Wide Area Measurement & Synchrophasor Patents: Leaders & Trends 2026
Wide Area Measurement and Synchrophasor Patents: Who Leads and Where Filing Is Heading
Concentrated at the top. The five leading assignees together hold 32.5% of all 200 records in scope, and the top ten hold 51.0% — over half the field sits with a small group of filers. Volume rose to a peak of 26 records in 2021, then fell to 7 by 2024 — a 73% decline over that three-year window. 2025 and 2026 figures will continue to rise as publications catch up with filing dates roughly 18 months behind, so the most recent two years understate actual filing activity.

Common questions
What counts as a synchrophasor patent in this landscape?
This landscape scopes records that combine core wide area measurement terms — wide area measurement, phasor measurement unit, synchrophasor data — with specific technical elements such as reporting rate, time-source dependency, oscillation detection, communication architecture, data compression or event-triggered storage. That combination excludes generic grid-monitoring patents that do not address these synchrophasor-specific engineering problems. It results in 200 published records across six receiving offices from 2015 through the 2026 data cut-off.
Who are the leading patent holders in wide area measurement and synchrophasors?
The field is led by a small group of grid-equipment manufacturers and utility-affiliated research institutions, with the top-ranked assignee holding 18 of the 200 records in scope. The top five assignees combined hold 32.5% of all records, and the top ten hold 51.0%, out of 83 companies that appear in the full ranking. That leaves a long tail of single- or few-filing entrants below the top tier.
Is patent filing in this space growing or slowing down?
Filing peaked at 26 records in 2021 and fell to 7 by 2024, a 73% decline over that three-year span, which suggests the initial wave of foundational PMU and PDC architecture claims has largely been staked. However, 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so those most recent years should not yet be read as confirming a continued slowdown.
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 Wide Area Measurement and Synchrophasors covering 2015–2026, data cut-off 2026-07-31.
