What this shows SK's Innovation Score is 44.5/100 (top 25% 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 9.3 claims/patent is at or below the 10.8 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 Nexilis Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2022 (4 grants) versus a trough of 2 in 2023. By volume, SK sits between Silitek Electronics (DONGGUAN) Co., Ltd and SKY Motion Research, ULC.

SK's three-year grant acceleration

SK Nexilis 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.
