Bearing RUL Prediction Patents: Leaders, Trends & White Space 2026
Bearing Remaining-Useful-Life Prediction Patents: Who Holds the Claim Space
One filer holds 352 records, well ahead of the field, while the ranked leaders' combined top 5 still only reach 24.2% of all 3,086 records in scope. Volume climbed through the late 2010s and plateaued in the low-to-mid 2020s: 2021 (261) to 2024 (252) moved -3%, the last span long enough to read as complete given the roughly 18-month lag between filing and publication. 2026 figures (283 so far) are still filling in.

Common questions on this landscape
Who holds the most patents on bearing remaining-useful-life prediction?
One assignee leads the field with 352 records, well ahead of the fifth-ranked filer at 53 and the tenth-ranked filer at 36. The top 5 assignees combined account for 24.2% of all 3,086 records in scope, and the top 10 combined reach 30.6%. That means the majority of filings sit outside this ranked leadership group, spread across a long tail of single- or few-filing entrants including established industrial-equipment makers and diversified technology firms.
Is the number of bearing RUL prediction patents still growing?
Filing volume grew from 96 in 2017 to a peak of 375 in 2025, but the most recent fully comparable span (2021 to 2024) actually moved -3%, from 261 down to 252. Because publication lags filing by roughly 18 months, the 2025 and 2026 figures will revise upward over time, but the underlying signal is a plateau rather than continued acceleration. Treat this as a mature, densely occupied claim space rather than an emerging one.
What patent classes cover bearing remaining-useful-life prediction technology?
The dominant classifications are G05B (control and regulating systems, 40.3% of the 3,086 records) and G06N (AI-based computing, 35.3%), often appearing together on the same filing. G06Q business-process classes cover 23.9% and G06F digital data processing 20.5%. Pure sensing and measurement classes such as G01M and G01R sit well below 11% each, showing that most claims wrap prediction logic into a control or software layer rather than staying at the sensor level.
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.
