Where Eaglepicher's grants concentrate

Eaglepicher Technologies, LLC is a focused PatentsView assignee: 20 CPC subclasses with 85.2% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2016 (6 grants) versus a trough of 1 in 2021. By volume, Eaglepicher sits between Ecotech, LLC and First Principles, Inc..

Eaglepicher's three-year grant acceleration

Eaglepicher Technologies, LLC shows 3 grants in 2022–2024 against only 6 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.
