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 16.1 claims/patent is at or below the 17.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Elkem's grants concentrate
Elkem ASA is a focused PatentsView assignee: 28 CPC subclasses with 55% 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 (6 grants) versus a trough of 2 in 2019. By volume, Elkem sits between Duality Technologies, Inc. and Escape Fitness Limited.
Elkem's three-year grant acceleration
Elkem ASA shows 12 grants in 2022–2024 against only 7 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.
