What this shows Astellas's Innovation Score is 45.9/100 (top 22% 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 Astellas?

Each dot is one of Astellas’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). Astellas’s own 15.7 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Astellas's grants concentrate

Astellas Institute for Regenerative Medicine is a focused PatentsView assignee: 11 CPC subclasses with 82.9% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2017 (8 grants) versus a trough of 1 in 2020. By volume, Astellas sits between Aileron Therapeutics, Inc. and Beijing Xiaomi Intelligent Technology Co., Ltd..

Astellas's three-year grant acceleration

Astellas Institute for Regenerative Medicine shows 13 grants in 2022–2024 against only 7 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.
