OPINION AND ORDER Pending before the Court is Plaintiff Middleton Mixology’s Motion for Preliminary Injunction against Defendant Shenzhan Huazhi Technology Co., Ltd d/b/a HzSane (“HzSane”) (Dkt. 37). In November 2024, Middleton filed suit against HzSane and twenty other Chinese e- commerce vendors for allegedly infringing on their ’769 Patent by selling products in the United States with similar design features to the Modular Smoker. (Dkt. 1 ¶¶ 15–23). Following the Court’s issuance of a Temporary Restraining Order, (Dkt. 15), Middleton moved for a preliminary injunction. For the following reasons, the Court denies Middleton’s Motion [37]. BACKGROUND

I. Procedural Posture

On November 30, 2024, Middleton filed a Complaint asserting patent infringement under 28 U.S.C. § 281 against the Defendant class and moved for a TRO. (See Dkt. 1 ¶¶ 24–30; Dkt. 5). On December 10, 2024, the Court issued a TRO, which prohibited the future sales and marketing of the allegedly infringing product. (Dkt. 15). On January 2, 2025, Middleton moved to convert the TRO into a preliminary injunction. (Dkt. 37). II. Alleged Infringement

Both Middleton and HzSane sell “smokers”—devices that infuse a smoky flavor into food and beverages. (Dkt. 1 ¶¶ 8–14). United States Patent No. 11,871,769 (’769 Patent), which was issued on January 16, 2024, (Dkt. 7 ¶ 4), gives Middleton exclusive rights to make, distribute, and sell its smoker design, the Modular Smoker, in the United States. (Id.). Middleton alleges that HzSane sells smokers in the United States that infringe on the design specifications protected by Middleton’s ’796 Patent. (Dkt. 1 ¶¶ 15–23). The accused product is a smoker for infusing smoke into flavor into food or beverages. (Dkt. 7 at 7). Middleton claims that HzSane’s smoker infringes at least on Claim 8 of the ’769 Patent. (Dkt. 7 ¶ 6). Claim 8 states: A smoker for infusing smoke into flavor and/or taste of a beverage or food, the smoker comprising: a body member having a through bore extending from a first end of the body member to an opposite second end of the body member in a first direction; and an insert configured to permit smoke to pass therethough; wherein the through bore has opposing open ends along a longitudinal axis, wherein the through bore is configured to receive the insert via the first end and to retain the insert at a position between the first end and the second end, wherein the through bore and the insert are configured to define a chamber for receiving a combustible material between the insert and the first end, wherein the through bore is configured to permit a flow of smoke from the combustible material out the through bore at the second end of the body member, and wherein the second end of the body member is sized and configured to rest on a rim of a container to block the flow of air from the container where a surface of the second end of the body member contacts the rim.

(Dkt. 70-3, Middleton’s Exhibit 3). On July 2, 2025, the Court held an evidentiary hearing to assess HzSane’s expert witness, Randy Clarksean. (Dkt. 108). LEGAL STANDARD

A defendant is liable for patent infringement if it, “without authority makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States and patent invention during the term of the patent thereof.” 35 U.S.C. § 271(a). The Patent Act authorizes courts to grant injunctions to prevent violations of patent rights. 35 U.S.C. § 283. To obtain a preliminary injunction, the moving party must show: “(1) a reasonable likelihood of success on the merits; (2) irreparable harm if an injunction is not granted; (3) a balance of hardships tipping in its favor; and (4) the injunction's favorable impact on the public interest.” Amazon.com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1350 (Fed. Cir. 2001). On likelihood of success, Middleton must show that (1) it can likely prove that HzSane is infringing the ’769 Patent and (2) that the ’769 Patent will likely withstand HzSane’s challenge to its validity. See Titan Tire Corp. v. Case New Holland, Inc., 566 F.3d 1372, 1376 (Fed. Cir. 2009). Moreover, “a preliminary injunction is an extraordinary remedy never awarded as of right.” Wind Tower Trade Coal. v. United States, 741 F.3d 89, 95 (Fed. Cir. 2014) (quoting Winter v. Nat. Res.

Def. Council, Inc., 555 U.S. 7, 24 (2008)). DISCUSSION

I. Likelihood of Success on the Merits

To infringe on a patent, “each and every element of the claim must be practiced by the infringer.” Sonrai Sys., LLC v. AMCS Grp. Inc., 2017 WL 4281122, at *3 (N.D. Ill. Sept. 27, 2017) (citing Limelight Networks, Inc. v. Akamai Techs., Inc., 572 U.S. 915 (2014)). The analysis involves two steps: (1) “the court determines the scope and meaning of the asserted claims”; and (2) “the properly construed claims are compared to the allegedly infringing device.” Edge Sys. LLC v. Aguila, 635 F. App’x 897, 902 (Fed. Cir. 2015) (quoting Mas–Hamilton Grp. v. LaGard, Inc., 156 F.3d 1206, 1211 (Fed. Cir. 1998) (citations omitted). To determine the meaning of the asserted claims, “the court establishes the scope and limits of the claim, interprets any technical or other terms whose meaning is at issue, and thereby defines

the claim with greater precision than had the patentee.” Pall Corp. v. Hemasure Inc., 181 F.3d 1305, 1308 (Fed. Cir. 1999). Furthermore, a court should not issue the preliminary injunction “if an alleged infringer raises a substantial question regarding either infringement or validity, i.e., the alleged infringer asserts an infringement or invalidity defense that the patentee has not shown lacks substantial merit.” AstraZeneca LP v. Apotex, Inc., 633 F.3d 1042, 1050 (Fed. Cir. 2010) Middleton only asserts that HzSane infringed on Patent ’769’s Claim 8; therefore, HzSane need only show that its smoker device does not infringe Claim 8 of the ’769 Patent to prevail. a. “Through Bore”
