Where Kubota's grants concentrate

Kubota Manufacturing Corporation is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under B04B (Centrifuges). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2019. By volume, Kubota sits between Kruger Inc. and KUK IL Inntot Co. , Ltd..

Kubota's three-year grant acceleration

Kubota Manufacturing Corporation shows 1 grants in 2022–2024 against only 4 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.
