What this shows CHU's Innovation Score is 32.4/100 (41st 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 CHU?

Each dot is one of CHU’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). CHU’s own 18.7 claims/patent is ABOVE the 8.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where CHU's grants concentrate

CHU Sainte-justine is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2015. By volume, CHU sits between China Railway Tunnel Group Co., Ltd. and Cirel Systems Private Limited.

CHU's three-year grant acceleration

CHU Sainte-justine shows 1 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.
