MEMS Gyroscope Fabrication Patent Snapshot
The Regents of the University of California leads a small, academically anchored corpus of 5 patent families, with the top five filers holding a commanding share among the largest filers. The field is in a decline stage following a modest peak, with annual volume easing and filing activity sparse across most technology branches.
University of California leads a concentrated, niche corpus
The Regents of the University of California ranks first among all applicants, reflecting the strong academic character of MEMS gyroscope fabrication patent activity. Honeywell International and Atlantic Inertial Systems are the principal industrial participants in the ranking.
The top five filers account for 56% of the combined total among the ranked applicants visible in this query, indicating a highly concentrated field where a handful of institutions define the competitive frontier. The gap between the leader and the remaining applicants is narrow in absolute terms but significant relative to the corpus size.

The dominance of academic and semi-academic filers suggests that core fabrication innovations remain closer to research output than to high-volume industrial prosecution, which may indicate room for industrially focused players to build differentiated positions.
The most recent filing years are subject to publication lag and should be interpreted cautiously; apparent activity in 2024–2026 may not yet reflect the full volume of filings made in that period. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sparse annual filings concentrated in navigation and MEMS device classes
The filing trend and technology composition together reveal a niche, navigation-anchored field whose activity peaked modestly and has since eased, while the branch mix is dominated by two core IPC classes.
Annual filing trend
Annual filing volume has been low throughout the observed window, with a modest peak visible around 2018 and subsequent easing. Years closest to the present remain subject to publication lag and should not be read as definitive.

G01C (distance, navigation and gyroscopes) and B81B (microstructural MEMS devices) together account for the large majority of classified records, confirming that the corpus is tightly focused on core gyroscope sensing and device architecture. Adjacent branches such as B81C (MEMS manufacturing), H01L (semiconductor devices), and H03H (impedance networks and filters) are each represented by only a handful of records.

Increasing the dynamic range of a MEMS gyroscope
A MEMS gyroscope system and method for increasing a dynamic range of the MEMS gyroscope is provided. By adjusting a scale factor of the MEMS gyroscope, the highest sensed rate will be increased, which increases the dynamic range. The scale factor is adjusted by using a variable sense bias and/or an automatic gain control loop in sense electronics. (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. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
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.
University of California
The Regents of the University of California leads with 5 patent records, with technology emphasis spanning B81B microstructural MEMS devices and G01C gyroscope and navigation classes, plus a presence in G01P velocity and acceleration. No applicant momentum data is available for this corpus, so trajectory cannot be quantified. The collaboration record shows inventor-led co-filings with Andrei M. Shkel and Cenk Acar.
patent records: 5Honeywell International
Honeywell International holds 3 patent records, focused primarily on G01C gyroscope and navigation, with secondary coverage in B81B microstructural devices and H03B oscillation generation — the only applicant in the corpus with a documented oscillation generation emphasis. This mix reflects Honeywell’s industrial orientation toward sensor integration and signal conditioning alongside core MEMS structure.
patent records: 3Frequently asked questions
The Regents of the University of California leads with 5 patent records, ahead of Hasan Dogan Gavcar and Honeywell International, each with 3 records, and Atlantic Inertial Systems and Andrei M. Shkel, each with 2.
The field is classified as Decline. Annual filing volume has eased back from a modest peak, indicating that the most active prosecution period for core fabrication concepts has passed.
The United States is the lead jurisdiction. Canada, Europe (EPO), and WIPO (PCT) each appear as secondary destinations, followed by China, Japan, Australia, India, and Turkey.
G01C (distance, navigation and gyroscopes) and B81B (microstructural MEMS devices) are the visible classes. B81C (MEMS manufacturing), H01L (semiconductor devices), and H03H (impedance networks and filters) appear at lower density.
The ranking is led by academic and inventor-individual filers, with the University of California at the top and named inventors such as Hasan Dogan Gavcar and Andrei M. Shkel prominent. Honeywell International and Atlantic Inertial Systems are the principal industrial participants.
The most active co-filing pairs both involve the Regents of the University of California: Andrei M. Shkel co-filed on 2 records with the university, as did Cenk Acar. No cross-industry joint filings are evident in the available 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. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
