What this shows Dietze's Innovation Score is 30.1/100 (33rd 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 Dietze?

Each dot is one of Dietze’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). Dietze’s own 13.5 claims/patent is ABOVE the 11.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dietze's grants concentrate

Dietze & Schell Maschinenfabrik GmbH & Co. KG is a focused PatentsView assignee: 6 CPC subclasses with 83.3% of grants classified under B65H (Handling Thin OR Filamentary Material, e.g. Sheets, Webs, Cables). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2024. By volume, Dietze sits between DiaMed GmbH and Digital Solid State Propulsion LLC.

Dietze's three-year grant acceleration

Dietze & Schell Maschinenfabrik GmbH & Co. KG shows 1 grants in 2022–2024 against only 0 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.
