What this shows Schunk's Innovation Score is 46.2/100 (top 21% 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 Schunk?

Each dot is one of Schunk’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). Schunk’s own 11.2 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Schunk's grants concentrate

Schunk Sonosystems GMBH is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under B23K (Soldering OR UNSOLDERING; WELDING; Cladding OR Plating BY Soldering OR WELDING; Cutting BY Applying Heat Locally, e.g. Flame CUTTING; Working BY Laser Beam). Peak complete grant year is 2022 (8 grants) versus a trough of 1 in 2021. By volume, Schunk sits between S.P.M. Instrument AB and Shunsin Technology (ZHONG SHAN) Limited.

Schunk's three-year grant acceleration

Schunk Sonosystems GMBH shows 14 grants in 2022–2024 against only 5 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.
