Electricity Transmission Patents: Top Companies & Filing Trends 2026
- 34.0% concentration at the top. The five most active filers account for 198 of 582 records in scope — a distinct lead group rather than a flat field.
- Filing has cooled from its 2017 peak. 57 records published that year against a confirmed -48% drop from 2021 (27) to 2024 (14), the last year the trend can be read as complete.
- H02J dominates, but the field is multidisciplinary. 53.6% of records touch power supply and grid systems, while G06Q business-process filings (16.5%) show dispatch and market logic increasingly patented alongside hardware.
Filing growth compares 2021 (27 records) with 2024 (14) — 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 582 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape maps 582 published records filed against grid frequency, power dispatch, voltage profile, load forecasting, grid control and voltage regulation claims tied to electricity transmission. The scope spans utility-scale grid management systems, demand-response platforms and the control logic that sits between generation forecasts and delivered load — not generation hardware itself. Patent families, rather than raw document counts, are the fairer unit here because family counts neutralise continuation filings and multi-jurisdiction duplicates that would otherwise inflate a single invention’s footprint.
Filing activity peaked in 2017 and has since receded; publication lags filing by roughly 18 months, so the most recent one to two years in any chart will always understate real activity and should not be read as the technology fading.
Filing trend and technology composition
Two views of the same 582-record dataset: how filing volume moved year over year, and which IPC subclasses carry the claim density.
Filing trend, 2017–2026
Filings ran at 57 in 2017, the peak on record, and fell to a confirmed -48% change between 2021 (27) and 2024 (14) — the last year with a complete publication window. Years after 2024 are still filling in as publications catch up to filing dates.
IPC subclass composition
H02J (power supply and grid systems) covers 53.6% of the 582 records, with G05B and G05F control-and-regulation classes each near a fifth of the field. G06Q's 16.5% share signals that dispatch, billing and market-operations logic is being claimed as heavily as the electrical hardware itself; classes overlap, so shares sum past 100%.
Shares are the percentage of the 582 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Method and apparatus for demand management on an electrical grid
The filing describes a power management system that ingests a wind power forecast and a load forecast for an electric grid, classifies time periods by the relationship between the two, and transmits that characterization to a subscriber so consumption timing can be planned against the load plan.Filed by Windeverest Corp., published 2024-12-05 (US20240405550A1).

Four read-throughs from the concentration, trend and classification data above.
A lead group, not a flat field
The top five assignees combined account for 198 of the 582 records in scope, and the top ten extend that to 280 records, or 48.1%. That is meaningful concentration without a single dominant monopolist — the leader holds 54 records against a fifth-place figure of 26, so the gap narrows quickly below the top few.
Cooling from a 2017 peak
Filing volume peaked at 57 records in 2017 and the last fully comparable window shows a confirmed drop from 27 records in 2021 to 14 in 2024. Years beyond 2024 will fill in further as publication catches up, so this should be read as a real but partial cooling rather than a cliff.
Grid hardware still anchors the field
H02J (power supply and grid systems) covers over half of all records, but G05B and G05F control classes each sit near a fifth of the field and G06Q business-process claims reach 16.5%. That spread indicates dispatch and market-operations logic is now a first-class claim target, not an afterthought bolted onto hardware.
Influence sits with early grid-management filings
The most-cited records in this dataset are grid- and asset-management filings from the late 2000s, with citation counts well above newer entries. That pattern is typical of a searched corpus: older filings have had more years to accumulate citations, so high counts mark historical influence rather than current commercial weight.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to electricity transmission patent landscape, with the prior art for and against each one.
Who is filing, and where the gate sits
The ranked leaders hold a real but not overwhelming share of the field, leaving room to assess where a new entrant would actually compete for claim space.
A clear leader without a monopoly
The top-ranked assignee holds 54 of 582 records, roughly double the fifth-place figure of 26. That gap suggests one filer built an early, durable position in grid control and demand-management claims rather than the field being contested evenly from the outset.
A fast taper below the top five
By the tenth position, filing counts have dropped to 13 records, less than half the fifth-place count. Combined with the top ten's 48.1% share of all 582 records, this points to a moderately concentrated field with a long tail of smaller filers below it.
Momentum has stalled among named leaders
Several of the assignees tracked for recent-year momentum show no filings in the latest year, consistent with the broader post-2021 cooling. Given publication lag, this is as likely to reflect filings still working through the pipeline as it is a genuine pause in R&D investment.

Where to take this next
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, portfolio positioning or scouting.
Check freedom-to-operate against the lead group
With 34.0% of records held by five assignees, a new filing in core grid-control or voltage-regulation claims will likely sit close to existing prior art from that lead group. Run a claim-by-claim comparison before drafting.

The confirmed -48% drop through 2024 is real, but records filed since then are still publishing. Re-check filing volume in this window before concluding the field has slowed for good.
Track filing trends in EurekaScope claims in the under-claimed branches
Wind-forecast-linked demand classification and cross-jurisdiction voltage-profile work show thinner filing density than core H02J claims, suggesting room for a differentiated first claim.

The ranked leader in this dataset holds 54 of the 582 records in scope, with the top five assignees combined accounting for 198 records, or 34.0% of the field. That is a real concentration at the top, but it tapers quickly: the tenth-ranked assignee holds only 13 records, and the top ten together reach 48.1% of all records. Below that point the field spreads across a long tail of smaller filers, so a new entrant is not up against a single dominant holder across every claim area.
Filing peaked in 2017 at 57 records and the most recent fully comparable window shows a confirmed -48% change, from 27 records in 2021 to 14 in 2024. That is a genuine cooling, not a data artifact, but 2024 is also the last year that can be read as complete. Publication lags filing by roughly 18 months, so 2025 and 2026 figures are still filling in and should not be read as a continued decline until later data confirms it.
H02J, covering power supply and grid systems, appears in 53.6% of the 582 records and anchors the field. Close behind are G05B and G05F, both control-and-regulation classes near a fifth of records each, and G06Q business-process filings at 16.5%, which cover dispatch and market-operations logic layered on top of the grid hardware. Because a single record can carry several IPC classes, these shares add up to more than 100% and should be read individually against the 582-record total, not summed.
Filing density is comparatively thin in areas like wind-forecast-linked demand classification, cross-jurisdiction voltage-profile harmonization, and hybrid dispatch logic that bridges thermal-plant control with grid-control systems. These sit adjacent to the dense H02J and G05B/G05F core rather than replacing it, which is why they show up as gaps rather than as entirely new categories. A first claim there would need to combine an existing grid-control mechanism with the specific under-claimed function to avoid re-treading dense prior art.
The United States leads with 230 records in this dataset, followed by the European Patent Office at 80 and WIPO's PCT route at 65. Australia, India and Canada each sit in the low-to-mid thirties. That distribution suggests the US is the primary battleground for freedom-to-operate checks, with EPO and PCT filings the next most important jurisdictions to clear before broader international rollout.
