What this shows Clean's Innovation Score is 37.6/100 (top 43% 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.

Where Clean's grants concentrate

Clean Chemistry, Inc. is a focused PatentsView assignee: 16 CPC subclasses with 70% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2017. By volume, Clean sits between Centre Hospitalier Regional Et Universitaire De Brest and Consumer 2.0 Inc..

Clean's three-year grant acceleration

Clean Chemistry, Inc. shows 4 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.
