Where Nihon's grants concentrate

Nihon Superior Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 90.9% of grants classified under B23K (SOLDERING OR UNSOLDERING; WELDING; CLADDING OR PLATING BY SOLDERING OR WELDING; CUTTING BY APPLYING HEAT LOCALLY, e.g. FLAME CUTTING; WORKING BY LASER BEAM). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2016. By volume, Nihon sits between NEW Concepts Development Corporation and Niles Werkzeugmaschinen Gmbh.

Nihon's three-year grant acceleration

Nihon Superior Co., Ltd. shows 3 grants in 2022–2024 against only 3 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.
