GaN Power Magnetics Patent Snapshot 2026
The GaN Power Magnetics corpus currently contains a single patent family on record, filed in 2025 and attributed to Tianjin Polytechnic University — indicating that this intersection of GaN power electronics and magnetic components is at the very earliest stage of formal IP activity. Competitive structure cannot yet be assessed, and the space is effectively open for technically capable entrants.
Tianjin Polytechnic University holds the sole filing on record
With only one patent family in scope, Tianjin Polytechnic University is ranked first by default, accounting for the entirety of filings among the largest filers in this corpus.
Concentration is technically absolute at this stage, but that reflects the nascent size of the corpus rather than a visible incumbent strategy — there is no meaningful tier gap to characterize.

The sole filer is an academic institution, suggesting that commercial players have not yet translated GaN power magnetics research into formal patent positions; this leaves the field structurally open.
The most recent filing period may be under-counted due to standard patent publication lag of 12–18 months; additional families filed in 2024–2025 may not yet be visible. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2025 filing marks the start of formal IP activity
The annual trend and technology composition together reflect a corpus at the very earliest stage: one filing appeared in 2025 against zero activity in the preceding eight years of the observation window.
Annual filing trend
No filings are recorded from 2017 through 2024; a single family appeared in 2025. The 2025 data point should be treated as a minimum bound given publication lag, and 2024 may also have unfiled or unpublished activity.

The sole family spans three IPC branches — magnets, inductors and transformers (H01F); power conversion (H02M); and photovoltaic/solar power generation (H02S) — indicating a cross-domain application of GaN-driven magnetic design, with solar power conversion as the apparent use case.

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.
Tianjin Polytechnic University
Tianjin Polytechnic University holds 1 patent family, covering the intersection of magnetic components (H01F 27), DC-DC power conversion (H02M 3), and power conversion front-end circuits (H02M 1). No prior-period filings exist, so momentum data is not available. As an academic institution it may license or spin out rather than commercialize directly.
families: 1No challenger on record
The corpus contains only one applicant; no second-tier or challenger position exists. Commercial players active in GaN power devices — who file extensively in adjacent IPC classes — have not yet registered families specifically in this intersection. That gap defines the challenger opportunity.
families: N/AFrequently asked questions
The corpus contains 1 patent family on record. This is a very early-stage count and is likely to grow as more filings from 2024–2025 clear the standard publication lag.
Tianjin Polytechnic University is the only applicant on record, holding the single patent family in scope. No commercial organization has yet registered a family in this specific intersection.
The sole family spans three IPC branches: H01F (magnets, inductors and transformers), H02M (power conversion including AC/DC and DC/DC), and H02S (photovoltaic and solar power generation), pointing to a solar power conversion application.
All recorded filings are in China only. No equivalent families have been filed under PCT or in the US, EP, JP, or KR patent systems based on current evidence.
The lifecycle stage cannot be formally determined from the available data. The first filing appeared in 2025 with no activity in the prior eight years, indicating a pre-commercial, nascent stage with no established trajectory.
The most observable gaps are in fixed inductors optimized for GaN MHz switching frequencies (H01F 17) and magnetics for GaN-based DC-AC inverters (H02M 7). Both are absent from the current corpus and are technically relevant to GaN power stage design. These observations should be validated with a broader prior-art search before directing R&D spend.

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.
