Where NAC's grants concentrate

NAC International Inc. is a focused PatentsView assignee: 7 CPC subclasses with 85.7% 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 2022 (3 grants) versus a trough of 1 in 2015. By volume, NAC sits between Morega Systems Inc. and Nanogrid Limited.

NAC's three-year grant acceleration

NAC International Inc. shows 7 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.
