What this shows CHU's Innovation Score is 39.0/100 (top 39% 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 10.2 claims/patent is ABOVE the 8.9 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 Nantes is a focused PatentsView assignee: 18 CPC subclasses with 66.7% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2015. By volume, CHU sits between Checkers Industrial Products, LLC and Cnbm Research Institute FOR Advanced Glass Materials Group Co., Ltd..

CHU's three-year grant acceleration

CHU Nantes shows 5 grants in 2022–2024 against only 4 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.
