Where Yamamoto's grants concentrate

Yamamoto Chemicals, Inc. is a focused PatentsView assignee: 17 CPC subclasses with 87.5% of grants classified under C09B (Organic Dyes OR Closely-related Compounds FOR Producing Dyes ; , e.g. PIGMENTS; MORDANTS; Lakes). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2016. By volume, Yamamoto sits between Xiber, LLC and Yfc-boneagle Electric Co., Ltd..

Yamamoto's three-year grant acceleration

Yamamoto Chemicals, Inc. 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.
