MEMS Accelerometer Materials Patent Snapshot 2026
This is a compact, highly concentrated field with the top five filers accounting for half of activity among the hundred largest filers, and a single geophysics-focused alliance dominating the leading position. The field is still expanding on a multi-year basis, with recent-window growth of 57%, though annual volume has eased from its 2023 peak and the most recent years remain understated by publication lag.
PGS Geophysical and A*STAR co-lead a concentrated niche
PGS Geophysical AS and Agency for Science, Technology and Research (A*STAR, Singapore) jointly occupy the top rank in the applicant league table, each holding 19 patent records — a commanding position relative to the third-ranked filer, MEI Micro Inc, at 6 patent records.
The top five filers together represent 50% of the combined total among the ranked applicants visible in this query, confirming a tight, two-tier structure: a visible geophysics-driven alliance at the top, a small cluster of specialist and semiconductor players in the middle, and a long tail of single-record contributors.

The leaders’ joint profile — spanning velocity and acceleration measurement, geophysics surveying, and MEMS microstructure — signals that the most protected intellectual property in this niche has been shaped primarily by seismic sensing applications rather than consumer or automotive end-markets.
The most recent filing years should be treated as understated due to standard patent publication lag of 18–24 months; apparent gaps in 2025–2026 data do not reflect true activity levels. 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 2023 activity peak and a dominant sensing core
The filing trend and technology-class breakdown together show a field that surged in 2021–2023 and remains well above its pre-2021 baseline, while the technology mix is overwhelmingly anchored in core acceleration measurement and MEMS device classes with a scatter of adjacent application branches.
Annual filing trend
Activity was negligible from 2017 to 2020 (peaking at 2 records in 2017), then jumped to 6 in 2021, reached 7 in 2023, and recorded 4 in 2024. The 57% recent-window growth confirms a genuine multi-year expansion; the zero values in 2025–2026 reflect publication lag, not a real halt, and the 2023 peak should be interpreted as a current high-water mark rather than a permanent ceiling.

G01P (velocity and acceleration measurement) is the visible branch with 89 patent records, followed by B81B (MEMS microstructural devices) at 32 and B81C (MEMS manufacturing) at 10. All other branches — including geophysics (G01V), force and pressure (G01L), navigation (G01C), and sports equipment (A63B) — each hold single-digit counts, illustrating a field anchored in device physics but reaching into diverse end-use sectors.

What the IP structure means for R&D investment decisions
The combination of strong recent growth, high concentration, a visible cross-institutional collaboration, and sparse coverage in several adjacent branches creates a specific set of conditions for entrants and incumbents alike.
Growth stage, easing from a 2023 peak
The field carries a Growth lifecycle designation: three-year recent filings sit well above the prior three-year window, with 57% growth. Annual volume has eased from the 2023 high, consistent with a field that is past its initial acceleration phase but not yet mature. New entrants MEI Micro Inc and Taiwan Semiconductor Manufacturing Co Ltd (TSMC) appearing with recent filings reinforce that the technology frontier remains open.
Lifecycle: GrowthTwo-entity alliance holds the apex; tier gap is large
PGS Geophysical AS and A*STAR together account for the top rank jointly at 19 patent records each, while the next filer trails at 6. The top five filers hold 50% of activity among the ranked applicants visible in this query. This degree of concentration in a corpus of 20 patent families means that a small number of agreements, licenses, or design-arounds can substantially alter the competitive picture.
High concentrationA*STAR–PGS Geophysical is the field’s single documented alliance
Evidence shows one active co-filing relationship: A*STAR (Agency for Science, Technology and Research) and PGS Geophysical AS have jointly filed 19 co-assigned records, which effectively defines the collaborative backbone of this niche. No other co-applicant pairs appear in the evidence, suggesting that the remainder of the field operates independently. New entrants seeking partners should note that the visible alliance spans both a public research agency and a commercial geophysics firm.
Single visible allianceUnited States leads; Europe and Asia are secondary filing destinations
The United States is the lead jurisdiction with 43 patent records, followed by Europe (EPO) at 20 and China at 7. Canada and Singapore each hold 5, with WIPO PCT filings also at 5. The presence of Singapore is notable given A*STAR’s role and Vanguard International Semiconductor Singapore’s appearance in the ranking. China’s relatively low count suggests either limited domestic filing by current leaders or an under-served entry point for local applicants.

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.
PGS Geophysical AS
PGS Geophysical AS holds 19 patent records, co-equal with A*STAR at the top of the ranking. Its technical focus is concentrated in G01P 15 (velocity and acceleration measurement, 19 records) and G01V 1 (geophysics and gravity surveying, 9 records), with secondary coverage in B81B 7 (MEMS microstructural devices, 3 records). The entire portfolio is co-filed with A*STAR, indicating that this position is inseparable from the bilateral alliance. No momentum trend data is available for this applicant in the recent-window analysis, suggesting an established rather than accelerating position.
patent records: 19MEI Micro Inc
MEI Micro Inc ranks third overall with 6 patent records and is flagged as a new entrant in recent-window momentum analysis. Its focus spans G01P 15 (velocity and acceleration measurement, 6 records), with single records in B64G 1 (cosmonautics and spacecraft) and B81B 7 (MEMS microstructures), pointing to an aerospace-grade sensing application profile. The new-entrant designation from a small prior base merits monitoring to determine whether its trajectory continues into a sustained filing program.
patent records: 6Frequently asked questions
The corpus analyzed contains 20 patent families. This is a niche corpus, so concentration metrics and trend readings should be interpreted in that context.
PGS Geophysical AS and Agency for Science, Technology and Research (A*STAR, Singapore) are co-ranked first, each with 19 patent records. MEI Micro Inc ranks third with 6 patent records, followed by the Board of Trustees of the Leland Stanford Junior University at 5 and several filers tied at 4.
The field is classified as Growth: recent three-year filings are 57% above the prior three-year window. Annual volume peaked in 2023 at 7 records and has eased since, but the multi-year trajectory remains expansionary. The most recent years (2025–2026) show zero records due to publication lag rather than a real halt.
The United States leads with 43 patent records, followed by Europe (EPO) at 20 and China at 7. Canada and Singapore each hold 5 records, and WIPO PCT filings also total 5. China’s relatively low count may indicate limited filing by current leaders in that market.
G01P (velocity and acceleration measurement) is visible in with 89 patent records. B81B (MEMS microstructural devices) is a strong secondary class at 32 records, followed by B81C (MEMS manufacturing) at 10. All other branches, including G01V (geophysics), G01L (force and pressure), and G01C (navigation), hold single-digit counts.
MEI Micro Inc and Taiwan Semiconductor Manufacturing Co Ltd (TSMC) are both flagged as new entrants in the recent filing window. MEI Micro’s 6 recent patent records focus on acceleration measurement and aerospace applications, while TSMC’s recent records concentrate on MEMS fabrication and manufacturing process classes. Both entered from a near-zero prior base.
