Conductive Fiber Washability & Oxidation Durability Patent Snapshot
This is a small, specialized corpus that peaked in 2019 and has since seen minimal activity, with Federal Mogul Powertrain leading a fragmented field of automotive, textile, and electronics applicants. The United States is the primary filing office, and the dominant technical route centers on cable and conductor insulation rather than textile-first solutions.
Federal Mogul Powertrain leads a fragmented, low-volume field
Federal Mogul Powertrain holds the top position in the applicant ranking, followed by Teijin and Konica Minolta. The top five filers collectively account for 54% of the ranked applicants visible in this query’ combined total, indicating moderate concentration at the head of the ranking despite the overall small corpus size.
A visible tier gap separates Federal Mogul Powertrain and Teijin from the remaining applicants, most of whom hold only one or two patent records. This structure reflects a niche technology area where a small number of organizations have made sustained efforts while the broader market has largely remained on the sidelines.

The leaders’ positions span different technical emphases — cable-and-conductor insulation for Federal Mogul, chemical filament features and yarn texturing for Teijin — suggesting that no single technical approach has become the acknowledged standard, leaving room for differentiation.
The most recent filing years carry inherent publication lag and should be interpreted cautiously; apparent inactivity in 2023–2025 may partly reflect documents not yet published. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2019 peak followed by a sharp drop, with cable and conductor IP dominating the mix
The annual filing trend and technology composition charts together reveal both the temporal arc of this niche and the technical routes that have attracted the most formal IP protection.
Annual filing trend
Filing activity was negligible before 2018, surged briefly to its peak in 2019, then fell back sharply. No further activity is visible through 2024, with a single record appearing in 2025. Given publication lag of 18–24 months, the 2024–2025 period should not be read as confirming sustained absence of activity.

H01B (cables, conductors, and insulators) is the visible branch, followed by D01F (chemical filament and fibre features) and D06M (textile chemical treatment). Yarn texturing (D02G) and woven fabrics (D03D) each contribute a meaningful share, while printed circuits (H05K), layered products (B32B), and polymer processing (C08J) are present but at lower levels.

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.
Federal Mogul Powertrain
Federal Mogul Powertrain holds the top position with 8 patent records, concentrated in H01B (cables, conductors, and insulators) and D03D (woven fabrics and weaving). Their technical focus on protective sleeve constructions and shielded cable assemblies reflects an automotive and industrial wire-harness orientation rather than a wearables or e-textile approach. No momentum data is available for this applicant in the recent window.
8 patent recordsTeijin
Teijin ranks second with 6 patent records, with its portfolio centered on D01F (chemical filament and fibre features) and D02G (yarn texturing and crimping). This positions Teijin as the primary fiber-chemistry-oriented filer in the ranking, focused on how fiber composition and yarn structure affect conductivity retention under washing and oxidative stress. No recent-window momentum data is available for comparison.
6 patent recordsFrequently asked questions
The corpus covers 6 patent families in scope. This is a small, specialized niche, which means the assignee snapshot is easier to map in full but also that any new filing is likely to be visible to all active participants.
Federal Mogul Powertrain holds the top position with 8 patent records, focused primarily on cable, conductor, and insulator technologies (H01B) and woven fabric constructions (D03D). Teijin ranks second with 6 patent records, centered on chemical filament features and yarn texturing.
The field is classified as Decline. Annual filings peaked in 2019 and have eased back sharply since then, with no sustained recovery visible through 2024. Teams should treat this as a post-first-wave environment rather than an actively growing frontier.
The United States is the leading jurisdiction by patent records, followed by Japan and then China. Europe (EPO) and WIPO (PCT) filings are present at lower levels. Canada, India, South Korea, and several other offices each have a small number of records.
H01B (cables, conductors, and insulators) is the largest branch, reflecting the cable-shielding and wire-harness orientation of the leading applicant. D01F (chemical filament and fibre features) and D06M (textile chemical treatment) are the next most represented, followed by D02G (yarn texturing) and D03D (woven fabrics).
The evidence identifies two co-filing pairs: Asahi Chemical Industry with Asahi Kasei (2 shared records), and Michael Piotrowski with Federal Mogul Powertrain (2 shared records). The collaboration ecosystem is thin, and no large multi-party research consortium has been identified in this specific technology area.
