Overview
What this landscape covers
Dynamic wireless charging — transferring power to a vehicle or device while it moves, rather than while parked over a stationary pad — sits at the intersection of power electronics, EV propulsion and RF/communications control. The dataset behind this page pulls 1,155 published records filed between 2015 and 2026 that claim dynamic wireless power transfer or dynamic wireless charging, drawn from title/abstract and claims text matching that intent directly rather than static inductive charging alone.
Because publication lags filing by roughly 18 months, the most recent one to two years in any trend understate real filing activity. The picture below treats 2024 as the last complete year and reads 2025-2026 as still filling in.

The Numbers
Filing trend and technology composition
Two views of the same 1,155 records: how filing volume has moved year over year, and which IPC subclasses carry the claim density once a record can be tagged with more than one class.
Filing trend: steady build, not a plateau
Filings moved from 82 in 2017 to a peak of 209 in 2025, with the reliable growth window — 2021's 113 to 2024's 157 — showing a 39% rise over three years. Treat 2025 and 2026 figures as provisional; they will revise upward as later publications land.
Publication lags filing by roughly 18 months, so 2025 onwards are still filling in. Growth rates on this page therefore end at 2024; running them to the last bar would understate the field.
Where the claims sit: power supply first, EV propulsion close behind
H02J (power supply and grid systems) touches 89.4% of the 1,155 records, and B60L (electric vehicle propulsion) touches 43.0% — the two together frame most of the field as an electrical-engineering and automotive problem. H04B (general transmission), H01F (inductors and transformers), G06F, H04W, A61B and H02M each cover a smaller but still meaningful slice, since a single record can carry several IPC tags.
Shares are the percentage of the 1,155 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

What the numbers mean for a filing decision
Three read-throughs from the ranking, the trend and the technology composition — not a repeat of the tables, but what they imply for where to file next.
Concentration
21.5%
of 1,155 records held by the top five assignees
Leadership is real but not exclusionary
The leader holds 80 records and fifth place holds 33 — a meaningful gap, but the top five together still account for only 21.5% of all records in scope. That leaves a long tail of single- and few-filing entrants with room to build a position, particularly outside the leader's core claim territory.
Ranking covers 100 companies, not a top-50 or top-100 cut.
Growth
+39%
filing growth, 2021 to 2024
Activity is still climbing, not cooling
Filings rose from 113 in 2021 to 157 in 2024, the last year this dataset treats as complete. That is sustained growth over a three-year span, not a single spike, and it argues against reading any dip in 2025-2026 figures as a real slowdown — those years are still filling in as publications catch up to filing dates.
2025's 209 filings are provisional and will revise upward.
Technology mix
89.4% / 43.0%
records touching H02J / B60L
Power-supply framing dominates over communications framing
H04B, the general transmission and communications class, reaches only 14.1% of records, while H01F (inductors/transformers) sits at 11.4% and H04W (wireless networks) at 7.8%. The bulk of claim density is still in power delivery and vehicle integration, which leaves the communications-and-coordination layer for dynamic charging comparatively lightly claimed.
Shares sum above 100% because records carry multiple IPC tags.
Filing geography
462 / 306 / 258
US / India / China receiving-office filings
Three offices carry most of the volume
The United States, India and China are the largest receiving offices in this dataset, ahead of the EPO's 180 and WIPO's 136 PCT filings. A company benchmarking freedom-to-operate should treat these three jurisdictions as the ones where prior art density is highest and clearance work is most urgent.
AT (Austria) trails at 36 filings among the offices tracked.

Only 6 co-assignee pairs appear in this dataset, and the strongest — a university paired with a provincial power-grid research institute, at 20 shared records — suggests most dynamic-charging IP here is filed by single entities rather than joint ventures or research consortia.

What's Next
Where to take this from here
The ranking and trend answer who and how fast. The next questions are what to file around and who actually blocks a given claim — both need a closer read of the underlying documents.
Map white space inside the under-claimed branches
H04B, H04W and G06F together sit well below H02J and B60L in claim density. That gap is where a coordination, communications-protocol or software-control claim is less likely to collide with existing art.

FAQ
Common questions about dynamic wireless charging patents
The ranked leader in this dataset holds 80 records, with a clear step down to 33 at fifth place and 20 at tenth. Even so, the top five combined account for only 21.5% of the 1,155 records in scope, so no single company controls the field outright. The ranking covers 100 companies total, and a long tail of entrants below that line hold one or a handful of filings each, which is where most competitive movement is likely to be happening now.
It is growing. Filings rose from 113 in 2021 to 157 in 2024 — a 39% increase over that three-year span, and 2024 is the most recent year this dataset treats as complete. Figures for 2025 and 2026 look lower, but that reflects publication lag of roughly 18 months rather than an actual drop in filing activity; those years will revise upward as more records publish.
H02J, power supply and grid systems, is the dominant class, touching 89.4% of the 1,155 records in scope. B60L, electric vehicle propulsion, follows at 43.0%, reflecting how much of this technology is framed around vehicle integration. Smaller but still significant classes include H04B (general transmission, 14.1%), H01F (inductors and transformers, 11.4%), G06F (9.2%), H04W (7.8%), A61B (6.1%) and H02M (6.1%) — a single record commonly carries several of these tags at once.
The United States leads with 462 filings in this dataset, ahead of India at 306 and China at 258. Europe via the EPO follows at 180, with WIPO PCT filings at 136 and Austria at 36. Anyone assessing freedom-to-operate risk should prioritise clearance work in the US, India and China first, since those three offices carry the bulk of the documented volume.
US20110074349A1, covering systems and methods for providing wireless power to a portable unit, is cited 469 times in this corpus — the highest of any record tracked. It is followed closely by two records on wireless power transmission with selective range and one on receiver sleep-mode behaviour, all cited in the 300s. High citation counts reflect influence within this searched corpus and tend to favour older filings, so they should be read as a signal of foundational importance rather than current market relevance.
