What this shows Des-case's Innovation Score is 30.0/100 (33rd 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 Des-case?

Each dot is one of Des-case’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). Des-case’s own 10.8 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Des-case's grants concentrate

Des-Case Corporation is a focused PatentsView assignee: 8 CPC subclasses with 50% of grants classified under B01D (Separation). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2015. By volume, Des-case sits between Dyco, Inc. and Discovery Limited.

Des-case's three-year grant acceleration

Des-Case Corporation shows 4 grants in 2022–2024 against only 9 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.
