What this shows Ardex's Innovation Score is 52.6/100 (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 Ardex?

Each dot is one of Ardex’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). Ardex’s own 17.6 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ardex's grants concentrate

Ardex Group GmbH is a focused PatentsView assignee: 20 CPC subclasses with 40% of grants classified under F23G (Cremation FURNACES; Consuming Waste Products BY Combustion). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2021. By volume, Ardex sits between Arcelormittal Tubular Products Luxembourg S.A. and Arkh, Inc..

Ardex's three-year grant acceleration

Ardex Group GmbH shows 3 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.
