High Speed Turbo Blowers for Aeration Patents: Top Filers 2026
High speed turbo blowers for aeration: who holds the patents and where the field is still open
Concentrated at the top. the five most active filers account for 67.6% of all 74 records in scope, and the top ten hold 82.4%. Filings ran from 5 in 2017 to a peak of 10 in 2021, then declined to 1 by 2024, a 90% fall over that three-year window. Later years in the chart understate true filing volume because of the normal publication lag, so the 2025-2026 figures should not be read as confirming a continued drop.

Common questions about this landscape
Who are the leading patent holders in high speed turbo blower technology for aeration?
The dataset ranks 40 assignees, with a single top-ranked company holding 20 of the 74 records in scope, well ahead of the fifth-place filer at 5. The top five assignees combined account for 67.6% of all records, and the top ten reach 82.4%, so the field has a short leader group followed by a long tail of filers with one or two records each. Anyone evaluating competitive position should look closely at the top five before assuming the field is open.
Is patent filing for turbo blower aeration technology growing or slowing down?
Filing activity peaked in 2021 at 10 records and had fallen to 1 by 2024, a 90% decline over that three-year span. Because patent publication typically lags filing by around 18 months, the 2025 and 2026 figures in the underlying data are still incomplete and should not yet be read as confirming a further drop. Based on the last fully-formed year, 2024, the trend is a genuine slowdown from the 2021 peak.
What patent classifications cover high speed turbo blower and aeration technology?
The largest share of records, 36.5% of 74, carry a C02F wastewater-treatment classification, reflecting how many filings claim the blower as part of an aeration or treatment process rather than as a standalone machine. F04D non-positive-displacement pumps follow at 21.6%, with B01D separation processes at 14.9% and H02K electric motors at 13.5%. Because a single record can carry multiple classifications, these shares should be read individually against the 74-record total rather than summed.
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.
