Wind Resource Assessment Patents: Top Companies & Trends 2026
- Concentrated at the top. The five leading assignees account for 99 of 386 records in scope (25.6%), and the top ten hold 39.9% — a dense core with a long tail below it.
- Filing activity nearly tripled. Filings rose from 8 in 2021 to 21 in 2024, a +163% increase over that span, before 2025's partial count of 35 (still filling in).
- Software is catching up with hardware. F03D (wind turbines) leads at 36.0% of records, but G06F (data processing) sits close behind at 29.0%, ahead of H02J grid systems at 22.0%.
Filing growth compares 2021 (8 records) with 2024 (21) — 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 386 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape maps 386 published records at the intersection of wind resource assessment, wind forecasting and the physical parameters that condition turbine operation — wind speed, rotor torque, process temperature and related measurement or control variables. The scope spans both the meteorological side of the field (site assessment, short-term forecasting) and the turbine-control side (torque and load response to forecast or measured wind conditions), which is why the technology composition spreads across turbine hardware classes and data-processing classes rather than sitting in one place.
Filing has been uneven rather than steadily rising: growth from 2021 to 2024 was sharp, and the most recent one to two years should be read as undercounted because publication typically lags filing by around 18 months. The assignee base blends established turbine OEMs, grid and power-electronics suppliers, meteorological technology firms and a scatter of single-filing entrants — a structure that rewards checking both the concentrated core and the tail before deciding where to file.

Filing trends and technology composition
Two views of the same 386-record dataset: how filing volume has moved year over year, and how records distribute across the IPC subclasses that define the technology.
Filing trend, 2017–2026
Annual filings moved from 17 in 2017 to a peak of 35 in 2025, with the 2021-to-2024 span showing the clearest sustained growth (+163%). The 2026 figure of 9 is a partial year and the 2025 peak itself is still subject to upward revision as later publications land.
IPC subclass distribution
F03D (wind motors/turbines) and G06F (digital data processing) are the two largest classes, each covering roughly a third to just under a third of records, with H02J (power supply and grid systems), G01W (meteorology) and G06Q (business/admin data processing) each present in a meaningful minority. Because records often carry multiple classes, these shares sum to well over 100% of the 386-record total — that overlap itself signals how much of this field sits at the junction of turbine hardware, grid integration and computational forecasting rather than in a single discipline.
Shares are the percentage of the 386 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US10879702B2 — System and method for performing wind forecasting
A system and method for performing wind forecasting that is particularly accurate over short-term time periods, e.g. the next 1-5 hours. The method is anchored in a physical model of wind variability in the atmospheric boundary layer, using the unsteady dynamics of the atmosphere to drive forecasting as a function of previously observed atmospheric condition data at the same location.Filed by Trustees of Princeton University, published 2020-12-29 — an academic filing built on a physical atmospheric-boundary-layer model rather than a purely statistical or machine-learning approach.

Reading the concentration, growth and technology-mix figures together points to a field where filing has accelerated recently but not yet consolidated around a dominant approach.
A dense core, then a long tail
The leading assignee holds 26 records and the field narrows quickly after that — fifth place sits at 13, tenth at 9. Combined, the top five hold 25.6% of all 386 records and the top ten hold 39.9%, meaning well over half of filings sit outside the ranked leaders entirely.
Sharp acceleration, not a slow build
Filings moved from 8 in 2021 to 21 in 2024 — a +163% increase in three years, the clearest growth signal in the dataset. The 2025 count of 35 looks like a continuation of that trend, but with publication lag it is still an incomplete picture.
Hardware still leads, software is close behind
F03D (wind turbine motors) covers 36.0% of the 386 records, but G06F (digital data processing) is close at 29.0%, with G06N (AI-based computing) present in 7.8% — evidence that forecasting and control software is becoming as central to new filings as turbine hardware itself.
US and China lead filing venues
The United States (102) and China (67) are the two largest receiving offices, ahead of the EPO (61), WIPO/PCT (33), India (30) and Germany (16) — a spread that suggests applicants are pursuing protection across multiple major markets rather than concentrating on one jurisdiction.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to wind resource assessment & forecasting patent landscape, with the prior art for and against each one.
Who is active, and where momentum sits
The ranked leaders span turbine OEMs, grid-equipment suppliers and meteorological technology providers, but the most recent-year momentum figures show the named leaders at zero new filings in the latest year — a sign the field's growth is coming from outside the current top ranks, or that recent filings have not yet published.
A single leader, not a runaway one
The top-ranked assignee holds 26 of the 386 records in scope, roughly double the fifth-place count of 13 — a real lead, but not one that forecloses the field for others.
Named leaders show no latest-year filings
Every leading assignee tracked for recent-year momentum shows 0 filings in the latest year, including one with a -100% year-on-year change. Given the roughly 18-month publication lag, this most likely reflects filings still in the pipeline rather than an actual pullback.
Limited but real co-filing activity
Nine co-assignee pairs appear in the data, with the strongest pairings repeating across three to four shared records — evidence of a small number of stable inventor-assignee collaborations rather than broad industry co-filing.

Where to take this next
The dataset points to specific follow-up questions rather than a single conclusion — use these to decide where deeper diligence is warranted.
Check the software overlap classes
With G06F at 29.0% and G06N at 7.8% of records, forecasting algorithms are a growing share of new filings. Anyone entering this space should map claim language in these classes separately from turbine-hardware claims.
Explore technology classes in EurekaWatch the tail, not just the leaders
With 39.9% of records held by the top ten and 60.1% spread across the rest, a competitor worth tracking may not yet appear near the top of the ranking.

Publication lag means the most recent two years of data are undercounted; re-checking the trend in six to twelve months will sharpen the read on whether the 2021-2024 growth rate has continued.

The top-ranked assignee in this dataset holds 26 of 386 records in scope, with the field dropping off gradually after that — fifth place holds 13 and tenth holds 9. Combined, the top five assignees account for 25.6% of all records and the top ten account for 39.9%, meaning most of the field's filings sit outside the ranked leaders. This pattern is typical of a technology area with an established core of turbine OEMs and grid suppliers alongside a long tail of research institutions and single-filing entrants.
Filings grew sharply from 8 in 2021 to 21 in 2024, a +163% increase over three years, which is the clearest and most reliable growth signal in this dataset. Figures for 2025 and 2026 appear lower or partial, but that reflects publication lag of roughly 18 months rather than an actual slowdown — recent filings simply have not all published yet. Any read on the very latest years should treat the counts as a floor rather than a final figure.
Turbine hardware (IPC class F03D) is the single largest category at 36.0% of the 386 records, but digital data processing (G06F) is close behind at 29.0%, followed by power/grid systems (H02J) at 22.0% and meteorology (G01W) at 15.3%. Because a single patent can carry several IPC classes, these shares add up to more than 100% of the record total — the overlap itself shows how much of the field spans turbine control, grid integration and computational forecasting simultaneously. AI-based computing (G06N) appears in a smaller but notable 7.8% of records, suggesting machine-learning approaches are an emerging rather than dominant thread.
The technology composition data suggests the overlap between meteorology (G01W, 15.3%), velocity/acceleration sensing (G01P, 10.1%) and AI-based computing (G06N, 7.8%) is comparatively thin next to the dominant F03D and G06F classes, which points to short-term ramp forecasting and physically-grounded boundary-layer modelling as areas with room to file. The long tail below the top ten ranked assignees, who together hold only 39.9% of records, also indicates that no single company has locked down adjacent branches like rotor-torque response to forecast conditions. Any white-space assessment should be paired with a full claims review, since IPC class presence indicates activity, not necessarily claim breadth.
US10879702B2, assigned to the Trustees of Princeton University and published in December 2020, covers a short-term wind forecasting method anchored in a physical model of atmospheric boundary-layer dynamics rather than a purely statistical or machine-learning approach. Anyone building a forecasting system that models unsteady atmospheric dynamics to predict wind conditions one to five hours ahead using prior observations at the same location should review this filing's claims closely. It does not appear among the most-cited records in this dataset, so its influence should be weighed against the more heavily cited commercial-value-optimisation family rather than treated as the field's dominant reference.
