Dynamic Wireless Charging Patents: Who Leads, Where the Gaps Are 2026
Dynamic and In-Motion Wireless Charging Patents: A Field Still Taking Shape
Concentrated at the top. The top 5 assignees hold 62.1% of all 29 records in scope, and the top 10 hold 86.2% — this is a small, tightly held field, not a crowded one. Filings were at zero in 2017 and reached a partial-year count of 3 by 2026. The tracked peak so far is 2025 at 8 records, but publication lags filing by roughly 18 months, so both 2025 and 2026 will continue to fill in as more records publish. The one complete year-over-year comparison the data supports is 2021 to 2024, where filings fell from 3 to 1 — a 67% decline. Treat any read of 2025-2026 as provisional rather than as evidence of renewed acceleration.

Common questions about this landscape
How many patents exist for dynamic wireless charging technology?
This dataset identifies 29 published records in scope, filed between 2015 and 2026, covering technical areas such as segment switching, power fluctuation, road-embedded coils, vehicle detection, installation cost and electromagnetic exposure. That is a small corpus compared with adjacent electric-vehicle technologies, reflecting that dynamic charging is a narrower and newer sub-field than static wireless charging or EV powertrains generally. Because publication lags filing by roughly 18 months, the most recent years in this count will keep rising as more filings publish.
Who are the leading patent holders in dynamic wireless charging?
The ranking covers 30 companies in total, counted by patent family, with the leading assignee holding 6 of the 29 records in scope. Concentration is notable for a field this size: the top 5 assignees together hold 62.1% of all records, and the top 10 hold 86.2%. Beyond the leading group the ranking thins quickly, with fifth place holding 2 records and tenth place just 1, indicating a long tail of single- or double-filing entrants rather than a broad competitive base.
Is patent filing activity in dynamic wireless charging increasing or slowing down?
The only complete year-over-year comparison this dataset supports is 2021 to 2024, over which filings fell from 3 to 1 — a 67% decline. Figures for 2025 and 2026 show higher raw counts, including a tracked peak of 8 in 2025, but those years are still incomplete because publication typically lags filing by about 18 months. Read the 2025-2026 uptick cautiously rather than as confirmed renewed growth until later data cuts fill those years in.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Dynamic and In-Motion Wireless Charging covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
