What this shows Zhangjiagang's Innovation Score is 33.5/100 (45th percentile 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 Zhangjiagang?

Each dot is one of Zhangjiagang’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). Zhangjiagang’s own 13.3 claims/patent is ABOVE the 8.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zhangjiagang's grants concentrate

Zhangjiagang Kangde XIN Optronics Material Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 83.3% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2017. By volume, Zhangjiagang sits between Yum Connect, LLC and Zilltek Technology Corp..

Zhangjiagang's three-year grant acceleration

Zhangjiagang Kangde XIN Optronics Material Co., Ltd. shows 4 grants in 2022–2024 against only 4 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.
