Portfolio overview
NANTONG TEXTILE & SILK INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE has been granted 14 US utility patents between 2018 and 2025, placing NANTONG TEXTILE & SILK INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE at rank #20,120 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.4 claims per patent with primary concentration in D06B (TREATING TEXTILE MATERIALS USING LIQUIDS, GASES OR VAPOURS). As a Foreign Government, NANTONG TEXTILE & SILK INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.4/100 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 8 grants, compared with 6 in the 2015–2019 window — a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign Government 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. NANTONG TEXTILE & SILK INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE's 6.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark NANTONG TEXTILE & SILK INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE against peers pursuing similar technology classes.
