What this shows Guangdong's Innovation Score is 27.3/100 (23rd percentile 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 Guangdong?

Each dot is one of Guangdong’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). Guangdong’s own 17.8 claims/patent is ABOVE the 9.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guangdong's grants concentrate

Guangdong Zhongsheng Pharmaceutical Co., Ltd is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2019. By volume, Guangdong sits between Guangdong Meizhi Precision-manufacturing Co., Ltd. and Guangzhou Fullriver Battery NEW Technology Co., Ltd..

Guangdong's three-year grant acceleration

Guangdong Zhongsheng Pharmaceutical Co., Ltd shows 1 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.
