MEMS Accelerometer Quality Control Patent Snapshot
Texas Instruments dominates this compact, highly concentrated field, holding a commanding share among the handful of active filers. Filing activity has plateaued near its 2019–2022 peak, signalling a mature but stable technology domain with limited new entrants.
Texas Instruments leads a tightly held, mature niche
Texas Instruments Inc ranks first among all filers, accounting for 8 patent records — the largest single-applicant position in this corpus. Delco Electronics Corporation, STMicroelectronics Int NV, and InvenSense Inc each hold 2 patent records, while Delphi Technologies Inc holds 1.
The top five filers together account for 100% of the ranked applicants visible in this query’ combined total, indicating extreme concentration with no meaningful second tier. There is no observable challenger closing the gap with the leader.

Texas Instruments’ visible position, supported by a focus spanning navigation, acceleration measurement, and digital data processing, reflects long-standing, consolidated IP in sensor calibration and self-test methodologies. New entrants face a well-staked evidence snapshot with little room between the established players.
Patent publication typically lags filing by 18–24 months; the zero counts recorded for 2024–2026 reflect this lag rather than confirmed inactivity, and should not be read as a cessation of filing. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filings have plateaued; sensor measurement classes dominate the technology mix
The annual filing trend and technology composition together reveal a field that grew to a modest plateau around 2019–2022 and is now showing the characteristics of a mature niche. The IPC class distribution highlights which technical problems have attracted the most patent activity.
Annual filing trend
Filings rose from zero in 2017–2018 to 2 patent records per active year across 2019, 2020, 2022, and 2023, with no recorded filings in 2021 or in 2024–2026. The 2024–2026 absence reflects publication lag and should not be interpreted as a confirmed drop. The overall pattern is consistent with a field that has plateaued near its peak rather than one in active growth.

G01P (Velocity & acceleration) is the visible IPC branch with 13 patent records, followed by G06F (Electric digital data processing) at 8 and G01C (Distance, navigation & gyroscopes) at 7. Foundational MEMS-specific classes — B81B (Microstructural devices) and B81C (MEMS manufacturing) — each carry only 3 and 2 patent records respectively, pointing to thin coverage at the device and process level relative to the measurement and data-processing layer.

Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Texas Instruments Inc
Texas Instruments holds 8 patent records — the largest position in this corpus. Its technology focus spans G01C 21 and G01C 22 (Distance, navigation & gyroscopes) and G01P 15 (Velocity & acceleration), indicating a strong orientation toward navigation integration and sensor measurement quality rather than device fabrication. No momentum trend data is available in the evidence.
patent records: 8Delco Electronics Corporation
Delco Electronics Corporation holds 2 patent records, with its technology emphasis concentrated in B81B 3 (Microstructural devices — MEMS), G01P 1, and G01P 15 (Velocity & acceleration). This device-level focus is technically complementary to — but structurally distinct from — Texas Instruments’ navigation and calibration orientation. No momentum trend data is available in the evidence.
patent records: 2Frequently asked questions
The corpus contains 8 patent families in scope. This is a compact, specialist niche rather than a high-volume technology area.
Texas Instruments Inc is the leading filer with 8 patent records — more than any other applicant in the corpus. Delco Electronics Corporation, STMicroelectronics Int NV, and InvenSense Inc each follow with 2 patent records.
No. The lifecycle evidence indicates annual filings have plateaued near their peak. The most active years were 2019, 2020, 2022, and 2023. Zero counts for 2024–2026 reflect publication lag rather than confirmed inactivity, but the field’s overall trajectory is consistent with maturity rather than growth.
G01P (Velocity & acceleration) is the most represented branch with 13 patent records, followed by G06F (Electric digital data processing) at 8 and G01C (Distance, navigation & gyroscopes) at 7. MEMS-specific fabrication classes such as B81B and B81C are comparatively thin.
The United States is the visible jurisdiction with 13 patent records. Europe (EPO) accounts for 2 patent records. No other jurisdictions appear in the evidence, indicating a US-centric filing strategy among active applicants.
No co-applicant filings have been identified in this corpus. The landscape appears to be driven by individual corporate IP strategies, with no cross-institutional or supply-chain collaboration activity visible in the evidence.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
