Maintenance & Asset Integrity Patents: Top Filers & Trends 2026
Maintenance & Asset Integrity Patents: Who Holds the Ground
71.6% concentration. The top 5 assignees account for 58 of 81 records in scope — filing here is dominated by a small group, not spread across a long tail. Filings climbed to a peak of 19 records in 2021, then fell to 1 record in 2024 — a 95% drop over that three-year span. 2025 and 2026 figures are still incomplete because publication lags filing by roughly 18 months, so the apparent tail should not be read as the field going quiet; it is a reporting artefact until later data lands.

Common questions about this landscape
Who are the leading patent holders in maintenance and asset integrity technology?
The assignee ranking for this dataset covers 28 companies, and it is heavily concentrated: the top 5 assignees together hold 58 of the 81 records in scope, or 71.6%. The single leading assignee holds 20 records on its own, well ahead of fifth place at 5 and tenth place at 2. This means a new entrant should expect to negotiate around a small number of established portfolios rather than a fragmented field of similarly sized players.
Is patent filing in this field growing or slowing down?
Filing peaked at 19 records in 2021 and fell to 1 record by 2024, a 95% drop over that span, which is the most recent year the trend can be read as complete. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so those final years understate real activity and should not yet be read as confirmation of a continued decline. The honest read is that the field cooled sharply after 2021, with the very latest trajectory still unresolved.
What technology areas dominate maintenance and asset integrity patents?
Flow, level and volume measurement (IPC class G01F) is the largest single category, appearing in 23.5% of the 81 records in scope. Electric and magnetic measurement (G01R) and power supply and grid systems (H02J) are tied just behind at 17.3% each, ahead of business/admin data processing (G06Q) at 13.6%. Because a single record can carry multiple IPC classes, these shares add up to more than 100%, but the pattern is consistent: physical sensing and power-systems claims outweigh pure software analytics in this field.
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.
