Compressors & Blowers Patents: Who Leads and Where Filing Is Heading
Concentration is modest. the ranked leader holds 1,340 records but the top 5 combined account for only 12.9% of all 36,448 records in scope — no single filer dominates this field. Annual output moved from 766 records in 2017 to a peak of 1,060 in 2021, then declined to 627 by 2024 — a 41% drop over that three-year window. Years after 2024 are still incomplete due to publication lag and should not be read as a continued fall.

Compressor and blower patents: common questions
Who are the leading patent holders in compressor and blower technology?
The ranked leader in this dataset holds 1,340 records, with fifth place at 699 and tenth place at 388, so leadership drops off quickly after the top handful of names. Even so, the top 5 assignees combined account for only 12.9% of the 36,448 records in scope, and the top 10 reach 19.2%. That means the large majority of filing activity sits with a long tail of companies rather than a concentrated few, so a competitive review should look well beyond the top names to get a full picture of who is active in a specific sub-area.
Is compressor and blower patent filing activity growing or slowing down?
Filing activity rose from 766 records in 2017 to a peak of 1,060 in 2021, then declined to 627 by 2024 — a 41% drop over that three-year period. Years after 2024 show lower counts still, but that reflects publication lag of roughly 18 months rather than a confirmed drop in filing behaviour, since not all recent filings have published yet. The safest reading is that activity eased from a 2021 high through the last complete year of data, with the very latest years still provisional.
Which patent classes cover the most compressor and blower filings?
F02C, covering gas-turbine plants, is the largest single IPC subclass at 10.9% of the 36,448 records, ahead of F01D (turbines and non-positive engines) at 6.2% and F04D (non-positive-displacement pumps) at 6.0%. Separation processes (B01D), gas liquefaction (F25J), hydrocarbon refining (C10G), catalysis (B01J) and positive-displacement pumps (F04B) each cover a further 3-5% of records. Because a single record can carry multiple IPC classes, these figures add up to more than 100% and should be read as overlap, not as a partition of the field.
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 Compressors & Blowers 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.
