GaN Inverter Design Patent Snapshot 2026
The captured corpus for GaN inverter design is very small, with two patent families filed by two applicants split evenly between India and the United States. Activity peaked in 2021 and has eased since, placing the field in a decline stage within this evidence set — though the corpus size suggests broader evidence snapshot work is warranted before drawing strategic conclusions.
Two applicants share the entire top-100 ranking equally
Within this evidence set, Ecole Centrale School of Engineering at Mahindra University and Magna International each hold one patent family, together accounting for the entirety of the top-filer pool.
The top five filers’ share of the ranked applicants visible in this query stands at 100%, indicating a completely undifferentiated concentration tier — there is no second tier at all in the current corpus.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Ecole Centrale School of Engineering, Mahindra University | 1 | |
| 2 | Magna International Inc. | 1 |
The equal split between an academic institution and a Tier-1 automotive supplier suggests the filed IP covers both foundational circuit research and application-oriented motor-drive integration, with no single visible commercial player visible at this scale.
Because this corpus contains only two patent families, conclusions should be treated as provisional. Broader searches across GaN power electronics may surface additional relevant filings not captured here. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2021 filing marks the only historical activity, with a 2026 entry extending the record
The annual trend and technology composition together show a field with minimal filing history concentrated in power-conversion and pulse-technique IPC classes.
Annual filing trend
One family was filed in 2021 and one appears in 2026; all intervening years show zero activity. The 2026 entry falls within the publication-lag window and may not yet reflect its full citation or family context.

H02M (power conversion) and H03K (pulse technique and logic circuits) each appear twice at the patent-record level, with H02P (control of motors and generators) appearing once — indicating that gate-drive logic and AC/DC conversion are the primary technical anchors in the corpus.

A switching circuit of a motor drive includes a high-side switch configured to selectively conduct current between a DC positive conductor and an output conductor, and a low-side switch configured to selectively conduct current between the output conductor and a DC negative conductor. The high-side switch comprises a depletion mode (D-Mode) gallium nitride… (excerpt from the patent abstract)

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.
Ecole Centrale School of Engineering, Mahindra University
Holds one patent family with IPC focus on H02M 1 (power conversion front-end), H02M 7 (inverter topology), and H03K 17 (electronic switches and gate drivers). The combination suggests foundational circuit-level research into GaN switching behavior and driver integration, consistent with an academic research profile.
families: 1Magna International
Holds one patent family with IPC focus on H02M 7 (power conversion / inverter), H02P 29 (motor protection and control), and H02P 3 (braking and dynamic control). This application-layer emphasis — linking GaN inverter hardware to motor control outcomes — reflects Magna’s electric-vehicle drivetrain orientation. Applicant momentum data is not available.

The evidence covers 2 patent families in scope. This is a very small corpus and findings should be validated against broader GaN power-electronics searches before informing major strategic decisions.
Within this evidence set, Ecole Centrale School of Engineering at Mahindra University and Magna International each hold one patent family and are the only ranked applicants.
Patent records in this corpus are filed in India and the United States — one record in each jurisdiction. Major GaN markets in East Asia and Europe are not represented in this evidence set.
The lifecycle evidence classifies the field as Decline within this corpus, with annual filings easing back from the 2021 peak. The 2026 filing falls within the publication-lag window and does not yet indicate a reversal of that trend.
H02M (power conversion, including AC/DC and inverter topologies) and H03K (pulse technique and logic circuits) each appear twice at the patent-record level. H02P (control of motors and generators) appears once. These three classes together cover the full corpus.
No co-applicant or joint filing relationships are recorded in the collaboration evidence. The two applicants have filed independently, with no consortium or university-industry co-assignment visible in this corpus.

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.
