Turbomachinery Components Patents: Top Companies & Filing Trends 2026
Turbomachinery Components Patents: Who Leads and Where the Field Is Still Open
62.8% of all activity sits with five companies. 554 of 882 records in scope belong to the top five assignees — a field where claim space is already staked out at the top. Filings peaked in 2017 at 156 and have run lower since, falling to single digits by the tail of the window as expected under the publication lag. The 2021-to-2024 window is the fairer read of current activity: 49 to 53 filings, an 8% rise, indicating the field is still being actively claimed rather than abandoned.

Common questions about turbomachinery component patents
Who holds the most patents on turbomachinery components?
Filing in this dataset is heavily concentrated: the leading assignee holds 170 of the 882 records in scope, and the top five assignees combined hold 554 records, or 62.8% of the field. That gap is wide enough that a single company’s filing strategy effectively sets the boundaries of the core claim space. Below the top ten, which together hold 76.8% of records, the remaining 90 ranked companies each hold comparatively few filings, forming a long tail rather than a second tier of equal-sized competitors.
Is turbomachinery component patent filing still growing?
Filing peaked in 2017 at 156 records and has settled to a lower, steadier level since. Looking only at complete years, filings rose from 49 in 2021 to 53 in 2024, an 8% increase — modest but real growth. The apparent drop in 2025 and 2026 is largely an artefact of the roughly 18-month lag between filing and publication, not evidence that the field is contracting.
What technology areas dominate turbomachinery component patents?
Two IPC subclasses carry most of the field: F01D, covering turbines and non-positive engines, appears on 50.6% of the 882 records, and F02C, gas-turbine plants, appears on 46.9%. Steam and thermal power plants (F01K) and non-positive-displacement pumps (F04D) form a smaller second tier. Combustion chambers, jet and reaction propulsion, and aircraft equipment each sit at or below 7%, marking them as narrower, more specific claim territory rather than core ground.
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 Turbomachinery Components 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.
