Nanosheet DTCO (GAA) Patent Snapshot 2026
The indexed corpus for Nanosheet DTCO (Gate-All-Around) technology currently contains a single patent family, filed in India by CVR College of Engineering in 2025, indicating that this precise intersection of nanosheet transistor design and design-technology co-optimization is at a very early stage of formal IP documentation. The competitive field is effectively open, with no established leaders, no cited prior art in the corpus, and no identified white-space candidates beyond the entire domain itself.
A single-applicant corpus signals an nascent IP field
CVR College of Engineering holds the sole patent family in this corpus, making it the de facto top-ranked applicant by default. No commercial semiconductor manufacturers, foundries, or EDA vendors appear in the current indexed set.
Concentration is absolute at this scale: the top five filers’ share of the ranked applicants visible in this query is 100%, though this reflects the absence of any other indexed applicants rather than a deliberate consolidation strategy by an incumbent.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | CVR College of Engineering | 1 |
The single filer’s position implies no meaningful competitive hierarchy exists yet. Any organization entering this space with a structured IP program would immediately become a top-tier rights holder relative to the current corpus.
The most recent filing period is subject to publication lag, meaning additional families filed in 2024–2025 may not yet be indexed; the true scope of early activity could be broader than this snapshot suggests. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity emerged in 2025; technology mix spans nanotechnology and semiconductor devices
The annual filing trend and technology composition together reveal a field where formal IP activity has only just appeared, anchored in two closely related IPC branches.
Annual filing trend
Zero activity is recorded from 2017 through 2024; one patent family appears in 2025. Given standard 18-month publication lag, filings from late 2024 onward may not yet be visible, so the 2025 data point should be read as a lower bound rather than a complete picture.

The single family is classified under both B82Y (Nanotechnology applications) and H01L (Semiconductor devices), reflecting the cross-disciplinary nature of nanosheet GAA work. No other IPC branches are represented, leaving the broader DTCO design-methodology space — process simulation, compact modeling, lithography co-optimization — entirely unoccupied in this corpus.

This invention presents a novel approach to the 3D stacking and integration of Gate-All-Around Field-Effect Transistors (GAAFETS) for next-generation mobile and AI semiconductor devices. Utilizing monolithic 3D integration and nanosheet/nanowire GAA -architectures, the invention enables ultra-high transistor density, improved electrostatic control, and… (excerpt from the patent abstract)

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.
CVR College of Engineering
CVR College of Engineering holds 1 patent family, classified under B82Y (Nanotechnology applications) and H01L (Semiconductor devices), filed in 2025 in India. No prior-period baseline exists in the corpus, so momentum cannot be quantified beyond the fact that this is a new entrant establishing the field’s first indexed record.
families: 1No challenger identified
No second-ranked applicant exists in the current corpus. The challenger position remains structurally vacant. Any organization filing in this technology intersection would immediately enter as a co-leader.
families: —Frequently asked questions
The evidence set contains 1 patent family. This is a very small corpus and should be interpreted cautiously; publication lag means additional families filed in 2024–2025 may not yet be visible in the index.
CVR College of Engineering is the sole indexed applicant, holding 1 patent family filed in India in 2025. No commercial semiconductor companies, foundries, or EDA vendors appear in the current corpus.
India is the only jurisdiction represented in the corpus, with 1 patent record. Major semiconductor IP markets — including the United States, South Korea, Europe, China, and Japan — show no indexed coverage at this scope.
The single family is classified under B82Y (Nanotechnology applications) and H01L (Semiconductor devices). Branches covering compact modeling, PDK development, lithography co-optimization, and design-rule checking specific to nanosheet nodes are absent.
A life-cycle stage cannot be determined from the evidence: a single 2025 filing is insufficient to establish a trend. The field should be treated as pre-emergence in IP terms, even though the underlying technology is industrially active at leading foundries.
No co-applicant or collaborative filings appear in the corpus. All indexed IP is attributed to a single applicant. Cross-organizational collaboration between foundries, equipment suppliers, and EDA vendors — typical in process node development — is not yet reflected in this indexed set.

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.
