Where Sungwoo's grants concentrate

Sungwoo Hitech Co., Ltd. is a focused PatentsView assignee: 34 CPC subclasses with 30.6% of grants classified under B21D (Working OR Processing OF Sheet Metal OR Metal Tubes, Rods OR Profiles Without Essentially Removing MATERIAL; Punching Metal). Peak complete grant year is 2017 (16 grants) versus a trough of 1 in 2016. By volume, Sungwoo sits between Shanghaitech University and TRON—Translationale Onkologie an der Universitätsmedizin der Johannes Gutenberg-Universität Mainz.

Sungwoo's three-year grant acceleration

Sungwoo Hitech Co., Ltd. shows 12 grants in 2022–2024 against only 11 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.
