Shenzhen Hongxinyuan E-Commerce Co., Ltd. d/b/a Jianjai / Vi-US

Let me verify further details about the company and its online storefronts.

Shenzhen Hongxinyuan E-Commerce Co., Ltd. (深圳市鸿馨源电子商务有限公司), which does business as Jianjai and Vi-US, is a privately held Chinese e-commerce entity registered in Shenzhen, Guangdong. Chinese corporate-registry data (Baidu Baike/Aiqicha) show incorporation on 4 November 2022, with a registered office in Longhua District, Shenzhen, and legal representative Zhang Hao. No public source verifies employee count, revenue, or parent ownership; it appears to be a small independent online seller, not a subsidiary of a listed group.

Its registered business scope is broad online retail and wholesale — internet sales, apparel and general merchandise, home appliances, kitchenware, advertising and IT consulting services, plus Class I–III medical device and food sales. In U.S. trade proceedings it is identified as an importer/seller of aftermarket (compatible) ink cartridges for Epson inkjet printers, sold under the Jianjai and Vi-US names. No source reviewed indicates it manufactures products, holds a patent portfolio, or asserts patents.

It is therefore an operating company, not an NPE. In the tracked data it appears once, solely as a defendant (0 plaintiff cases, 1 defendant case), and that case is an ITC Section 337 import investigation rather than a district-court suit. It shows no patent-assertion activity.

The tracked case is Epson Portland Inc. et al. v. Dongguan Ocbestjet Digital Technology Co., Ltd. d/b/a Ocbestjet et al. (ITC, 337-TA-1451; complaint filed 13 May 2025, instituted 12 June 2025). Epson America, Epson Portland, and Seiko Epson alleged infringement of five U.S. patents ('347, '508, '037, '150, '539) and sought exclusion and cease-and-desist orders. Public USITC and Federal Register notices also name the company as a respondent in the companion investigation 337-TA-1452 (a different patent family), a separate proceeding not reflected in the database's case list. Those notices show the company was terminated from the investigations in January 2026 after the complainant's withdrawal, having earlier been among respondents noted as non-answering/defaulting. The actions sit within a cluster of ITC complaints against Chinese and U.S. sellers of Epson-compatible cartridges.
