The announcement reveals that ITC will issue a Limited Exclusion Order (LEO), prohibiting unauthorized infringing oil atomization devices, their components, and products containing them from entering the US market. Additionally, cease and desist orders (CDO) have been issued against two defendants. The investigation in this case has concluded with the ruling.

According to the announcement, this case was originally filed on March 6, 2024, involving US patent numbers 11,369,756, 11,766,527, 11,369,757, and 11,759,580. The defendants include STIIIZY (STIIIZY IP LLC, STIIIZY, Inc., etc.) and ALD (ALD Group Limited, ALD Hong Kong Holdings).

In terms of program progress, the Administrative Law Judge (ALJ) issued a final initial determination (FID) on March 6, 2025, at which time it concluded that the complainant did not meet the domestic industry economic requirements for violating 337 for reasons such as "not meeting domestic industry economic requirements". Subsequently, the ITC conducted a review of the relevant findings, and after remand for reconsideration, the ALJ determined on July 18, 2025 that the complainant did meet the domestic industry economic requirements. Finally, the ITC reached a final determination that the violation constituted a violation of 337, and decided to issue remedies such as LEO and CDO.
