Does more volume mean deeper claims for Wulftec?

Each dot is one of Wulftec’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). Wulftec’s own 15.0 claims/patent is ABOVE the 8.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Wulftec's grants concentrate

Wulftec International Inc. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under B65B (Machines, Apparatus OR Devices FOR, OR Methods OF, Packaging Articles OR MATERIALS; Unpacking). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2018. By volume, Wulftec sits between Wota Corp. and WaisMed Ltd..

Wulftec's three-year grant acceleration

Wulftec International Inc. shows 4 grants in 2022–2024 against only 1 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.
