What this shows Constellium's Innovation Score is 46.3/100 (top 21% 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.

Where Constellium's grants concentrate

Constellium Issoire is a focused PatentsView assignee: 28 CPC subclasses with 73.3% of grants classified under C22C (Alloys). Peak complete grant year is 2020 (9 grants) versus a trough of 2 in 2021. By volume, Constellium sits between California Expanded Metal Products Company and Danfoss Commercial Compressors.

Constellium's three-year grant acceleration

Constellium Issoire shows 13 grants in 2022–2024 against only 17 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.
