Hardware Security (Device-Level) Patent Snapshot 2026
The retrieved corpus for hardware security at the device level is extremely narrow, with a single patent family on record filed in 2023, held exclusively by eMemory Technology Inc. Given publication lag and likely search-scope constraints, this snapshot should be treated as a starting point rather than a complete market picture.
eMemory Technology holds the sole position in this retrieved corpus
eMemory Technology Inc ranks first — and only — in the current applicant ranking, accounting for the entirety of the top five filers’ share of the ranked applicants visible in this query in this corpus.
With a single patent family on record, no tier structure or concentration gradient can be assessed; the corpus is entirely undifferentiated at this point.

eMemory Technology’s focus on one-time-programmable memory security elements — spanning static and digital memories, semiconductor devices, protective circuit arrangements, and memory device manufacture — positions it as the sole documented filer in this narrowly scoped retrieval.
The most recent roughly 18–24 months of filings are subject to publication lag and are likely under-counted; the 2023 single filing may therefore represent a larger underlying activity level than the corpus currently reflects.
A single 2023 filing anchors a minimal but technically diverse corpus
The annual filing trend and technology composition charts together indicate a very sparse corpus — one patent family filed in 2023 — with IPC coverage spanning four adjacent semiconductor and memory classes.
Annual filing trend
Activity registers as a single filing in 2023, with zero entries in all other years from 2017 to 2026. Years from 2024 onward are subject to publication lag and should not be read as confirmed zero activity.

The one family in scope maps across four IPC branches: G11C (static and digital memories), H01L (semiconductor devices), H02H (protective circuit arrangements), and H10B (memory device manufacture), reflecting the multi-class nature of device-level security IP.

An OTP memory cell includes an antifuse transistor, a first transistor and a second transistor. The antifuse transistor includes a first fin, a second fin, a first gate structure, a first drain/source contact layer and a second drain/source contact layer. A central region of the first fin and a central region of the second fin are covered by a first gate… (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.
eMemory Technology Inc
eMemory Technology holds 1 patent family in this corpus, filed in 2023. Its momentum trend is flagged as a new entrant in the retrieved window. Technology emphasis spans G11C 16, G11C 17, and G11C 5 — all within static and digital memories — consistent with the firm’s established IP in OTP and multi-time-programmable memory cells used for hardware root-of-trust and anti-clone applications.
families: 1No second-ranked applicant
The current corpus contains only one applicant. A challenger tier cannot be identified from the available evidence. Expanding the search scope or broadening the IPC filter is recommended to surface competing filers in adjacent hardware security domains.
families: N/AFrequently asked questions
The retrieved corpus contains 1 patent family. This is a very narrow result set and likely reflects a tightly scoped search query rather than the full extent of global hardware security IP activity.
eMemory Technology Inc is the sole ranked applicant, holding 1 patent family filed in 2023. Its technology focus spans static and digital memory classes relevant to OTP-based hardware security primitives.
Four IPC classes are represented: G11C (static and digital memories), H01L (semiconductor devices), H02H (protective circuit arrangements), and H10B (memory device manufacture). All four map to a single patent family.
The single patent family in this corpus is filed through the United States. No other national or regional offices appear in the current evidence set.
The life-cycle stage cannot be determined from the current evidence; the corpus is too small to produce a reliable growth-rate or saturation signal. A broader search is needed to characterize field maturity.
No co-applicant or collaboration relationships are documented in the current evidence set. The sole filing is attributed to eMemory Technology Inc alone.

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. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
