GaN Power Simulation Patent Snapshot 2026
GaN power simulation is a highly concentrated, early-stage niche: a single firm, GaNPower International, holds the majority of the patent families in scope, with China and the United States as the only jurisdictions represented. Annual filing volume peaked in 2019 and has since eased, signalling a field in decline phase with limited but persistent activity from a small set of institutional entrants.
GaNPower International leads a tightly concentrated field
GaNPower International holds 4 of the 8 patent families in scope, placing it far ahead of every other filer. The remaining families are distributed among five distinct applicants — Beijing University of Technology, Beijing Microelectronics Technology Institute, GAC Aion New Energy Automobile, Shandong University, and Qingdao Jiaen Semiconductor — each contributing a single family.
The top five filers collectively account for 89% of the ranked applicants visible in this query’ combined total, indicating extreme concentration with no meaningful second tier. The gap between the leader and all challengers is substantial, reflecting the niche and specialist nature of GaN power simulation as a patenting domain.

GaNPower International’s dominance suggests it has been the primary commercial driver of formalized simulation IP in this space. The presence of two Chinese universities and one automotive OEM among the remaining filers points to emerging academic and industrial interest, but none yet approaches the leader’s footprint.
The most recent 18–24 months of filings are subject to publication lag and likely under-represent current activity; the apparent quiet in 2022–2023 and single-family counts in 2024–2026 should be interpreted with caution.
A 2019 spike, persistent low-level activity, and a semiconductor-device core
The filing trend reveals a sharp 2019 burst followed by sporadic single-family activity, while the technology composition is anchored in semiconductor device classes with adjacent signals in amplification and digital simulation.
Annual filing trend
Filings were absent before 2019, then spiked to four families in that year — all attributable to the visible applicant — before dropping to zero in 2020. Isolated single-family filings appear in 2021, 2024, 2025, and 2026, indicating residual but not sustained momentum. The most recent years are subject to publication lag and should not be read as a settled baseline.

Semiconductor devices (H01L) forms the visible branch, reflecting the device-level simulation focus. Amplifiers (H03F) and pulse/logic circuits (H03K) represent the analog circuit simulation layer, while electric digital data processing (G06F) and AI-based computing (G06N) point to emerging software-simulation and modeling approaches. Power conversion (H02M) appears as a secondary branch, consistent with GaN’s primary application in power electronics.

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.
GaNPower International
GaNPower International holds 4 patent families — half the entire corpus — with technology emphasis concentrated in semiconductor devices (H01L 27, H01L 29) and amplifiers (H03F 1). The associated inventors Fu Yue, Li Zhanming, and Liu Yan Fei share an identical technology focus, consistent with a tightly coordinated internal R&D team. Their activity was concentrated in 2019 with no subsequent filings visible in the trend data, which may reflect a deliberate staking of foundational claims.
families: 4Shandong University
Shandong University holds 1 patent family with a focus on semiconductor devices (H01L 29) and is identified as a new entrant based on recent filing momentum. As a research university, its entry signals growing academic interest in GaN simulation methodology. Its single-family position means it is not yet a commercial threat but could become a source of licensable foundational IP.
families: 1Frequently asked questions
The corpus contains 8 patent families in scope. This is a very small, specialist corpus reflecting the niche intersection of GaN device physics and simulation methodology.
GaNPower International is the visible filer, holding 4 of the 8 patent families in scope. The top five filers collectively represent 89% of the ranked applicants visible in this query’ combined total, indicating extreme concentration around a single commercial actor.
Patent records appear in only two jurisdictions: China, which holds the lead office position, and the United States. No European, Japanese, or Korean filings are present in the corpus.
The field is in a Decline stage, with annual filing volume easing back from its 2019 peak. Isolated single-family filings have continued in 2021, 2024, 2025, and 2026, but the sustained activity of the peak year has not recurred. Note that recent years are subject to publication lag.
Semiconductor devices (H01L) is the visible branch. Amplifiers (H03F) and pulse/logic circuits (H03K) form a secondary layer. AI-based computing models (G06N) and heterojunction devices (H10W) each appear only once, making them the sparsest branches in the current corpus.
One co-applicant relationship is documented: Beijing Microelectronics Technology Institute and Beijing University of Technology jointly filed one patent family. No other cross-entity collaborations are recorded in the evidence.
