Storage Dispatch Patents: Who Leads, Where the Gaps Are 2026
- 38.8% of all 103 records sit with just five assignees, but the ranked list runs 64 companies deep — concentration at the top with a long tail below it.
- Filings grew 67% from 2021 to 2024 (6 to 10 records), with 2022 the peak year so far at 19 published records.
- G01R measurement and H02J grid/power-supply classes dominate at 66.0% and 48.5% of records respectively, while AI-based computing (G06N) sits at just 9.7% — a comparatively thin claim base for learned health models.
Filing growth compares 2021 (6 records) with 2024 (10) — 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 103 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape tracks patent activity at the intersection of storage dispatch optimisation and degradation-aware battery control — filings that combine dispatch, cycle counting or calendar-aging logic with state-of-health estimation, depth-of-discharge management or throughput limits. The scope spans 2015 through the 2026-07-31 data cut-off, capturing both the utility-scale grid storage side (microgrid dispatch, energy arbitrage scheduling) and the vehicle and cell-level side (battery health estimation, swelling-based state of health).
The 103 records in scope are drawn from filings where dispatch or scheduling logic is claimed together with a degradation or aging model, rather than treated as two separate technologies. That intersection is deliberately narrow: it excludes pure battery-chemistry patents and pure grid-scheduling patents that make no reference to health or aging constraints.
Publication lags filing by roughly 18 months, so counts for 2025 and 2026 will keep rising as later filings publish — read the most recent two years as a floor, not a ceiling.

Pick a task. Every answer cites the patents behind it.
Filing trend and technology composition
Two views of the same 103-record corpus: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
Filing trend, 2017–2026
Filings rose from zero in 2017 to a peak of 19 in 2022, then continued at a materially higher base than the pre-2020 years; 2021 to 2024 alone shows +67% growth (6 to 10 records). The 2025-2026 figures will revise upward as publication catches up with filing.
IPC subclass composition
G01R (electric and magnetic measurement) appears in 66.0% of the 103 records and H02J (power supply and grid systems) in 48.5%, confirming that most filings anchor their claims in measurement or grid-interaction hardware rather than software alone. H01M (batteries and cells, 34.0%) and B60L (EV propulsion, 32.0%) show the vehicle and cell-level side is nearly as active as the grid side. Classes tied to computation — G06N, G06F, G06Q — each sit under 10%, meaning algorithmic or data-processing claims are comparatively rare relative to the electrical and measurement claims that surround them.
Shares are the percentage of the 103 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

State of battery health estimation based on swelling characteristics
Filed by The Regents of the University of Michigan, this family discloses a battery management system that uses a pressure sensor to capture a non-electrical, mechanical force signal from the cell and combines it with incremental capacity analysis to estimate state of health. The controller selects an incremental-capacity curve based on the force measurement, aiming for better precision on capacity fading than electrical-signal-only methods.Related family members (WO2017087807A1 and US20210197691A1) are both among the most-cited records in this corpus.

Citation counts are drawn from a searched corpus and skew toward older filings that have had more years to accumulate citations — read them as a signal of influence within this dataset, 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.

Concentration, growth and claim density each point to a different part of the field worth watching.
Top of the field is thin, the tail is long
The five leading assignees account for 38.8% of all 103 records in scope, while the full ranking runs to 64 companies — most holding a single filing. That combination signals an active but not yet consolidated space: no single player has cornered dispatch-plus-degradation claims outright.
Filing pace stepped up mid-decade
After a slow start pre-2020, filings peaked at 19 in 2022 and the 2021-to-2024 window shows sustained growth rather than a one-year spike. That pace, plus the 18-month publication lag, suggests the true 2025-2026 volume is still understated in the raw counts.
Measurement claims dominate the field
Two-thirds of records touch electric or magnetic measurement (G01R), and nearly half touch grid/power-supply systems (H02J). Filing a dispatch patent that avoids both classes is difficult; most competitive filings will need to differentiate within already-crowded measurement claim space rather than around it.
Swelling-based state of health anchors the field
The most-cited record in the corpus, and two related family members among the top five, all concern swelling-characteristic-based state of health estimation — a mechanical rather than purely electrical measurement approach that has drawn outsized downstream citation.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to storage dispatch and degradation aware control, with the prior art for and against each one.
Who is filing, and where the openings sit
The ranked list covers 64 companies from the data endpoint — not a top-50 or top-100 cut — with filings concentrated at the top and thinning quickly.
One clear leader, no runaway share
The leading assignee holds 12 of the 103 records, with fifth place already down to 6 and tenth place at 3. That gradient is steep near the top but the field never locks up: most of the ranked companies hold only one or two filings each.
Co-filing is rare
Only two co-assignee pairings appear across the corpus, the strongest being a four-record pairing between two individual inventors. Corporate co-assignment is essentially absent, which points to a field still built on solo corporate or academic filing rather than joint ventures.
US and Europe lead receiving offices
The United States receives the largest share of filings (44), followed by the EPO (17) and India (14), with China (10), WIPO/PCT (9) and Germany (4) behind. That spread suggests companies are prioritising US and European protection first, with India emerging as a meaningful secondary market.

Where to take this research
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, sourcing, or claim drafting.
Check freedom-to-operate against the swelling-based SOH family
The most-cited records in this corpus cluster around swelling-characteristic state-of-health estimation. Any filing touching mechanical or pressure-based health signals should be checked against this family specifically, not just against electrical-signal SOH art.
Explore this family in EurekaMap the under-claimed AI and business-logic branches
G06N, G06F and G06Q classes each sit under 10% of records despite the field's reliance on optimisation and forecasting logic. That gap is a plausible drafting opportunity for claims that bridge dispatch scheduling with learned degradation models.
Run a white space search in EurekaTrack the long tail for acquisition or licensing signals
With 64 ranked assignees and most holding only one or two records, single-filing entrants are worth periodic monitoring — a small portfolio in this space can still hold a pivotal measurement or control claim.

In this landscape, a degradation-aware dispatch patent is one that claims dispatch, scheduling or energy-arbitrage logic together with an explicit model of battery aging — such as cycle counting, a calendar-aging model, depth-of-discharge tracking, state-of-health estimation or an energy-throughput limit. Filings that claim dispatch optimisation without any aging constraint, or that claim battery health estimation without any dispatch or scheduling element, fall outside this specific intersection. The 103 records in scope were selected because they combine both elements in the same family.
The ranking covers 64 companies returned by the data endpoint, with the single leading assignee holding 12 of the 103 records and the top five combined accounting for 38.8% of all records in scope. That is meaningful concentration at the very top, but the ranking quickly thins into a long tail of assignees holding only one or two filings each, so no single company controls the field outright. Readers should treat the leader board as a starting point for freedom-to-operate checks rather than a complete map of competitive risk.
Filings grew 67% from 2021 to 2024 (6 records to 10), with a peak of 19 records in the 2022 publication year, indicating sustained rather than one-off growth through the middle of the decade. Counts for 2025 and 2026 appear lower in the raw data, but that reflects the roughly 18-month lag between filing and publication rather than an actual slowdown — those years will revise upward as later filings publish. Any claim that the field is cooling should be checked against this lag before being taken at face value.
Electric and magnetic measurement (G01R) appears in 66.0% of the 103 records and power supply and grid systems (H02J) in 48.5%, making these the most claim-dense areas — new filings here will sit close to existing art. By contrast, AI-based computing (G06N, 9.7%), general digital data processing (G06F, 5.8%) and business/commerce data processing (G06Q, 5.8%) are comparatively thin, suggesting more room for claims that bridge learned degradation models or scheduling logic with dispatch control.
EP3377363A1, filed by The Regents of the University of Michigan, covers a battery management system that estimates state of health using a mechanical pressure signal combined with incremental capacity analysis, rather than relying on electrical signals alone. It and its related family members (including WO2017087807A1 and US20210197691A1) are among the most-cited records in this corpus, indicating the approach is widely referenced by later filers. Anyone developing a swelling- or force-based health estimation method should review this family closely, though electrical-signal-only or purely software-based SOH approaches sit in different claim territory.
