Where Eocell's grants concentrate

EoCell Limited is a focused PatentsView assignee: 11 CPC subclasses with 100% 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 2019 (3 grants) versus a trough of 1 in 2024. By volume, Eocell sits between Enevo Oy and Estis Compression, LLC.

Eocell's three-year grant acceleration

EoCell Limited shows 1 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.
