What this shows RUD's Innovation Score is 35.5/100 (top 49% 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 RUD?

Each dot is one of RUD’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). RUD’s own 14.4 claims/patent is ABOVE the 13.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where RUD's grants concentrate

RUD Ketten Rieger & Dietz GMBH U. Co. KG is a focused PatentsView assignee: 12 CPC subclasses with 45.5% of grants classified under B66C (CRANES; Load-engaging Elements OR Devices FOR Cranes, Capstans, Winches, OR Tackles). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2017. By volume, RUD sits between RIC Investments LLC and ResearchGate GmbH.

RUD's three-year grant acceleration

RUD Ketten Rieger & Dietz GMBH U. Co. KG shows 4 grants in 2022–2024 against only 7 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.
