What this shows K-lab's Innovation Score is 25.7/100 (18th 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 K-lab?

Each dot is one of K-lab’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). K-lab’s own 4.8 claims/patent is at or below the 8.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where K-lab's grants concentrate

K-lab Corp. is a focused PatentsView assignee: 8 CPC subclasses with 20% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2015. By volume, K-lab sits between K Fresh Co., Ltd and K.K. Sun Metalon.

K-lab's three-year grant acceleration

K-lab Corp. shows 1 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.
