Power Skiving Internal Gear Patents: Leaders & White Space 2026
Power Skiving of Internal Gears Patents
Filings peaked in 2019 at 12 records and the 2021→2024 span shows a -100% swing, though 2025-2026 counts are still filling in under the usual 18-month publication lag. Activity peaked at 12 records in 2019. The evidence-backed comparison of 2021 (5 records) to 2024 (0 records) shows a -100% swing over that three-year span; treat 2025 and 2026 as still filling in rather than as evidence of a further decline, since publication typically lags filing by around 18 months.

Common questions on power skiving patents
What does a power skiving patent typically claim?
Most records in this dataset claim some combination of the cutting tool geometry, the crossed-axis angle between tool and workpiece, and the control strategy used to manage chip formation during the cut. A smaller share claims the surrounding machine tool fixture or the software that calculates tool tilt in real time. Because 86.2% of the 29 records touch the B23F gear-and-thread-cutting subclass, the mechanical cutting process itself is the most heavily claimed area, while control and software claims remain comparatively rare.
Who are the leading patent holders in power skiving of internal gears?
The ranked list returned for this dataset covers 10 companies, with the leader holding 10 records and the ranking narrowing quickly to 2 records by fifth place and 1 by tenth. That pattern points to a small group of established gear-machinery manufacturers holding most of the claimed ground, with individual inventors and academic filers making up the tail. This is the complete ranking the data endpoint returns for this search, not a curated top-50 or top-100.
Has power skiving patent filing activity been growing or slowing?
Filing activity peaked at 12 records in 2019, the busiest year in this dataset. Comparing 2021 (5 records) to 2024 (0 records) shows a -100% change over that span, but 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months. Read the recent years as filling in rather than as confirmation of a continuing decline.
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 Power Skiving of Internal Gears covering 2015–2026, data cut-off 2026-07-31. 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.
