Where FUSO's grants concentrate

FUSO Chemical Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 90% of grants classified under C01B (NON-METALLIC ELEMENTS; COMPOUNDS THEREOF; ; METALLOIDS OR COMPOUNDS THEREOF NOT COVERED BY SUBCLASS C01C). By volume, FUSO sits between Fujidenolo Co., Ltd. and Feellife Health Inc..

FUSO's three-year grant acceleration

FUSO Chemical Co., Ltd. shows 2 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.
