I'll research this company to build a factual profile.
Let me verify the litigation context and note the Align Technology dispute history.
Company overview. Angelalign Technology Inc. (時代天使; short name "Angelalign") is a Cayman Islands-incorporated, Hong Kong-listed holding company (HKEX: 6699; OTC: AGLFF) whose operating business was founded in 2003 by Li Huamin and is headquartered in Shanghai's Yangpu District. The Cayman holding entity was incorporated in 2018. Some data providers list CareCapital Orthotech Limited as a shareholder/affiliate; the company is publicly traded. FT data (Sept 2026) reports roughly 4,480 employees. Reported FY2025 revenue was USD 370.3 million (up 37.8%) with net profit of USD 26.3 million; H1 2026 revenue was USD 230.7 million.
Products / operations. Angelalign designs, manufactures and sells clear aligner treatment solutions and related digital orthodontics services for dental professionals, hospitals, clinics and distributors. Product lines include angelalign (mass market), angelalign Pro (premium), Angel Aligner KiD (pediatric/early treatment), and COMFOS; accessory/clinical systems include angelButton, angelAttach, and masterControl S multilayer material. It operates the iOrtho digital orthodontic treatment-planning platform, sells intraoral scanners, and offers treatment-planning and clinical-support services. It operates across mainland China and 60-plus countries, with treatment-planning centers in Brazil and Southeast Asia, a Brazil manufacturing site, and a U.S. facility under development. It has made strategic investments including Aditek (Brazil) and Shuyaqi.
Patent-litigation posture. Angelalign is an operating company, not an NPE. In the tracked data it appears once, as a defendant (0 plaintiff cases, 1 defendant case) — consistent with a product company on the receiving end of infringement claims rather than an asserter.
Notable case. Align Technology, Inc. v. Angelalign Technology Inc. et al., No. 2:25-cv-00804 (E.D. Tex., Marshall Division, Judge J. Rodney Gilstrap), filed August 18, 2025, with an amended complaint on September 26, 2025; co-defendants include Shanghai EA Medical Instruments, Wuxi EA Bio-Tech, and Wuxi EA Medical Instruments Technologies. Asserted patents concern aligner multilayer material and features such as Power Ridges and Bite Ramps. Align filed a parallel ITC Section 337 complaint (September 2025), and the district case was subject to an unopposed motion to stay pending the ITC proceeding. Parallel actions were also filed in China and at the UPC's Düsseldorf Local Division.
