Jun 2, 2026MAILED Patent report to Patent Trademark Office, Alexandria VA (bi, ) (Entered: 06/02/2026)PACER Document
Jun 2, 2026MINUTE entry before the Honorable Lindsay C. Jenkins: Upon review of the complaint, the court questions whether Plaintiff has sufficiently alleged that the court can exercise personal jurisdiction over Defendants Wencan Zhu and Nanchang White Technology Co. Ltd.. To adequately plead personal jurisdiction, Plaintiff must sufficiently allege that Defendants actually sold the allegedly infringing product to a customer in Illinois. See Liu v. Monthly, 170 F.4th 1090 (7th Cir. 2026) (citing Curry v. Revolution Lab'ys, LLC, 949 F.3d 385, 400 (7th Cir. 2020). The complaint here alleges only that Defendants "structured its business activities so as to target consumers in the United States, including Illinois," and that Defendants "targeted sales to Illinois residents by manufacturing, importing, distributing, advertising, offering for sale, and selling the accused products, which were offered for sale and sold through the Amazon.com" and elsewhere. [Dkt. 1, para. 3.] Those allegations are conclusory, and Plaintiff did not provide proof of actual sales in this district. See id. (remanding with instructions to dismiss for lack of personal jurisdiction because plaintiff had not provided screenshot evidence of actual sales in Illinois). By June 8, 2026, Plaintiff must file either a memorandum explaining why personal jurisdiction is proper, or an amended complaint setting forth with more than conclusory statements the alleged infringing activity and grounds for personal jurisdiction. Failure to comply by June 8, 2026 will result in the current complaint being dismissed without prejudice and this case being closed. Lastly, the court notes Plaintiff's complaint affirmatively alleges that both Defendants reside or exist in China, see paras. 6 and 7, so in light of this representation, the court draws Plaintiff's attention to the Seventh Circuit's recent holding in Kangol LLC v. Hangzhou Chuanyue Silk Import & Export Co., Ltd., Appeal No. 25-2205 (7th Cir. May 29, 2026) that the Hague Convention prohibits email service to an entity in China. Mailed notice.
