Magnetic Resonance Power Transfer Patents: Top Companies & Trends 2026
Magnetic Resonance and Mid-Range Power Transfer Patents
70.3% concentration. The top 5 of 39 ranked assignees together hold 26 of the 37 records in scope — a field with a small controlling group and a long single-filing tail. Filings rose from 0 in 2017 to a peak of 11 in 2022, then declined toward the -100% mark recorded between 2021 and 2024. Treat 2025 and 2026 as incomplete rather than as evidence the field has gone quiet.

Common questions on this landscape
Who holds the most patents in magnetic resonance and mid-range wireless power transfer?
In this 37-record dataset, one assignee leads with 11 records, and the top 5 of 39 ranked assignees together hold 26 records, or 70.3% of everything in scope. That means a small group of applicants controls most of the filed claim language, particularly around impedance matching and integrated transfer systems. Anyone filing new claims in this space should expect to draft around, or license from, that leading cluster rather than assuming open ground.
Is patent filing in wireless power transfer still growing?
Filing peaked at 11 records in 2022 and then fell sharply, with a recorded -100% change between 2021 and 2024. However, publication typically lags filing by around 18 months, so the 2025 and 2026 figures in any dataset are still incomplete at the time of search. The honest reading is that the field cooled after 2022 by the numbers we can currently see, not that it has stopped — later years will fill in as more records publish.
What technology areas do these patents actually cover?
Almost all records, 91.9% of the 37 in scope, touch H02J power-supply-and-grid-system claims, making this primarily a systems-level field rather than a materials or coil-design one. H01F (magnetics and transformers) and H02G (cable installation) each cover 29.7% of records, and B60L (electric vehicle propulsion) reaches 16.2%, pointing to a secondary automotive-charging use case. Because a single record can carry several IPC classes, these percentages overlap rather than sum to 100%.
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 Magnetic Resonance and Mid-Range Power Transfer 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.
