What this shows Erowa's Innovation Score is 36.2/100 (top 47% 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 Erowa?

Each dot is one of Erowa’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). Erowa’s own 17.3 claims/patent is ABOVE the 14.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Erowa's grants concentrate

Erowa AG is a focused PatentsView assignee: 9 CPC subclasses with 81.8% of grants classified under B23Q (Details, Components, OR Accessories FOR Machine Tools, e.g. Arrangements FOR Copying OR Controlling ; Machine Tools IN General Characterised BY THE Construction OF Particular Details OR COMPONENTS; Co). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Erowa sits between Enfabrica Corporation and Estetra Sprl.

Erowa's three-year grant acceleration

Erowa AG shows 2 grants in 2022–2024 against only 2 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.
