Pumps and pumping systems patents: who is filing, what they claim, and where the gaps sit
Filing has cooled from its 2019 peak. 994 records that year against 555 in 2024, a -40% swing from 2021's 931 — though 2025-26 figures are still filling in as publication catches up with filing. Filings rose to a peak of 994 in 2019, then eased. The clearest complete-year comparison is 2021's 931 against 2024's 555, a -40% move over three years; treat 2025 and 2026 (43 so far) as still-arriving data rather than a real decline.

Common questions on pumps and pumping systems patents
Who holds the most patents in pumps and pumping systems?
One assignee leads the ranked field with 1,007 records, well ahead of fifth place at 332 and tenth place at 178. That said, the top 5 assignees combined hold only 13.1% of all 22,969 records in scope, and the top 10 hold 18.4%, so no single company controls the field. The remainder is spread across a long tail of the ranked leaders with far lower filing counts, which is typical for a search spanning medical, oilfield and mechanical pump applications at once.
Is patent filing in pumps and pumping systems growing or declining?
Filing peaked at 994 records in 2019 and had fallen to 555 by 2024, a -40% change across the last three complete years on record (2021 to 2024). The 2025 and 2026 figures look much lower still, but that reflects the roughly 18-month lag between filing and publication rather than an actual collapse in activity. The safest complete-year comparison to quote is the 2021-to-2024 span rather than anything involving the final two years.
What technology areas dominate pump-related patent filings?
A61M, the IPC class covering devices for body fluids, is the largest single category at 17.0% of the 22,969 records in scope, ahead of E21B earth and well drilling pumps at 12.2% and F04B positive-displacement pumps at 11.2%. Smaller but still active classes include G01N material testing, B01D separation processes, and F04D non-positive-displacement pumps. Because records can carry multiple IPC codes, these shares add up to well over 100% and should not be read as parts of a single whole.
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 Pumps & Pumping Systems Patent Landscape covering 2015–2026, data cut-off 2026-08-31. 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.
