SHENZHEN JISU TECHNOLOGY CO., LTD. v. 3 THE ENTITIES AND INDIVIDUALS IDENTIFIED IN ANNEX A

Dissenting opinion filed by Circuit Judge STOLL. HUGHES, Circuit Judge. Shenzhen Jisu Technology Co., Ltd. appeals a decision of the United States District Court for the Northern Dis- trict of Illinois that (1) dissolved an earlier-issued prelimi- nary injunction against defendant-appellee Zhouty, and (2) denied a temporary restraining order against newly added defendants. We affirm. I Appellant Shenzhen Jisu Technology Co., Ltd. (Shen- zhen) owns U.S. Design Patent No. D886,982, which claims a design for a foldable fan. In April 2024, Shenzhen as- serted the ’982 patent against a group of entities identified in an appendix to its complaint in what is known as a Schedule A case. Defendants are all e-commerce vendors accused of selling infringing products through online store- fronts like Amazon and Temu. As is standard in Sched- ule A cases, Shenzhen immediately moved for an ex parte temporary restraining order (TRO), seeking to enjoin all defendants from selling the accused products. The TRO was granted, and Shenzhen subsequently moved to convert it into a preliminary injunction (PI). Unlike most Schedule A cases, where defendants typi- cally do not participate in the proceedings, several defend- ants appeared to oppose the PI. As relevant here, defendant-appellee Zhouty appeared, arguing that there were “readily-apparent and substantial differences” be- tween its accused product and the ’982 patent’s claimed de- sign. J.A. 1475. Given those differences, Zhouty argued Shenzhen could not prove it was likely to succeed on the merits of its infringement claim, and therefore Shenzhen was not entitled to a PI. Cf. Winter v. Nat. Res. Def. Coun- cil, Inc., 555 U.S. 7, 20 (2008) (“A plaintiff seeking a pre- liminary injunction must establish that he is likely to succeed on the merits . . . .”). The district court disagreed, Case: 25-1617 Document: 58 Page: 4 Filed: 07/22/2026

finding that the “overall ornamental visual impression” of Zhouty’s accused product was “quite similar” to the design claimed in the ’982 patent. Shenzhen Jisu Tech. Co. v. En- tities & Individuals Identified in Annex A, No. 24 C 2948, 2024 WL 5440040, at *2 (N.D. Ill. Nov. 13, 2024) (Shen- zhen I). As a result, the district court concluded Shenzhen had demonstrated a reasonable likelihood of success on the merits of its infringement claim and issued the requested PI. Id. at *2–3. After Zhouty’s PI briefing was complete, the United States Patent and Trademark Office issued U.S. Patent No. D1,046,104 to a third party. The ’104 patent also claims a design for a foldable fan, and it lists the ’982 pa- tent as a prior art reference. See U.S. Patent No. D1,046,104. Citing the issuance of the ’104 patent as new evidence disfavoring preliminary injunctive relief, Zhouty requested that the district court reconsider its decision granting Shenzhen’s PI. Zhouty argued that because novelty is a re- quirement for patentability, the patent examiner must have concluded that the ’982 patent’s design did not antic- ipate the ’104 patent’s design—otherwise, the ’104 patent would not have issued. And, because the test for design pa- tent infringement and the test for anticipation are identi- cal, the conclusion that the ’982 patent does not anticipate the ’104 patent would suggest that products practicing the ’104 patent’s design do not infringe the ’982 patent. To- gether with the representation that the ’104 patent pro- tects the exact design of Zhouty’s accused product, Zhouty argued that the ’104 patent’s issuance suggested there is some material and patentable difference between the de- sign of its accused product and the design protected by the ’982 patent. Zhouty suggested that this undermined the likelihood Shenzhen would succeed in its infringement ac- tion, which in turn undercut its entitlement to a PI. Shen- zhen disagreed, and the district court ultimately denied reconsideration. Case: 25-1617 Document: 58 Page: 5 Filed: 07/22/2026

SHENZHEN JISU TECHNOLOGY CO., LTD. v. 5 THE ENTITIES AND INDIVIDUALS IDENTIFIED IN ANNEX A

A month later, Shenzhen added five new defendants to its suit, including the owner of the ’104 patent (New De- fendants), and moved for an ex parte TRO against those New Defendants. Despite its ex parte nature, the New De- fendants appeared to oppose the TRO, advancing the same argument that Zhouty made on reconsideration regarding the impact of the ’104 patent’s issuance on the likelihood of success of Shenzhen’s infringement claim. Shenzhen re- plied in support of its request for injunctive relief, empha- sizing the district court had already rejected this argument and suggesting it should do so again. 1 On February 28, 2025, the district court denied Shen- zhen’s request for injunctive relief as to the New Defend- ants and simultaneously dissolved the earlier-issued PI against Zhouty. Shenzhen Jisu Tech. Co. v. Entities & In- dividuals Identified in Annex A, No. 24 C 2948, 2025 WL 879994, at *1 (N.D. Ill. Feb. 28, 2025) (Shenzhen II). The district court found it compelling that new facts were un- covered since it denied reconsideration that suggested Zhouty and the New Defendants were all authorized to sell folding fans embodying the design claimed in the ’104 pa- tent. Id. at *2.
