What this shows Schunk's Innovation Score is 37.4/100 (top 44% 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 12.5 claims/patent is at or below the 16.5 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 GmbH &Co. KG Spann-und Greiftechnik is a focused PatentsView assignee: 14 CPC subclasses with 76.5% of grants classified under B25J (MANIPULATORS; Chambers Provided With Manipulation Devices). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2017. By volume, Schunk sits between Saint-gobain Adfors Canada, Ltd. and Seeing Machines Limited.

Schunk's three-year grant acceleration

Schunk GmbH &Co. KG Spann-und Greiftechnik shows 4 grants in 2022–2024 against only 4 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.
