Wireless EV Charging for Passenger Vehicles Patent Landscape
The corpus in scope contains only 2 patent families, with activity concentrated across two applicants — Audi AG and Francis Xavier Engineering College — signalling that this precise sub-field remains at a very early, pre-competitive stage. The dominant technical branch is B60L (electric vehicle propulsion), with filings appearing in Germany and India.
Two applicants share the entire corpus — concentration is absolute
The ranked applicant list is led by Audi AG and Francis Xavier Engineering College, each holding 1 patent family. Together they account for 100% of the top hundred filers’ combined total, meaning no other organization has yet established a meaningful position in this precisely defined sub-field.
With only two applicants, there is no meaningful tier gap to describe — the field has not yet reached the stage where a visible incumbent and a trailing challenger bracket exists. Both filers are first movers at this level of specificity.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Audi AG | 1 | |
| 2 | Francis Xavier Engineering College | 1 |
Audi AG’s presence indicates that at least one major OEM has begun staking IP territory in wireless passenger-vehicle charging, while the appearance of Francis Xavier Engineering College suggests academic-side exploration. Neither position is large enough to signal locked-in exclusivity.
The most recent filing period is subject to publication lag of approximately 18–24 months, so the apparent absence of 2024–2026 activity should not be read as stagnation; additional families may not yet be publicly visible.
Sparse, episodic filings with a broad but shallow technology mix
The annual trend and technology composition charts together reveal a field that has produced isolated filings rather than a sustained wave of innovation, with the technical scope spanning propulsion, power conversion, and data processing branches.
Annual filing trend
Filings are effectively zero across most of the decade, with a single family recorded in 2023 and one in 2025. The 2024 and 2026 zeros should be treated cautiously given publication lag; it is too early to interpret the recent period as a trend. Overall, the annual cadence shows no established growth trajectory.

B60L (electric vehicle propulsion) is the anchor class, appearing in both families, which confirms that charging-system integration is the primary frame. Secondary branches — B60R (vehicle parts and accessories), G06F (digital data processing), G08C (transmission of measured values), H02J (power supply and grid systems), and H02M (power conversion) — each appear once, indicating broad but thin coverage across the wireless charging stack.

What the structure means for R&D investment decisions
With only 2 patent families and 2 applicants, competitive intelligence drawn from this corpus is necessarily limited. The observations below reflect the current evidence and should be updated as publication lag resolves.
Pre-competitive, embryonic stage
The lifecycle stage cannot be formally classified from available evidence — the corpus is too small to derive a statistically meaningful stage label. Practically, two isolated filings over a decade-long window, with no year producing more than one family, places this sub-field in an embryonic, pre-competitive phase. Entrants face minimal incumbent IP friction at this level of specificity.
Early stage100% of ranked activity held by two filers
The top five filers account for 100% of the ranked applicants visible in this query’ combined total — but in practice there are only two filers. This level of concentration is an artifact of corpus size rather than strategic lock-in. Any new entrant filing even a handful of families would materially shift the competitive balance. The concentration metric will be more meaningful once the corpus grows.
Duopoly (nascent)No co-applicant activity detected
Evidence pending — the collaboration data shows no co-filed patents within the in-scope corpus. Neither Audi AG nor Francis Xavier Engineering College has pursued joint filings in this sub-field based on available records. This absence may reflect the early stage of the technology rather than a deliberate go-it-alone strategy, and should be revisited as the corpus expands.
No co-filingGermany and India are the only active jurisdictions
Patent activity has been filed in Germany (one record) and India (one record), corresponding to the home jurisdictions of the two applicants. There is currently no coverage in major EV markets such as the United States, China, Japan, or South Korea. This leaves those jurisdictions entirely open at the patent level for this specific sub-field, subject to confirmation as publication lag clears.

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.
Audi AG
Audi AG holds 1 patent family, filed in Germany (DE102023109384B4). Its technical emphasis spans B60L 53 (electric vehicle propulsion), B60R 16 (vehicle parts and accessories), and G06F 8 (digital data processing), suggesting an integrated systems approach to wireless charging. Applicant momentum is recorded as a new entrant, consistent with a single recent filing rather than a sustained programme.
Patent families: 1Francis Xavier Engineering College
Francis Xavier Engineering College holds 1 patent family, filed in India (IN202541071185A). Its technical focus covers B60L 53 and B60L 55 (electric vehicle propulsion sub-classes) and H02J 50 (wireless power transfer within power supply systems), indicating a more power-transfer-centric approach compared to Audi AG’s system-integration framing. No momentum trend data is available beyond the single filing.
Patent families: 1Frequently asked questions
The in-scope corpus contains 2 patent families. This is a very small corpus, which limits the statistical confidence of trend and concentration readings.
Audi AG and Francis Xavier Engineering College each hold 1 patent family, making them the only two filers currently identified in the corpus. Audi AG is the top-ranked applicant.
Germany and India are the only jurisdictions with recorded activity, corresponding to the home bases of the two applicants. Major EV markets including the United States, China, Japan, and South Korea show no coverage in this specific corpus.
B60L (electric vehicle propulsion) is the primary IPC class, appearing in both families. Secondary branches — B60R, G06F, G08C, H02J, and H02M — each appear in a single record, indicating a broad but shallow technology spread.
Not necessarily. Patent applications typically take 18–24 months to be published after filing. The absence of records in 2024 and 2026 is likely explained by publication lag rather than a genuine drop in activity; conclusions about recent trends should be deferred until more records become visible.
Based on current evidence, H02M (power conversion) and G08C (transmission of measured values and control signals) are the most sparsely covered branches adjacent to the core B60L anchor. Both have plausible technical relevance to wireless charging systems and currently carry only one record each, suggesting minimal incumbent IP friction at this level of specificity.

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.
