What this shows Ecole's Innovation Score is 30.1/100 (33rd percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where Ecole's grants concentrate

Ecole Nationale Superieure de Chimie is a focused PatentsView assignee: 12 CPC subclasses with 42.9% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2017. By volume, Ecole sits between EasyNotes Ltd. and Eisai Inc..

Ecole's three-year grant acceleration

Ecole Nationale Superieure de Chimie shows 2 grants in 2022–2024 against only 3 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.
