Does more volume mean deeper claims for Cleana?

Each dot is one of Cleana’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). Cleana’s own 23.3 claims/patent is ABOVE the 8.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cleana's grants concentrate

Cleana Inc. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under A47K (Sanitary Equipment NOT Otherwise Provided FOR ; Toilet Accessories). By volume, Cleana sits between Civil Aviation Flight University of China and ClearOne Communications Hong Kong Ltd..

Cleana's three-year grant acceleration

Cleana Inc. shows 3 grants in 2022–2024 against only 0 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.
