What this shows Senju's Innovation Score is 41.9/100 (top 32% 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 Senju?

Each dot is one of Senju’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). Senju’s own 12.2 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Senju's grants concentrate

Senju Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 16 CPC subclasses with 84.1% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (6 grants) versus a trough of 2 in 2021. By volume, Senju sits between Reliant Immune Diagnostics, Inc. and Sirona Dental Systems GmbH.

Senju's three-year grant acceleration

Senju Pharmaceutical Co., Ltd. shows 12 grants in 2022–2024 against only 11 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.
