What this shows Nantong's Innovation Score is 38.4/100 (top 41% 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 Nantong?

Each dot is one of Nantong’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). Nantong’s own 6.4 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nantong's grants concentrate

Nantong Textile & Silk Industrial Technology Research Institute is a focused PatentsView assignee: 31 CPC subclasses with 35.7% of grants classified under D06B (Treating Textile Materials Using Liquids, Gases OR Vapours). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2020. By volume, Nantong sits between Nanobacterie and Ncan Genomics, Inc..

Nantong's three-year grant acceleration

Nantong Textile & Silk Industrial Technology Research Institute shows 5 grants in 2022–2024 against only 6 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.
