Where Celanese's grants concentrate

Celanese EVA Performance Polymers LLC is a focused PatentsView assignee: 11 CPC subclasses with 55.6% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2022. By volume, Celanese sits between Catalytic Distillation Technologies and Cellino Biotech, Inc..

Celanese's three-year grant acceleration

Celanese EVA Performance Polymers LLC shows 5 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.
