GaN Power Gate Drive Control Patent Snapshot 2026
The GaN power gate drive control space is highly concentrated, with GaN Systems Inc. holding a commanding position among a small group of filers that includes established semiconductor firms and emerging Chinese companies. Annual filing activity has been rising since 2021 and the field remains in a growth stage, though the total corpus is still modest, signaling early-stage competitive formation.
GaN Systems dominates a concentrated, early-stage field
GaN Systems Inc. leads the applicant ranking with 5 patent records, placing it well ahead of all other filers, each of whom holds a single patent record. The top five filers together account for 75% of the ranked applicants visible in this query’ combined total, confirming a sharply concentrated visible assignee structure.
There is a pronounced tier gap between the leader and the rest: GaN Systems Inc. holds five times the patent records of any single rival. The remaining applicants — Renesas Design (UK) Ltd., Xiamen University, Ecole Centennial School of Engineering Mahindra University, Chengdu ConvenientPower Semiconductor Co. Ltd., and Chengdu Yichong Wireless Power Technology Co. Ltd. — each contribute one patent record, forming a flat second tier with no clear challenger yet established.

GaN Systems Inc.’s concentration in H03K (pulse technique and logic circuits) alongside H01F and H01L indicates a vertically integrated approach spanning gate driver logic, magnetics, and device-level integration. The absence of a strong second-tier player leaves the assignee snapshot open for challengers willing to commit focused R&D resources.
Filing counts for the most recent 18–24 months are subject to publication lag and likely understate true activity; the apparent flattening in 2025–2026 should not be read as a slowdown. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity has grown since 2021 and technology is anchored in pulse and logic circuits
Two structural features define the field: a clear upward filing trajectory beginning in 2021 and a technology mix dominated by H03K (pulse technique and logic circuits), with secondary representation across power conversion and semiconductor device classes.
Annual filing trend
Filing activity was absent from 2017 through 2020, then initiated in 2021 with 2 records. Growth continued unevenly through 2026, reaching 2 records again in that year. The recent-window growth rate stands at 100%. As publication lag affects the last 18–24 months, the 2025 and 2026 figures should be treated as provisional minimums rather than final counts.

H03K (pulse technique and logic circuits) is the visible IPC class with 11 patent records, making it the clear technical core of this field. H02M (power conversion) follows with 5 records, reflecting integration with converter topologies. All remaining classes — B23B, B23Q, G01R, H01F, H01L, H02P, and H05B — each carry a single record, indicating sparse but diverse adjacent coverage.

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 5 patent records, all concentrated in H03K 17 (pulse technique and logic circuits), with single-record extensions into H01F 19 (magnetics and transformers) and H01L 23 (semiconductor devices). This breadth across driver logic, magnetics, and device integration reflects a platform-level approach. Applicant momentum data is not available for this entity in the recent-window comparison, but its accumulated lead is clear from the ranking.
patent records: 5Renesas Design (UK) Ltd.
Renesas Design (UK) Ltd. holds 1 patent record and is classified as a new entrant by momentum trend. Its technology emphasis spans G01R 31 (electric and magnetic measurement), H02M 1 (power conversion), and H03K 17 (pulse technique and logic circuits), suggesting a system-level integration angle that differs from GaN Systems Inc.’s logic-first approach. As a subsidiary of Renesas Electronics, it brings broader corporate resources that could accelerate filing activity.
