U.S. International Trade Commission Updates on Clear Aligners Investigation
Estimated reading time: 1–7 minutes
On June 8, 2026, the U.S. International Trade Commission (ITC) announced a decision regarding an investigation about clear aligners. These aligners are devices used in orthodontics to straighten teeth.
The investigation was started on December 29, 2025. Align Technology, Inc., a company from Tempe, Arizona, filed a complaint. They claimed that other companies sold clear aligners and parts made using their patented technologies. The patents in question are several U.S. Patents, including numbers `313, `314, `977, `616, and others.
The companies being investigated are mainly from China. They include Angelalign Technology Inc. and Wuxi EA Medical Instruments, among others. There is also a company from Newark, Delaware involved. These companies are referred to as the Respondents.
Align Technology sought to change its complaint. They wanted to add new claims of patent infringement. They also wanted to remove some original claims. On April 14, 2026, they filed a motion to make these changes. Respondents opposed this motion, saying Align had enough information when they first filed the complaint.
On May 11, 2026, the Respondents filed a petition. They challenged the ITC’s decision that allowed Align to amend its complaint. Align filed a response on May 18, 2026.
After reviewing all documents and submissions, the ITC decided not to review the decision further. This decision means that the investigation will continue with the new claims added. These include claims 24 from patent `313 and claim 28 from patent `314, among others.
The ITC made this determination on June 3, 2026. They stated that these changes would make future processes more efficient. The investigation is governed by section 337 of the Tariff Act of 1930 and related Rules of Practice.
The ITC provided the authority for these actions, ensuring the investigation proceeds smoothly. They emphasized that this process aims to use resources wisely and maintain fairness.
