US20260097156A1 - Breast Pump Systems and Methods

The USPTO published patent application US20260097156A1, a utility patent application with A1 publication status, covering systems and methods for breast milk expression. The invention describes a breast pump comprising a flange, a milk collection container, a connecting tube, and a pump unit that generates and controls vacuum to express milk from the breast and expel it to the container. The application is classified under CPC codes A61M 1/067, A61M 1/06935, and A61M 1/0697, placing it in the medical devices art unit.

Affected parties including medical device manufacturers, breastfeeding product companies, and lactation technology developers should monitor this application as potential prior art. While a published patent application does not yet constitute granted rights, it establishes a priority date and may inform future patent prosecution. Companies developing competing breast pump or milk expression technology should conduct freedom-to-operate analyses and assess whether the claimed vacuum-controlled expression mechanisms conflict with their existing or planned product lines.
