Ancillary Service Provision from Distributed Assets: Patent Trends
One assignee dominates a thin field. the leader holds 21 records against a fifth-place count of 3, in a ranking of only 10 companies across 51 total records. Filings rose to a peak of 14 in 2023 before falling to 0 by 2024, a -100% move over the 2021-to-2024 span. Because publication trails filing by roughly 18 months, 2025 and 2026 figures are not yet a reliable read on current activity and should not be treated as a continued decline.

Common questions on this landscape
Who holds the most patents in ancillary service provision from distributed assets?
One assignee leads the ranked field with 21 records, well ahead of the fifth-place company's 3, inside a ranking that covers only 10 companies across the full 51-record dataset. That gap is a strong filing-density signal but does not by itself prove market dominance in deployed systems. Smaller filers, including individual inventors, still hold positions in the ranking, indicating the field has not consolidated to a single corporate player.
Is patent filing in this area growing or shrinking?
Filings peaked in 2023 at 14 records, then fell to 0 by 2024, a -100% move over that three-year window. Because publication typically lags filing by around 18 months, the 2025 and 2026 figures are still incomplete and should not be read as confirmation of a real slowdown. The honest read is a confirmed 2023 peak followed by a gap that later filings may or may not fill in once fully published.
Which technology areas are most contested in this patent landscape?
H02J, covering power supply and grid systems, appears in 92.2% of the 51 records in scope, making grid-interface control logic the most heavily claimed area by a wide margin. F03D wind-turbine classifications follow at 31.4%. Battery cells (H01M), EV propulsion (B60L) and gas-turbine plants (F02C) each sit under 8%, marking them as comparatively open relative to the grid-systems layer.
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.
