What this shows Jiangsu's Innovation Score is 37.5/100 (top 43% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Jiangsu?

Each dot is one of Jiangsu’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Jiangsu’s own 12.2 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Jiangsu's grants concentrate

Jiangsu Hengli Chemical Fibre Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 100% of grants classified under D01F (Chemical Features IN THE Manufacture OF Artificial Filaments, Threads, Fibres, Bristles OR RIBBONS; Apparatus Specially Adapted FOR THE Manufacture OF Carbon Filaments). Peak complete grant year is 2021 (11 grants) versus a trough of 1 in 2018. By volume, Jiangsu sits between Intarcia Therapeutics, Inc. and Joyson Safety Systems Germany GmbH.

Jiangsu's three-year grant acceleration

Jiangsu Hengli Chemical Fibre Co., Ltd. shows 9 grants in 2022–2024 against only 19 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
