In September 2025, Align filed a patent infringement action against Angel in the Jinan Intermediate People's Court, asserting Align's patent related to extraction-gap-closure technology (CN113693748B). The court further found that the related aligner products manufactured and sold using the accused technology also infringe Align's patent. "Align has made significant long-term investments in innovation and in the Chinese market," said Joe Hogan, president and chief executive officer of Align Technology.
