Aeroelasticity and Blade Vibration Patents in Turbomachinery
Concentrated at the top. the five leading filers hold 31.6% of all 1,028 records in scope, and the top ten hold 43.6% — a small group of turbine OEMs still controls most of the claim space. Annual filings rose to a peak of 65 records in 2021, then declined to 21 by 2024 — a -68% move over that three-year span. Records published in 2025 and 2026 will continue to fill in as the roughly 18-month gap between filing and publication closes, so the most recent bars understate actual filing activity rather than confirm a slowdown.

Common questions on this landscape
Who holds the most patents on blade vibration and aeroelasticity in turbomachinery?
One assignee leads clearly with 107 records in this 1,028-record dataset, well ahead of fifth place at 32 and tenth place at 22. The top five filers together hold 31.6% of all records and the top ten hold 43.6%, so filing is concentrated among a small group of turbine OEMs and energy majors rather than spread evenly. Past the top ten, the ranking includes a long tail of companies and research institutions each holding only a handful of records.
Is patent filing in this field growing or slowing down?
Filing peaked at 65 records in 2021 and fell to 21 by 2024, a -68% move over that three-year span using the most recent years that can be treated as complete. Counts for 2025 and 2026 are still low, but that reflects the roughly 18-month lag between filing and publication rather than a confirmed continued decline. Any read on the very latest years should wait for those records to finish publishing.
What technology areas dominate blade vibration patents?
F01D, covering turbines and non-positive-displacement engines, appears in 48.2% of the 1,028 records and anchors the field to the mechanical turbine stage. G01H vibration measurement (16.2%) and G01M structural testing (10.4%) form a substantial secondary layer focused on detecting and characterizing vibration, while F03D wind turbines (9.6%) and G06F data processing (8.4%) mark distinct hardware and software adjacencies. Because a single record can carry multiple IPC classes, these percentages add up to more than 100% of the record total.
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.
