Induction Heating Patents: Who Leads, Where the Gaps Are 2026
Induction Heating Patents: Mapping Who Leads and Where Claim Space Is Still Open
49.8% concentration. The top five assignees combined hold 2,835 of the 5,689 records in scope — just under half the entire field sits with five filers. Filings rose from 179 in 2017 to a peak of 683 in 2020, then declined; the 2021-to-2024 span alone fell 44%, from 512 to 287. 2025 and 2026 figures are understated by publication lag and should not be read as a continuing collapse.

Common questions about induction heating patents
Who holds the most induction heating patents?
The dataset’s assignee ranking is concentrated at the top: the five largest filers together account for 2,835 of 5,689 records in scope, or 49.8% of the field. The leading assignee alone holds 1,526 records. Beyond the top ten filers, who together hold 57.4% of records, the ranking spreads into a long tail of smaller filers, so most freedom-to-operate risk sits with a small number of large portfolios rather than being evenly distributed.
Is induction heating patent filing growing or slowing down?
Filing activity peaked in 2020 at 683 records and has fallen since, dropping 44% from 512 filings in 2021 to 287 in 2024. Because patent publication typically lags actual filing by around 18 months, the lower counts shown for 2025 and 2026 are still filling in and should not be read as proof the field is cooling further. Treat 2024 as the most recent year with a reasonably complete count.
What is the difference between induction heating patents for consumer devices and industrial process heating?
In this dataset, IPC class A24F (smokers’ requisites) covers 42.6% of records and A24D (cigars, cigarettes and filters) another 16.2%, together outweighing the general electric-heating circuit class H05B at 31.0%. That means a large share of induction-heating patent activity documented here relates to heat-not-burn consumer devices rather than bulk industrial billet or furnace heating, so searches aimed at industrial process equipment need to filter past the consumer-device cluster deliberately.
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 Induction Heating for Process Industry 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.
