What this shows Yamato's Innovation Score is 50.6/100 (top 13% 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 6.5 claims/patent is at or below the 16.6 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 Scale Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 79.6% of grants classified under G01G (Weighing). Peak complete grant year is 2016 (11 grants) versus a trough of 1 in 2020. By volume, Yamato sits between Walter AG and Artemis Intelligent Power Limited.

Yamato's three-year grant acceleration

Yamato Scale Co., Ltd. shows 9 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.
