Run your analysis now →Filing growth compares 2021 (13 records) with 2024 (12) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 169 records in scope (CR5), not by the ranked leaders only.
This landscape tracks 169 published records filed against microgrid energy-management optimization, distributed energy scheduling and dispatch control, spanning 2015 through the 2026-07-31 cut-off. The search combines microgrid-specific management terms with system-architecture terms, so the corpus captures control and scheduling claims made specifically inside a microgrid or islandable power-system context rather than generic grid-optimization filings.
Filing offices skew heavily toward China and the United States, with India, WIPO/PCT, Canada and the EPO forming a smaller but active secondary tier. That office mix, combined with an IPC profile still centred on H02J power-supply and grid-systems classification, points to a technology still argued primarily as electrical engineering — even as G06Q-classified scheduling and commerce-adjacent claims take a growing share.
Pick a task. Every answer cites the patents behind it.
Two views of the same 169-record corpus: the year-by-year filing curve, and the IPC subclasses that carry the claim density.
Filings rose from 5 in 2017 to a peak of 18 in 2025. Growth from 2021 (13) to 2024 (12) — the most recent year that can be treated as complete — reads as -8%; 2025 and 2026 counts will keep revising upward as later-filed applications publish.
H02J (power supply & grid systems) appears in 75.1% of records and G06Q (business/commerce data processing) in 30.2%, confirming that most claims are still framed as power-systems control with a substantial scheduling/optimization-data layer on top. G05B control systems (16.0%) and the AI/data-processing classes G06F and G06N (9.5% each) mark where algorithmic claims are concentrating; G05D at 2.4% is the thinnest-claimed class in scope.
Shares are the percentage of the 169 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Try EurekaAn energy management system for microgrid systems. The controller receives forecasted weather condition data, predicts a power generation and/or demand profile of the microgrid in response, determines a performance and/or degradation model of one or more system components from that profile, derives an energy management optimization strategy from the performance/degradation model, and controls the microgrid accordingly.Abstract condensed from the published filing for length; full claim language governs scope.

Citation counts favour older records simply by virtue of having had more time to accumulate citations inside this searched corpus; read them as a signal of influence on the field's early framing, not of current technical importance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

The single leader holds 14 records and the fifth-ranked assignee only 6 — the drop-off from first to fifth is steep, but the top 5 still account for just 27.8% of all 169 records in scope. The top 10 combined reach 40.2%, meaning well over half the corpus sits with a long tail of single- or few-filing entrants.
H02J's 75.1% share dwarfs every other class, and G06Q at 30.2% is the only other class above 20%. The AI-flagged classes G06F and G06N each sit at just 9.5%, suggesting most claims still ground optimization logic in power-systems terms rather than filing it as a standalone AI method.
2025 is the peak year on record at 18 filings, but publication lags filing by roughly 18 months, so 2025 and 2026 totals will both rise as more applications publish. The only span safe to describe as a trend is 2021 to 2024, where the count moved from 13 to 12 — an -8% change, essentially flat rather than declining.
Ten co-assignee pairs appear in the corpus, with the strongest links running through a small cluster of Chinese state-grid-affiliated entities filing together on the same records. Outside that cluster, co-filing is sparse, which matches a field where a long tail of entrants files independently.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to microgrids — microgrid energy-management optimization patent landscape, with the prior art for and against each one.
The ranking behind this page covers 100 companies, counted in records — not a top-50 or top-100 cut, but the full set the data endpoint returns.
The top-ranked assignee holds 14 records against a fifth-place count of 6 and a tenth-place count of 3 — a real gap at the very top that flattens quickly once you move past the first few names.
With the top 10 at 40.2% of 169 records, roughly three-fifths of the corpus is spread across assignees filing only a handful of records each — a structure that rewards a freedom-to-operate search over any assumption of a settled dominant-player landscape.
Several of the assignees with the largest historical counts — including some of the top-ranked filers — show zero filings in the latest year tracked. That does not mean they have exited; it is consistent with publication lag, but it also means recent momentum in this field is not concentrated with the historical leaders.

The ranking, IPC breakdown and most-cited table on this page are a starting point for scoping, not a substitute for a full freedom-to-operate or novelty check.
Cross-check the under-claimed sub-areas above against your own architecture before drafting, especially where control logic touches degradation modelling or islanding transitions.

Pull full-text claims in Eureka →This dataset covers 169 published records classified against microgrid energy-management optimization, distributed energy scheduling and dispatch control terms, filed between 2015 and the 2026-07-31 cut-off. The true current total is higher than the recent-year counts suggest, because publication typically lags filing by around 18 months, so 2025 and 2026 figures will keep rising as more applications publish. Use the 169-record figure and its filing-year breakdown as a scoped snapshot rather than an exhaustive global count.
The ranking behind this page covers 100 companies, counted in records, with the top-ranked assignee holding 14 records and the top 5 combined accounting for 27.8% of all 169 records in scope. That leaves a substantial long tail: the top 10 together reach only 40.2%, so most of the field is held by assignees with a handful of filings each rather than a small dominant group. Several of the largest historical filers show zero filings in the most recent tracked year, which may reflect publication lag rather than an actual pullback.
The dominant IPC subclass is H02J, power supply and grid systems, appearing in 75.1% of the 169 records in scope. G06Q, covering business and commerce data processing, is the next largest at 30.2%, reflecting the scheduling and optimization-data side of the technology. G05B control systems, G06F and G06N data-processing/AI classes, G05F variable control, H04L transmission and G05D non-electric control round out the composition, each at a smaller but non-trivial share; because records can carry multiple classes, these shares add up to more than 100%.
Filings rose from 5 in 2017 to a peak of 18 in 2025, but the only span that can be read reliably as a trend is 2021 to 2024, where the count moved from 13 to 12 — a -8% change, essentially flat. Figures for 2025 and 2026 are still incomplete because of publication lag, typically around 18 months from filing to publication, so they should not be read as a slowdown. Treat the most recent two years as provisional until later publications catch up.
The thinnest-claimed IPC class in this corpus is G05D, non-electric variable control, at just 2.4% of 169 records, alongside modest shares for AI-flagged classes G06F and G06N at 9.5% each. That points to under-claimed ground in degradation-aware dispatch modelling, weather-forecast-driven generation profiling, islanding-mode transition control, and AI-native scheduling logic claimed outside the dominant G06Q framing. Any of these branches is worth a dedicated novelty search before drafting, since low record counts here reflect thinner prior art rather than lack of technical relevance.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
