MEMORANDUM OPINION
This action, filed by Plaintiff Barbara Sopkin, see generally Compl., ECF No. 1-1 at 3–
35, proceeding pro se and in forma pauperis (“IFP”), was removed to this District from the
Superior Court of the District of Columbia, by Defendant John Lopatto, see Def.’s Not. of
Removal (“NOR”), ECF No. 1. Lopatto then filed a Motion to Dismiss (“MTD”), ECF No. 8,
and supporting Memorandum (“MTD Mem.”), ECF No. 8-1, which Sopkin opposes, see Pl.’s
Opposition to MTD (“Opp’n to MTD”), ECF No. 12, and moves to strike, see Pl.’s Mot. to
Strike (“MTS”), ECF No. 14. Sopkin has also filed a Motion for Partial Summary Judgment
(“MPSJ”), ECF No. 16, and a Motion to Remand to Superior Court (“MTR”), ECF No. 17, both
of which are opposed by Lopatto, see Def.’s Opposition to MPSJ, ECF No. 19; Def.’s
Opposition to MTR, ECF No. 20. For the reasons explained below, Sopkin’s Motion to Remand
is granted. The remaining motions are all held in abeyance for resolution by the Superior Court.
BACKGROUND
1 This is not the first matter involving these parties; this case is the fifth action overall, and
now the second lawsuit by Sopkin against Lopatto in this District. 1
Lopatto is a citizen of Virginia who maintains a law firm in the District of Columbia, and
previously represented Sopkin, an Israeli citizen, as an assignee of Interlase, L.P., in three
separate lawsuits. See id.; NOR ¶¶ 13–14; Compl. at caption, ¶¶ 1, 15, 67; Compl. Ex. 20, ECF
No. 1-1, at 81–38 (Fee Agreement, dated Dec. 15, 2016) (“FA I”); Compl. Ex. 21, ECF No. 1-1,
at 84–86 (Fee Agreement, Dated Aug. 27, 2021) (“FA II”). In Sopkin I, II, and III, Sopkin
challenged the management of Interlase, a Georgia limited partnership that once held a corporate
license agreement for specialized catheter patents in exchange for royalties. See Sopkin, 2023
WL 5833679, at *1–4. Sopkin purports to have long maintained an ownership interest in
Interlase, originally conveyed to her by Lucre Investments, Ltd. See Sopkin, 2023 WL 5833679,
at *1–4. In those three lawsuits, Sopkin alleged that Interlase’s former receiver, Richard
Mendelson, failed to extend Interlase’s patents, negligently under-collected royalty payments,
and permitted licensees to under-report the sales upon which those royalties were calculated,
costing Interlase millions of dollars. See id.
None of those lawsuits were decided in Sopkin’s favor, and on October 27, 2022, she
filed Sopkin IV against Lopatto in this District, raising claims for legal malpractice based on
diversity jurisdiction, and alleging that, due to ineffective legal strategy, namely, failure to raise a
1 See Sopkin v. Lopatto, No. 22-cv-03300, 2023 WL 5833679, at *2–5 (D.D.C. Sept. 8, 2023) (“Sopkin IV”) (memorializing litigation history); see also Sopkin v. Mendelson, et al., No. 16-cv- 01146, 2017 WL 1536434 (E.D. Va. Apr. 27, 2017) (“Sopkin I”), aff’d, 746 Fed. Appx. 157 (4th Cir. 2018) (per curiam); Sopkin v. Mendelson, et al., No. 19-cv-58, 2019 WL 13251310 (E.D. Va. May 2, 2019) (“Sopkin II”), aff’d, 847 Fed. Appx. 197 (4th Cir. 2021) (per curiam); see Sopkin v. Mendelson, et al., No. CL-20004925-00 (Arlington Co. Cir. Ct. filed Dec. 1, 2020) (“Sopkin III”). 2 “surcharge theory” under Virginia law, Lopatto was responsible for her inability to recover
Interlase’s $11,963,416 in lost patent-royalty payments. See id. at *5. She also claimed that
Lopatto owed her for sanctions totaling $62,854.24, entered against her by the United States
District Court for the Eastern District of Virginia in Sopkin I, because of allegedly frivolous
claims he advanced on her behalf. See id.; see also Sopkin, 2022 WL 4002310 (E.D. Va. Sept. 1,
2022) (entering sanctions), aff’d, No. 22-1992, 2024 WL 1108825 (4th Cir. Mar. 14, 2024).
On September 8, 2023, this court entered a Memorandum Opinion and Order granting
Lopatto’s Motion to Dismiss, dismissing the matter in full for want of subject matter jurisdiction.
See id. at *11. In its Memorandum Opinion, the court detailed the relevant factual and
procedural history, see id. at *1–4, and that Opinion is incorporated in full by reference herein, 2
see id. at *1–11.
In short, the court held that, despite holding herself out as the sole owner of Interlase,
Sopkin could not recover the $11,963,416 in lost patent-royalty payments because, if they were
owed, they belonged entirely to the entity. See id. at *6–9. First, the court found that Sopkin
was prohibited from bringing any claims on behalf of Interlase. See id. at *7, *9. Three previous
courts––the United States Court of Appeals for the Fourth Circuit, the Eastern District of
Virginia, and the Arlington County Circuit Court––all previously ruled that Sopkin lacked
standing to raise claims for Interlase. See id. at *7. More specifically, those courts found that
2 A court may “take judicial notice of related proceedings and records in cases before the same court.” Valore v. Islamic Republic of Iran, 700 F. Supp. 2d 52, 59 (D.D.C. 2010) (quoting Brewer v. Islamic Rep. of Iran, 664 F. Supp. 2d 43, 50–51 (D.D.C. 2009); Heiser v. Islamic Republic of Iran, 466 F. Supp. 2d 229, 267 (D.D.C. 2006); citing Fed. R. Evid. 201(b); Booth v. Fletcher, 101 F.2d 676, 679 n.2 (D.C. Cir. 1938) (“A court may take judicial notice of, and give effect to, its own records in another but interrelated proceeding[.]”) (other citation omitted)), cert. denied sub nom. Fletcher v. Booth, 307 U.S. 628 (1939). 3 Sopkin was so prohibited due to an injunction entered by the Arlington County Circuit Court on
December 18, 1998, declaring Lucre a sham entity, and enjoining Lucre, its officers, managers,
directors, and agents, from claiming to be Interlase’s partner, or taking any actions on its behalf.
See id. at *1, *3. There was also no evidence to suggest that later conveyances (including those
executed by the inventor and founding partner, Dr. Fox) afforded Sopkin any legal or beneficial
interest in Interlase, or that she was otherwise qualified to bring a derivative suit. See id. at *3.
Because the issue of Sopkin’s standing had been repeatedly previously litigated, this court found
that Sopkin was collaterally estopped from relitigating the issue. See id. at *7.
Second, and notwithstanding the hurdle of collateral estoppel, this court found that
Sopkin could not sue on behalf of Interlase due to the “shareholder standing rule.” See id. The
court noted that no shareholder, not even a sole shareholder, has standing to sue in an individual
capacity on a claim that belongs to the entity, and that prohibition extends to sole owners of
limited partnerships. See id. at *6–7. Because the $11,963,416 in damages claimed by Sopkin
arose “directly from injuries sustained by Interlase—in fact, they were sustained entirely by the
entity—they d[id] not fall within any exception of the shareholder standing rule and . . . . [could
not] survive as pleaded, regardless of whether they [were] brought as a direct or derivative suit
against Mendelson, or whether they [were] brought as a derivative or direct legal malpractice suit
against Lopatto.” Id. at *7.
Third, the court found that Sopkin could neither join nor substitute Interlase as a plaintiff.
See id. at *8. Because Sopkin was proceeding pro se, she was ineligible to sue on behalf of
Interlase, and Interlase itself, as an artificial entity, could neither proceed pro se, nor apply to
proceed IFP. Id. at *9.
4 Finally, the court found that Sopkin appeared to have standing to bring her last remaining
claim for the sanctions-related damages because they were entered against her individually. Id.
at *9. But those damages fell $12,000 short of the $75,000 threshold required to establish
diversity jurisdiction. Id. For all these reasons, 3 Sopkin IV was dismissed pursuant to Federal
Rule 12(b)(1). Id. at *11.
Sopkin appealed, and on January 23, 2024, the United States Court of Appeals for the
District of Columbia Circuit affirmed. See Sopkin, No. 23-7115, 2024 WL 251537 (D.C. Cir.
Jan. 23, 2024) (per curiam) (“Mandate”). About two weeks later, on February 9, 2024, Sopkin
filed the instant matter against Lopatto in Superior Court, raising substantially similar claims to
those raised in Sopkin IV. See generally Compl. Sopkin again alleges that Lopatto committed
legal malpractice, demanding both the lost royalty payment damages––totaling $11,963,416, and
an award for the sanctions entered in Sopkin I––totaling $62,854.24. See id. ¶¶ 1–4, 14–15, 31–
37, 40–44, 54–55, 57–72, 75–80, 83–84.
New, however, are Sopkin’s claims that Lopatto allegedly breached their fee agreements
and committed fraud, in failing to pay (1) $30,000 in fees owed to Megan Nelson, CPA, an
accounting expert retained in 2021 in Sopkin III, see id. ¶¶ 54, 66, 81; Compl. Ex. 10, ECF No.
1-1, at 124–39 (Report of Megan Nelson, dated Nov. 5, 2021) (“Nelson Rep.”), and (2) $15,000
owed to Interlase, somehow relating to arbitration proceedings it initiated against Lopatto in the
London Court of International Arbitration (“LCIA”) in early 2022, see Compl. ¶¶ 38, 40, 82.
3 The court also alternatively found that, even if Sopkin had established subject matter jurisdiction, Sopkin IV should have been filed in the Eastern District of Virginia. See id. at *10– 11. 5 Finally, Sopkin presents a new legal theory, based on some new facts. See id. ¶¶ 2–6;
Opp’n to MTD at 2–5, 11–13. She contends that from October 25, 2022 to January 24, 2024, she
was the legal owner of Interlase’s patent rights and assumed the right to sue for any of the
entity’s losses, as a result of a deed of gift executed between them on October 25, 2022. See id.;
Compl. Ex. 23, ECF No. 1-1, at 76–77 (Oct. 25, 2022 Deed of Gift) (“Deed I”). Then, on
January 24, 2024, Sopkin conveyed those rights back to Interlase through a second deed of gift,
see Compl. ¶¶ 2–6; Compl. Ex. 25, ECF No. 1-1, at 69–70 (Jan. 24, 2024 Deed of Gift) (“Deed
II”), only for Interlase to then convey them right back to Sopkin on January 27, 2024, by a third
deed of gift, see Compl. ¶¶ 2–6; Compl. Ex. 27, ECF No. 1-1, at 64–68 (Jan. 27, 2024 Deed of
Gift) (“Deed III”); Opp’n to MTD at 2–5, 11–13. Sopkin argues that, while active, the first deed
of gift allowed her to sue on behalf of Interlase, and the second and third deeds of gift now allow
her to bring both direct and derivative suit on its behalf. See Compl. ¶¶ 2–6; Opp’n to MTD at
2–5, 12–13.
On March 14, 2024, Lopatto removed this matter to this District based on diversity
jurisdiction, 28 U.S.C. §§ 1332(a)(2), 1441(b), 1446(c); see NOR ¶¶ 3, 9, 11–18, then promptly
moved to dismiss for lack of subject matter jurisdiction, see MTD Mem. at 10–18, and failure to
state a claim, see id. at 11–12, 18–28. In response, Sopkin moves to remand, arguing that this
court is without subject matter jurisdiction because, inter alia, the amount in controversy once
again falls short of $75,000. See MTR at 2–3; MTS at 3. Despite this contention, Sopkin also
moves for partial summary judgment on her sanctions-related claim, seeking an award for
$62,854.24. See MPSJ at 2–4.
LEGAL STANDARDS
6 Subject Matter Jurisdiction 4
“Article III of the Constitution prescribes that ‘[f]ederal courts are courts of limited
subject-matter jurisdiction’ and ‘ha[ve] the power to decide only those cases over which
Congress grants jurisdiction.’” Bronner v. Duggan, 962 F.3d 596, 602 (D.C. Cir. 2020)
(alterations in original) (quoting Al-Zahrani v. Rodriguez, 669 F.3d 315, 317 (D.C. Cir. 2012));
see Gunn v. Minton, 568 U.S. 251, 256 (2013) (“‘Federal courts are courts of limited
jurisdiction,’ possessing ‘only that power authorized by Constitution and statute.’”) (quoting
Kokkonen v. Guard. Life Ins. Co. of Am., 511 U.S. 375, 377 (1994)).
A defect in “standing is a defect in subject matter jurisdiction.” Haase v. Sessions, 835
F.2d 902, 906 (D.C. Cir. 1987); see Lujan v. Defenders of Wildlife, 504 U.S. 555, 560 (1992)
(noting that “the core component of standing is an essential and unchanging part of the case-or-
controversy requirement of Article III”). Furthermore, “[t]he defense of res judicata is [also]
jurisdictional in character.” Rizvi v. McClure, 597 F. Supp. 2d 63, 66 (D.D.C. 2009) (citing
Stanton v. D.C. Ct. of Appeals, 127 F.3d 72, 77 (D.C. Cir. 1997)). Therefore, “a motion for
dismissal based on res judicata properly falls under Federal Rule of Civil Procedure 12(b)(1).”
Id.
To survive a challenge to subject matter jurisdiction, the plaintiff bears the burden of
demonstrating a court’s subject-matter jurisdiction. Arpaio v. Obama, 797 F.3d 11, 19 (D.C. Cir.
2015), cert. denied, 577 U.S. 1103 (2016); see also Hertz Corp. v. Friend, 559 U.S. 77, 96–97
(2010); Thomson v. Gaskill, 315 U.S. 442, 446 (1942). When considering a motion to dismiss
4 Because the court finds that it lacks subject matter jurisdiction over this matter, it does not reach Lopatto’s arguments for failure to state a claim. See U.S. ex rel. Settlemire v. Dist. of Columbia, 198 F.3d 913, 920–21 (D.C. Cir. 1999).
7 under Rule 12(b)(1), a court must accept as true all uncontroverted material factual allegations
contained in the complaint and “‘construe the complaint liberally, granting plaintiff the benefit of
all inferences that can be derived from the facts alleged’ and upon such facts determine
jurisdictional questions.” Am. Nat'l Ins. Co. v. FDIC, 642 F.3d 1137, 1139 (D.C. Cir. 2011)
(quoting Thomas v. Principi, 394 F.3d 970, 972 (D.C. Cir. 2005); Barr v. Clinton, 370 F.3d
1196, 1199 (D.C. Cir. 2004)). A court need not accept inferences drawn by the plaintiff,
however, if those inferences are unsupported by facts alleged in the complaint or amount to legal
conclusions. See Browning v. Clinton, 292 F.3d 235, 242 (D.C. Cir. 2002).
To that end, in assessing a challenge to subject matter jurisdiction under Rule 12(b0(1), a
court may consider documents outside the pleadings. See Land v. Dollar, 330 U.S. 731, 735 n.4
(1947); Haase, 835 F.2d at 906. In doing so, a court does not convert the motion into one for
summary judgment; “the plain language of Rule 12(b) permits only a 12(b)(6) motion to be
converted into a motion for summary judgment” when a court considers documents extraneous
to the pleadings. Haase, 835 F.2d at 905.
Remand
State court civil actions may be removed to a United States district court by the
defendant, provided the case could have originally been filed in federal court. See 28 U.S.C. §
1441(a). A defendant may remove an action to federal court when original subject matter
jurisdiction exists in diversity. See id. § 1441(b); Caterpillar, Inc. v. Williams, 482 U.S. 386,
392 (1987). Diversity jurisdiction exists when the action involves parties from different states,
and the amount in controversy exceeds $75,000.00 per plaintiff, exclusive of interest and costs.
See 28 U.S.C. § 1332(a); Carden v. Arkoma Assocs., 494 U.S. 185, 187 (1990).
8 Court are obligated to construe federal removal statutes strictly to avoid federalism
concerns, see Shamrock Oil & Gas Corp. v. Sheets, 313 U.S. 100, 107–09 (1941), and any
ambiguities concerning the propriety of removal must be resolved in favor of remand, Hood v. F.
Hoffman–La Roche, Ltd., 639 F. Supp. 2d 25, 28 (D.D.C. 2009) (citing Gasch v. Hartford
Accident & Indem. Co., 491 F.3d 278, 281–82 (5th Cir. 2007)). “If at any time before final
judgment it appears that the district court lacks subject matter jurisdiction, the case shall be
remanded.” 28 U.S.C. § 1447(c).
A challenge to subject matter jurisdiction may be raised on a motion to remand. See id.
A “party opposing a motion to remand bears the burden of establishing that subject matter
jurisdiction exists in federal court.” Int’l Union of Bricklayers & Allied Craftworkers v. Ins. Co.
of The West, 366 F. Supp. 2d 33, 36 (D.D.C. 2005) (citation omitted); see also Wilson v.
Republic Iron & Steel Co., 257 U.S. 92, 97–98 (1921).
DISCUSSION
Once again, as explained below, this court is without jurisdiction over any of Sopkin’s
claims.
I. Lost Patent-Royalty Payments
As discussed in Sopkin IV, Sopkin cannot pursue the $11,963,416 in patent royalty
payments, allegedly lost due to Lopatto’s failure to timely raise the surcharge theory. See
Sopkin, 2023 WL 5833679, at *6–8. It is uncontroverted that, if owed, those payments belong
entirely to Interlase, see Compl. ¶¶ 3, 64; Opp’n to MTD at 5–6, 8–11, and Sopkin has no
standing to bring claims on its behalf, see Sopkin, 2023 WL 5833679, at *6–8. The shareholder
standing rule bars Sopkin’s direct claims, and the clear precedent recognizing her overall lack of
standing bars claims of any kind by Sopkin for Interlase. See id.
9 II. Arbitration-Related Damages
Likewise, Sopkin has no standing to raise her claim for the $15,000 in arbitration-related
damages. She broadly alleges that Lopatto “cost Interlase at least $15k” arising from Lopatto’s
alleged refusal to participate in LCIA proceedings. See Compl. ¶ 38 (emphasis added); see also
Opp’n to MTD at 9 (insisting that the fee agreements were executed strictly for Interlase). In
other words, Sopkin does not allege that she personally expended $15,000; instead, she contends
that the entity is owed that amount. See id. Compl. ¶¶ 38, 40; see also Opp’n to MTD at 9.
Thus, for the same reasons Sopkin is without standing to pursue the lost patent royalty payments,
she is also without standing to pursue the arbitration-related damages on Interlase’s behalf. See
Sopkin, 2023 WL 5833679, at *6–8.
In addition, the arbitration-related damages are barred by collateral estoppel. See Taylor
v. Sturgell, 553 U.S. 880, 892 (2008) (collateral estoppel bars “successive litigation of an issue of
fact or law actually litigated and resolved in a valid court determination essential to the prior
judgment, even if the issue recurs in the context of a different claim.”). Although under the
“curable defect” exception to collateral estoppel, a litigant “whose claim[ ] [was] dismissed on
jurisdictional grounds” is not precluded from re-litigating that dismissal “if a material change
following dismissal cured the original jurisdictional deficiency[,]” Nat’l Ass'n of Home Builders
v. EPA, 786 F.3d 34, 41 (D.C. Cir. 2015), the alleged financial injuries arising from the LCIA
proceedings occurred prior to the dismissal in Sopkin IV, see, e.g., Sopkin, No. 22-cv-03300, at
Compl. (“Sopkin IV Compl.”), ECF No. 1, ¶ 57 (noting that Interlase raised legal malpractice
claims against Lopatto in the LCIA six months before filing Sopkin IV, “but Lopatto reneged on
his legal obligations to pay for parts of that arbitration” and those proceedings would be
imminently dismissed without prejudice).
10 Accordingly, because the arbitration-related damages preceded the dismissal of Sopkin
IV, they fail to qualify under the curable defect exception, and do not confer standing. See
Swanson Grp. Mfg. LLC v. Jewel, 195 F. Supp. 3d 66, 75 (D.D.C. 2016) (finding that “pre-
existing” or “ongoing” injuries “do not satisfy the requirements for the curable defect exception”
to remedy standing); Ricks v. Simons, 759 F. Supp. 918, 921 n.4 (D.D.C. 1991) (finding that the
plaintiff “could have foreseen that [an] issue would arise in later litigation[;]” therefore,
collateral estoppel barred its subsequent litigation) (citing Kremer v. Chemical Constr. Corp.,
456 U.S. 461, 468, n.6 (1982)).
Moreover, Sopkin’s mere mention of the arbitration-related damages in Sopkin IV,
without having formally raised them as a claim, does not suffice to salvage them. See Nat’l
Ass’n of Home Builders, 786 F.3d at 43 (holding that a court’s previous decision “cannot be
used as a mere instruction manual on how [a plaintiff] might correct defects in its claim of
standing by doing a better job of pleading preexisting facts and arguing the law more forcefully
in a new case.”); Newdow v. Bush, 355 F. Supp. 2d 265, 275 (D.D.C. 2005) (finding that “a mere
‘defect in pleading’ in the original complaint cannot be remedied through the ‘curable defect’
doctrine.”) (quoting Dozier v. Ford Motor Co., 702 F.2d 1189, 1192 (D.C. Cir. 1983)).
For all these reasons, Sopkin lacks standing to raise a claim for the arbitration-related
damages.
III. Expert-Related Damages
Sopkin asserts that Lopatto owes her $30,000 in fees purportedly due to expert witness,
Nelson. See Compl. ¶¶ 54, 66, 81. Nelson was retained in 2021 in Sopkin III, see id. ¶¶ 54, 66,
81, and her report was complete by November 5, 2021, see Nelson Rep. Once again, for the
same reasons expressed above, the expert-related damages fail to qualify under the curable defect
11 exception, because the fees owed to Nelson, if any, were known prior to Sopkin IV, which was
filed nearly a year later, see Sopkin IV Compl.
Furthermore, assuming Sopkin could overcome collateral estoppel, and that she is even a
party to the relevant fee agreements, compare Opp’n to MTD at 9 (Sopkin arguing that the fee
agreements were executed only for Interlase), with MTD Mem. at 4 n.3 (Lopatto arguing that the
fee agreements were executed for Sopkin), she has also nonetheless failed to allege any injury
arising from this claim and therefore lacks standing to raise it.
Federal courts have subject matter jurisdiction only if there exists a “case” or
“controversy,” and in the absence of any actual or threatened injury, no case or controversy
exists. See U.S. Const. Art. III, § 2. The alleged “injury must be ‘concrete, particularized, and
actual or imminent; fairly traceable to the challenged action; and redressable by a favorable
ruling.’” Clapper v. Amnesty Int'l USA, 568 U.S. 398, 409 (2013) (quoting Monsanto Co. v.
Geertson Seed Farms, 561 U.S. 139, 149–50 (2010)). Moreover, standing cannot be “based on .
. . fears of hypothetical future harm that is not certainly impending.” Id. at 417 (citing
Pennsylvania v. New Jersey, 426 U.S. 660, 664 (1976) (per curiam); Nat’l Fam. Planning &
Reprod. Health Assn., Inc., 468 F.3d 826, 831 (D.C. Cir. 2006)).
Here, the fee agreements clearly state that “the client,” not Lopatto, is responsible for
payment of expert fees. See FA I ¶ 3; FA II ¶ 6. Lopatto attests that, despite that provision, he
advanced “Ms. Nelson’s expert witness fees in the amount of $20,000[,]” Decl. of John Lopatto
(“Lopatto Decl.”), ECF No. 8-25, ¶ 5, and that Sopkin has not reimbursed him, despite her
obligation, id. ¶ 6. In response, Sopkin speculates that Nelson may be owed additional payment,
and surmises that any outstanding fees “may cost money to Sopkin if Nelson’s testimony as it
concerns the damages is required in this case.” See Opp’n to MTD at 13 (emphasis added); see
12 also Compl. ¶¶ 54, 66. But Lopatto has attested that he has paid Nelson’s fees, see Lopatto Decl.
¶ 5, and there is no allegation that Nelson has demanded any payment from Sopkin. And, if
remaining fees are still owed to Nelson, or if her testimony should be later required––both
completely conjectural premises––either Sopkin or Interlase would be responsible for payment,
not Lopatto. See FA I ¶ 3; FA II ¶ 6.
Because Sopkin has failed to present a dispute “of sufficient immediacy and reality[,]”
Golden v. Zwickler, 394 U.S. 103, 109 (1969), and relies on a “hypothetical state of facts[,]”
Aetna Life Ins. Co. of Hartford, Conn. v. Haworth, 300 U.S. 227, 241 (1937) (collecting cases),
contradicted by the record, she has no standing to seek the expert-related damages, and for all of
the above-stated reasons, this court is without subject matter jurisdiction over that claim.
IV. Deeds of Gift
Sopkin’s new theory that the “deeds of gift” allow her to bring suit for Interlase is
without merit. As repeatedly discussed, multiple courts have determined that Sopkin has no
standing to bring claims on behalf of Interlase. See Sopkin, 2023 WL 5833679, at *3–4, 9.
Because of her original association with Lucre, she was dispossessed of any legal interest in
Interlase, and her subsequent attempts to regain ownership were unavailing. See id. Those
previous decisions continue to have preclusive effect. See id. at *7; see also U.S. Bank Nat’l
Ass’n v. Poblete, No. 15-312, 2016 WL 1089217, at *7, *11–12, *11 n.12 (D.D.C. Mar. 18,
2016) (applying offensive collateral estoppel in fifth lawsuit, and holding that defendant, who
claimed ownership of real property as a trustee, could not oppose plaintiff’s action to quiet title
against that property despite having since registered a modified deed, because the D.C. Circuit
previously determined that the trust lacked valid title to the property and defendant thus lacked
standing).
13 Moreover, even if these deeds of gift could, on their own, defeat collateral estoppel, they
are defective for several reasons. The first deed of gift was purportedly conveyed to Sopkin on
October 25, 2022, just two days before she filed Sopkin IV in this court. Compare Deed I, with
Sopkin IV Compl., ECF No. 1. Despite the central issue of her standing, Sopkin never once
mentioned the first deed of gift in Sopkin IV, a fact she admits, see Compl. ¶ 2–3; Opp’n to MTD
at 2–5, 11–13; she raised it for the very first time with the D.C. Circuit while briefing her appeal
of Sopkin IV, see Sopkin, 2024 WL 251537, at *1 (noting that Sopkin “argue[d] for the first time
in her opening brief that she ha[d] standing . . . pursuant to a deed of gift purportedly executed
days before the underlying complaint was filed. This theory of standing was not raised in district
court and [was] therefore forfeited.”). It is unclear why Sopkin failed to introduce––or even
reference––the first deed of gift in Sopkin IV, particularly given its purported recency, and her
otherwise painstakingly detailed accounts of Interlase’s history and chain of ownership.
In any event, despite her arguments to the contrary, see Opp’n to MTD at 2–4, Sopkin’s
reliance on the first deed of gift post factum does not fall under the curable defect exception, see
Yamaha Corp of America v. U.S., 961 F.2d 245, 254–55 (D.C. Cir. 1992) (“[Issue] [p]reclusion
cannot be avoided simply by offering evidence in the second proceeding that could have been
admitted, but was not, in the first.”) (citation omitted), cert. denied, 506 U.S. 1078 (1993); Sec.
Indus. Ass’n v. Bd. of Govs., 900 F.2d 360, 364 (D.C. Cir. 1990) (a plaintiff may not raise new
argument in second proceeding if it was never made in first proceeding; so long as argument
could have been made, it is precluded)); Dozier, 702 F.2d at 1192 (finding that plaintiff could not
overcome collateral estoppel to cure standing in diversity action by later changing his “sworn
recitation of past facts.”) (fn. omitted); Campaign Legal Ctr. v. Fed. Elec. Comm., No. 22-cv-
3319, 2023 WL 6276634, at *11 (D.D.C. Sept. 26, 2023) (finding that the plaintiffs’ previous
14 “failure to highlight [] information” that could have plausibly cured their defect in standing was
“puzzling” and that the prohibition against introduction of that information in a subsequent
lawsuit “is the reason issue preclusion exists.”); see also UMC Develop., LLC v. Dist. of
Columbia, 401 F. Supp. 3d 140, 156–57 (D.D.C. 2019) (finding that “only claim preclusion, not
issue preclusion, requires a ‘final, valid judgment on the merits[,]’ ”) (quoting Nat. Res. Def.
Council v. EPA, 513 F.3d 257, 260 (D.C. Cir. 2008); Nat’l Ass’n of Home Builders, 786 F.3d at
41) (a “jurisdictional dismissal does not involve an adjudication on the merits,” but it still
“adjudicate[s] the court’s jurisdiction, and a second complaint cannot command a second
consideration of the same jurisdictional claims.”)).
Sopkin, appearing to recognize this obstacle, focuses largely on the third deed of gift.
See Compl. ¶ 6; Opp’n to MTD at 4–5, 11–13. The second deed of gift, conveying the rights
back to Interlase, was purportedly executed the day after the D.C. Circuit affirmed Sopkin IV,
compare Deed II, with Mandate, and then the third deed of gift was conveyed to Sopkin mere
days later, see Deed III. But the third deed of gift falls well short of overcoming the shareholder
standing rule and providing Sopkin derivative status. See Sopkin, 2023 WL 5833679, at *6–7.
The third deed of gift was executed well after Lopatto’s alleged wrongful acts; therefore, Sopkin
is barred by the contemporaneous ownership requirement of the shareholder standing rule, which
mandates that a plaintiff bringing a derivative suit must have been an owner at the time of the
challenged acts or omissions. See First Am. Corp. v. Al-Nahyan, 17 F. Supp. 2d 10, 20 (D.D.C.
1998).
The contemporaneous ownership requirement “is designed to avoid so-called ‘strike
suits’ and other speculative litigation.” Id. It is recognized federally, see Fed. R. Civ. P.
23.1(a)–(b)(1), and in all three local jurisdictions relevant to this case––the District of Columbia,
15 Georgia, and Virginia, and extends to limited partnerships, see D.C. Code §§ 29–301.02(22), 29–
305.51(A)(1); D.C. Super. Ct. R. 23.1(a)–(b)(1); Trust Agreement of Steven M. Sushner v. C.A.
Harrison Comanies, LLC, No. 22-cv-2837, 2023 WL 6313507, at *6, *11 (D.D.C. Sept. 28,
2023) (applying D.C. law); Levant v. Whitley, 755 A.2d 1036, 1047 n.14 (D.C. 2000) (“[D.C.
Super. Ct.] Rule 23.1 is virtually identical to Fed. R. Civ. P. 23.1.”); Ga. Code §§ 14-2-140(11),
14-2-741(1); Hurt v. Cotton States Fertilizer Co., 145 F.2d 293, 295 (5th Cir. 1944) (applying
federal and Georgia law), cert. denied sub nom. Cotton State Fertilizer Co v. Hurt, 324 U.S. 844
(1945); Smith v. Coolidge Banking Co., 92 S.E. 519, 519 (Ga. Sup. Ct. 1917); Va. Code §§ 13.1–
672.1(1), 50–73.62, 50-73.63; Milstead v. Bradshaw, No. C96–1498, 1997 WL 33616661, at *2
(Va. Cir. 1997).
Here, Lopatto’s alleged wrongdoing occurred years before the third deed of gift. For
example: (1) Interlase attempted to arbitrate against Lopatto for legal malpractice in “early
2022,” see Compl. ¶ 32, (2) Sopkin III was dismissed on March 8, 2022, see Sopkin, No. CL-
20004925-00, at Final Order (entered Mar. 8, 2022); and (3) Lopatto withdrew his appearance in
Sopkin I on August 3, 2022, see Sopkin, No. 16-cv-01146, ECF No. 175 (Order Granting
Lopatto’s Motion to Withdraw as Attorney). Because Sopkin’s ownership was not
contemporaneous, 5 she cannot bring a derivative suit.
Furthermore, these deeds of gift did not transfer Interlase’s interests to Sopkin by
operation of law, because the conveyances were not made to Sopkin by an existing owner, see
Fed. R. Civ. P. 23.1(b)(1); D.C. Sup. Ct. R. 23.1(b)(1); D.C. Code 29–305.51(1); Ga. Code § 14-
2-741(1); Va. Code § 13.1-672.1(2)–(3). They were, for all intents and purposes, executed
5 To the extent Sopkin relies on the first deed of gift, its conveyance also occurred after Lopatto’s alleged acts and omissions. See Deed I. 16 between Sopkin and herself, without any exchange of consideration. See Deed I; Deed II; Deed
III. Moreover, Sopkin did not possess any ownership rights to convey. See Sopkin, 2023 WL
5833679, at *3, *9; see also Compl. ¶¶ 2 (“There was a period of time between October 25,
2022, and January 25, 2024, that Sopkin owned [the patents] and rights to same, but she did not
own any of that property or rights to same, at the very least, prior to October 25, 2022, and
between January 25 and January 27, 2024.”), ¶ 3 (noting that she is not asserting the “theory of
her underlying ownership”). Simply put, these conveyances are null, and thus fail to establish
that Sopkin can fairly and adequately represent Interlase’s interests. See Fed. R. Civ. P. 23.1(a);
D.C. Sup. Ct. R. 23.1(a); D.C. Code 29–305.51(2); Ga. Code § 14-2-741(2); Va. Code § 13.1-
672.1(4).
Additionally, per Sopkin’s own admission, the deeds were executed specifically to cure
defects in her standing, see Compl. ¶¶ 2–3; Opp’n to MTD at 2–4, but a conveyance conducted
for the purpose of conferring jurisdiction when it is otherwise lacking is “collusive” and
untenable. See Fed. R. Civ. P. 23.1(b)(2); D.C. Sup. Ct. R. 23.1(b)(2); see also First Am. Corp.,
17 F. Supp. 2d at 20 (finding that the court is obligated to “look beyond the corporate form to
examine the economic realities of a transfer of ownership so as to prevent an abuse of the legal
fiction that treats a corporation as a separate juridical entity.”).
Indeed, this is not the first time that Sopkin has unsuccessfully attempted this maneuver
to cure her standing problems. See Sopkin, 746 Fed. Appx. at 161 n.8. In affirming Sopkin I, the
Fourth Circuit found that Sopkin had not met the requirements of Federal Rule 23.1 because she
“obtained her interest in Interlase . . . solely for the purpose of litigation[,]” and the record
instead reflected that “Interlase’s assets had [already] been liquidated in the bankruptcy
proceedings by the time that Dr. Fox purportedly assigned his interest in Interlase to Sopkin.”
17 Id. Sopkin cannot now reattempt the same stratagem here. See Cohen v. Beneficial Indus. Loan
Corp., 337 U.S. 541, 556 (1949) (holding that a court shall not “permit itself to be used to litigate
a purchased grievance or become a party to speculation in wrongs done to corporations[,]” and
requiring plaintiff to show, under Fed. R. Civ. P. 23.1, “that an action is not a collusive one to
confer jurisdiction and to set forth the facts showing that the plaintiff has endeavored to obtain
his remedy through the corporation itself.”); see Sopkin, 746 Fed. Appx. at 160–61 n.7 (same)
(collecting cases).
For all of these reasons, the deeds of gift, whether direct or derivative, fail to overcome
Sopkin’s defects in standing to bring suit for Interlase 6.
V. Sanctions-Related Damages & Remand
Once again, all that remains is Sopkin’s sanctions-related claim totaling $62,854.24. See
Compl. ¶¶ 1–4, 14–15, 31–37, 40–44, 54–55, 57–72, 75–80, 83–84. The court once more finds
that, while Sopkin still appears to have standing to bring that claim because the sanctions were
awarded against her individually, see Sopkin, 2022 WL 4002310, at *1, *1 n.1, *3, those
damages are more than $12,000 short of the $75,000 requirement to satisfy the requirements for
diversity jurisdiction, see 28 U.S.C. § 1332(a); see also Sopkin, 2023 WL 5833679, at *9
(finding same).
However, unlike Sopkin IV, this matter did not originate in this court. Lopatto removed
this matter to this court, but then challenged subject matter jurisdiction––an inquiry that cuts
both ways, particularly because Sopkin has also moved to remand. Once challenged, a removal
6 More generally, Sopkin, who is once again proceeding pro se, cannot sue on behalf of Interlase, and Interlase, as an artificial entity, can neither proceed pro se, nor can it apply to proceed IFP. See Sopkin, 2023 WL 5833679, at *8 (citing cases). 18 based on diversity is only proper “‘if the district court finds, by the preponderance of the
evidence, that the amount in controversy exceeds’ the jurisdictional threshold.” Dart Cherokee
Basin Operating Co., LLC v. Owens, 574 U.S. 81, 88 (2014) (quoting 28 U.S.C. §
1446(c)(2)(B)).
Based on the evidence before it, and for all the reasons stated above, this court finds that
the amount in controversy is not satisfied for federal diversity jurisdiction. “When it appears that
a district court lacks subject matter jurisdiction over a case that has been removed from a state
court, the district court must remand the case.” Rep. of Venezuela v. Philip Morris Inc., 287 F.3d
192, 196 (D.C. Cir. 2002) (emphasis added) (citing 28 U.S.C. § 1447(c)); see Randolph v. ING
Life Ins. and Annuity Co., 486 F. Supp. 2d 1, 10 (D.C. Cir. 2007) (holding that, in a removed
case where the plaintiff lacked standing, the matter had to be remanded, and not dismissed, given
the clear “command” and “plain text of 28 U.S.C. § 1447(c)[.]”)).
This court is “[c]ognizant of the fact that the Superior Court for the District of Columbia
may also conclude that [Sopkin] lack[s] the requisite standing to pursue” the bulk of her “claims
in that forum,” but neither the D.C. Circuit nor the Supreme Court have recognized a “futility
exception” associated with § 1447(c); therefore, this court must “leave such a decision to the
discretion of the Superior Court, and remand this case[,]” See Randolph, 486 F. Supp. 2d at 10–
11; see also Int’l Primate Protection League v. Admins. of Tulane Educ. Fund, 500 U.S. 72, 89
(1991) (highlighting the mandatory nature of § 1447(c) and expressing reluctance to create a
futility exception). This principle is particularly relevant here because, assuming arguendo the
Superior Court agrees with this court’s conclusions, Sopkin may still have standing in Superior
Court for her sanctions-related claim.
CONCLUSION
19 For the reasons set forth above, Sopkin’s Motion to Remand is GRANTED. Lopatto’s
Motion to Dismiss, Sopkin’s Motion to Strike the Motion to Dismiss, and Sopkin’s Motion for
Partial Summary Judgment, shall all be HELD IN ABEYANCE to be decided by the Superior
Court upon remand. A separate Order is issued contemporaneously.
