What this shows CPK's Innovation Score is 54.5/100 (top 8% 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 CPK?

Each dot is one of CPK’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). CPK’s own 33.3 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where CPK's grants concentrate

CPK Interior Products Inc. is a focused PatentsView assignee: 13 CPC subclasses with 50% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2024. By volume, CPK sits between Corvent Medical, Inc. and CPT Zwei GmbH.

CPK's three-year grant acceleration

CPK Interior Products Inc. shows 3 grants in 2022–2024 against only 0 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.
