The US ITC has officially launched a 337 investigation into evaporator equipment, smoke bombs used, and their components

On December 16, 2025, the United States International Trade Commission (ITC) voted to initiate a 337 investigation (investigation code: 337-TA-1464) into certain evaporator devices, cartridges used with them, and components thereof.

On November 18, 2025, JUUL Labs, Inc. of Washington, D.C. and VMR Products LLC of Washington, D.C. filed a 337 investigation application with the US ITC, claiming that the product exported, imported, and sold in the United States violated US Section 337 (infringing US registered patent numbers 11134722 and 11606981), and requested the US ITC to issue a limited exclusion order and injunction.

Glas, Inc. of Los Angeles, California and Glas, LLC of Los Angeles, California are listed defendants.

The US International Trade Commission will determine the end date of the investigation within 45 days after filing the case. Except in cases where the United States Trade Representative vetoes a relief order based on policy reasons, the relief order issued by the United States International Trade Commission in the 337 case shall take effect from the date of issuance and shall have final effect on the 60th day after the date of issuance.
