Vertical-Axis Wind Turbine for EV Charging Patent Landscape
Vertical-Axis Wind Turbine for EV Charging Patent Landscape in 2026
The vertical-axis wind turbine (VAWT) for EV charging space comprises 35 patent families and is in a Growth stage, with filings accelerating sharply on a multi-year basis. A single applicant, Mountain N Meadow Holdings, commands a dominant share, and India leads all filing jurisdictions — signaling an early-stage, geographically concentrated field with room for new entrants.
Mountain N Meadow Holdings leads a heavily concentrated, nascent field
Mountain N Meadow Holdings holds the top position in applicant rankings, followed by Lee Sang Cheol and Bharat Petroleum Corporation Limited. The field’s concentration is pronounced: the top five filers account for 43% of the hundred largest filers’ combined total.
There is a visible tier gap between the lead applicant and the rest of the field. Mountain N Meadow Holdings holds roughly 2.5 times the patent records of the second-ranked applicant, and the majority of named applicants hold only a single patent record each — indicating the field has not yet attracted a broad, competing peer group of portfolio builders.

The leader’s position, built on a combination of wind turbine mechanics (F03D), drone-related integration (B64U), and mechanical fastening elements (E05C), suggests a product-integration strategy rather than pure turbine IP. This leaves core wind energy conversion and EV-specific power delivery pathways comparatively open.
Note that the most recent 18–24 months of filings are under-counted due to publication lag; the apparent plateau in very recent periods should not be interpreted as a slowdown. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity surged from 2022 onward; wind turbine mechanics dominate the technology mix
Two charts together capture the pace and shape of innovation: annual filing activity shows when competitive attention arrived, while the IPC branch distribution shows which technology layers have received coverage and which remain sparse.
Annual filing trend
Filings were negligible from 2017 through 2021, then jumped in 2022 and reached a recorded peak in 2024. The sharp recent-window growth of 633% confirms this is a field in active expansion. Data for 2025 and 2026 are incomplete due to publication lag and will grow as records publish.

F03D (wind motors/turbines) is by far the dominant IPC branch, consistent with a turbine-focused corpus. Secondary branches — H02S (solar/photovoltaic), B64U (drones), E05C (bolts and door fastenings), G07C (time/attendance and checking devices), and H04W (wireless communications) — reflect integration of hybrid energy, structural, and connectivity features. Core EV-side branches such as B60L (electric vehicle propulsion) and H02J (power supply and grid systems) appear at lower counts, pointing to a coverage gap in the power delivery and grid-interface layers.

What the competitive structure means for R&D investment decisions
Three structural features — early growth stage, high concentration at the top, and an India-dominant jurisdiction profile — define the investment context. Each has direct implications for where to build IP and how to position.
Early Growth: window is open for foundational IP
The lifecycle is classified as Growth, with annual filings still rising and the most recent years understated by publication lag. With only 35 patent families in scope globally, foundational claims in core sub-systems remain available. Early movers can still stake broad positions in areas like direct turbine-to-charger power conversion and VAWT rotor optimization for low urban wind speeds.
Growth stageOne dominant portfolio holder; the tier below is fragmented
The top five filers hold 43% of the hundred largest filers’ combined total, with a pronounced gap between rank one and the rest. Most applicants hold a single patent record, indicating the field has not yet attracted deep portfolio competition. A challenger with consistent annual filings across two or three IPC sub-classes could rapidly displace current second-tier players.
High concentrationNo co-applicant activity detected
Evidence of co-filing partnerships is absent from the current dataset. Given the cross-disciplinary nature of the technology — spanning wind mechanics, EV power electronics, and station infrastructure — the absence of collaboration is notable. It may reflect the field’s pre-commercial stage or a preference for sole-inventor filings among the academic and small-company applicants that make up the majority of the ranking.
Evidence pendingIndia dominates filings; PCT and US offer broader protection pathways
India leads all jurisdictions, consistent with the large proportion of Indian academic and institutional applicants in the ranking. The United States, WIPO PCT, Canada, and Europe each show smaller but meaningful filing counts. For applicants targeting commercial deployment in developed EV markets, PCT and US prosecution pathways remain relatively sparse and strategically accessible.

Mountain N Meadow Holdings leads; Lee Sang Cheol and Bharat Petroleum are the nearest challengers
Both top-ranked players entered recently and are classified as new entrants, reflecting the field’s short commercial history. Their technology emphases diverge meaningfully, suggesting different product strategies.
Mountain N Meadow Holdings
Mountain N Meadow Holdings holds 10 patent records, more than double the nearest rival. Its technology focus spans B64U (unmanned aerial vehicles/drones), F03D (wind turbine mechanics), and E05C (bolts and door fastenings), suggesting a system-integration or multi-platform deployment approach rather than a pure wind energy strategy. The applicant is classified as a new entrant with an upward momentum trend, meaning its portfolio was built entirely within the recent filing window.
patent records: 10Lee Sang Cheol
Lee Sang Cheol (appearing in the ranking under two name variants) has focused exclusively on F03D sub-classes covering wind turbine rotor design (F03D 3) and control systems (F03D 7), a tighter and more technically coherent portfolio than the leader’s. Also classified as a new entrant with upward momentum, this applicant represents the closest specialist challenger in core turbine technology.

Under-served branches in power delivery, grid integration, and smart charging
Several IPC branches appear in the corpus at low counts relative to the dominant F03D class, indicating areas where VAWT-for-EV-charging applications exist but have not attracted sustained patenting. These are observations of relative sparsity; technical and commercial value varies by branch.
H02J · Power Supply & Grid Systems
H02J appears at a low count in the corpus, despite being the natural home for claims on DC bus architecture, bidirectional charging, vehicle-to-grid (V2G) interfaces, and energy storage buffering between the turbine and the EV charger. Given that power conditioning is a core engineering challenge in any wind-to-EV system, the sparse coverage here represents a plausible filing target for applicants with power electronics expertise. Entry would likely require differentiated claims around low-wind intermittency management and charger-side power quality.
Search this in Eureka →B60L · Electric Vehicle Propulsion
B60L, which covers EV propulsion systems and on-board charging, appears at a low count in the dataset. Claims at the intersection of B60L and F03D — for instance, dynamic charging protocols adapted to variable wind-sourced power input — remain largely unclaimed. This is an adjacent branch with plausible technical value for applicants working on integrated charging station hardware or software, though the small overall corpus means any new filing in this area would immediately become material to the landscape.

Frequently asked questions
The current dataset contains 35 patent families in scope globally. This is a small, early-stage corpus consistent with a technology that has only recently attracted sustained commercial interest, with the bulk of filings concentrated from 2022 onward.
Mountain N Meadow Holdings leads the applicant ranking with 10 patent records, more than double the count of the second-ranked applicant. It is classified as a new entrant, meaning its portfolio was built entirely within the recent filing window.
India is the leading jurisdiction, reflecting the large share of Indian academic institutions and individual inventors in the corpus. The United States, WIPO PCT, Canada, and Europe each show smaller filing counts. PCT filings offer the broadest protection pathway for applicants targeting multiple markets.
The field is in a Growth lifecycle stage. Recent-window growth stands at 633% versus the prior comparable period. Annual filings peaked in the recorded data at 2024, with 2025 and 2026 data still accumulating due to publication lag. This growth should not be interpreted as near-term saturation.
Yes. IPC branches covering power supply and grid systems (H02J) and electric vehicle propulsion (B60L) appear at low counts relative to the dominant wind turbine (F03D) class. Wireless communications (H04W) and station management (G07C) are also sparsely covered, suggesting that the system-integration and smart-charging layers of VAWT-for-EV-charging remain largely unpatented.
No co-applicant filing activity is present in the current evidence. The corpus is dominated by sole applicants — including individual inventors and academic institutions — which is consistent with an early-stage field that has not yet seen joint development agreements or industry-academia consortia translate into co-filed patents.
