Opinion

UNITED STATES DISTRICT COURT NORTHERN DISTRICT OF ILLINOIS EASTERN DIVISION

SHENZHEN ZHIFU NETWORK TECHNOLOGY CO., LTD, ET AL.,

Plaintiffs, No. 24 CV 11277

v. Judge April M. Perry

CORE HOME FITNESS, L.L.C.,

Defendant.

MEMORANDUM OPINION AND ORDER Before this Court is Defendant’s motion to dismiss the complaint for lack of personal jurisdiction, improper venue, insufficient process, and insufficient service of process. Doc. 15. As is set forth in more detail below, the Court finds that Plaintiffs have not properly established that this Court can exercise personal jurisdiction over Defendant or demonstrated that the Northern District of Illinois is the appropriate venue for this case. Therefore, the complaint is dismissed without prejudice. Plaintiffs are free to file this suit in the Northern District of Ohio, where not only will their personal jurisdiction and venue problems be solved, but they also will presumably be able to rectify any alleged issues with the service of process. BACKGROUND Plaintiffs are China-based companies that own e-commerce stores which sold adjustable dumbbells. Doc. 1 ¶ 8. Defendant also owns an e-commerce store selling adjustable dumbbells, and furthermore holds U.S. Patent No. 7,614,983 B1 for adjustable dumbbells (“the 983 patent”). Id. ¶¶ 10-11, 15. According to the complaint, Defendant filed notices with various online retailers indicating that Plaintiffs’ dumbbells may be infringing the 983 patent. Id. ¶ 13. As a result, Plaintiffs’ dumbbells have been removed from at least one online storefront and Plaintiffs contend that they have “suffered significant financial losses.” Id. ¶ 16. Plaintiffs filed the instant complaint requesting a declaratory judgment of non-infringement of the 983 patent (Count One), declaratory judgment of invalidity of the 983 patent (Count Two), and damages caused by fraudulent reports of patent infringement (Count Three). Id. at 13, 27, 28. ANALYSIS A. Personal Jurisdiction The Court begins with Defendant’s argument that the complaint should be dismissed for lack of personal jurisdiction. A plaintiff has the burden of establishing personal jurisdiction once it is challenged in a motion to dismiss. Purdue Rsch. Found. v. Sanofi-Synthelabo, S.A., 338 F.3d 773, 782 (7th Cir. 2003). In ruling on the motion, courts may consider facts in affidavits submitted by the parties, but the plaintiff is entitled to have any disputed facts resolved in its favor. Id. For a fact to be truly disputed, once a defendant “has submitted affidavits or other evidence in opposition to the exercise of jurisdiction, the plaintiff must go beyond the pleadings and submit affirmative evidence supporting the exercise of jurisdiction.” Id. at 783. The cause of action in this case arises under federal law. Doc. 1 ¶ 1. “In a case involving federal question jurisdiction, a federal court has personal jurisdiction over the defendant if either federal law or the law of the state in which the court sits authorizes service of process to that defendant.” NBA Properties, Inc. v. HANWJH, 46 F.4th 614, 620 (7th Cir. 2022) (internal quotations removed). Here, there is no federal law establishing personal jurisdiction that would apply. Therefore, the question becomes whether Illinois law authorizes the exercise of personal jurisdiction over Defendant. The Illinois long-arm statute permits personal jurisdiction consistent with the Illinois Constitution and U.S. Constitution. 735 ILCS 5/2-209(c). Under the Due Process Clause of the U.S. Constitution, an out-of-state defendant is not subject to suit in a forum unless it “purposefully directed” its activities to that state and the litigation relates to those activities. Burger King Corp. v. Rudzewicz, 471 U.S. 462, 472 (1985). Moreover, the defendant must “have certain minimum contacts with [the forum] such that the maintenance of the suit does not offend traditional notions of fair play and substantial justice.” Int’l Shoe Co. v. Washington, 326 U.S. 310, 316 (1945).1 In this case, it is undisputed that Defendant is incorporated under the laws of Nevada and has its principal place of business in Ohio. Doc. 1 ¶ 10-11; Doc. 16-1 ¶ 4. Defendant has no physical presence in Illinois. Doc. 16-1 ¶ 4. The sole basis for personal jurisdiction asserted by Plaintiff is that “Defendant directly targets business activities toward consumers in the State of Illinois by setting up and operating fully interactive e-commerce stores … that target Illinois consumers, offers shipping to Illinois, accepts payment in U.S. dollar [sic] and, on information and belief, has sold products to residents of Illinois.” Doc. 1 ¶ 7. The problem with Plaintiffs’ personal jurisdiction argument is simple: Even if Plaintiffs’ alleged facts are true, none of Defendant’s contacts with Illinois gave rise to this litigation. Evidence of a defendant’s online sales in a state can confer personal jurisdiction when the cause of action arises from defendant’s online sales; online sales do not confer personal jurisdiction when the cause of action arises from some other alleged misconduct. Compare Matlin v. Spin Master Corp., 921 F.3d 701, 707 (7th Cir. 2019) (dismissing complaint for lack of personal jurisdiction where there was only evidence of a single online sale to Illinois and the suit was an intellectual property dispute that was about

1 Plaintiffs argue only for specific jurisdiction over Defendant, they do not allege that the Court has general jurisdiction. Doc. 19 at 4. Therefore, the Court proceeds with the analysis based solely upon specific jurisdiction. “an out-of-state defendant’s refusal to pay royalties on sales made nationwide”), and Advanced Tactical Ordnance Sys., LLC v. Real Action Paintball, Inc., 751 F.3d 796, 801 (7th Cir. 2014) (“Not only did [plaintiff] fail to link the few sales to [defendant’s] litigation-specific activity, but even if it did, it is unlikely that those few sales alone, without some evidence linking them to the allegedly tortious activity, would make jurisdiction proper.”), with NBA Properties, Inc. v. HANWJH, 46 F.4th 614 (7th Cir. 2022) (defendant’s sales of infringing products to Illinois customers found to support personal jurisdiction in an infringement case), and Curry v. Revolution Laboratories, LLC, 949 F.3d 385, (7th Cir. 2020) (same), and uBID, Inc. v. The GoDaddy Group, Inc., 623 F.3d 421, 431 (7th Cir. 2010) (“the contacts alleged in [plaintiff’s complaint] and the wrongs alleged in [plaintiff’s] complaint are so intimately related that [defendant] cannot reasonably have been surprised to find itself sued in Illinois”). Here, the cause of action does not arise from Defendant’s online sales but, as discussed below, from some other alleged misconduct. In this case, the alleged misconduct is Defendant trying to enforce patents that are either invalid or which Plaintiffs’ products do not infringe.
