Does more volume mean deeper claims for Taisho?

Each dot is one of Taisho’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). Taisho’s own 12.8 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Taisho's grants concentrate

Taisho Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 91.3% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2015 (8 grants) versus a trough of 1 in 2020. By volume, Taisho sits between Syntiant Corp. and Thales DIS AIS Deutschland GMBH.

Taisho's three-year grant acceleration

Taisho Pharmaceutical Co., Ltd. shows 1 grants in 2022–2024 against only 4 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.
