Where Cleansorb's grants concentrate

Cleansorb Limited is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2018. By volume, Cleansorb sits between Clean Energy Technology Association, Inc. and Clearmind Medicine Inc..

Cleansorb's three-year grant acceleration

Cleansorb Limited shows 2 grants in 2022–2024 against only 2 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.
