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 22.1 claims/patent is ABOVE the 16.2 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 Pharmaceuticals Limited is a focused PatentsView assignee: 3 CPC subclasses with 92.9% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2016. By volume, Douglas sits between DG Holdings, Inc. and Duquesne University OF THE Holy Ghost.
Douglas's three-year grant acceleration
Douglas Pharmaceuticals Limited shows 6 grants in 2022–2024 against only 4 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.
