Where Ecole's grants concentrate

Ecole Normale Superieure is a focused PatentsView assignee: 34 CPC subclasses with 34.5% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2015. By volume, Ecole sits between Delta Design, Inc. and Etablissement Francais DU Sang (EFS).

Ecole's three-year grant acceleration

Ecole Normale Superieure shows 6 grants in 2022–2024 against only 11 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.
