The U.S. International Trade Commission (USITC) voted to institute an investigation of certain wearable breast pumps, associated milk storage containers, and components thereof. The products at issue in the investigation are described in the USITC’s notice of investigation.

The investigation is based on a complaint filed on behalf of Willow Innovations, Inc. of Mountain View, California, and Willow Blossom HoldCo Ltd. of London, United Kingdom, on August 20, 2026. The complaint alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain wearable breast pumps, associated milk storage containers, and components thereof that infringe certain claims of the patents asserted by the complainants. The complainants request that the USITC issue a limited exclusion order and cease and desist orders. 

The USITC has identified the following respondents in this investigation:

• Shenzhen Root Innovation Technology Co., Ltd., Shenzhen, China
• Hong Kong Lute Technology Co., Ltd., Aurora, Colorado 
• Root Technology, Ltd., Beverly Hills, California 
• Share Info, Inc., Flushing, New York 
• Shenzhen TPH Technology Co., Ltd., Shenzhen, China 
• Guangdong Horigen Mother & Baby Products Co., Ltd., Shantou City, China 
• Anker Innovations Limited Unit, Hong Kong 
• Fantasia Trading, LLC, Ontario, California 
• Power Mobile Life LLC, Bellevue, Washington 
• TPH Technology Malaysia Sdn Bhd, Selangor, Malaysia 
• Foshan Shunde Ruiteng Electrical Appliance Manufacturing Co., Ltd., Foshan City, China
• Guangdong Youmeng Electrical Technology Co., Ltd., Foshan City, China 

By instituting this investigation (337-TA-1522), the USITC has not yet made any decision on the merits of the case. The USITC’s Chief Administrative Law Judge will assign the case to one of the USITC’s administrative law judges (ALJ), who will schedule and hold an evidentiary hearing. The ALJ will make an initial determination as to whether there is a violation of section 337; that initial determination is subject to review by the USITC. 

The USITC will make a final determination in the investigation at the earliest practicable time. Within 45 days after institution of the investigation, the USITC will set a target date for completing the investigation. USITC remedial orders in section 337 cases are effective when issued and become final 60 days after issuance unless disapproved for policy reasons by the U.S. Trade Representative within that 60-day period.
