Power Quality Monitoring Patents: Who Leads, Where Filing Cooled 2026
Power Quality Monitoring and Standards Patents
Filing peaked in 2017 at 12 records and has not returned to that level since; 2021's 7 filings fell to 2 by 2024, a 71% drop over that span. Filings peaked at 12 in 2017. By 2021 annual filings had fallen to 7, and by 2024 — the most recent year complete enough to read reliably, given the roughly 18-month lag between filing and publication — to 2, a 71% drop over that three-year window. Years after 2024 will fill in as publications catch up and should not yet be read as a continuing decline.

Common questions about this landscape
Who holds the most patents in power quality monitoring?
One assignee leads this dataset with 15 records, well ahead of the fifth-ranked assignee at 8 and the tenth-ranked at 4. The ranking covers 25 companies in total, drawn from the same 74-record dataset, so it should be read as a full but modest-sized field rather than a top-50 or top-100 cut. The gap between the leader and the rest suggests one company has invested more consistently in this specific claim area than any single competitor, though the long tail shows the field is not closed to new entrants.
Is patent filing in power quality monitoring growing or shrinking?
Filing peaked in 2017 at 12 records and has since declined over a measurable window: from 7 filings in 2021 to 2 in 2024, a 71% drop. Because publication typically lags filing by around 18 months, years from 2025 onward are still incomplete and should not yet be read as continuing the decline. The safest reading is that the field had an early wave of activity that has not been repeated at the same intensity since.
What patent classes dominate power quality monitoring filings?
Electric and magnetic measurement (G01R) appears in 60.8% of the 74 records in scope, making it by far the densest classification. Power supply and grid systems (H02J) follows at 25.7%, with business/data-processing (G06Q), digital transmission (H04L) and wireless networks (H04W) each near or above 10%. Because a record can carry multiple classes, these shares add up to more than 100%, and they describe where filing activity clusters rather than where it is capped.
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 Power Quality Monitoring and Standards covering 2015–2026, data cut-off 2026-07-31.
