What this shows Guangdong's Innovation Score is 51.3/100 (top 12% 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 8.3 claims/patent is at or below the 13.7 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 University OF Petrochemical Technology is a focused PatentsView assignee: 23 CPC subclasses with 35.7% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2021. By volume, Guangdong sits between GP Enterprises Co. Ltd and Garrity Power Services LLC.

Guangdong's three-year grant acceleration

Guangdong University OF Petrochemical Technology shows 10 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.
