What this shows C-tec's Innovation Score is 46.8/100 (top 20% 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 C-tec?

Each dot is one of C-tec’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). C-tec’s own 17.1 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where C-tec's grants concentrate

C-tec Constellium Technology Center is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under C22F (Changing THE Physical Structure OF Non-ferrous Metals AND Non-ferrous Alloys). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2023. By volume, C-tec sits between BÖWE Systec GmbH and C2 Therapeutics, Inc..

C-tec's three-year grant acceleration

C-tec Constellium Technology Center shows 3 grants in 2022–2024 against only 0 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.
