What this shows State's Innovation Score is 39.6/100 (top 38% 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 8.7 claims/patent is at or below the 11.1 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 Chongqing Electric Power Co. Electric Power Research Institute is a focused PatentsView assignee: 20 CPC subclasses with 27.3% of grants classified under Y02T (Climate Change Mitigation Technologies Related TO Transportation). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, State sits between Standard Energy Inc. and Strata Innovations Pty Limited.

State's three-year grant acceleration

State Grid Chongqing Electric Power Co. Electric Power Research Institute shows 3 grants in 2022–2024 against only 2 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.
