What this shows SK's Innovation Score is 62.9/100 (top 2% 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 11.3 claims/patent is at or below the 15.3 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 ie technology Co., Ltd. is a focused PatentsView assignee: 35 CPC subclasses with 45.6% of grants classified under C08J (WORKING-UP; General Processes OF COMPOUNDING; After-treatment NOT Covered BY Subclasses C08b, C08c, C08f, C08g or C08h). Peak complete grant year is 2024 (22 grants) versus a trough of 2 in 2019. By volume, SK sits between Powermat Technologies Ltd. and Tesla Motors, Inc..

SK's three-year grant acceleration

SK ie technology Co., Ltd. shows 49 grants in 2022–2024 against only 15 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.
