Quanzhou Jiuci Sues Schedule A Sellers on a Laptop Bag Design Patent.

The complaint

The case is Quanzhou Jiuci Trading Co., Ltd. v. The Partnerships, Unincorporated Associations Identified on Schedule A, No. 1:26-cv-26834 (S.D. Fla.), a design-patent infringement complaint filed September 29, 2026. The plaintiff is Quanzhou Jiuci Trading Co., Ltd., which the complaint describes as a limited liability company organized under the laws of the People's Republic of China, based in Fujian, China, and engaged in the design, distribution, licensing, and sale of laptop bags. Schedule A lists 40 defendants by Amazon seller alias and storefront link. The complaint alleges, on information and belief, that the defendants reside and operate in China and run e-commerce stores under the Schedule A seller aliases, through accounts on Amazon and other marketplace platforms.

Jurisdiction and venue

The complaint pleads subject matter jurisdiction under 28 U.S.C. 1331 and 1338(a). It alleges personal jurisdiction because each defendant targets consumers in the United States, including Florida, through interactive e-commerce stores, and venue under 28 U.S.C. 1391 and 1400 because the defendants have committed patent infringement and do substantial business in the district.

The patent and claims

The complaint asserts U.S. Patent D1,057,416, titled Laptop Bag, which issued January 14, 2025. Its single claim reads: "The ornamental design for a laptop bag, as shown and described." The complaint alleges the plaintiff owns all right, title, and interest in the patent. It sets the patent's figures beside images of an accused product offered in one of the defendants' stores and alleges that, to an ordinary observer, the accused design is substantially the same as the claimed design.

What the lawsuit is about

The complaint alleges the defendants, without authorization, make, use, offer for sale, sell, and import products embodying the claimed design, sell them through stores operating under the Schedule A seller aliases while concealing their identities, and offer the same infringing product, with shared product images, listing text, and storefront features indicating a common source. It alleges the stores offer shipping to Florida and accept payment in U.S. dollars, and, on information and belief, that the defendants knowingly and willfully infringe, that the products come from a common manufacturer or supplier, and that the defendants have sold and shipped infringing products to consumers in Florida.

The counts and relief sought

Count I alleges design-patent infringement under 35 U.S.C. 271(a) and pleads entitlement to an injunction under 35 U.S.C. 283. The prayer asks for temporary, preliminary, and permanent injunctions; an order that online marketplaces such as Amazon disable advertisements associated with the defendants' sales of the accused products; damages of no less than a reasonable royalty under 35 U.S.C. 284, increased three times; the defendants' profits under 35 U.S.C. 289; reasonable attorneys' fees and costs; and other relief.

What to watch next

Watch for orders on preliminary relief and service, defendant appearances, and dismissals of individual sellers. The case can end at any time, including by settlement or voluntary dismissal.
