What this shows Ecole's Innovation Score is 50.2/100 (top 13% 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.

Does more volume mean deeper claims for Ecole?

Each dot is one of Ecole’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Ecole’s own 14.3 claims/patent is at or below the 19.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ecole's grants concentrate

Ecole Centrale DE Lyon is a focused PatentsView assignee: 45 CPC subclasses with 24% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2015. By volume, Ecole sits between Deep Isolation, Inc. and Ener-Core Power, Inc..

Ecole's three-year grant acceleration

Ecole Centrale DE Lyon shows 7 grants in 2022–2024 against only 7 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.
