What this shows Witzenmann's Innovation Score is 28.8/100 (29th 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 Witzenmann?

Each dot is one of Witzenmann’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). Witzenmann’s own 13.1 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Witzenmann's grants concentrate

Witzenmann GmbH is a focused PatentsView assignee: 7 CPC subclasses with 80% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2020. By volume, Witzenmann sits between Wetend Technologies Oy and Wostec, Inc..

Witzenmann's three-year grant acceleration

Witzenmann GmbH shows 1 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.
