Asset Condition Monitoring Patents: Who Leads, Trends 2026
Asset Condition Monitoring in Substations: Patents, Leaders and Filing Trends
Concentrated at the top. The top 5 assignees hold 66.0% of all 47 records in scope, and the top 10 hold 83.0% — a long tail of single-filing entrants fills the rest. Filings rose from zero in 2017 to a peak of 10 in 2021, then declined to 5 by 2024 — a -50% move over that span. 2025 and 2026 counts will continue to fill in as publications catch up with filing dates.

Common questions on this landscape
How many patents cover asset condition monitoring in substations?
This landscape identifies 47 published patent families in scope, filed between 2015 and the 2026-07-31 data cut-off. The search combines monitoring methods such as partial discharge monitoring and dissolved gas analysis with practical filing terms like sensor installation retrofit, trend analysis and remaining-life estimation. Because publication lags filing by roughly 18 months, the true number of filings in 2025 and 2026 will be higher than currently shown once those applications publish.
Who are the leading patent filers in substation asset condition monitoring?
The ranking covers 43 assignees, with the leader holding 11 of the 47 records in scope — well ahead of fifth place, which holds 3. The top 5 assignees together account for 66.0% of all records, and the top 10 account for 83.0%, meaning a small group of grid operators, university researchers and high-voltage equipment manufacturers control most of the documented claim space while the rest is a long tail of single-filing entrants.
Is patent filing activity in this field growing or slowing down?
Filings rose from zero in 2017 to a peak of 10 in 2021, then fell to 5 by 2024, a -50% change over that three-year span. That is the most reliable read available, because 2021-2024 are complete years; the 2025 and 2026 figures shown in any chart are still filling in due to the roughly 18-month gap between filing and publication, so they should not be read as confirming a continued 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 Asset Condition Monitoring in Substations 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.
