Feds Investigate Wearable Breast Pumps in Patent Clash

## Summary

Willow Innovations and Willow Blossom HoldCo have asked the U.S. International Trade Commission to investigate certain wearable breast pumps and milk storage containers for patent infringement. This could lead to import bans and sales restrictions in the U.S., affecting companies selling these products. The investigation started in September 2026 and might impact the market and money flow soon.

## Abstract

The complaint alleges violations of section 337 based upon the importation into the United States, the sale for importation, and the sale within the United States after importation of certain wearable breast pumps, associated milk storage containers, and components thereof by reason of the infringement of certain claims of U.S. Patent No. 11,660,380 ("the '380 patent"); U.S. Patent No. 12,370,292 ("the '292 patent"); U.S. Patent No. D1,053,344 ("the D'344 patent"); U.S. Patent No. 11,813,388 ("the '388 patent"); and U.S. Patent No. D1,031,993 ("the D'993 patent"). The complaint further alleges that an industry in the United States exists or is in the process of being established as required by the applicable Federal Statute.
