What this shows Utsunomiya's Innovation Score is 35.2/100 (top 50% 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 Utsunomiya?

Each dot is one of Utsunomiya’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). Utsunomiya’s own 10.2 claims/patent is at or below the 16.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Utsunomiya's grants concentrate

Utsunomiya University is a focused PatentsView assignee: 21 CPC subclasses with 36.8% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2016. By volume, Utsunomiya sits between Umarex USA, Inc. and Unified Compliance Framework (Network Frontiers).

Utsunomiya's three-year grant acceleration

Utsunomiya University shows 3 grants in 2022–2024 against only 8 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.
