Does more volume mean deeper claims for Zhongshan?
Each dot is one of Zhongshan’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). Zhongshan’s own 1.0 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Zhongshan's grants concentrate
Zhongshan Xiaolan Town Yaoshuoli Lighting Factory is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Zhongshan sits between Zhejiang Research Institute OF Chemical Industry Co., Ltd. and Zinc8 Energy Solutions Inc..
Zhongshan's three-year grant acceleration
Zhongshan Xiaolan Town Yaoshuoli Lighting Factory shows 4 grants in 2022–2024 against only 2 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.
