Low-Power MEMS Accelerometer Patent Snapshot 2026
The low-power MEMS accelerometer patent space is tightly concentrated, with Analog Devices and Texas Instruments collectively anchoring the field and the top five filers commanding the large majority of ranked activity. The field has expanded substantially on a multi-year basis, though annual volume peaked in 2022 and the most recent years remain understated by publication lag.
Analog Devices leads a highly concentrated field
Analog Devices Inc holds the top position with 8 patent records, followed closely by Texas Instruments Inc with 7, making the two firms the clear first tier in low-power MEMS accelerometer patenting.
The top five filers account for 88% of the combined total among the ranked applicants visible in this query, indicating a markedly oligopolistic structure with a steep drop-off after the first two incumbents. Intel Corp, the Regents of the University of Michigan, and inventor Lee James M each hold 2 patent records, forming a thin second tier.

The incumbents’ entrenched positions suggest that new entrants face a well-covered core evidence snapshot in mainstream sensing (G01P) and must differentiate through adjacent technology routes or application domains to find defensible space.
The most recent 18–24 months of filings are likely under-counted due to patent publication lag and should not be interpreted as a slowdown in activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Multi-year growth with a 2022 peak and a broadening technology mix
The filing trend and technology composition charts together reveal a field that surged to a 2022 peak and carries a diverse but G01P-visible IPC footprint, with meaningful secondary presence in digital processing and navigation.
Annual filing trend
Filings were negligible through 2020, accelerated sharply to a peak of 4 in 2022, then eased to 3 in 2023; 2024–2026 values are suppressed by publication lag and should not be read as contraction. The 133% recent-window growth confirms the field is still expanding on a multi-year basis.

G01P (velocity and acceleration) is visible in the IPC mix, reflecting core sensing claims, while G06F (digital data processing) and G01C (navigation and gyroscopes) represent meaningful secondary branches — the latter driven largely by Texas Instruments’ navigation-oriented portfolio.

System and method for a three-axis MEMS accelerome…
A system and method for inputting motion measurement data into a computationally based device are provided. In a first version three-axis accelerometer determines components of an inertial force vector with respect to an orthogonal coordinate system. The accelerometer includes a sensor die made of a semiconductor substrate having a frame element, a proof… (excerpt from the patent abstract)

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope.

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.
Analog Devices Inc
Analog Devices holds 8 patent records — the highest in the ranked set — with technology emphasis concentrated in G01P 15 (acceleration sensing, 6 records) and secondary coverage in G11B 19 (information storage) and G01P 1. Analog Devices also anchors the collaboration network, co-filing with inventor Lee James M and Memishian John. No recent-window momentum data is available for Analog Devices in the applicant momentum evidence, suggesting an established rather than accelerating filing posture.
patent records: 8Texas Instruments Inc
Texas Instruments holds 7 patent records and distinguishes itself with a dual focus: G01C 21 and G01C 22 (navigation and gyroscopes, 6 records each) alongside G01P 15 (acceleration sensing, 6 records), indicating a systems-level approach that integrates MEMS sensing into navigation pipelines. Texas Instruments is flagged as a new entrant in the recent filing window with 4 recent filings, signaling an accelerating commitment to this space.
patent records: 7Frequently asked questions
Analog Devices Inc leads with 8 patent records, followed by Texas Instruments Inc with 7. These two firms form a clear first tier, well ahead of the next-ranked filers.
The recent three-year filing window is 133% above the prior three-year window, confirming multi-year growth. Annual filings peaked at 4 in 2022 and eased to 3 in 2023; the most recent years are further understated by publication lag.
The United States leads with 20 patent records. WIPO/PCT filings stand at 3, China at 2, and India at 1, indicating that international protection outside the US remains limited.
G01P (velocity and acceleration) is the visible class, followed by G06F (digital data processing) and G01C (navigation and gyroscopes). G01C coverage is largely attributable to Texas Instruments’ navigation-focused portfolio.
Analog Devices is the most active co-filer, with 2 joint filings alongside Lee James M and 1 alongside Memishian John. The overall collaboration network is small, and most filers appear to pursue innovation independently.
B81B (microstructural MEMS fabrication) and H02N (electrostatic and energy-harvesting machines) each carry very low patent record counts in this corpus, making them the sparsest adjacent branches relative to the visible G01P class.

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.
