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 12.4 claims/patent is ABOVE the 11.9 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 GAS Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 88.9% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2019. By volume, SK sits between Sinphar Pharmaceutical Co., Ltd. and SKF Canada Limited.

SK's three-year grant acceleration

SK GAS Co., Ltd. shows 4 grants in 2022–2024 against only 5 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.
