What this shows CK's Innovation Score is 48.0/100 (top 17% 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 12.5 claims/patent is at or below the 13.1 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 Materials LAB Co., Ltd. is a focused PatentsView assignee: 30 CPC subclasses with 87% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2023 (8 grants) versus a trough of 1 in 2017. By volume, CK sits between BÜHLER Motor GMBH and Changzhou Raytech Optronics Co., Ltd..

CK's three-year grant acceleration

CK Materials LAB Co., Ltd. shows 20 grants in 2022–2024 against only 17 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.
