What this shows Centre's Innovation Score is 22.0/100 (9th 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.

Does more volume mean deeper claims for Centre?

Each dot is one of Centre’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). Centre’s own 8.2 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Centre's grants concentrate

Centre Hospitalier Universitaire Saint-etienne is a focused PatentsView assignee: 6 CPC subclasses with 40% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2017. By volume, Centre sits between Central BAG & Burlap Co. and Cesca Therapeutics, Inc..

Centre's three-year grant acceleration

Centre Hospitalier Universitaire Saint-etienne shows 1 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.
