Conductive Fiber Washability & Durability Patent Snapshot
The patent corpus for conductive fiber washability and durability is extremely small, with activity concentrated in South Korea and dominated by a single incumbent. The field has reached a plateau, making it a relatively open frontier for new entrants with differentiated approaches.
NIHON SANMO DYEING leads a highly concentrated, nascent field
NIHON SANMO DYEING holds the top position among ranked applicants, accounting for the largest share of patent records in this corpus. The remaining filers — Suzhou Yibuku Textile, MYANT CORP, and Samjin Net — each hold a single record, underscoring how few organizations have committed dedicated IP to conductive fiber washability and durability.
The top five filers collectively account for the entirety of the ranked applicants visible in this query’ combined total, indicating extreme concentration with no meaningful second tier. There is no evidence of a challenger cluster forming at this time.

NIHON SANMO DYEING’s position, anchored in textile chemical treatment and garment applications, reflects a vertically integrated approach spanning fiber chemistry and end-product categories. This creates a broad but shallow prior-art footprint that new entrants could navigate around with a focused technical angle.
The most recent filing years are subject to standard publication lag and may undercount activity; this analysis should be treated as a directional snapshot rather than a definitive count. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sporadic filings and a textile-chemistry-dominant technology mix
Filing activity has been sparse and irregular across the observed window, while the technology composition is anchored in chemical treatment of textiles with adjacent threads in garment construction and conductor engineering.
Annual filing trend
Activity shows isolated spikes in 2019, 2024, and 2025, with no sustained upward run. The 2024 and 2025 data points should be interpreted cautiously given publication lag. The plateau is consistent with the field’s maturity stage rather than active growth.

D06M (textile chemical treatment) is the visible branch, appearing across all records. A41B (shirts, underwear and linen) and A47H (curtains and window fittings) reflect end-use application categories, while H01B (cables, conductors and insulators) signals electrical engineering crossover. D03D (woven fabrics and weaving) is the sparsest branch, appearing in only one record.

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.
NIHON SANMO DYEING
NIHON SANMO DYEING holds 2 patent records, the largest count among ranked applicants. Its technology focus spans A41B (shirts, underwear and linen), A47H (curtains and window fittings), and D06M (textile chemical treatment), indicating a broad application orientation across garment and interior textile categories. No momentum trend data is available for this applicant in the evidence.
patent records: 2Samjin Net
Samjin Net holds 1 patent record and is identified as a new entrant in the applicant momentum data. Its filing is concentrated in D06M (textile chemical treatment) sub-classes, suggesting a chemistry-first approach to conductive fiber durability. As a new entrant, its trajectory warrants monitoring even though its current portfolio is limited.
patent records: 1Frequently asked questions
The corpus currently contains 3 patent families in scope. This is a very small corpus, indicating that dedicated patent protection for washability and durability of conductive fibers remains limited relative to the broader e-textiles field.
NIHON SANMO DYEING holds the top position with 2 patent records, making it the single visible filer. All other ranked applicants — Suzhou Yibuku Textile, MYANT CORP, and Samjin Net — each hold 1 patent record.
South Korea is the primary filing jurisdiction, accounting for all 3 jurisdiction-level records at the lead position. China and WIPO (PCT) each appear once, reflecting limited international coverage in this corpus.
The evidence classifies this field as Maturity, with annual filings having plateaued near their historic level. The peak year on record is 2019. Subsequent filings have been sporadic, and the 2024–2025 data points remain subject to publication lag.
D06M (textile chemical treatment) is the visible branch, appearing across all 3 records. A41B (shirts, underwear and linen), A47H (curtains and window fittings), D01F (chemical filament and fibre features), and H01B (cables, conductors and insulators) each appear in 2 records. D03D (woven fabrics and weaving) is the sparsest branch at 1 record.
No co-applicant relationships are detected in this corpus. Every applicant has filed independently, with no evidence of consortium arrangements, university-industry partnerships, or joint-development filings.

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.
