Does more volume mean deeper claims for Zhuhai?

Each dot is one of Zhuhai’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). Zhuhai’s own 4.4 claims/patent is at or below the 10.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Zhuhai's grants concentrate

Zhuhai Quin Technology Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 28.6% of grants classified under A61J (Containers Specially Adapted FOR Medical OR Pharmaceutical PURPOSES; Devices OR Methods Specially Adapted FOR Bringing Pharmaceutical Products Into Particular Physical OR Administering FORMS; Devices ). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2023. By volume, Zhuhai sits between Zhejiang Yuejia Pharmaceuticals Co., Ltd and Ziip, Inc..

Zhuhai's three-year grant acceleration

Zhuhai Quin Technology Co., Ltd. shows 3 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.
