What this shows State's Innovation Score is 55.9/100 (top 6% 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 12.1 claims/patent is at or below the 14.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where State's grants concentrate

State Grid Jiangsu Electric Power Co. Ltd. is a focused PatentsView assignee: 44 CPC subclasses with 35.7% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2023 (10 grants) versus a trough of 1 in 2017. By volume, State sits between Shenzhen Relx Technology Co., Ltd. and Shenzhen Mindray Scientific Co., Ltd..

State's three-year grant acceleration

State Grid Jiangsu Electric Power Co. Ltd. shows 22 grants in 2022–2024 against only 12 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.
