Where Epalex's grants concentrate

Epalex Corporation is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2021. By volume, Epalex sits between Environmental Dynamics International, Inc. and ESS 2 Tech, LLC.

Epalex's three-year grant acceleration

Epalex Corporation shows 4 grants in 2022–2024 against only 1 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.
