Portfolio overview

Taiwan Textile Research Institute has been granted 62 US utility patents between 2015 and 2025, placing Taiwan Textile Research Institute at rank #5,552 across all assignees tracked by PlainPatent. This portfolio spans 53 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in D01F (CHEMICAL FEATURES IN THE MANUFACTURE OF ARTIFICIAL FILAMENTS, THREADS, FIBRES, BRISTLES OR RIBBONS; APPARATUS SPECIALLY ADAPTED FOR THE MANUFACTURE OF CARBON FILAMENTS). As a Foreign Corporation, Taiwan Textile Research Institute is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Taiwan sits between Societe D'exploitation DE Produits POUR LES Industries Chimiques Seppic (62 patents, rank #5,548) and The Babcock & Wilcox Company (62 patents, rank #5,556) - the closest US assignees by grant volume. The composite Innovation Score of 61.7/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 37 grants, compared with 25 in the 2015–2019 window, a +48% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Taiwan Textile Research Institute's 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 53 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Taiwan Textile Research Institute against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
