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.
