Traction Inverter Topology Patent Snapshot 2026
The traction inverter topology patent space is in an early growth phase, with filings concentrated among a small set of academic and industrial entrants — three applicants are tied at the top with two patent records each. Activity has accelerated sharply in recent years from a near-zero base, with the United States as the dominant filing jurisdiction.
A nascent field with no single dominant industrial leader
The corpus stands at 7 patent families, with Malaviya National Institute of Technology Jaipur, Vitesco Technologies USA LLC, and Ford Global Technologies LLC each holding two patent records — a three-way tie at the head of the ranking.
The top five filers collectively account for 67% of the ranked applicants visible in this query’ combined total, indicating meaningful concentration at the top despite the small absolute corpus size. No single entity has pulled away from the pack, and the gap between the top tier and the remaining applicants is one patent record.

The presence of an Indian academic institution alongside established automotive-electronics suppliers suggests the field is attracting both foundational research and applied engineering activity simultaneously — an unusual dynamic typical of very early-stage technology areas.
Filing counts for the most recent 18–24 months are understated due to standard patent publication lag; the apparent activity level in 2024–2025 should be treated as a floor, not a ceiling. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity accelerating from a minimal base; power conversion dominates the IPC mix
Two charts capture the field’s trajectory and technical composition: annual filing volumes from 2017 to 2026 reveal when commercial interest emerged, while the IPC branch breakdown shows which engineering disciplines are driving claims.
Annual filing trend
Filings were essentially absent from 2017 through 2022, with activity materializing from 2023 onward and reaching a preliminary peak of three records in 2024. The 2025 and 2026 counts are understated by publication lag and should not be read as a slowdown.

H02M (power conversion — AC/DC etc.) is visible in the IPC mix, followed by B60L (electric vehicle propulsion) and H02J (power supply and grid systems). Lower-frequency branches including H05K (printed circuits and assemblies), B60K, B60W, H02K, and H02P represent thin but technically adjacent coverage.

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.
Malaviya National Institute of Technology Jaipur
Holds 2 patent records, with a new-entrant trajectory. Technology focus is concentrated in B60L 53 and B60L 55 (electric vehicle propulsion) and H02J 3 (power supply and grid systems), suggesting an orientation toward grid-integrated EV charging and V2G applications rather than pure inverter switching topology.
patent records: 2Vitesco Technologies USA LLC
Also holds 2 patent records with a new-entrant trajectory. Technology emphasis spans H02M 1 and H02M 7 (power conversion) and H02P 27 (motor control), indicating a focus on inverter modulation and drive-system integration — a commercially oriented complement to the academic research positioning of the co-leader.
patent records: 2Frequently asked questions
The corpus currently contains 7 patent families. This is a small but growing body of work concentrated in the United States and India, with the earliest filings appearing in 2019.
Malaviya National Institute of Technology Jaipur, Vitesco Technologies USA LLC, and Ford Global Technologies LLC each hold 2 patent records — a three-way tie for the lead position in the ranking.
H02M (power conversion — AC/DC etc.) is the visible IPC branch, reflecting the core inverter switching and conversion subject matter. B60L (electric vehicle propulsion) is the second most frequent branch.
The United States accounts for the most patent records, followed by India. No filings in Europe, China, Japan, or Korea appear in the current dataset, leaving major EV markets without coverage.
The lifecycle evidence classifies the field as Growth, with annual filings rising from zero through 2022 to a preliminary high in 2024. Recent years are understated by publication lag, so current activity is likely higher than recorded.
No co-applicant filings are detected in the current dataset. The absence of collaboration data may reflect the very small corpus size. All top-ranked applicants appear to be filing independently.

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.
