Patent that has not yet been
decided by the USPTO. If that second petition is denied, the ’309 Patent will remain expired and
unenforceable and, consequently, cannot form the basis for Yakar’s claims of patent
infringement. If the second petition is granted, DAS asserts that it will promptly file its ex parte
request for reexamination of the ’309 Patent. Thus, regardless of the outcome of the second
petition, a stay will help simplify the issues in this case relative to the ’309 Patent. Accordingly,
the first factor weighs in favor of a stay.
As to the second factor, this case is in its relative infancy. DAS asserts—and Plaintiff
does not contest—that the parties have engaged in very little written discovery, no depositions
have been taken, no claim construction briefing is scheduled, and no trial date has been set.
Therefore, this factor likewise weighs in favor of a stay.
Considering the third factor, a stay would not impose undue prejudice on or present a
clear tactical disadvantage to Yakar. Although there may be some resulting prejudice to Yakar by
imposing a stay, “[c]ourts have found that the ‘delay inherent in the reexamination process does

not constitute, by itself, undue prejudice.’”17 Additionally, Yakar has not moved for injunctive
relief in this case, which undercuts any of its arguments about prejudice. Indeed, “‘[m]any courts
have found . . . that attempts by a patentee to argue undue prejudice are undermined if the
patentee has elected not to pursue preliminary injunctive relief.’”18 Thus, Yakar’s “‘prior lack of
urgency in this matter belies [any] insistence that the litigation move forward with all dispatch
now.’”19
A stay would also not present any clear tactical disadvantage to Yakar. Yakar contends
that a stay confers a tactical advantage upon DAS because “[c]ontinued infringement erodes
Yakar’s ability to license” the ’058 Patent and the ’309 Patent “and allows DAS to profit from”
those patents.20 However, Yakar has not sought injunctive relief and fails to argue that an award
of monetary damages would be insufficient to make it whole, both of which undermine its
argument about any clear tactical disadvantage.21 Accordingly, the third factor weighs in favor of
a stay.
