Microgrid Protection Coordination Patents: Who Leads, Where the Gaps Are 2026
Microgrid Protection Coordination Patents: Mapping Who Holds the Claims
63.6% concentration. The top 5 of 49 ranked assignees hold 35 of the 55 records in scope — a small group has already staked out most of the filed claim space. Filings rose from 3 records in 2017 to a peak of 6 in 2021, then fell to 2 by 2024 — a -67% move over that three-year window. Because publication trails filing by roughly 18 months, the 2025 and 2026 counts are still incomplete and should not be read as a continued decline.

Common questions on microgrid protection patents
Who holds the most patents in microgrid protection coordination?
The assignee ranking for this dataset covers 49 companies and individuals, and the leader holds 12 of the 55 records in scope, well ahead of fifth place at 4. The top 5 assignees together account for 63.6% of all records, so filing activity is concentrated rather than evenly spread. Anyone assessing competitive position in this space should look closely at that leader’s specific claim scope before assuming open ground.
Is microgrid protection patent filing growing or slowing down?
Filings peaked at 6 records in 2021 and had fallen to 2 by 2024, a -67% change over that span. Because patent publication typically lags filing by around 18 months, the 2025 and 2026 figures in this dataset are still incomplete and should not be read as confirmation of a continued slowdown. The honest read is that the field’s most active filing period has passed, with the current trajectory still unclear.
What patent classes cover adaptive protection and islanding detection?
H02H (protective circuit arrangements) and H02J (power supply and grid systems) are the two dominant classes, each appearing in roughly half of the 55 records in scope. G01R (electric and magnetic measurement) appears in 21.8% of records, covering the sensing side of adaptive schemes, while G05B and G05D cover the control-logic layer at smaller shares. A given filing typically carries several of these classes at once, which is why the shares add up to more than 100%.
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 Microgrid Protection Coordination 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.
