Where Kitamura's grants concentrate

Kitamura Machinery Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 54.5% of grants classified under G05B (CONTROL OR REGULATING SYSTEMS IN GENERAL; FUNCTIONAL ELEMENTS OF SUCH SYSTEMS; MONITORING OR TESTING ARRANGEMENTS FOR SUCH SYSTEMS OR ELEMENTS). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Kitamura sits between KH Neochem Co., Ltd. and KNOW Systems Corp.

Kitamura's three-year grant acceleration

Kitamura Machinery Co., Ltd. shows 4 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.
