What this shows State's Innovation Score is 31.5/100 (38th 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 State?

Each dot is one of State’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). State’s own 10.7 claims/patent is ABOVE the 5.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where State's grants concentrate

State Grid Zhejiang Electric Power Co., Ltd is a focused PatentsView assignee: 10 CPC subclasses with 42.9% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). By volume, State sits between ST&T International, Inc. and Stella Mccartney Limited.

State's three-year grant acceleration

State Grid Zhejiang Electric Power Co., Ltd shows 3 grants in 2022–2024 against only 3 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.
