What this shows Guangdong's Innovation Score is 40.4/100 (top 36% 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 12.5 claims/patent is ABOVE the 11.7 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 Midea Environmental Technologies Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under F04C (Rotary-piston, OR Oscillating-piston, Positive-displacement Machines FOR Liquids ; Rotary-piston, OR Oscillating-piston, Positive-displacement Pumps). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2022. By volume, Guangdong sits between Guandong Vking Intelligent Technology Co., Ltd. and Guangdong SKG Intelligent Technology Co., Ltd.

Guangdong's three-year grant acceleration

Guangdong Midea Environmental Technologies Co., Ltd. shows 5 grants in 2022–2024 against only 0 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.
