What this shows Yamato's Innovation Score is 21.7/100 (9th 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 Yamato?

Each dot is one of Yamato’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). Yamato’s own 4.9 claims/patent is at or below the 7.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yamato's grants concentrate

Yamato Corporation is a focused PatentsView assignee: 7 CPC subclasses with 28.6% of grants classified under B65B (Machines, Apparatus OR Devices FOR, OR Methods OF, Packaging Articles OR MATERIALS; Unpacking). By volume, Yamato sits between Yungjin Pharm. Co., Ltd. and Yisheng Biopharma (Singapore) PTE Ltd.

Yamato's three-year grant acceleration

Yamato Corporation shows 1 grants in 2022–2024 against only 3 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.
