What this shows Otsuka's Innovation Score is 31.4/100 (38th 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 Otsuka?

Each dot is one of Otsuka’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). Otsuka’s own 7.9 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Otsuka's grants concentrate

Otsuka Techno Corporation is a focused PatentsView assignee: 12 CPC subclasses with 41.7% of grants classified under A61N (ELECTROTHERAPY; MAGNETOTHERAPY; Radiation THERAPY; Ultrasound Therapy). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2018. By volume, Otsuka sits between Opterna AM, Inc. and OZ Optics Ltd..

Otsuka's three-year grant acceleration

Otsuka Techno Corporation shows 5 grants in 2022–2024 against only 6 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.
