What this shows SKC's Innovation Score is 47.9/100 (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.

Where SKC's grants concentrate

SKC Hi-tech & Marketing Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 62.5% of grants classified under G02F (Optical Devices OR Arrangements FOR THE Control OF Light BY Modification OF THE Optical Properties OF THE Media OF THE Elements Involved THEREIN; Non-linear OPTICS; Frequency-changing OF LIGHT; Optica). Peak complete grant year is 2018 (4 grants) versus a trough of 1 in 2019. By volume, SKC sits between Silk Technologies, Ltd. and Skygrid, LLC.

SKC's three-year grant acceleration

SKC Hi-tech & Marketing Co., Ltd. shows 3 grants in 2022–2024 against only 1 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.
