Bone Conduction Patents: Who Leads, Where the Gaps Are 2026
Bone Conduction and Alternative Transducer Patents
54.0% concentration. The top 5 of 31 ranked assignees account for 27 of the 50 records in scope — filing here is concentrated rather than fragmented. Filings rose from zero in 2017 to a peak of 4 in 2020, then settled into a flat pattern: 2 records in 2021 and 2 in 2024, a 0% change over that three-year span. 2025 and 2026 figures will revise upward as publication catches up with filing, so treat the tail of the chart as incomplete rather than as a decline.

Common questions about this landscape
Who holds the most bone conduction transducer patents?
One assignee leads the ranked list with 10 of the 50 records in scope, noticeably ahead of the fifth-ranked company at 3 records. The top 5 assignees together account for 54.0% of all records, and the top 10 account for 78.0%, which means the field has a clear leadership tier followed by a long tail of companies with only one or two filings each. Anyone doing freedom-to-operate work should check the leader’s portfolio specifically rather than assuming the field is evenly distributed.
Is bone conduction patent activity growing or slowing down?
Filings peaked at 4 records in 2020 and have since held flat, with 2021 and 2024 both showing 2 records — a 0% change over that span. Because patent publication typically lags filing by around 18 months, the 2025 and 2026 figures in this dataset are still incomplete and should not be read as a decline. The honest read is a plateau since 2020 rather than clear growth or a clear drop.
What patent classes cover bone conduction technology?
H04R, the loudspeakers and audio transducers class, covers 76.0% of the 50 records in scope and is by far the dominant classification. Smaller clusters appear in A61F (implants and prostheses), G02C (spectacles and lenses), G06F (data processing) and H04B (transmission), each at 10.0% of records, with A61H, G09B and A61B trailing further behind. Because a single record can carry multiple IPC codes, these shares add up to more than 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 Bone Conduction and Alternative Transducers 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.
