Conductor Temperature Sensing Patents: Who Leads, Line Rating 2026
Conductor Temperature Sensing Patents: Mapping Line Rating Innovation
Concentrated at the top. the five most active assignees hold 71 of 77 records in scope (92.2%), leaving a thin tail below tenth place. Annual filings rose unevenly from 2 records in 2017 to a peak of 7 in 2022, then eased before the 2021→2024 span shows growth of +200% (1 to 3 records). The final two years in the window are still incomplete due to publication lag.

Common questions about this landscape
Who holds the most patents in conductor temperature sensing for line rating?
One assignee leads with 28 of the 77 records in scope, well ahead of the next four ranked companies combined. The top five assignees together account for 71 records, or 92.2% of all records, so the field is concentrated rather than fragmented. Below the top ten, filing activity drops sharply to a single record at tenth place, meaning most competitive attention should focus on the leading group rather than a long tail of small filers.
Is patent filing in dynamic line rating growing or slowing down?
Filings grew from 1 record in 2021 to 3 in 2024, a documented +200% increase over that span, with the field’s peak year so far at 7 records in 2022. The 2025 and 2026 figures look lower, but that reflects an 18-month publication lag rather than an actual decline. Any assessment of current momentum should treat 2024 as the most recent complete year.
What technology areas dominate conductor temperature sensing patents?
H02J, covering power supply and grid systems, appears in 68.8% of the 77 records, making it the most heavily claimed subclass. G01R electric and magnetic measurement follows at 59.7%, and G01K temperature measurement at 54.5%. Because a single record can carry several IPC classes, these percentages overlap and add to more than 100%, so they should be read as separate claim-density signals rather than as a breakdown of the whole 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.
Method: Filing trend and technology composition. Derived from a Patsnap search on Conductor Temperature Sensing for Line Rating 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.
