What this shows Zhongshan's Innovation Score is 40.8/100 (top 35% 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 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 3.4 claims/patent is at or below the 16.5 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 Bolang Electronic Technology Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 21.4% of grants classified under F21W (Indexing Scheme Associated With Subclasses F21k, F21l, F21s and F21v, Relating TO Uses OR Applications OF Lighting Devices OR Systems). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2021. By volume, Zhongshan sits between Yukka Magic LLC and Zahoransky AG.

Zhongshan's three-year grant acceleration

Zhongshan Bolang Electronic Technology Co., Ltd. shows 10 grants in 2022–2024 against only 1 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.
