Where Billerudkorsnas's grants concentrate

Billerudkorsnas AB is a focused PatentsView assignee: 17 CPC subclasses with 88.2% 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 2019 (3 grants) versus a trough of 2 in 2018. By volume, Billerudkorsnas sits between Bien-air Holding SA and Bnsf Logistics, LLC.

Billerudkorsnas's three-year grant acceleration

Billerudkorsnas AB shows 8 grants in 2022–2024 against only 5 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.
