What this shows Yamasa's Innovation Score is 33.0/100 (43rd 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 Yamasa?

Each dot is one of Yamasa’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). Yamasa’s own 9.5 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Yamasa's grants concentrate

Yamasa Corporation is a focused PatentsView assignee: 15 CPC subclasses with 68.8% of grants classified under C07H (SUGARS; Derivatives THEREOF; NUCLEOSIDES; NUCLEOTIDES; Nucleic Acids). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2015. By volume, Yamasa sits between Xockets, Inc. and Zenrin Co., Ltd..

Yamasa's three-year grant acceleration

Yamasa Corporation shows 4 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.
