What this shows Cockerill's Innovation Score is 42.5/100 (top 30% 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 Cockerill?

Each dot is one of Cockerill’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). Cockerill’s own 10.9 claims/patent is at or below the 13.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cockerill's grants concentrate

Cockerill Maintenance & Ingenierie S.A. is a focused PatentsView assignee: 39 CPC subclasses with 34.8% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2015. By volume, Cockerill sits between China Three Gorges Corporation and Creighton University.

Cockerill's three-year grant acceleration

Cockerill Maintenance & Ingenierie S.A. shows 4 grants in 2022–2024 against only 9 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.
