European Court Rules Angelalign Infringed Align Technology Patent
The Unified Patent Court's Paris Local Division ruled on Oct. 16 that Angelalign clear aligner systems using Torque Ridges technology infringe a European patent held by Align Technology, Inc. (NASDAQ:ALGN). The decision orders the recall and destruction of infringing items across 17 European markets, including France, Germany, Italy, and the Netherlands, alongside an award for damages and other relief. The ruling follows infringement proceedings launched in August 2025.
The court outcome helps Align Technology protect its competitive stance for Invisalign clear aligners in Europe by restricting a key competitor's use of disputed technology. Angelalign rejected validity arguments but has since discontinued Torque Ridges in Europe, substituting a feature called Pressure Points. While Align disputed Angelalign's characterization of the change as an upgrade, the precise financial damages and revenue effects remain undisclosed.
Investors should monitor ongoing patent disputes between the two manufacturers across multiple jurisdictions. Angelalign is appealing the European decision, while appealing a separate August decision in China concerning treatment-planning software. Meanwhile, an initial determination from the U.S. International Trade Commission regarding five disputed Align patents is expected in November 2026. Shares of Align Technology recently traded down 1.36% at 147.3 USD.
