What this shows Saitama's Innovation Score is 35.6/100 (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 Saitama?

Each dot is one of Saitama’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). Saitama’s own 10.1 claims/patent is ABOVE the 9.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Saitama's grants concentrate

Saitama Medical University is a focused PatentsView assignee: 18 CPC subclasses with 60% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2015. By volume, Saitama sits between Suzhou Oriental Semiconductor Co., Ltd. and Shanghai Biren Technology Co., Ltd.

Saitama's three-year grant acceleration

Saitama Medical University shows 5 grants in 2022–2024 against only 10 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.
