What this shows Duke's Innovation Score is 52.6/100 (top 10% 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 Duke?

Each dot is one of Duke’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). Duke’s own 17.1 claims/patent is ABOVE the 13.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Duke's grants concentrate

Duke Energy Corporation is a focused PatentsView assignee: 36 CPC subclasses with 36.1% of grants classified under Y04S (Systems Integrating Technologies Related TO Power Network Operation, Communication OR Information Technologies FOR Improving THE Electrical Power Generation, Transmission, Distribution, Management OR ). Peak complete grant year is 2023 (9 grants) versus a trough of 2 in 2016. By volume, Duke sits between D & D Group PTY Ltd and DrFirst.com, Inc..

Duke's three-year grant acceleration

Duke Energy Corporation shows 13 grants in 2022–2024 against only 10 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.
