Portfolio overview

ES FiberVisions Co., Ltd. has been granted 20 US utility patents between 2016 and 2023, placing ES FiberVisions Co., Ltd. at rank #14,585 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.7 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, ES FiberVisions Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 32.2/100 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 6 grants, compared with 14 in the 2015–2019 window — a -57% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. ES FiberVisions Co., Ltd.'s 6.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ES FiberVisions Co., Ltd. against peers pursuing similar technology classes.
