What this shows Ranpak's Innovation Score is 50.5/100 (top 13% 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 Ranpak?

Each dot is one of Ranpak’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). Ranpak’s own 11.7 claims/patent is at or below the 13.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ranpak's grants concentrate

Ranpak Corp. is a focused PatentsView assignee: 20 CPC subclasses with 78.5% of grants classified under B31D (Making Articles OF Paper, Cardboard OR Material Worked IN A Manner Analogous TO Paper, NOT Provided FOR IN Subclasses B31b OR B31c). Peak complete grant year is 2022 (14 grants) versus a trough of 4 in 2015. By volume, Ranpak sits between Nissha Co., Ltd. and Shifamed Holdings, LLC.

Ranpak's three-year grant acceleration

Ranpak Corp. shows 34 grants in 2022–2024 against only 18 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.
