Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF MARYLAND

NANJING 3H MEDICAL PRODUCTS * CO., LTD. * Plaintiff, * v. Civil Action No. RDB-24-2745 * KT HEALTH, LLC, * Defendant. * * * * * * * * * * * * * MEMORANDUM OPINION This action arises from the Parties’ dispute concerning seven patents for elastic therapeutic tape products. Plaintiff Nanjing 3H Medical Products Company, Ltd. (“Plaintiff” or “3H Medical”) filed a six-count complaint for declaratory relief, alleging that Defendant KT Health, LLC (“Defendant” or “KT Health”) inequitably obtained seven patents for kinesiology tape products invented by 3H Medical employees and used one of those patents to exclude 3H Medical from the online marketplace operated by Amazon.com, Inc. (“Amazon”). See generally (ECF No. 48). 3H Medical, which operates in China, allegedly allowed KT Health’s proprietor, Reed Quinn (“Mr. Quinn”), to commercialize its kinesiology tape products in the United States in 2008, but Mr. Quinn and KT Health patented the products in their own names between 2008 and 2022. (Id. ¶¶ 2-3, 45-51.) In June 2024, KT Health filed a notice of infringement with Amazon.com based on one of its patents, which then removed 3H Medical’s listings from its site. (Id. ¶¶ 131-32.) On September 23, 2024, 3H Medical initiated this action by filing in this Court a six- Count Complaint (ECF No. 4-1) against KT Health, seeking: (1) Declaratory Judgment of Invalidity of the KT Health Patents (Count I); (2) Declaratory Judgment of Unenforceability of the KT Health Patents (Count II); (3) Declaratory Judgment to Amend Inventorship of KT Health’s Patents Under 35 U.S.C. § 256 (Count III); (4) Declaratory Judgment of Intentional

Interference with Contractual Relations (Count IV); (5) Declaratory Judgment of Intentional Interference with Economic Relations (Count V); and (6) Declaratory Judgment of Unfair Competition (Count VI). (ECF No. 4-1; Am. Compl. ECF No. 48 (same)). 3H Medical’s complaint challenges the validity and enforceability of seven patents—four design patents and three utility patents—that KT Health has obtained for kinesiology tape products since 2008. Presently pending before this Court is Plaintiff KT Health’s Motion to Transfer the

Case to the District of Utah pursuant to 28 U.S.C. § 1404(a) (ECF No. 73) (the “Motion”), as well as four other motions filed by the Parties, including 3H Medical’s two motions to dismiss (ECF Nos. 56-57). In the interest of efficiency for the Parties and the Court, the Court considers KT Health’s Motion to transfer before considering the new motions to dismiss and other motions. The Parties’ submissions on this Motion have been reviewed, and no hearing is necessary. See Local Rule 105.6 (D. Md. 2025).

For the reasons that follow, Plaintiff’s Motion to Transfer the Case to the District of Utah (ECF No. 73) is GRANTED. The Court TRANSFERS this matter to the United States District Court for the District of Utah. Other pending motions (ECF Nos. 56, 57, 60, and 63) are therefore DENIED AS MOOT WITHOUT PREJUDICE TO RENEWAL by refiling in the District of Utah.1

1 Given the Court’s decision granting the motion to transfer, pending motions (ECF Nos. 56, 57, 60, and 63) are denied as moot without prejudice to renew so that the motions may be refiled, upon transfer, in the District of Utah. See 15 Wright & Miller’s Fed. Prac. & Proc. Civ. § 3846 (4th ed. BACKGROUND

When Plaintiff filed this action, Defendant KT Health, LLC, was organized under the laws of Delaware with a principal place of business in American Fork, Utah. (Compl. ¶ 5; Am. Compl. ¶ 5; ECF No. 73-1 ¶ 1). KT Health maintained its principal place of business in Utah for over ten years until it was acquired in 2025. (ECF No. 73 at 1-2; ECF No. 78-1 (reporting acquisition of Utah-based KT Health by Bridges Consumer Healthcare LLC on January 16, 2025)). KT Health’s principal officers and employees, and the named inventor listed on KT

Health’s design patents, Reed Quinn, have resided in Utah. (ECF No. 73 at 6). Plaintiff 3H Medical is a Chinese corporation with a principal place of business in China. (Am. Compl. ¶ 4).2 The Maryland Action

Plaintiff filed this action after KT Health filed a notice of infringement with Amazon, alleging that 3H Medical’s kinesiology tape products infringed KT Health’s design patent U.S. Patent No. D962,344 (“the ‘344 Patent”). (Am. Compl. ¶¶ 1, 131). As a result of this notice, 3H Medical’s product listings were removed from Amazon.com, (id. ¶¶ 132-33) and, due to the risk of similar notices based on other patents held by KT Health, 3H Medical removed

2018) (recognizing that when a motion to transfer pursuant to 28 U.S.C. § 1404(a) is granted and the papers are lodged with the transferee court, “the transferor court . . . loses jurisdiction over the case and may not proceed further with regard to it”); see, e.g., Estate of Nelson v. MillerKnoll, Inc., No. 21-CV- 7811, 2023 WL 3159678, at *6 (S.D.N.Y. Apr. 28, 2023) (granting transfer and denying pending motion to dismiss as moot with leave to renew in transferee court); Kurtz v. Intelius, Inc., No. 2:11– CV–01009, 2011 WL 4048645, *3 (E.D. Cal. 2011) (determining, after granting motion for transfer, that “all other pending motions will not be considered by this Court and may be considered in the [transferee court]”).

2 In this action, the one counsel of record for Plaintiff 3H Medical is based in Hawaii. KT Health is represented by three attorneys based in Utah and one attorney based in Washington, D.C. additional product listings. (Am. Compl. ¶¶ 1, 138). 3H Medical removed all physical kinesiology tape inventory from Amazon warehouses nationwide, including from Amazon Warehouse BW12 in Baltimore, Maryland. (Am. Compl. ¶¶ 1, 9).

Plaintiff’s Amended Complaint seeks a declaration that it has not infringed, and is not infringing, any valid patent rights of KT Health in the ‘344 Patent, or other KT Health related patents, due to 3H Medical’s marketing and sale of its kinesiology tape products in the United States. (Am. Compl. ¶ 3). Specifically, Plaintiff seeks a declaratory judgment regarding the

following KT Health patents: • U.S. Design Patent No. D962,344 (the “‘344 patent”); • U.S. Design Patent No. D947,944 (the “‘944 patent”);

• U.S. Design Patent No. D988,400 (the “‘400 patent”); • U.S. Design Patent No. D1,011,420 (the “‘420 patent”); • U.S. Patent No. 9,308,115 (the “‘115 patent”); • U.S. Patent No. 10,617,571 (the “‘571 patent”); and

• U.S. Patent No. 10,973,697 (the “‘697 patent”). (Am. Compl. ¶¶ 14-34).

On November 15, 2024, 3H Medical filed a motion for a preliminary injunction. (ECF No. 7). On November 20, 2024, KT Health moved to dismiss 3H Medical’s Complaint pursuant to Federal Rule of Civil Procedure 12(b)(6). After a hearing during which the Court heard oral argument from the Parties, the Court issued a memorandum opinion and order. (ECF No. 41). The Court granted KT Health’s motion to dismiss in part, dismissing Count II without prejudice, and the Court denied 3H Medical’s motion for a preliminary injunction. (ECF No. 41 at 2).

Thereafter, 3H Medical filed an Amended Complaint (ECF No. 48) to which KT Health filed an answer and counterclaim for eleven counts of infringement on October 2, 2025. (ECF No. 45). KT Health’s counterclaim for infringement is based on the ‘944, ‘400, and ’420 patents, as well as the following additional utility patents:
