Bearing and Gear Lubrication Regimes: Who Holds the Patents
Sharp acceleration, not a mature field. Filings ran from 1 in 2021 to 8 in 2024, a +700% rise over three years, with 2025 the peak year so far at 11. Filings sat near zero through 2017 and climbed steadily to 8 in 2024, a +700% increase over that three-year span; 2025 posted 11 published records, the highest so far, though later years will keep revising upward as publications catch up to filing dates.

Common questions on this landscape
Who are the leading patent holders in bearing and gear lubrication regimes?
The ranked list covers 47 companies, and the leader holds 6 of the 55 records in scope, with fifth place at 4 and tenth place at 2. That is a shallow lead rather than a dominant position: the top 5 combined hold 45.5% of all records, leaving more than half the field to a long tail of single- or few-filing entrants including universities and individual inventors. No single assignee controls the space outright, so a freedom-to-operate review needs to check several mid-ranked families, not just the top name.
Is patent filing in this area growing or slowing down?
Filing has grown sharply and recently: from 1 record in 2021 to 8 in 2024, a +700% increase over three years, with 2025 posting 11 published records, the highest year so far. Because publication typically lags filing by around 18 months, the 2025 and 2026 counts are still incomplete and should not be read as a plateau or decline. Treat 2024 as the most recent year with a reliable count when judging momentum.
What technology areas dominate the patent claims here?
G06F, electric digital data processing, appears on 58.2% of the 55 records, ahead of F16C (shafts, bearings and couplings) at 20.0% and F16H (gearing and transmissions) at 10.9%. Smaller but present classes include grinding and polishing (B24B), gear cutting (B23F), valve gear (F01L) and testing/measurement (G01M). The heavy G06F presence suggests much of the recent claim activity frames lubrication regimes through sensing, modelling or control rather than purely mechanical design, which matters when scoping a search or a design-around.
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 Bearing and Gear Lubrication Regimes 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.
