What this shows Jichi's Innovation Score is 43.0/100 (top 29% 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 Jichi?

Each dot is one of Jichi’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). Jichi’s own 11.7 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Jichi's grants concentrate

Jichi Medical University is a focused PatentsView assignee: 20 CPC subclasses with 45.5% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2017. By volume, Jichi sits between Japan Technological Research Association OF Artificial Photosynthetic Chemical Process and KCC Corporation.

Jichi's three-year grant acceleration

Jichi Medical University shows 7 grants in 2022–2024 against only 5 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.
