Shenzhen Chitado Sues X Future and Isinwheel and iScooter Sellers in Sherman Over Seated Scooter Basket Patents.

The case

The case is Shenzhen Chitado Technology Co., Ltd. v. X Future LLC, No. 4:26-cv-01568 (E.D. Tex., Sherman Division), assigned to Judge Amos L. Mazzant III. The complaint is signed by Roumin Xie and also lists Mingbo Ye and Jia Li of Veritas Light Law Group in Newport Beach, California.

The complaint describes Shenzhen Chitado as a Chinese limited liability company based in Shenzhen that sells electric riding devices, including under its GYROOR brand. It describes X Future LLC as a Texas limited liability company based in Plano, Texas, and alleges, on information and belief, that X Future LLC operates isinwheel.com and that X Future Inc. is a California corporation that operates iscooter.com and lists a Plano mailing address. Five defendants are Amazon storefront operators: Shenzhen Lvyushu Technology Co., Ltd., doing business as isinwheel center; Shenzhenshiyongyangfengkejiyouxianzerengongsi, doing business as isinwheel-Shop; Shenzhenwushengshangmaoyouxiangongsi, doing business as iScooter Shop; Dong Guan Shi Lin Hui Mao Yi You Xian Gong Si, doing business as iScooter Center; and Shenzhenshiyuntengwanwukejiyouxiangongsi, doing business as iScooter Pro Shop. The last defendant is Shenzhen Xincheng Times Technology Co., Ltd., which the complaint says FCC filings, product manuals and Amazon product information identify as the manufacturer of the accused products.

The patents and the asserted claims

U.S. Patent No. 12,649,534, "Electric Riding Device," issued June 9, 2026. The complaint asserts claims 1 to 4 and 6 to 15 against the H7 products and claims 6, 7, 9 to 12, 14 and 15 against the DX5 products, and quotes claim 6 as representative. Claim 6 covers an electric riding device with a frame body defining a substantially flat support plate, front and rear wheels, a handlebar assembly, a seat, a power device, and an open-top storage basket removably coupled to the upper surface of the support plate, with left and right sidewalls that rise from near the plate's side edges, and left and right footrests near the front sides of the support plate.

U.S. Patent No. 12,595,012, also titled "Electric Riding Device," issued April 7, 2026, and is asserted through claim 7 against all four products. Claim 7 covers an electric riding device whose frame body has a substantially flat base portion with raised front and rear portions supporting the head tube and the seat, a removable storage basket whose contact surface sits in substantially horizontal contact with the base portion, and left and right footrests mounted nearer the front ends of the base portion than the rear. The complaint alleges that Shenzhen Chitado is the assignee and owner of all substantial rights in both patents.

The counts

Counts I and II allege infringement of the '534 patent by the H7 defendants and the DX5 defendants, and Counts III and IV allege the same for the '012 patent. Each count alleges direct infringement under 35 U.S.C. 271(a). The complaint alleges that Shenzhen Xincheng Times Technology induced infringement under 35 U.S.C. 271(b), and, on information and belief, that it also directly infringed. It pleads that the filing of the action is notice of infringement under 35 U.S.C. 287(a).

The relief sought

Shenzhen Chitado asks for a judgment of infringement; a preliminary and permanent injunction against making, using, selling, offering or importing the accused products, with provisions directed at the defendants' online storefronts; an order, to the extent Federal Rule of Civil Procedure 65(d)(2) authorizes it, directed to those in active concert with the defendants who have notice of the injunction, including online marketplaces, to disable infringing listings and storefronts; damages of no less than a reasonable royalty, with interest; enhanced damages for willful infringement after notice, to the extent proven; a finding that the case is exceptional with attorney fees under 35 U.S.C. 285; and costs. It demands a jury.

Other suits on the same patents

Shenzhen Chitado has asserted the same two patents in Shenzhen Chitado Technology Co., Ltd. v. Windhorse Technologies Inc., No. 1:26-cv-09457 (N.D. Ill.), filed August 7, 2026; Shenzhen Chitado Technology Co., Ltd. v. EKU Inc., No. 2:26-cv-06693 (E.D.N.Y.), filed October 18, 2026; and Shenzhen Chitado Technology Co., Ltd. v. Howling Moto LLC, No. 1:26-cv-13032 (N.D. Ill.), filed October 22, 2026. The Howling Moto and EKU cases accuse the C2 Cargo, C3 and C3 Max models.
