Where Kazusa's grants concentrate

Kazusa DNA Research Institute is a focused PatentsView assignee: 19 CPC subclasses with 50% of grants classified under C07K (Peptides). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2017. By volume, Kazusa sits between Kanagawa Academy of Science and Technology and Kerry Luxembourg S.á.r.l..

Kazusa's three-year grant acceleration

Kazusa DNA Research Institute shows 1 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.
