Breast Pumps Patents: Who Leads, Where the Gaps Are 2026
Breast Pump Patents: Filing Trends, Leading Assignees and Open Claim Space
69.3% of all 599 records sit with just five assignees — filing here is concentrated at the top, not spread across a long tail. From 55 families in 2017, filings climbed to a peak of 89 in 2021, then dropped to 24 by 2024 — a 73% decline over that three-year span. 2025 and 2026 figures are still incomplete because of the roughly 18-month gap between filing and publication, so the apparent drop-off should not be read as the field cooling further than the 2021-2024 figures already show.

Common questions about breast pump patents
How many breast pump patents have been filed?
This dataset covers 599 published records filed between 2015 and mid-2026, drawn from a search targeting suction pattern, noise level, milk pathway hygiene, battery life, flange fit and expression efficiency terms. Filing activity peaked in 2021 at 89 families before falling to 24 by 2024, the most recent year that can be treated as complete given the roughly 18-month publication lag. The true count for 2025 and 2026 will rise as those years finish publishing.
Who are the leading breast pump patent holders?
The field is concentrated: the top 5 assignees hold 69.3% of all 599 records in scope, and the top 10 hold 84.3%. The leading assignee alone holds 135 records, well ahead of the fifth-place holder at 25 and the tenth-place holder at 9. Past the top ten, the remaining 68 ranked companies each hold a small share, so competitive tracking should focus on the leaders rather than a broad field.
What technology areas do breast pump patents cover?
Almost all records, 92.7% of the 599 in scope, fall under IPC class A61M for body-fluid devices, which covers the core pumping mechanism. Smaller but notable classes include A61J for medicine containers (10.0%), G16H for healthcare informatics (6.2%), and F04B for positive-displacement pumps (3.8%). Classes tied to wearable integration (A41C, 3.3%) and solid-state actuation (H10N, 2.3%) are present but thin relative to the core mechanism, since records can carry multiple classes these percentages sum to more than 100%.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Breast Pumps covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
