Where TN's grants concentrate

TN International is a focused PatentsView assignee: 15 CPC subclasses with 100% of grants classified under G21F (Protection Against X-radiation, Gamma Radiation, Corpuscular Radiation OR Particle BOMBARDMENT; Treating Radioactively Contaminated MATERIAL; Decontamination Arrangements Therefor). Peak complete grant year is 2015 (5 grants) versus a trough of 2 in 2016. By volume, TN sits between THE Korea Development Bank and Topy Kogyo Kabushiki Kaisha.

TN's three-year grant acceleration

TN International shows 2 grants in 2022–2024 against only 6 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.
