What this shows Guangdong's Innovation Score is 40.6/100 (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 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 12.7 claims/patent is at or below the 15.2 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 Compressor Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 45.2% of grants classified under F25B (Refrigeration Machines, Plants OR SYSTEMS; Combined Heating AND Refrigeration SYSTEMS; Heat Pump Systems). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2017. By volume, Guangdong sits between Geneial LLC and GungHo Online Entertainment, Inc..

Guangdong's three-year grant acceleration

Guangdong Meizhi Compressor Co., Ltd. shows 14 grants in 2022–2024 against only 12 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.
