Conductive Functional Fiber Patent Snapshot 2026
The conductive functional fiber patent space is small and fragmented, with 7 patent families spread across eleven applicants — no single player holds more than one family. Activity is in a growth phase, with filings accelerating in the most recent window, though the corpus remains early-stage and China-concentrated.
Fragmented field with no dominant incumbent — China leads filings
The corpus spans 7 patent families across eleven applicants, none holding more than 1 patent record each. Beijing Institute of Clothing Technology sits at the top of the ranking but is tied with every other filer, indicating a genuinely flat visible assignee structure with no entrenched leader.
The top five filers account for 45% of the ranked applicants visible in this query’ combined total — a moderate concentration figure for such a small corpus, reflecting how evenly distributed the limited activity is. There is no detectable tier gap between a lead cluster and challengers.

The absence of a visible assignee means freedom-to-operate is relatively open, and early movers who consolidate position across multiple IPC branches could establish a defensible portfolio quickly. Academic and research-institute entrants (Beijing Institute of Clothing Technology, Xi’an Polytechnic University) suggest the field is still transitioning from lab to commercialization.
The most recent 18–24 months of filings are likely under-counted due to standard patent publication lag; the current totals should be read as a floor, not a ceiling. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Growth-phase trajectory anchored in chemical filament and fibre science
Two lenses — annual filing cadence and IPC branch distribution — together show a nascent but accelerating field whose technical foundation is firmly in fibre chemistry, with secondary threads in spinning, yarn, and weaving.
Annual filing trend
Filings were sparse but steady from 2017 through 2022, then stepped up to 2 records in 2024 before a partial 2025 entry. The recent-window growth rate of 200% reflects the move from near-zero to low-single-digit annual volume. Treat 2025–2026 counts as understated due to publication lag; the real trajectory is likely stronger than the chart tail suggests.

D01F (Chemical filament and fibre features) accounts for all 7 patent records, making it the indisputable core branch. D01D (Man-made filament spinning), D02G (Yarn texturing and crimping), and D03D (Woven fabrics and weaving) each appear in 3 records, indicating that some applicants are pursuing integrated fibre-to-fabric claims. D06B, D06M, and G06F each appear in only 1 record, marking them as sparse adjacencies.

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.

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.
Beijing Institute of Clothing Technology
Beijing Institute of Clothing Technology (also appearing in the corpus as a co-applicant with Masui Textile Fibers, Shandong) holds 1 patent record focused on D01F chemical filament and fibre features. The collaboration with an industry partner points toward technology transfer intent. As an academic institution, its trajectory depends on whether it converts research output into additional filings — evidence marks the partnership-linked record as a new entrant signal.
families: 1Chongqing Graphene Research Institute
Chongqing Graphene Research Institute holds 1 patent record covering both D01F 1 and D01F 6 subclasses, co-filed with Chongqing Zhongke Enway Technology. This pairing around graphene-based conductive fibre composition is the most technically specific cluster in the corpus. Both entities are new entrants, and their shared graphene focus aligns with the corpus’s most-cited prior art on oriented graphene-oxide–carbon-nanotube conductive fibres.
families: 1Frequently asked questions
The corpus stands at 7 patent families. This is a small, early-stage field and the count should be treated as a floor given publication lag on the most recent filings.
Beijing Institute of Clothing Technology ranks first by the applicant list but holds only 1 patent record — the same as every other applicant in the corpus. There is no visible incumbent; leadership is effectively tied across eleven applicants.
China accounts for 6 of the 9 jurisdiction-level records, making it the visible filing location. Europe (EPO), South Korea, and the United States each hold 1 record, indicating that non-Chinese coverage is sparse.
The evidence classifies conductive functional fiber as Growth stage. Annual filings are still rising and recent-year counts are understated by publication lag, so the field has not yet reached a maturity plateau.
D01F (Chemical filament and fibre features) is the most covered branch, appearing in all 7 patent records. D06B (Textile wet treatment), D06M (Textile chemical treatment), and G06F (Electric digital data processing) are the least covered, each appearing in only 1 record.
Two co-applicant pairs are recorded: Chongqing Graphene Research Institute with Chongqing Zhongke Enway Technology, and Masui Textile Fibers (Shandong) with Beijing Institute of Clothing Technology. Both pairings link research institutes or specialized labs with industrial partners, which is typical of early commercialization activity.

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.
