Does more volume mean deeper claims for Proampac?

Each dot is one of Proampac’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). Proampac’s own 15.3 claims/patent is ABOVE the 14.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Proampac's grants concentrate

ProAmpac Holdings Inc. is a focused PatentsView assignee: 9 CPC subclasses with 47.4% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2017. By volume, Proampac sits between Pop Test Oncology LLC and Q (Cue) Ltd..

Proampac's three-year grant acceleration

ProAmpac Holdings Inc. shows 8 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.
