Where Domtar's grants concentrate

Domtar Paper Company, LLC is a focused PatentsView assignee: 20 CPC subclasses with 88.9% 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 2022 (4 grants) versus a trough of 1 in 2016. By volume, Domtar sits between Diageo North America, Inc. and Dr. Falk Pharma Gmbh.

Domtar's three-year grant acceleration

Domtar Paper Company, LLC shows 8 grants in 2022–2024 against only 4 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.
