Products / operations. The company develops and manufactures custom clear aligners and associated orthodontic hardware and software for the Angelalign group.

Patent-litigation posture. Tracked data show one case, as defendant only (0 as plaintiff): Align Technology, Inc. v. Angelalign Technology Inc. et al., filed 18 August 2025 in the Eastern District of Texas, Marshall Division, before Judge J. Rodney Gilstrap — a plaintiff-friendly patent venue. Wuxi EA is one of several named Angelalign-group defendants. The posture is an operating company defending a competitor's infringement suit, not a patent assertion.
Notable cases / context. Align's amended complaint asserts U.S. Patents 11,766,313 and 11,766,314 (multilayer aligner sheet material), 8,899,977 and 12,059,321 (Power Ridge geometry) and 10,980,616 and 11,490,996 (bite ramps), targeting Angel's masterControl material and angelAttach/occlusal-ramp features. Align filed a parallel ITC Section 337 complaint on 23 September 2025; the ITC instituted Inv. No. 337-TA-1471 on 19 December 2025 against five Angelalign-group respondents, and the district court action was moved to stay pending that investigation. Related proceedings are also pending before the UPC.
