MEMS-ASIC Interface Patent Landscape 2026
The MEMS-ASIC interface field is moderately concentrated, with InvenSense leading by a wide margin and the top five filers together holding 46% of the top hundred filers’ combined activity. The field has matured around inertial sensing, with annual volume plateauing near its 2023 peak while adjacent branches such as navigation and geophysics remain comparatively sparse.
InvenSense dominates a moderately concentrated field
InvenSense holds the leading position with 34 patent records, roughly half again as many as the next-ranked filer, Merlin Tech (23 patent records), and nearly double Analog Devices (20 patent records).
The top five filers collectively account for 46% of the hundred largest filers’ combined total, indicating meaningful concentration at the top without complete dominance — challengers including Honeywell International and PGS Geophysical hold credible positions in the second tier.

InvenSense’s lead is anchored in velocity and acceleration sensing (G01P) and MEMS microstructure design (B81B), suggesting that the dominant IP position is tightly coupled to inertial measurement unit architectures — entrants differentiating in adjacent domains such as navigation or geophysics face a less crowded landscape.
The most recent 18–24 months of filing data are subject to publication lag and should be read as underestimates of actual activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Annual volume has plateaued near its 2023 peak; inertial sensing dominates the technology mix
Two charts capture the temporal and technical structure of MEMS-ASIC interface patenting: an annual filing trend from 2017 onward, and the IPC class composition across the corpus.
Annual filing trend
Annual filing counts rose from 9 in 2017 to a peak of 19 in 2023, then eased to 13 in 2024. The 2025 and 2026 readings are materially affected by publication lag and should not be interpreted as a real decline. The multi-year trend is one of a field that expanded through the early 2020s and is now plateauing at a mature level of activity.

G01P (velocity and acceleration) is the dominant class by a wide margin, reflecting the field’s center of gravity in MEMS accelerometers and inertial measurement. B81B (MEMS microstructure) and G01C (navigation and gyroscopes) are the next most active branches, while manufacturing (B81C), digital processing (G06F), and geophysics (G01V) each account for small shares — signaling areas where the interface design space remains less worked.

What the competitive structure means for R&D investment
Four structural observations emerge from the evidence: a maturing lifecycle, a tiered competitive field, a focused cross-institutional collaboration, and a heavily US-centric jurisdiction profile.
Field has plateaued near its 2023 peak
The lifecycle evidence places MEMS-ASIC interface technology at Maturity, with annual filings having plateaued near the 2023 peak of 19. On a multi-year basis the field still shows positive growth (8% recent growth), but incremental acceleration sensing architectures are well covered. New IP value is more likely to emerge from underserved adjacent branches than from the crowded core.
Lifecycle: MaturityTwo-tier structure leaves room for focused challengers
InvenSense (34 patent records) and Merlin Tech (23 patent records) form a clear first tier, with Analog Devices (20), Honeywell International (14), and PGS Geophysical (8) constituting a credible second tier. New entrants — including MEI Micro and STMicroelectronics — are entering with fresh filings, suggesting that the second tier is still contestable for organizations with differentiated interface architectures.
Moderate concentrationA single notable co-filing pair: A*STAR and PGS Geophysical
The Agency for Science, Technology and Research (A*STAR, Singapore) and PGS Geophysical have co-filed 8 patent records together, making them the only documented collaborative pair in the evidence. This pairing combines geophysical sensing application expertise with Singapore’s applied research capability, pointing to seismic MEMS sensing as a focused joint development axis. No other cross-institutional co-filing is recorded in the evidence.
Targeted collaborationUS-centric filing with selective EPO and PCT coverage
The United States is the primary jurisdiction with 115 patent records, followed by Europe via EPO (42) and WIPO PCT (21). India (14) and China (12) show meaningful but limited coverage, while Singapore, Australia, Canada, Germany, the United Kingdom, South Korea, and Austria each account for small counts. Organizations seeking broad freedom to operate outside the US will find relatively thin coverage in major Asian manufacturing markets.

Co-filing pairs, ranked by the number of jointly-filed patent families.
InvenSense leads in inertial sensing; Merlin Tech and STMicroelectronics are the most active new entrants
The top-ranked filers span consumer inertial sensing, defense/aerospace, analog semiconductors, and geophysics — indicating that MEMS-ASIC interface IP is being built across multiple end-market verticals rather than a single application.
InvenSense Inc
InvenSense holds 34 patent records, the largest position in the field, concentrated in G01P velocity and acceleration (32 records at the G01P 15 subclass) and B81B MEMS microstructure (7 records). Recent momentum shows a 31% decline versus the prior period, suggesting the company’s foundational portfolio is maturing rather than actively expanding — creating a potential window for challengers.
34 patent recordsMerlin Tech Inc
Merlin Tech ranks second with 23 patent records and enters the recent period as a new entrant with 4 recent filings, indicating active portfolio construction. Its technology emphasis spans G01P 15 (velocity and acceleration, 23 records) and G01V 7 (geophysics and gravity surveying, 4 records), suggesting a differentiated positioning that bridges inertial sensing and geophysical applications — a combination that overlaps with the A*STAR/PGS collaboration axis.

Navigation/gyroscopes and MEMS manufacturing are the least-worked adjacent branches
Several IPC branches adjacent to the dominant inertial sensing core have low absolute counts and share, making them observable as underserved areas. Entry plausibility depends on technical proximity and application pull.
G01C · Distance, navigation & gyroscopes
With 35 patent records and an 8% share of the technology composition, G01C is the most active of the sparse adjacent branches but remains well below the dominant G01P class. Cambridge Enterprise’s focus on G01C 19 (gyroscopes) and Texas Instruments’ emphasis on G01C 21/22 (navigation) indicate that established players are present but not prolific. For teams working on MEMS-ASIC interface design for navigation-grade gyroscopes or inertial navigation systems, this branch offers a less crowded filing environment relative to accelerometry.
Search this in Eureka →B81C · MEMS manufacturing
B81C (MEMS manufacturing processes) accounts for only 14 patent records and a 3% share, despite being technically foundational to any MEMS-ASIC integration architecture. Process-level IP covering wafer bonding, through-silicon vias, or heterogeneous integration specific to the MEMS-ASIC boundary is sparsely represented. Organizations with process technology capability — particularly in advanced packaging or monolithic integration — may find limited prior art to contend with in this branch.

Frequently asked questions
InvenSense Inc holds the top position with 34 patent records, ahead of Merlin Tech Inc (23) and Analog Devices Inc (20). InvenSense’s portfolio is concentrated in velocity and acceleration sensing (G01P 15) and MEMS microstructure (B81B), reflecting its focus on consumer and industrial inertial measurement units.
Annual filing counts grew from 9 in 2017 to a peak of 19 in 2023, then eased to 13 in 2024. The 2025 and 2026 figures are subject to publication lag and should not be read as a real decline. The overall multi-year picture is one of a field that expanded through the early 2020s and is now plateauing at a mature level.
G01P (velocity and acceleration sensing) is the dominant branch by a wide margin, followed by B81B (MEMS microstructure), G01C (navigation and gyroscopes), B81C (MEMS manufacturing), and G06F (digital data processing). The concentration in G01P reflects the field’s center of gravity in MEMS accelerometer and inertial sensing architectures.
The evidence identifies one documented co-filing pair: the Agency for Science, Technology and Research (A*STAR, Singapore) and PGS Geophysical, with 8 co-filed patent records. This collaboration appears focused on geophysical MEMS sensing applications. No other cross-institutional co-filing pairs are recorded in the available evidence.
The United States is the primary filing jurisdiction with 115 patent records, followed by Europe via EPO (42) and WIPO PCT (21). India (14) and China (12) show notable but limited coverage. Coverage in major Asian manufacturing markets remains comparatively thin.
G01C (navigation and gyroscopes, 35 patent records, 8% share) and B81C (MEMS manufacturing, 14 patent records, 3% share) are the most technically proximate branches with relatively low filing density. G06F (digital data processing, 11 records), H10D (semiconductor devices, 8 records), and G01V (geophysics, 7 records) are also sparse. These are observations of relative sparsity; whether they represent actionable entry points depends on an organization’s specific technical capability and application focus.
