Does more volume mean deeper claims for Wolter?

Each dot is one of Wolter’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). Wolter’s own 3.4 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wolter's grants concentrate

Wolter Corp. is a focused PatentsView assignee: 5 CPC subclasses with 12.5% of grants classified under B25D (Percussive Tools). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2019. By volume, Wolter sits between Wind Harvest Intl and Worldheart Corporation.

Wolter's three-year grant acceleration

Wolter Corp. shows 2 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.
