The dual leadership by a Singapore-registered EV startup and a major US automaker suggests that both emerging-market entrants and established OEM-adjacent entities see commercial relevance in this space, potentially from different application angles — power electronics for two-wheelers versus automotive thermal management.
Filing counts for 2024 and 2025 are likely understated due to standard patent publication lag; the apparent peak in 2024 should be interpreted cautiously. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Annual filings are rising, with power conversion and EV propulsion dominating the technology mix
The filing trend and technology composition charts together show a field that has moved from intermittent early activity to a more consistent growth trajectory, concentrated in a few core IPC branches.
Annual filing trend
Activity was sparse and irregular from 2017 through 2023, with no filings in 2017 or 2021. A notable step-up appears in 2024 with 5 records — the single highest annual count — consistent with the lifecycle assessment of a growing field. The 2025 and 2026 counts of 1 each reflect publication lag and should not be read as a slowdown.

B60L (electric vehicle propulsion) and H02M (power conversion) each account for 10 records, forming the visible technical core. H02P (motor and generator control) adds 5 records and H05K (printed circuits and assemblies) adds 4, reflecting hardware integration concerns. Several adjacent branches — B60M, G01R, H02G, H02J, B60W, B61C — each carry 2 or fewer records, marking the outer boundary of current activity.

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.
Matter Motor Works Pte Ltd
Matter Motor Works holds 4 patent records and is classified as a new entrant with an upward momentum trend. Its technical focus spans electric and magnetic measurement (G01R 31) and power conversion sub-classes (H02M 1 and H02M 5), indicating a hardware-level approach to inverter diagnostics and power stage design. As a Singapore-registered EV-focused entity, its filings reflect product development rather than platform-level IP.
4 patent recordsFord Global Technologies LLC
Ford Global Technologies also holds 4 patent records and concentrates on EV propulsion sub-classes B60L 15 and B60L 3, alongside printed circuits and assemblies (H05K 7). This combination suggests thermal management and packaging integration for automotive-grade traction inverters. Ford’s presence via its IP subsidiary signals a systematic rather than exploratory filing posture in this domain.
4 patent recordsFrequently asked questions
The current corpus covers 16 patent families in scope. This is a small but actively growing field, with the most recent filing years likely understated due to patent publication lag.
Matter Motor Works Pte Ltd and Ford Global Technologies LLC are joint leaders, each holding 4 patent records. Malaviya National Institute of Technology Jaipur ranks third with 2 patent records. All remaining ranked applicants hold 1 patent record each.
India is the lead filing jurisdiction with 8 patent records, followed by the United States with 5 and China with 3. WIPO (PCT) accounts for 1 record, indicating limited multi-jurisdictional protection filings to date.
The evidence places traction inverter control in the Growth stage. Annual filings are still rising, and the most recent years are understated by publication lag. The 100% recent growth rate supports this assessment.
B60L (electric vehicle propulsion) and H02M (power conversion) each account for 10 patent records, forming the technical core. H02P (motor and generator control) and H05K (printed circuits and assemblies) are secondary branches. Several adjacent branches carry 2 or fewer records.
No co-applicant relationships are detected in the current corpus. All filings have been made by individual applicants — corporate, academic, or individual inventors — without recorded cross-institution collaborations.

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.
