What this shows CK's Innovation Score is 32.0/100 (40th percentile 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 CK?

Each dot is one of CK’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). CK’s own 10.8 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where CK's grants concentrate

CK Manufacturing, LLC is a focused PatentsView assignee: 7 CPC subclasses with 60% of grants classified under F42B (Explosive Charges, e.g. FOR Blasting, Fireworks, Ammunition). By volume, CK sits between Ciris Energy, Inc and Clarabridge, Inc..

CK's three-year grant acceleration

CK Manufacturing, LLC shows 3 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.
