What this shows SK's Innovation Score is 52.8/100 (top 10% 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 13.3 claims/patent is at or below the 16.1 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 Enpulse Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 75% of grants classified under B24B (Machines, Devices, OR Processes FOR Grinding OR Polishing ; Dressing OR Conditioning OF Abrading SURFACES; Feeding OF Grinding, Polishing, OR Lapping Agents). Peak complete grant year is 2024 (13 grants) versus a trough of 7 in 2023. By volume, SK sits between Shenzhen NEW Degree Technology Co., Ltd. and Span Tech LLC.
SK's three-year grant acceleration
SK Enpulse Co., Ltd. shows 20 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.
