Where Nitto's grants concentrate

Nitto Kasei Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 57.1% of grants classified under C09D (Coating Compositions, e.g. Paints, Varnishes OR LACQUERS; Filling PASTES; Chemical Paint OR INK REMOVERS; INKS; Correcting FLUIDS; WOODSTAINS; Pastes OR Solids FOR Colouring OR PRINTING; USE OF Materi). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2018. By volume, Nitto sits between Nishina Industrial Co., Ltd. and No-knob, LLC.

Nitto's three-year grant acceleration

Nitto Kasei Co., Ltd. shows 1 grants in 2022–2024 against only 1 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.
