What this shows Yamato's Innovation Score is 28.0/100 (26th 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 6.7 claims/patent is at or below the 8.3 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 Protec Corporation is a focused PatentsView assignee: 9 CPC subclasses with 83.3% of grants classified under A62D (Chemical Means FOR Extinguishing Fires OR FOR Combating OR Protecting Against Harmful Chemical AGENTS; Chemical Materials FOR USE IN Breathing Apparatus). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2024. By volume, Yamato sits between Xindao (Shanghai) Co., Ltd. and Yejia Optical Technology (GUANGDONG) Corporation.

Yamato's three-year grant acceleration

Yamato Protec Corporation shows 1 grants in 2022–2024 against only 0 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.
