What this shows Guizhou's Innovation Score is 43.2/100 (top 29% 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 Guizhou?

Each dot is one of Guizhou’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). Guizhou’s own 7.0 claims/patent is ABOVE the 1.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Guizhou's grants concentrate

Guizhou Power Grid Company Limited is a focused PatentsView assignee: 12 CPC subclasses with 50% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). By volume, Guizhou sits between Guangzhou Qiji Technology Co., Ltd. and H Quest Partners, LP.

Guizhou's three-year grant acceleration

Guizhou Power Grid Company Limited shows 4 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.
