Shangrao Shixuan E-Commerce Co., Ltd. d/b/a Inkgo

Shangrao Shixuan E-Commerce Co., Ltd. (Chinese: 上饶石轩电子商务有限公司), doing business as Inkgo, is a private Chinese e-commerce seller headquartered in Shangrao, Jiangxi Province. It has no public ticker and no disclosed corporate parent; no reliable public source for its founding year, headcount, or revenue was found, and Chinese registry records were not accessible in this search. It appears to be a small, single-brand online retail operation rather than a manufacturer.

Products/operations. Inkgo is an online storefront brand selling third-party, Epson-compatible ink cartridges — typically remanufactured or "compatible" replacements marketed for Epson WorkForce/Expression printers. Epson's complaint describes filled ink cartridges sold under Shangrao's Inkgo name on Amazon, and an Amazon listing shows "Sold by INKGO" for remanufactured Epson 212XL cartridges. There is no evidence in the sources reviewed that Shangrao Shixuan manufactures cartridges; it functions as an e-commerce reseller/importing seller.

Litigation posture. The company's only tracked appearance is as a defendant (0 plaintiff cases), consistent with an operating retailer being attacked, not a patent assertion entity. It was named as a respondent in the Section 337 complaint filed at the U.S. International Trade Commission on May 13, 2025 by Epson Portland Inc., Epson America, Inc., and Seiko Epson Corporation, alleging infringement of five Epson patents (U.S. Nos. 8,764,172; 9,370,934; 11,535,038; 12,240,248; 12,240,249) by imported Epson-compatible ink cartridges. The ITC instituted parallel investigations 337-TA-1451 and 337-TA-1452 on June 12, 2025, naming roughly twenty Chinese and U.S. sellers (Ocbestjet, Tatrix, Upriin, Hookink, HaloFox, Toner Kingdom, and others). This is an ITC/import case, not an Eastern District of Texas docket.

Notable context. In both investigations the Commission terminated Shangrao Shixuan (along with Jianjai, Triple-Color, and 7-magic) as unserved respondents, based on complainants' unopposed withdrawal of the complaint — Order Nos. 11/12, unreviewed in December 2025/January 2026. No merits finding was entered against the company. Other respondents were found in default, and the Commission ultimately issued a general exclusion order in TA-1452.
