What this shows SK's Innovation Score is 47.8/100 (top 18% 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 SK?

Each dot is one of SK’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). SK’s own 11.9 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SK's grants concentrate

SK microworks solutions Co., Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 55.6% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2023 (5 grants) versus a trough of 3 in 2024. By volume, SK sits between Sistemas TÉCNICOS DE Encofrados, S.A. and SLD Technology, Inc..

SK's three-year grant acceleration

SK microworks solutions Co., Ltd. shows 8 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.
