What this shows Douglas's Innovation Score is 30.3/100 (34th percentile 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 Douglas?

Each dot is one of Douglas’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). Douglas’s own 13.4 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Douglas's grants concentrate

Douglas Scientific, LLC is a focused PatentsView assignee: 11 CPC subclasses with 83.3% of grants classified under B01L (Chemical OR Physical Laboratory Apparatus FOR General USE). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2016. By volume, Douglas sits between DK City Corporation and DTN, LLC.

Douglas's three-year grant acceleration

Douglas Scientific, LLC shows 2 grants in 2022–2024 against only 8 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.
