What this shows State's Innovation Score is 57.5/100 (top 5% 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 9.8 claims/patent is at or below the 17.0 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 Research Institute is a focused PatentsView assignee: 34 CPC subclasses with 39.1% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2016. By volume, State sits between Sixring Inc. and Safety Syringes, Inc..

State's three-year grant acceleration

State Grid Jiangsu Electric Power Research Institute shows 11 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.
