What this shows DS's Innovation Score is 26.5/100 (20th 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 DS?

Each dot is one of DS’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). DS’s own 12.1 claims/patent is ABOVE the 7.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where DS's grants concentrate

DS Biopharma Limited is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2019. By volume, DS sits between Dongguan Suntech Electronics Co., Ltd. and Dansons US, LLC.

DS's three-year grant acceleration

DS Biopharma Limited 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.
