Zhuhai Rongtaida Electronics Co., Ltd. d/b/a Hookink

Zhuhai Rongtaida Electronics Co., Ltd. (珠海市荣泰达电子有限公司), which sells under the trade name Hookink, is a privately held Chinese company registered in Xiangzhou District, Zhuhai, Guangdong. Chinese business-registry records (Qixinbao, Tianyancha, Baidu Baike) list a registration date of July 25, 2022, registered capital of RMB 100,000, legal representative Ren Fei, and a registered address at Room 9E‑1, Taihe Business Center, 338 Ningxi Road, Xiangzhou. Its registry classification is "manufacture of computers, communications and other electronic equipment," with business scope including electronic-component manufacturing. No public source gives employee counts or revenue; the small registered capital and short history indicate a micro/small enterprise.

Products / operations. The company is a supplier of third-party (aftermarket) printer consumables. Its US trademark HOOKINK (USPTO serial 97684222, filed November 18, 2022; earlier registration cited as Reg. No. 7253681) covers filled ink cartridges, filled toner cartridges, inkjet printer ink, and toner for printers, copiers, and multifunction devices. It appears alongside numerous Zhuhai/Shenzhen peers in ITC complaints as a low-cost consumables exporter rather than a diversified manufacturer. It is an operating supplier, not a patent-assertion entity.

Patent-litigation posture. The tracked data show 0 cases as plaintiff and 1 as defendant: Rongtaida is a defendant being attacked, not an NPE. The single appearance is a US International Trade Commission Section 337 action — Epson Portland Inc. et al. v. Dongguan Ocbestjet Digital Technology Co., Ltd. d/b/a Ocbestjet et al., filed May 13, 2025 — not a district-court suit, so no plaintiff-friendly district venue applies.

Notable case / context. The complaint by Epson Portland, Epson America, and Seiko Epson Corporation led to ITC investigations 337‑TA‑1451 (Certain Ink Cartridges and Components Thereof I) and 337‑TA‑1452 (…Thereof II), instituted June 12, 2025, asserting Epson patents on ink-cartridge technology and seeking exclusion and cease-and-desist orders. Rongtaida is a named respondent in both; notices of Commission determinations (2025) list it among respondents found in default after ALJ initial determinations.
