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 12.8 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 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.
