Wireless EV Charging for Electric Buses Patent Landscape
The patented corpus for wireless EV charging applied to electric buses is extremely small — only 6 patent families in scope — with Florida International University holding the largest single share and India dominating by filing jurisdiction. The field shows early-stage, fragmented activity concentrated among academic and institutional filers rather than commercial OEMs or tier-one suppliers.
Academic institutions lead a nascent, highly concentrated field
Florida International University ranks first with 2 patent families, accounting for the largest single share among the five filers that collectively make up the entire ranked corpus. The remaining four applicants — Ecole Cent School of Engineering at Mahindra University, Francis Xavier Engineering College, Dr. M. G. R. Educational & Research Institute, and Ballari Institute of Technology & Management — each hold 1 patent family.
The top five applicants together account for 100% of the top hundred filers’ combined total, a concentration figure that reflects how underdeveloped commercial patenting in this specific niche remains. There is effectively no second tier: all filers are at parity except for the leader’s marginal two-family advantage.
| # | Applicant | Patent families | Share |
|---|---|---|---|

| 2 | Ecole Cent School of Engineering at Mahindra University | 1 | |

The dominance of academic and engineering-college applicants signals that foundational research patenting is still ahead of industrial-scale R&D in this space. No automotive OEM, charging-infrastructure operator, or power-electronics specialist appears in the corpus, leaving the field open for commercial entrants.
Filings from 2024–2026 are subject to standard publication lag and likely undercount actual recent activity; the corpus of 6 patent families should be read as a lower bound on current filings. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sporadic filing history with a recent uptick; technology anchored in EV propulsion and power supply
Two charts frame the field’s development: annual filing volume since 2017 reveals whether this is a stable or accelerating niche, while the IPC technology composition shows which engineering branches attract the most coverage.
Annual filing trend
Filing activity opened with 2 families in 2017, then went quiet through 2023, before recovering to 2 families in 2024 and a further 2 in 2025. The zero values across 2018–2023 likely reflect the small absolute size of the corpus rather than a true pause — a single new family would represent a measurable share. The 2025 and 2026 bars should be treated as provisional given publication lag.

B60L (electric vehicle propulsion) and H02J (power supply and grid systems) are tied as the visible IPC classes, each covering all 6 patent records in the corpus. H02M (power conversion, AC/DC) covers 4 records, reflecting the secondary importance of converter topology work. No other IPC branches appear, indicating a tightly focused but narrow technology footprint.

What the structure means for R&D investment decisions
Four structural dimensions — maturity, concentration, collaboration, and geography — shape the risk-reward profile for any entrant considering this space.
Pre-commercial, early research stage
The lifecycle stage is not formally determinable from the evidence, but the corpus profile — 6 total families, all held by universities and engineering colleges, with a dormant mid-period and only a recent tentative uptick — is consistent with a pre-commercial research phase. No incumbent IP thicket exists. An industrial entrant would be building on, not navigating around, established prior art.
Early stageExtreme concentration among academic filers
Five institutions share 6 patent families, and the top five account for 100% of the ranked applicants visible in this query’ combined total. Florida International University leads with 2 families. This degree of concentration at such a small absolute scale means the field lacks a commercial anchor — any single industrial filing would immediately reshape the assignee snapshot.
Highly concentratedNo co-applicant activity detected
Evidence pending on formal co-filing collaborations; the collaboration dataset returned no entries. Each filer in the corpus appears to be operating independently. For an entrant, this suggests no established consortium or pre-competitive alliance exists that would need to be navigated, but it also means there is no collaborative infrastructure to join.
No co-filing detectedIndia is visible in filings; US presence limited to the leader
India accounts for 4 of the patent records, driven by the cluster of Indian engineering institutions. The United States accounts for 2 records, both attributable to Florida International University. Key EV-bus markets such as China, Europe, and South Korea are entirely absent from the jurisdictional footprint, representing a significant geographic gap relative to where electric bus deployment is most active.

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.
Florida International University
Florida International University holds 2 patent families — the largest share in the corpus — with technology focus spanning H02J50 (wireless power transfer), H02J7 (battery charging), and H02M3 (DC-DC conversion), as reflected in the work attributed to co-inventors Mohamed Ahmed AS and Mohammed Osama A. The US filing jurisdiction distinguishes this applicant from the rest of the corpus. Momentum data places this applicant in the prior filing window, making its trajectory relative to the recent entrants worth monitoring.
families: 2Ecole Cent School of Engineering at Mahindra University
Ecole Cent School of Engineering at Mahindra University holds 1 patent family and is flagged as a new entrant in the recent filing window. Its technology focus covers B60L53 (EV charging systems), H02J50 (wireless power), and H02J7 (charging control) — a profile oriented toward the vehicle-side integration of wireless charging rather than converter electronics. Dr. M.G.R. Educational & Research Institute shares the same new-entrant status and a similar IPC profile, making the two institutions the most recent additions to the field.
families: 1Frequently asked questions
The current corpus contains 6 patent families in scope. This is a very small corpus, reflecting the early-stage and predominantly academic nature of patenting activity in this specific niche.
Florida International University is the leading filer with 2 patent families — the largest share in the corpus. All other applicants hold 1 family each.
India accounts for 4 patent records in the corpus, driven by a cluster of Indian engineering colleges. The United States accounts for 2 records, both from Florida International University. No other jurisdictions appear in the evidence.
B60L (electric vehicle propulsion) and H02J (power supply and grid systems) each cover all 6 patent records. H02M (power conversion) covers 4 records. No other IPC classes appear, indicating a tightly bounded technology footprint.
No. All five filers in the corpus are universities or engineering institutes. No automotive OEM, charging-infrastructure provider, or power-electronics company appears in the evidence.
Filing activity was recorded in 2017 (2 families), then absent through 2023, before resuming with 2 families in 2024 and 2 in 2025. Given the small corpus size, each individual filing represents a significant share of total activity. The 2024–2025 figures are subject to publication lag and should be treated as provisional.
