What this shows CTK's Innovation Score is 27.8/100 (25th 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 CTK?

Each dot is one of CTK’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). CTK’s own 5.4 claims/patent is at or below the 17.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where CTK's grants concentrate

CTK Cosmetics Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 50% of grants classified under A45D (Hairdressing OR Shaving Equipment ; Equipment FOR Cosmetics OR Cosmetic Treatments, e.g. FOR Manicuring OR Pedicuring). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2019. By volume, CTK sits between Creating Nano Technologies, Inc. and Calcula Technologies, Inc..

CTK's three-year grant acceleration

CTK Cosmetics Co., Ltd. shows 5 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.
