What this shows State's Innovation Score is 44.3/100 (top 26% 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 12.7 claims/patent is at or below the 14.7 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 Anhui Electric Power Research Institute is a focused PatentsView assignee: 8 CPC subclasses with 33.3% of grants classified under A62C (Fire-fighting). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, State sits between Star Systems International Limited and Steer Engineering Private Limited.

State's three-year grant acceleration

State Grid Anhui Electric Power Research Institute shows 3 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.
