MEMS Speakers Patents: Top Companies & Filing Trends 2026
MEMS speaker and micro actuation patents: who is filing, and where the claim space still sits open
One assignee alone accounts for 38 of 115 records, while the ranked field runs 29 companies deep before the trail thins to single filers. Filings rose from a single record in 2017 to a peak of 25 in 2022, then continued at a lower but still active pace. The +29% climb from 7 records in 2021 to 9 in 2024 is the cleanest complete-year comparison available; treat 2025 and 2026 figures as undercounts until later publication catches up.

Common questions on MEMS speaker patents
Who holds the most MEMS speaker patents?
One assignee leads the field with 38 of the 115 records in scope, well ahead of the rest of the ranked list. The ranking covers 29 companies in total, and concentration drops off quickly: fifth place holds only 4 records and tenth place holds 3. Anyone doing competitive tracking or clearance work should treat the leader’s portfolio as the first stop, since it alone accounts for a third of all filings in this dataset.
Is MEMS speaker patent filing still growing?
Yes, on the most reliable comparison available: filings rose from 7 in 2021 to 9 in 2024, a 29% increase, after an earlier peak of 25 records in 2022. Counts for 2025 and 2026 look lower, but that reflects the roughly 18-month lag between filing and publication rather than a real drop in activity. A fair read of momentum should wait for those later years to finish publishing before drawing conclusions.
What technology areas does MEMS speaker patenting actually cover?
The large majority of records, 93.9% of 115, sit in IPC class H04R, covering loudspeakers and audio transducers generally. A smaller share, 21.7%, also carries B81B for microstructural MEMS devices, and just 2.6% touches B81C, MEMS manufacturing specifically. This means most patenting activity protects the acoustic transducer function itself, with comparatively less claimed around the underlying MEMS fabrication process.
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 MEMS Speakers and Micro Actuation 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.
