What this shows Shiga's Innovation Score is 30.3/100 (34th 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 Shiga?

Each dot is one of Shiga’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). Shiga’s own 11.4 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shiga's grants concentrate

Shiga University OF Medical Science is a focused PatentsView assignee: 15 CPC subclasses with 50% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2019. By volume, Shiga sits between Shenzhen Vimai Technology Co., Limited and Sicam S.R.L..

Shiga's three-year grant acceleration

Shiga University OF Medical Science 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.
