U.S. International Trade Commission Launches New Investigation
Estimated reading time: 2–4 minutes
The U.S. International Trade Commission (USITC) has started a new investigation. This investigation is about certain oil vaporizing devices and their components. These products are involved in an ongoing case.
The investigation, called “Investigation No. 337-TA-1392,” is under the enforcement section. It focuses on companies named STIIIZY and ALD. These companies may not have followed previous orders that told them to stop certain actions. These orders were made on January 20, 2026.
In March 2024, a company called PAX Labs, Inc. filed a complaint. They said that STIIIZY and ALD were infringing on their patents. These patents include U.S. Patent Nos. 11,369,756, 11,766,527, 11,369,757, and 11,759,580. The complaint was about devices being imported and sold in the U.S. that violated these patents.
PAX Labs also claimed that STIIIZY and ALD were hurting a domestic industry. In January 2026, the USITC found that these companies violated the law. They issued orders to stop their actions and included a 100% bond requirement.
On May 19, 2026, PAX filed another complaint. They said STIIIZY and ALD are still importing and selling these products. They asked for another enforcement proceeding. The USITC agreed that this request meets all requirements.
The commission has assigned a Chief Administrative Law Judge to handle this case. They will look into whether the companies violated any orders. Then, they will decide on the necessary enforcement actions.
The authority for these actions comes from section 337 of the Tariff Act of 1930. The USITC’s rules also provide guidance. The commission’s vote for this decision took place on June 5, 2026.
Lisa Barton, the Secretary of the Commission, is responsible for this order. The Federal Register will publish the full notice, including the related orders.
