Does more volume mean deeper claims for Chengdu?

Each dot is one of Chengdu’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). Chengdu’s own 1.0 claims/patent is at or below the 12.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Chengdu's grants concentrate

Chengdu Yishouweisheng Technology Inc. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2019. By volume, Chengdu sits between ChemFree Corporation and Children's Medical Research Institute.

Chengdu's three-year grant acceleration

Chengdu Yishouweisheng Technology Inc. shows 3 grants in 2022–2024 against only 3 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.
