GaN Integrated Sensing Patent Snapshot 2026
GaN integrated sensing is a highly concentrated, early-stage niche in which the top five filers account for 90% of the leading filers’ combined output and the United States dominates as both the primary filing and innovation jurisdiction. Annual volume peaked in 2021 and has eased since, leaving the field in a post-peak phase with meaningful room for new entrants in adjacent sensing and transmission branches.
Navitas Semiconductor leads a tightly held, US-centric niche
Navitas Semiconductor holds the top position with 3 patent families, followed by GaN Systems and Infineon Technologies Austria, each with 2 patent families. The six ranked filers span both fabless power-IC specialists and established semiconductor conglomerates.
The top five filers together represent 90% of the ranked applicants visible in this query’ combined total, signaling an exceptionally concentrated visible assignee structure with little mid-tier activity. The gap between the leader and the field is narrow in absolute terms but significant relative to the corpus size.

The leaders’ positions reflect a focus on power-device integration rather than discrete sensing circuitry, suggesting that integrated sensing functionality within GaN power ICs remains an emerging, contested sub-field rather than a mature commodity.
The most recent filing years are subject to publication lag and likely undercount actual activity; conclusions about recent trajectory should be read with that caveat in mind. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2021 filing spike followed by easing volume, dominated by semiconductor device classes
The annual filing trend reveals a sharp burst of activity in 2021 followed by a step-down, while the technology composition chart shows that semiconductor device classification (H01L) anchors virtually the entire corpus with power conversion and pulse-logic classes as secondary themes.
Annual filing trend
Filings were negligible from 2017 through 2020, surged to a peak of 6 families in 2021, then declined to 2 in 2022 and 1 in 2023. Years 2024–2026 reflect publication lag and should not be read as confirmed zero activity; the true post-2023 level is not yet observable.

H01L (Semiconductor devices) covers all 10 families, confirming that device-level integration is the defining technical axis. H10D (Semiconductor devices — general), H02M (Power conversion), and H03K (Pulse technique and logic circuits) form a secondary cluster, while G01R (Electric and magnetic measurement), H01J, H03H, H04B, and H10N each appear in only one family, marking the sparse sensing-specific and transmission branches.

HIGH ACCURACY CURRENT SENSING FOR GaN POWER SWITCH…
High accuracy current sense circuitry for power switching devices comprising GaN power transistors provides for current feedback functions, e.g. current loop control, over-current protection (OCP) and short-circuit protection (SCP). The current sense circuitry comprises a current mirror sense GaN transistor (Sense_GaN) and a power GaN transistor (Power_GaN)… (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.

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.
Navitas Semiconductor
Navitas Semiconductor holds 3 patent families, the largest share in this corpus, concentrated in H01L 23 and H01L 25 — semiconductor packaging and multi-component assemblies — with one family in H01L 31. This positions the company as the leading filer in integrated GaN package-level sensing. No momentum data is available for Navitas in the recent-versus-prior comparison, suggesting its core filings predate the tracked momentum window.
families: 3Infineon Technologies Austria
Infineon Technologies Austria holds 2 patent families and is flagged as a new entrant in the recent filing window, indicating its GaN integrated sensing activity emerged in the most recent period rather than earlier. Its technical focus spans H01L 29, H10D 30, and H10D 62 — transistor structures and general semiconductor devices — differentiating it from Navitas’s packaging emphasis.
families: 2Frequently asked questions
The evidence scope covers 10 patent families in GaN integrated sensing. This is a small corpus reflecting the field’s nascent commercial status.
Navitas Semiconductor holds the most patent families in this field with 3, followed by GaN Systems and Infineon Technologies Austria with 2 each.
Nine of the patent records are filed at the United States patent office. One record is filed at the European Patent Office. No Asian jurisdictions appear in the current corpus.
The field is classified as post-peak. Annual filings peaked at 6 families in 2021 and have eased since. The overall corpus remains small in absolute terms, so this post-peak signal reflects a short activity burst rather than a long maturation cycle.
No co-applicant or joint-filing activity is recorded in the current evidence. All patent families appear to have been filed independently by individual entities.
Five branches each hold only one patent record: G01R (electric and magnetic measurement), H01J (electron and discharge tubes), H03H (impedance networks and filters), H04B (transmission), and H10N (other electric solid-state devices). These represent the sparsest areas relative to the visible H01L semiconductor device classification.

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.
