What this shows Guangdong's Innovation Score is 29.0/100 (29th 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 10.1 claims/patent is ABOVE the 7.5 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 Institute of Eco-Environmental Science & Technology is a focused PatentsView assignee: 15 CPC subclasses with 50% of grants classified under B09C (Reclamation OF Contaminated Soil). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2017. By volume, Guangdong sits between GreenTec-USA, Inc. and Guangzhou Yu Junrui Trading Co., Ltd.

Guangdong's three-year grant acceleration

Guangdong Institute of Eco-Environmental Science & Technology shows 1 grants in 2022–2024 against only 4 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.
