Portfolio overview

Jiangsu Hengli Chemical Fibre Co., Ltd. has been granted 31 US utility patents between 2018 and 2025, placing Jiangsu Hengli Chemical Fibre Co., Ltd. at rank #10,070 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 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, Jiangsu Hengli Chemical Fibre Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Jiangsu sits between Intarcia Therapeutics, Inc. (31 patents, rank #10,066) and Joyson Safety Systems Germany Gmbh (31 patents, rank #10,074) - the closest US assignees by grant volume. The composite Innovation Score of 37.5/100 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 27 grants, compared with 4 in the 2015–2019 window, a +575% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Jiangsu Hengli Chemical Fibre Co., Ltd.'s 12.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Jiangsu Hengli Chemical Fibre Co., Ltd. against peers pursuing similar technology classes.
