What this shows Digital's Innovation Score is 37.3/100 (top 44% 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 Digital?

Each dot is one of Digital’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). Digital’s own 19.9 claims/patent is ABOVE the 12.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Digital's grants concentrate

Digital Lumens Incorporated is a focused PatentsView assignee: 13 CPC subclasses with 84.2% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2017. By volume, Digital sits between Daikin America, Inc. and Daimay North America Autmotive, Inc..

Digital's three-year grant acceleration

Digital Lumens Incorporated shows 2 grants in 2022–2024 against only 6 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.
