What this shows SK's Innovation Score is 52.9/100 (top 9% 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 15.8 claims/patent is ABOVE the 15.7 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 Materials JNC Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 100% of grants classified under H10K (Organic Electric Solid-state Devices). Peak complete grant year is 2023 (9 grants) versus a trough of 2 in 2021. By volume, SK sits between Shenzhen Super TOP Innovation Technology Limited and Sphingotec GMBH.

SK's three-year grant acceleration

SK Materials JNC Co., Ltd. shows 16 grants in 2022–2024 against only 2 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.
