What this shows SK's Innovation Score is 29.1/100 (29th percentile 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 7.5 claims/patent is at or below the 11.2 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 Signet Inc. is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under Y02T (Climate Change Mitigation Technologies Related TO Transportation). By volume, SK sits between Sintratec AG and Skyla Corporation Hsinchu Science Park Branch.

SK's three-year grant acceleration

SK Signet Inc. shows 1 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.
