What this shows DUS's Innovation Score is 44.0/100 (top 27% 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 DUS?

Each dot is one of DUS’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). DUS’s own 15.6 claims/patent is ABOVE the 8.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where DUS's grants concentrate

DUS Operating Inc. is a focused PatentsView assignee: 31 CPC subclasses with 30% of grants classified under F16H (Gearing). Peak complete grant year is 2021 (12 grants) versus a trough of 1 in 2023. By volume, DUS sits between Dipsol Chemicals Co., Ltd. and Danstar Ferment AG.

DUS's three-year grant acceleration

DUS Operating Inc. shows 8 grants in 2022–2024 against only 12 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.
