What this shows Douglas's Innovation Score is 40.9/100 (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 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 25.1 claims/patent is ABOVE the 13.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Douglas's grants concentrate

Douglas Machine Inc. is a focused PatentsView assignee: 11 CPC subclasses with 68.2% of grants classified under B65B (Machines, Apparatus OR Devices FOR, OR Methods OF, Packaging Articles OR MATERIALS; Unpacking). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2018. By volume, Douglas sits between Deutsches Elektronen-Synchrotron Desy and Elkamet Kunststofftechnik GMBH.

Douglas's three-year grant acceleration

Douglas Machine Inc. shows 4 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.
