Where Nippon's grants concentrate

Nippon Steel SG Wire Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under C21D (Modifying THE Physical Structure OF Ferrous METALS; General Devices FOR Heat Treatment OF Ferrous OR Non-ferrous Metals OR ALLOYS; Making Metal Malleable, e.g. BY Decarburisation OR Tempering). By volume, Nippon sits between Nippon Leakless Industry Co., Ltd. and NJS Co., Ltd..

Nippon's three-year grant acceleration

Nippon Steel SG Wire Co., Ltd. shows 3 grants in 2022–2024 against only 0 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.
