Where Fiberlean's grants concentrate

Fiberlean Technologies Limited is a focused PatentsView assignee: 25 CPC subclasses with 86.8% of grants classified under D21H (Pulp COMPOSITIONS; Preparation Thereof NOT Covered BY Subclasses D21c OR D21D; Impregnating OR Coating OF PAPER; Treatment OF Finished Paper NOT Covered BY Class B31 OR Subclass D21G; Paper NOT Otherw). Peak complete grant year is 2020 (7 grants) versus a trough of 2 in 2024. By volume, Fiberlean sits between Endocyte, Inc. and Foundation Medicine, Inc..

Fiberlean's three-year grant acceleration

Fiberlean Technologies Limited shows 13 grants in 2022–2024 against only 19 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.
