Wuxi EA Bio-Tech Co., Ltd. (无锡时代天使生物科技有限公司, also rendered "Wuxi EA BioTech Co., Ltd.") is a China-based medical-device manufacturing company incorporated on 11 July 2018 and headquartered at No. 36 Guanshan Road, Xinwu District, Wuxi, Jiangsu. It is a wholly owned subsidiary of Wuxi EA Medical Instruments Technologies Limited (無錫時代天使醫療器械科技有限公司), itself a wholly owned subsidiary of Hong Kong-listed Angelalign Technology Inc. (時代天使科技有限公司), a Cayman-incorporated company listed on the Main Board of the Stock Exchange of Hong Kong. Chinese corporate registry data (Tianyancha/Qichacha) lists registered capital of RMB 400 million and an insured-employee count in the 400–499 band. No separate revenue or market-cap figures are published for this subsidiary.
Operations. The company performs product design, research and development, and manufacturing related to clear orthodontic aligners and treatment solutions. Its registered business scope covers Class I and Class II medical-device production and sales, software development, additive manufacturing/3D printing services, and import/export. Trade records show it exporting Angel Aligner products (including the "Aligner Select" model) under HS 9021101000. The complaint in the tracked case describes Wuxi EA Bio-Tech and affiliate Shanghai EA as conducting product design and R&D for Angelalign's clear aligner treatment solutions. It is an operating manufacturer, not a patent-assertion entity.
Litigation posture. With 0 plaintiff cases and 1 defendant case in the tracked data, the company appears only as a target of infringement claims. The single tracked matter is Align Technology, Inc. v. Angelalign Technology Inc. et al., filed 18 August 2025 in the U.S. District Court for the Eastern District of Texas, Marshall Division, before Judge J. Rodney Gilstrap — a plaintiff-friendly venue, though here it is Align, the market-leading aligner manufacturer, selecting it rather than a shell plaintiff.
Context. The district court suit is one front of a broader dispute: on 23 September 2025 Align Technology filed a Section 337 complaint at the U.S. International Trade Commission naming Wuxi EA Bio-Tech alongside Angelalign Technology Inc., Wuxi EA Medical Instruments Technologies, Shanghai EA Medical Instruments, and USA Angelalign Technology Corp. as respondents. The USITC instituted investigation 337-TA-1471 on 19 December 2025, with Align seeking a limited exclusion order and cease-and-desist orders covering imported clear aligners. The dispute reflects competition in the global clear-aligner market; no merits determination has been made.
