What this shows Guangdong's Innovation Score is 34.1/100 (46th 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 4.8 claims/patent is at or below the 10.0 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 Galanz Microwave Electrical Appliances Manufacturing Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 40% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). By volume, Guangdong sits between GS Development AB and Guangdong K-silver Industrial Co., Ltd..
Guangdong's three-year grant acceleration
Guangdong Galanz Microwave Electrical Appliances Manufacturing Co., Ltd. shows 3 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.
