What was filed
Xinxing Lin v. Generic S and the Individual or Entity Operating Generic S, No. 1:26-cv-11939 (N.D. Ill., Eastern Division), was filed September 29, 2026. Lin alleges, on information and belief, that the defendant is a foreign individual or entity, operating from China or another foreign jurisdiction, that runs an Amazon storefront. The clerk's assignment entry assigns the case to Judge Charles P. Kocoras.
The mark
USPTO records show U.S. Reg. No. 7,937,911 for TRIVOLUSIA, registered September 9, 2025, to Xinxing Lin for Class 28 goods including sport balls, dolls, and plush toys. The complaint alleges that Lin has used the mark for sports and recreational products, including footbags, since at least 2024.
What the complaint alleges
The complaint alleges that the defendant's Amazon listing used Trivolusia as the brand name in the title of a six-pack footbag set, a title it says is identical or nearly identical to the title of Lin's own listing, and that Lin never licensed or authorized that use.
The counts and relief
Count I alleges trademark infringement and counterfeiting under 15 U.S.C. § 1114. Count II alleges false designation of origin under 15 U.S.C. § 1125(a). Lin seeks damages, injunctive relief, and other Lanham Act remedies.
