MEMORANDUM OPINION

I. Introduction Pending before the court are two pro se motions to remand this case to the Summit County, Ohio Court of Common Pleas (“state court”) filed by plaintiff Derrick Martin King (“King”): (1) an omnibus motion to remand and for sanctions (Civ. No. 24-1693, ECF No. 4) filed on August 7, 2024, in the United States District Court for the Northern District of Ohio; and (2) after King’s case was transferred to this court by the Judicial Panel on Multidistrict Litigation (“JPML”) for pretrial proceedings as part of the Philips MDL, King filed a renewed motion to remand for lack of subject-matter jurisdiction in this court at the master Philips MDL docket on March 21, 2025 (Misc. No. 21-1230, ECF No. 3252), with brief in support (ECF No. 3253). The motions were thoroughly briefed. Philips RS North America LLC and Philips RS North America Holding Corp. (collectively, “Philips”) filed briefs in opposition to the motions (Civ. No. 24-1693, ECF No. 8; Misc. No. 21-1230, ECF No. 3286). King filed two reply briefs to support his omnibus motion (Civ. No. 24-1693, ECF Nos. 9, 25). Philips filed a response to the second reply (Civ. No. 24-1693, ECF No. 26) and King filed a third reply (Civ. No. 24-1693, ECF No. 27). King filed a reply brief in support of his second motion (Misc. No. 21-1230, ECF No. 3287). This court heard oral argument and testimony on the motions on May 6, 2025 (Transcript, Civ. No. 24-1693, ECF No. 34). The court orally denied King’s motions on the record, but

agreed, at King’s request, to issue a written opinion and order to facilitate his ability to appeal.

II. Procedural History In September 2023, King filed a complaint (“King I”) against various Philips-related entities and Polymer Technologies, Inc. and Polymer Technologies, Inc. – Molded Plastics Division. Philips filed a notice of removal to the United States District Court for the Northern District of Ohio on the basis of diversity jurisdiction. The JPML transferred the case to this court for pretrial proceedings as part of the Philips MDL and it was assigned Civil Case No. 23-2040. King filed an amended complaint in this court, in which he first named Cornerstone Medical Services-Midwest, LLC (“Cornerstone”) as a defendant. (Civ. No. 23-2040, ECF No. 21).

Cornerstone is the equipment supplier from whom King purchased a Philips Dreamstation CPAP device. King filed a motion to remand Civil Case No. 23-2040 to the state court, which was mooted by King’s subsequent voluntary dismissal of that case on June 14, 2024 (Civ. No. 23- 2040, ECF No. 22). On July 7, 2024, King initiated this case (“King II”) by filing another complaint in the Ohio state court. Philips and Cornerstone were named as defendants.1 Philips filed a notice of removal to the United States District Court for the Northern District of Ohio (Civil No. 24-1693,

1 On May 4, 2025, King filed (without leave a court) an amended complaint (Civ. No. 24-1693, ECF No. 31), to which defendants have not yet had an opportunity to respond. Although King named additional defendants, the averments in the amended complaint reflect that the only defendant which would implicate diversity of citizenship jurisdiction is Cornerstone. ECF No. 1). King filed a motion to remand and for sanctions (Civ. No. 24-1693, ECF No. 4). The JPML transferred the case to this court for pretrial proceedings as part of the Philips MDL and it was assigned Civil Case No. 24-1693. On March 21, 2025, King filed a renewed motion for remand at the Philips MDL main docket (Misc. No. 21-1230, ECF No. 3252).

III. Discussion King challenges subject-matter jurisdiction in the federal courts under 28 U.S.C. § 1332(a). King’s primary contention is that there is not complete diversity of citizenship between plaintiff and defendants. Specifically, King contends that Cornerstone and he are both citizens of Ohio. King also argues that Philips did not demonstrate the amount in controversy exceeds $75,000.

A. Timeliness As an initial matter, the motions are timely because they implicate the court’s subject-

matter jurisdiction. Federal courts have a nondelegable duty to sua sponte review actions to confirm that they have jurisdiction at all phases of the case. Louisville & Nashville R.R. Co. v. Mottley, 211 U.S. 149, 152 (1908); Buell v. Jarvis, No. CV 2025-0016, 2025 WL 857311, at *2 (D.V.I. Mar. 19, 2025) (“The Court has an independent and ongoing obligation to ensure that it has subject matter jurisdiction over an action, and to raise the issue sua sponte even when the parties fail to raise it.”) (citing Seneca Res. Corp. v. Township of Highland, 863 F.3d 245, 252 (3d Cir. 2017)). B. Diversity of citizenship Pursuant to 28 U.S.C. § 1332, federal courts may exercise diversity jurisdiction over cases that involve greater than $75,000 in controversy and are between citizens of different states. The statute requires “‘complete diversity between all plaintiffs and all defendants,’ even

though only minimal diversity is constitutionally required. This means that, unless there is some other basis for jurisdiction, ‘no plaintiff [may] be a citizen of the same state as any defendant.’” Lincoln Ben. Life Co. v. AEI Life, LLC, 800 F.3d 99, 104 (3d Cir. 2015) (quoting Lincoln Prop. Co. v. Roche, 546 U.S. 81, 89 (2005), and Zambelli Fireworks Mfg. Co. v. Wood, 592 F.3d 412, 419 (3d Cir. 2010)). The analysis to determine citizenship varies based upon the kind of entity involved. King does not contest that Cornerstone is a limited liability company (“LLC”). As explained in Okpor v. CBS News Broadcasting, No. 25-CV-0501, 2025 WL 1094254, at *4 (E.D. Pa. Apr. 11, 2025): An individual [such as King] is a citizen of the state where he is domiciled, meaning the state where he is physically present and intends to remain. See Washington v. Hovensa LLC, 652 F.3d 340, 344 (3d Cir. 2011). A corporation is a citizen of the state in which it was incorporated as well as where it has its principal place of business. See U.S.C. § 1332(c). In contrast, “the citizenship of an LLC [or other unincorporated entity] is determined by the citizenship of its members.” Zambelli, 592 F.3d at 420. “[W]here an LLC has, as one of its members, another LLC, the citizenship of unincorporated associations must be traced through however many layers of partners or members there may be to determine the citizenship of the LLC.” Id. (internal quotations omitted); see also Voorhees v. Tolia, 761 F. App'x 88, 91 (3d Cir. 2019) (per curiam) (“As for the entity defendants, they are limited liability companies and are deemed citizens of every state of which one of their members is a citizen.”).

Id. at *4. King points to documentation that Cornerstone registered as an Ohio LLC.
