What this shows Element's Innovation Score is 52.4/100 (top 10% 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 Element?

Each dot is one of Element’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). Element’s own 13.3 claims/patent is at or below the 17.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Element's grants concentrate

Element Six Limited is a focused PatentsView assignee: 48 CPC subclasses with 34.7% of grants classified under C22C (Alloys). Peak complete grant year is 2017 (22 grants) versus a trough of 1 in 2024. By volume, Element sits between Cortica Ltd. and Hyosung Heavy Industries Corporation.

Element's three-year grant acceleration

Element Six Limited shows 10 grants in 2022–2024 against only 16 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.
