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 11.8 claims/patent is at or below the 12.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Guangdong's grants concentrate

Guangdong Meizhi Precision-manufacturing Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2021. By volume, Guangdong sits between Guangdong Jiamei Ceramics Co., Ltd. and Guangdong Zhongsheng Pharmaceutical Co., Ltd.

Guangdong's three-year grant acceleration

Guangdong Meizhi Precision-manufacturing Co., Ltd. shows 3 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.
