What this shows Otsuka's Innovation Score is 34.4/100 (47th 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 9.7 claims/patent is at or below the 18.3 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 Electronics Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 60% of grants classified under G01J (Measurement OF Intensity, Velocity, Spectral Content, Polarisation, Phase OR Pulse Characteristics OF Infrared, Visible OR Ultraviolet LIGHT; COLORIMETRY; Radiation Pyrometry). Peak complete grant year is 2019 (11 grants) versus a trough of 1 in 2017. By volume, Otsuka sits between New York Blood Center, Inc. and OrthAlign, Inc..

Otsuka's three-year grant acceleration

Otsuka Electronics Co., Ltd. shows 9 grants in 2022–2024 against only 15 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.
