Wireless Power Transfer Patents: Top Companies & Filing Trends 2026
Wireless power transfer patents: who holds the ground and where claim space is still open
23.6% sits with five companies. The top five assignees account for 3,032 of 12,874 records in scope, with a long tail of single- and few-filing entrants behind them. Filings ran from 1,142 in 2017 to a peak of 1,220 in 2021, then eased to 730 by 2024 — a 40% decline over that three-year window. 2025 and 2026 figures (96 in the most recent year) are still filling in under the usual 18-month publication lag and should not be read as a continuing drop.

Common questions about the wireless power transfer patent landscape
Who are the leading patent holders in wireless power transfer?
The assignee ranking is led by a single company with 1,041 records, well ahead of the fifth-place holder at 371. The top five assignees combined account for 23.6% of the 12,874 records in scope, and the top ten reach 32.5%. Beyond the top ten, coverage thins quickly into a long tail of companies with a small number of filings each, so most of the field’s activity is not held by a handful of names but spread across many smaller filers.
Is wireless power transfer patent filing activity growing or slowing?
Filing volume peaked in 2021 at 1,220 records and had fallen to 730 by 2024, a 40% decline over that three-year span using the last fully mature filing years available. Because publication typically lags filing by around 18 months, the lower counts shown for 2025 and 2026 are incomplete rather than evidence of a further collapse. Anyone assessing momentum should anchor on the 2021–2024 comparison rather than the most recent one or two years.
What technology areas dominate wireless power transfer patents?
Power supply and grid systems (IPC class H02J) appear in 58.3% of the 12,874 records, making it by far the largest single class in the dataset. Transmission-general claims (H04B) follow at 21.6%, with magnetics and inductor claims (H01F) at 11.1%. Electric vehicle propulsion (B60L, 8.1%) and medical diagnosis and surgery (A61B, 6.2%) mark the field’s two clearest downstream applications, layered on top of the core conversion and transmission art.
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.
