Enforces patents representing critical components of its broad intellectual property portfolio and reflecting key investments and innovations in clear aligner therapy, including multilayer aligner material, cutting-edge treatment planning, and advanced aligner features

Align Technology, Inc. (“Align”) (Nasdaq: ALGN), a leading global medical device company that designs, manufactures, and sells the Invisalign® System of clear aligners, iTero™ intraoral scanners, and exocad™ CAD/CAM software for digital orthodontics and restorative dentistry, today announced the filing of patent infringement lawsuits against Angelalign Technology, Inc. (“Angel”) (Hong Kong Stock Exchange: 6699.HK), a Shanghai-based manufacturer of clear aligners. The lawsuits allege that Angel’s products and associated software infringe Align patents, which encompass innovations such as multilayer aligner materials, cutting-edge treatment planning, and advanced aligner features.

These legal actions have been initiated in the United States, Europe and China, jurisdictions where Align has made significant investments in innovation, aligner fabrication and treatment planning. Align seeks both injunctive relief and monetary damages through these intellectual property enforcement efforts.

“Align is a pioneer in orthodontics, investing over $300 million annually (and approximately $2 billion since 2001) in research and development. It’s an unrivalled level of investment that shows clearly our unwavering commitment to our customers and their patients. Our vision and passion for helping doctors transform the orthodontic industry from analog to digital through sustained investments fuels the company’s innovation and technological leadership and advances orthodontic care around the world,” said Julie Coletti, EVP, chief legal and regulatory officer. “We welcome fair and innovative competition, but we will protect our own innovations when companies choose to infringe our years of hard work and investment instead of legitimately performing research and development of their own. The patents we are asserting represent important components of our broad intellectual property portfolio and reflect key innovations in clear aligner therapy.”
