What this shows Ringspann's Innovation Score is 39.3/100 (top 39% 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 Ringspann?

Each dot is one of Ringspann’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). Ringspann’s own 13.8 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ringspann's grants concentrate

Ringspann GmbH is a focused PatentsView assignee: 7 CPC subclasses with 70% of grants classified under F16D (Couplings FOR Transmitting ROTATION; CLUTCHES; Brakes). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2015. By volume, Ringspann sits between Revol Porcelaine S.A. and Roccat GMBH.

Ringspann's three-year grant acceleration

Ringspann GmbH shows 4 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.
