What this shows State's Innovation Score is 48.2/100 (top 17% 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 8.6 claims/patent is at or below the 12.5 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 Huzhou Power Supply Company is a focused PatentsView assignee: 19 CPC subclasses with 50% of grants classified under H02G (Installation OF Electric Cables OR Lines, OR OF Combined Optical AND Electric Cables OR Lines). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2015. By volume, State sits between ST-Ericsson (France) SAS and Sterilumen, Inc..

State's three-year grant acceleration

State Grid Huzhou Power Supply Company shows 5 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.
