What this shows State's Innovation Score is 41.2/100 (top 34% 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 7.5 claims/patent is at or below the 14.5 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 Electric Power Rerearch Institute Co. Ltd is a focused PatentsView assignee: 8 CPC subclasses with 66.7% 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 2024 (4 grants) versus a trough of 2 in 2016. By volume, State sits between Starbreeze Paris and Stefan Pfaff Werkzeug- UND Formenbau GMBH & Co KG.

State's three-year grant acceleration

State Grid Electric Power Rerearch Institute Co. Ltd shows 4 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.
