What this shows Kitazato's Innovation Score is 35.5/100 (top 49% 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 Kitazato?

Each dot is one of Kitazato’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). Kitazato’s own 10.2 claims/patent is at or below the 11.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kitazato's grants concentrate

Kitazato Corporation is a focused PatentsView assignee: 12 CPC subclasses with 50% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Kitazato sits between KC IP Holdings, LLC and Kop-coat, Inc..

Kitazato's three-year grant acceleration

Kitazato Corporation shows 5 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.
