What this shows Centre's Innovation Score is 37.7/100 (top 43% 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 14.8 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Centre's grants concentrate

Centre Technique DE L'industrie DES Papiers, Cartons ET Celluloses is a focused PatentsView assignee: 17 CPC subclasses with 50% of grants classified under D21C (Production OF Cellulose BY Removing Non-cellulose Substances From Cellulose-containing MATERIALS; Regeneration OF Pulping LIQUORS; Apparatus Therefor). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2018. By volume, Centre sits between Cellectar Biosciences, Inc. and Ceske Vysoke Uceni Technicke V Praze.

Centre's three-year grant acceleration

Centre Technique DE L'industrie DES Papiers, Cartons ET Celluloses shows 2 grants in 2022–2024 against only 2 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.
