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 1.5 claims/patent is at or below the 9.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhangjiagang's grants concentrate

Zhangjiagang SMK MFG. Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 10% of grants classified under Y10T (Technical Subjects Covered BY Former US Classification). Peak complete grant year is 2021 (6 grants) versus a trough of 1 in 2024. By volume, Zhangjiagang sits between Zedsen Limited and Zimperium, Inc..

Zhangjiagang's three-year grant acceleration

Zhangjiagang SMK MFG. Co., Ltd. shows 1 grants in 2022–2024 against only 8 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.
