What this shows Walter's Innovation Score is 31.9/100 (39th percentile 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 Walter?

Each dot is one of Walter’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). Walter’s own 15.3 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 Walter's grants concentrate

Walter Maschinenbau GMBH is a focused PatentsView assignee: 13 CPC subclasses with 70% 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 (3 grants) versus a trough of 1 in 2020. By volume, Walter sits between Voxel Rad, Ltd. and WEB Spark Ltd..

Walter's three-year grant acceleration

Walter Maschinenbau GMBH shows 1 grants in 2022–2024 against only 4 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.
