Conductive Fiber Continuous Spinning Patent Snapshot
The conductive fiber continuous spinning patent space is a small, highly concentrated field in decline, with the Korea Electrotech Research Institute holding the dominant position. Filing activity peaked in 2018 and has been sparse since, signaling an early-stage niche that has not yet attracted broad industrial competition.
Korea Electrotech Research Institute leads a tightly concentrated field
The Korea Electrotech Research Institute is the clear leader, holding 2 patent records — the most of any applicant — followed by five additional filers each holding 1 patent record: Honeycomb Battery Co, South. China University of Technology, King Abdullah University of Science and Technology, Donghua University, and Dong-A University Research Foundation for Industry-Academy Cooperation.
Concentration is extreme: the top five filers account for 86% of the combined total among the ranked applicants visible in this query. This tier structure leaves virtually no mid-tier challenger cluster and indicates that the field has not yet attracted scale investment from large industrial players.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | Korea Electrotech Research Institute | 2 | |
| 2 | Honeycomb Battery Co | 1 | |
| 3 | South China University of Technology | 1 | |
| 4 | KING ABDULLAH UNIV OF SCI & TECH | 1 | |
| 5 | Donghua University | 1 | |
| 6 | Dong-A University Research Foundation for Industry-Academy Cooperation | 1 |
The leaders’ positions suggest an early, research-driven phase dominated by academic and government research institutes rather than commercial manufacturers. Entry barriers from incumbents are low given the small portfolio sizes, but the thin filing base also means limited prior art to design around.
Filings from approximately 2024 onward are subject to publication lag and likely under-represent true activity; the trend data for those years should be interpreted with caution. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sparse, irregular filings dominated by fiber chemistry and spinning process classes
The annual filing trend reveals an intermittent, low-volume pattern since 2017, while the technology composition shows that chemical filament and fiber features (D01F) and man-made filament spinning (D01D) account for the largest share of classified records.
Annual filing trend
Activity peaked in 2018 with 2 filings and has been irregular at best — 1 filing each in 2019, 2021, and 2024, and zero in all other years. This pattern confirms a field that has not sustained momentum. Years from 2024 onward are subject to publication lag and should not be read as confirming a structural decline.

D01F (Chemical filament and fibre features) is the most represented class with 7 records, followed by D01D (Man-made filament spinning) with 5. Secondary clusters appear in inorganic chemistry (C01B), polymer processing (C08J), and polymer additives (C08K), each with 2 records. Peripheral classes — including nanotechnology (B82Y), nonwovens (D04H), and battery applications (H01M) — each hold 1 record, illustrating how researchers are linking fiber spinning to adjacent functional domains.

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.
Korea Electrotech Research Institute
The Korea Electrotech Research Institute holds 2 patent records — the largest single portfolio in this corpus. Its technical emphasis spans inorganic chemistry (C01B, covering non-metallic elements and inorganic compounds), polymer processing (C08J), and polymer additives (C08K), suggesting a focus on material-science foundations of conductive fiber rather than the spinning process itself. No recent momentum trend is reported, consistent with the field’s broader decline.
patent records: 2Donghua University
Donghua University holds 1 patent record and is the only applicant flagged as a new entrant with a rising trend. Its technical focus is concentrated in man-made filament spinning (D01D) and chemical filament and fibre features (D01F), aligning directly with the core spinning process. As one of China’s leading textile-focused research universities, its entry could signal renewed academic interest in the space.
patent records: 1Frequently asked questions
The evidence set covers 5 patent families in scope for conductive fiber continuous spinning globally.
The Korea Electrotech Research Institute leads with 2 patent records, ahead of five other applicants — Honeycomb Battery Co, South China University of Technology, King Abdullah University of Science and Technology, Donghua University, and Dong-A University Research Foundation for Industry-Academy Cooperation — each holding 1 patent record.
The United States is the primary filing jurisdiction with 4 patent records, followed by China with 2 and South Korea with 1.
The field is classified as Decline, with annual filings easing back from the 2018 peak. Activity has been intermittent, with zero filings in most years since 2018.
D01F (Chemical filament and fibre features) is the most represented class with 7 records, followed by D01D (Man-made filament spinning) with 5. Secondary classes include C01B, C08J, C08K, D06M, G01B, and H01B, each with 2 records.
No co-applicant filings are detected in the current evidence set. All applicants appear to be filing independently, which may reflect both the small corpus size and the early-stage, fragmented nature of research activity in this niche.
