What this shows Elkem's Innovation Score is 49.9/100 (top 14% 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 Elkem?

Each dot is one of Elkem’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). Elkem’s own 17.9 claims/patent is ABOVE the 14.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Elkem's grants concentrate

Elkem Silicones France SAS is a focused PatentsView assignee: 35 CPC subclasses with 76.3% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2020 (7 grants) versus a trough of 1 in 2018. By volume, Elkem sits between DunAn Microstaq, Inc. and Express Scripts, Inc..

Elkem's three-year grant acceleration

Elkem Silicones France SAS shows 16 grants in 2022–2024 against only 19 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.
