What this shows Kazusa's Innovation Score is 33.6/100 (45th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Kazusa?

Each dot is one of Kazusa’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Kazusa’s own 14.0 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

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.
