GaN Device Structure Optimization Patent Snapshot 2026
The GaN device structure optimization corpus is extremely small — just 3 patent families held equally across three distinct applicants — indicating a nascent and highly fragmented filing environment. Activity peaked in 2021 and has eased since, with the United States as the dominant jurisdiction.
Three applicants share leadership in an early-stage, fragmented field
China, and Global Communication Semiconductors LLC each hold 1 patent family, placing them in a three-way tie at the top of the applicant ranking.
With all three leaders holding identical family counts, there is no established tier gap or visible incumbent. The top five filers account for 100% of the ranked applicants visible in this query’ combined total, confirming that the corpus is too small for meaningful concentration analysis beyond this observation.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | GAN Systems Inc | 1 | |
| 2 | UNIV OF ELECTRONICS SCI & TECH OF CHINA | 1 | |
| 3 | Global Communication Semiconductors LLC | 1 |
The equal standing of all applicants means no single entity has established a defensible portfolio lead. Any organization entering with even a modest filing program could establish a credible position in this space.
The most recent filing periods carry publication lag and may undercount actual activity; the apparent absence of filings after 2022 should not be interpreted as a confirmed cessation of R&D. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity peaked in 2021 and is easing; semiconductor device class dominates
The annual filing trend and technology composition charts together reveal a short, concentrated burst of activity followed by a pullback, all concentrated within a single visible IPC branch.
Annual filing trend
Filings rose from zero to a peak of 2 families in 2021, fell to 1 in 2022, and show no recorded activity from 2023 onward. Given publication lag of 18–24 months, the 2024–2026 absence does not confirm a complete halt in filing activity.

A device includes a semiconductor die, a source contact, a drain contact, a first passivation layer, a T-shaped gate contact, a field plate, and a second passivation layer. The semiconductor die generally includes a plurality of semiconductor layers disposed on an insulating substrate. The source contact and the drain contact are electrically coupled to a… (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.
GAN Systems Inc
GAN Systems Inc holds 1 patent family and is the only applicant with cross-class coverage, spanning H01L 29, H10D 30, and H10D 62. Its applicant momentum is recorded as a new entrant in the recent period, suggesting this filing represents an initial stake rather than a consolidated position. The most-cited record in the corpus — ‘Device structure for power semiconductor transistor’ (4 citations) — is associated with this applicant’s representative patent US12027616B1.
families: 1Global Communication Semiconductors LLC
Global Communication Semiconductors LLC holds 1 patent family, focused exclusively on H01L 29 (Semiconductor devices). No momentum data is available for this applicant beyond its current standing. Its US-based filing aligns with the corpus’s visible jurisdiction, and its specialization in the core semiconductor device class positions it as a focused technical player in GaN transistor structures.
families: 1Frequently asked questions
The corpus contains 3 patent families in scope, held across three distinct applicants, each with 1 family.
GAN Systems Inc, the University of Electronic Science and Technology of China, and Global Communication Semiconductors LLC are tied at 1 patent family each. GAN Systems Inc has the broadest IPC coverage among the three.
Annual filing activity peaked in 2021 with 2 patent families recorded, falling to 1 in 2022. The lifecycle stage is assessed as Decline, with activity easing back from that peak.
Two patent records are filed in the United States and one in China. No filings are recorded in Europe, Japan, Korea, or via PCT within this corpus.
The most-cited record is titled ‘Device structure for power semiconductor transistor,’ with 4 citations. Its representative patent number is US12027616B1.
No co-applicant or joint-filing relationships are recorded in this corpus. All three applicants have filed 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.
