Wireless EV Charging for Airport Ground Support Patent Landscape
Wireless EV charging for airport ground support equipment is a nascent, essentially uncontested space: only 2 patent families exist in scope, both filed in India by academic institutions in 2024–2025. The field presents a wide-open opportunity for industrial and aerospace-sector players willing to establish early prior art.
Two academic filers hold the entire known patent footprint
The visible assignee structure is entirely pre-commercial: Ecole Centrale School of Engineering at Mahindra University and Francis Xavier Engineering College each hold 1 patent family, together accounting for all activity captured in this topic.
Concentration among the top hundred ranked filers is, by definition, absolute — the two academic institutions share 100% of the top-ranked filers’ combined total, with no industrial or airport-operator assignee present.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Ecole Centrale School of Engineering, Mahindra University | 1 | |
| 2 | Francis Xavier Engineering College | 1 |
The absence of established EV manufacturers, airport ground-handling companies, or wireless-power specialists from the applicant list signals that this application space has not yet attracted serious commercial patenting attention.
Activity is restricted to a single jurisdiction (India), and the two filings appeared only in 2024 and 2025; additional records may still be pending publication given standard 18-month lag. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
First filings emerged in 2024; technology mix centres on EV propulsion and power supply
The annual filing trend and technology composition together paint a picture of a field at its very earliest stage, with no filing activity before 2024 and a narrow but coherent IPC footprint.
Annual filing trend
Zero filings appear across 2017–2023; one family was filed in each of 2024 and 2025, and 2026 shows zero — consistent with publication lag rather than a halt in activity. No trend can yet be inferred from two data points.

All 2 patent families span three IPC classes — B60L (electric vehicle propulsion), H02J (power supply and grid systems), and H02M (power conversion) — each appearing twice, reflecting the inherently cross-disciplinary nature of wireless charging for mobile ground equipment.

A wireless electric vehicle charging protocol
A wireless charging protocol for electric vehicles (EVs) by using resonant inductive coupling and optimizing coil designs, that achieve high efficiency even in suboptimal conditions. The present charging protocol employ a dynamic charging mechanism that allow charging while the vehicle is moving, reducing the dependence on perfect alignment of the vehicle… (excerpt from the patent abstract)

What the structure means for R&D investment decisions
With only 2 patent families filed by academic institutions in a single jurisdiction, every structural signal points to an embryonic field where industrial entrants can define the IP landscape rather than navigate one already established.
Embryonic — no life-cycle stage determinable
The evidence base is too small to assign a formal life-cycle stage. First filings appeared only in 2024–2025, exclusively from engineering schools. There is no evidence of replication, citation networks, or commercial follow-on, placing this firmly in a pre-growth phase.
Pre-growthTwo academic institutions hold all known families
Ecole Centrale School of Engineering at Mahindra University and Francis Xavier Engineering College each hold 1 patent family. No industrial assignee — EV OEM, wireless-power supplier, or airport operator — appears in the ranking. The top five filers’ share of the ranked applicants visible in this query stands at 100%, reflecting an entirely un-commercialised IP pool.
NascentNo co-applicant activity detected
Evidence pending. No co-filing relationships appear in the dataset. Given that both current filers are academic institutions, future industry–academia collaborations could accelerate IP development and add commercial relevance to the growing body of foundational research.
Evidence pendingAll activity confined to India
Both patent families were filed through the Indian patent office, and no equivalent filings appear in PCT, EPO, USPTO, or other major jurisdictions. This leaves the field entirely open for first-mover filing in every major EV and aviation market outside India.

Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Ecole Centrale School of Engineering, Mahindra University
Holds 1 patent family, filed in 2024–2025, with IPC emphasis on B60L 53 (EV charging methods), H02J 50 (wireless power transfer), and H02J 7 (battery charging circuits). Applicant momentum is flagged as a new entrant, consistent with a single recent filing from a small prior base.
families: 1Francis Xavier Engineering College
Holds 1 patent family with IPC focus on B60L 53, B60L 55, and H02J 50, indicating interest in both the vehicle-side propulsion interface and the power-supply infrastructure for wireless charging. No momentum trend is separately reported for this filer in the current evidence window.
families: 1Frequently asked questions
The evidence contains 2 patent families in scope, both filed in India by academic institutions in 2024 and 2025.
Ecole Centrale School of Engineering at Mahindra University and Francis Xavier Engineering College each hold 1 patent family. No industrial assignee appears in the current evidence.
All 2 patent records are filed in India. No filings appear in PCT, EPO, USPTO, or other jurisdictions, leaving those markets entirely open.
The filings span three IPC classes: B60L (electric vehicle propulsion), H02J (power supply and grid systems), and H02M (power conversion), each appearing in both families.
The first filings appeared in 2024 and 2025. No activity was recorded between 2017 and 2023. The 2026 figure of zero is consistent with publication lag and does not indicate a halt.
Based on the evidence, the field is entirely pre-commercial with only academic prior art in a single jurisdiction. Industrial filers in EV manufacturing, wireless power, or airport operations would face minimal existing prior art in major markets, making early IP establishment technically and strategically feasible — though a company’s specific claims would need to be assessed against the 2 known Indian families.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
