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 In this action for declaratory relief, Plaintiff Nanjing 3H Medical Products Company, Ltd. (“Plaintiff” or “3H Medical”) alleges 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. 4-1). 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.) In June 2024, KT Health used one of its patents to file a notice of infringement with Amazon, which removed 3H Medical’s listings from its site. (Id. ¶ 53.) On July 10, 2024, 3H Medical filed an ex parte reexamination1 request with the United States Patent and Trademark

1 The USPTO may grant ex parte reexamination where a party asserts that there exists a “substantial new question of patentability.” In re Vinvint, Inc., 14 F.4th 1342, 1346 (Fed. Cir. 2021) (quoting 35 U.S.C. § 303(a)). During such proceedings, the patent does not receive a presumption of validity, and the patentee must prove validity by a preponderance of the evidence. In re Swanson, 540 F.3d 1368, 1377–78 (Fed. Cir. 2008). Office (“USPTO”), in which it sought cancellation of the patent undergirding KT Health’s complaint to Amazon. (ECF No. 4-1 ¶ 58.) USPTO granted ex parte reexamination, and that proceeding remains pending. See (ECF No. 35-1).

On September 23, 2025, 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.) Unlike the ex parte reexamination, this action 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 are two motions filed by the parties: (1) Plaintiff’s Motion for Preliminary Injunction (ECF No. 7); and (2) Defendant’s Motion to Dismiss (ECF

No. 11). The Court has reviewed the parties’ filings and, on August 20, 2025, heard oral argument from the parties as to both motions. For the reasons set forth on the record and elaborated below, Defendant’s Motion to Dismiss (ECF No. 11) is GRANTED IN PART an DENIED IN PART. Specifically, Defendant’s Motion (ECF No. 11) is DENIED as to Counts I, III, IV, V, and VI, and GRANTED as to Count II, which is DISMISSED WITHOUT PREJUDICE. Additionally, as set forth on the record and further explained

below, Plaintiff’s Motion for Preliminary Injunction is DENIED. BACKGROUND In ruling on a motion to dismiss, this Court “accept[s] as true all well-pleaded facts in a complaint and construe[s] them in the light most favorable to the plaintiff.” Wikimedia Found.

v. Nat’l Sec. Agency, 857 F.3d 193, 208 (4th Cir. 2017) (citing SD3, LLC v. Black & Decker (U.S.) Inc., 801 F.3d 412, 422 (4th Cir. 2015)). Except where otherwise indicated, the following facts are derived from Plaintiff’s Complaint (ECF No. 4-1) and accepted as true for the purpose of Defendant’s Motion to Dismiss (ECF No. 11). The parties offered general background statements at the motions hearing, and the Court provides only a brief factual summary below. This litigation relates to the therapeutic tape known generically as kinesiology

therapeutic tape (“kinesiology tape”), which is used to treat pain and disability from physical ailments, particularly athletic injuries.2 (ECF No. 4-1 ¶ 14.) 3H Medical alleges that it has innovated, developed, manufactured, commercialized, and patented kinesiology tape since before 2008. (Id. ¶ 15.) It manufactures kinesiology tape for third-party sellers and sells its own branded products via online platforms such as Amazon.com (“Amazon”). (Id.) Before 2008, it manufactured kinesiology tape in the form of rolls of tape; rectangles of various

dimensions with rounded corners; and rectangles of various dimensions with rounded corners and pre-cut centerlines down the strip of tape. (Id. ¶¶ 17, 18.) It sold such products under brands like Easytape™ and Spidertech. (Id. ¶ 18.) According to 3H Medical, the parties’ relationship began in 2008, when KT Health’s founder, Reed Quinn (“Mr. Quinn”), requested that 3H Medical manufacture kinesiology tape

2 Common names for kinesiology tape include “elastic therapeutic tape,” “kinesio tape,” “k-tape,” and “KT.” (ECF No. 4-1 ¶ 14.) For clarity, this Memorandum Opinion refers to the product as “kinesiology tape.” for him. (Id. ¶ 19.) 3H Medical alleges that Mr. Quinn contacted it to request rounded corner, rectangular tape strips sold in roll configurations but customized with “KT Health” logos and custom glue patterns. (Id.) Mr. Quinn informed 3H Medical that he intended to re-sell this

product to American retailers. (Id.) Accordingly, he worked with 3H Medical to develop samples, which he publicly displayed and distributed to physical trainers on November 11 or November 13, 2008. (Id. ¶¶ 20–21.) Mr. Quinn then ceased communication with 3H Medical, and on November 26, 2008, KT Health—then called Lumos, Inc.—sought patent protection for (1) the kinesiology tape rolls that 3H Medical allegedly designed; and (2) the method of manufacture of such tape. (Id. ¶¶ 23–24.) On or about January 20, 2009, KT Health published

its website, which allegedly promoted the products produced by 3H Medical. (Id. ¶ 22.) 3H Medical alleges that between 2008 and 2022, Mr. Quinn was named as sole inventor in at least fifteen utility and design patent applications and KT Health was named as owner in such patents. (Id. ¶ 24; ECF No. 7 at 10.) The first patent KT Health and Mr. Quinn obtained was an informal provisional patent—filed as U.S. Provisional Patent Application Number 61/200,400 (‘400 Application) on November 26, 2008—that is not challenged in this action.

(ECF No. 4-1 ¶ 48.) As relevant to the instant matter, 3H Medical challenges the validity of seven subsequent patents: four design patents and three utility patents.3 The challenged utility

3 “A design patent protects a ‘new, original and ornamental design for an article of manufacture.’” LKQ Corp. v. GM Glob. Tech. Operations, LLC, 102 F.4th 1280, 1291 (Fed. Cir. 2024) (quoting 35 U.S.C. § 171(a)). A utility patent protects the “function” of a product. See 35 U.S.C. § 171; USPTO, USPTO.GOV, Manual of Patent Examining Procedure § 1502.01.
