Distributed Generation Hosting Capacity Patents: Leader & Long Tail 2026
Distributed Generation Hosting Capacity Patents: Who Holds the Feeder-Level Claims
71.7% concentration. The top five assignees hold 33 of the 46 records in scope — a field with a clear leader rather than a scattered field of equal filers. Filings were negligible before 2021 (2 that year), climbed to a peak of 11 in 2023, and grew from 2 to 4 records between 2021 and 2024 — a +100% rise over that span. Later years are undercounted due to publication lag, not falling interest.

Frequently asked questions
What does “hosting capacity” mean in a patent context?
In this dataset, hosting capacity refers to inventions that quantify or manage how much distributed generation — typically rooftop solar or storage — a distribution feeder can accept before voltage, thermal or protection limits are breached. Claims in this space usually pair a hosting-capacity assessment method with a mitigation mechanism such as reverse power flow control, tap-changer operation, smart inverter functions or curtailment allocation. The representative filing in this set, US20200091765A1, assesses hosting capacity on a feeder-by-feeder basis by testing randomly selected spot load points against system performance limits.
Who are the leading patent filers in distributed generation hosting capacity?
The ranked list covers 24 companies, and it is heavily front-loaded: the top five assignees together hold 33 of the 46 records in scope, or 71.7%, and the top ten account for all 46 records. The leading single assignee holds 9 records, well ahead of fifth place at 5 and tenth place at 2. That pattern means most of the claim space traces to a small group of utilities, technology vendors and one university, rather than being spread across many independent filers.
Is patent filing activity in this area growing or slowing down?
Filing activity grew from 2 records in 2021 to 4 in 2024, a rise of 100% over that span, with the peak year so far at 2023 with 11 records. It is not accurate to describe the field as slowing based on 2025-2026 counts, because patent publication typically lags the actual filing date by around 18 months — the most recent one to two years in any patent trend are always undercounted until later data catches up.
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 Distributed Generation Hosting Capacity covering 2015–2026, data cut-off 2026-07-31.
