What this shows SK's Innovation Score is 28.5/100 (28th 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 15.4 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where SK's grants concentrate

SK hynix system ic Inc. is a focused PatentsView assignee: 4 CPC subclasses with 85.7% of grants classified under H10D (Inorganic Electric Semiconductor Devices). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2019. By volume, SK sits between Siliconfile Technologies Inc. and Smartrac I.P. B.V..

SK's three-year grant acceleration

SK hynix system ic Inc. shows 3 grants in 2022–2024 against only 7 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.
