What this shows Clean's Innovation Score is 29.7/100 (32nd 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 Clean?

Each dot is one of Clean’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). Clean’s own 17.8 claims/patent is ABOVE the 9.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Clean's grants concentrate

Clean Slurry Technology Inc. is a focused PatentsView assignee: 10 CPC subclasses with 60% of grants classified under B07B (Separating Solids From Solids BY Sieving, Screening, Sifting OR BY Using GAS CURRENTS; Separating BY Other DRY Methods Applicable TO Bulk Material, e.g. Loose Articles FIT TO BE Handled Like Bulk Mate). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2019. By volume, Clean sits between Cleafy SOCIETÀ PER Azioni and Clearist Inc..

Clean's three-year grant acceleration

Clean Slurry Technology Inc. shows 1 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.
