How Centre’s 40.5 Innovation Score adds up

The same four weighted components behind every Innovation Score on PlainPatent: portfolio volume, grant velocity, technology breadth, and claim depth.

Volume 6.2 pts (15%) Velocity 13.3 pts (33%) Breadth 12.2 pts (30%) Claim depth 8.8 pts (22%)

What this shows Centre's Innovation Score is 40.5/100 (top 35% 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 Centre?

Each dot is one of Centre’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). Centre’s own 14.6 claims/patent is ABOVE the 8.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Centre's grants concentrate

Centre DE Recherches MÉTALLURGIQUES ASBL—CENTRUM Voor Research IN DE Metallurgie VZW is a focused PatentsView assignee: 12 CPC subclasses with 20% of grants classified under C21C (Processing OF Pig-iron, e.g. Refining, Manufacture OF Wrought-iron OR STEEL; Treatment IN Molten State OF Ferrous Alloys). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2015. By volume, Centre sits between Censhare GMBH and Centro Sviluppo Materiali S.P.A..

Centre's three-year grant acceleration

Centre DE Recherches MÉTALLURGIQUES ASBL—CENTRUM Voor Research IN DE Metallurgie VZW shows 2 grants in 2022–2024 against only 1 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.
