Where Sungilturbine's grants concentrate

Sungilturbine Co., Ltd is a focused PatentsView assignee: 9 CPC subclasses with 50% of grants classified under C10L (Fuels NOT Otherwise Provided FOR; Natural GAS; Synthetic Natural GAS Obtained BY Processes NOT Covered BY Subclasses C10g OR C10K; Liquified Petroleum GAS; USE OF Additives TO Fuels OR FIRES; Fire-lig). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2018. By volume, Sungilturbine sits between SUN Electronic Industries Corp. and Sunsea Telecommunications Co., Ltd..

Sungilturbine's three-year grant acceleration

Sungilturbine Co., Ltd shows 1 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.
