Where DE's grants concentrate

DE Nora Permelec Ltd is a focused PatentsView assignee: 19 CPC subclasses with 97% of grants classified under C25B (Electrolytic OR Electrophoretic Processes FOR THE Production OF Compounds OR NON-METALS; Apparatus Therefor). Peak complete grant year is 2020 (8 grants) versus a trough of 1 in 2016. By volume, DE sits between CrowdComfort, Inc. and Drum Workshop, Inc..

DE's three-year grant acceleration

DE Nora Permelec Ltd shows 11 grants in 2022–2024 against only 14 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.
