Capacitive MEMS Accelerometer Patents: Top Companies & Trends 2026
Capacitive MEMS accelerometer patents: who holds the ground and where it is still open
30.9% of all 2,693 records sit with just five assignees, so the field reads as concentrated at the top rather than fragmented. Annual filings peaked in 2019 at 141 and have since declined; the -43% move from 106 filings in 2021 to 60 in 2024 is the most recent span the dataset can treat as complete. 2025 and 2026 figures will fill in as publication catches up, so they should not be read as a continued drop yet.

Common questions on this landscape
Who holds the most capacitive MEMS accelerometer patents?
The ranked assignee list is led by a single company holding 220 of the 2,693 records in scope, well ahead of the fifth-ranked assignee at 76 and the tenth at 50. The top five combined hold 30.9% of all records, and the top ten hold 42.4%, which means the field is concentrated at the top but still leaves a long tail of smaller filers. Consumer inertial-sensor makers, automotive suppliers, foundries and at least one geophysical survey specialist all appear among the ranked leaders, so the leadership is not confined to one industry segment.
Is capacitive MEMS accelerometer patenting still growing?
No — filings peaked in 2019 at 141 and fell to 60 by 2024, a 43% drop from the 106 filed in 2021. That 2021-to-2024 span is the most recent one the dataset can treat as complete, because publication typically lags filing by about 18 months, so 2025 and 2026 counts will keep rising as more records publish. The honest read is a cooling filing rate since the 2019 peak rather than a market in decline, since underlying demand for inertial sensing in automotive and consumer devices has not disappeared.
Which patent classes matter most for capacitive MEMS accelerometers?
G01P (velocity and acceleration measurement) and B81B (MEMS microstructural devices) are the two dominant classes, covering 39.5% and 32.3% of the 2,693 records respectively. B81C (MEMS manufacturing methods) follows at 19.9%, and H01L (semiconductor devices) at 15.3% shows how much of the field also touches integration with standard IC processes. Because a single record can carry several classes, these figures add up to more than 100% of records and should not be treated as mutually exclusive shares.
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 & NEMS — Capacitive MEMS Accelerometers Patent Landscape 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.
