What this shows Yoshino's Innovation Score is 52.8/100 (top 10% 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 Yoshino?

Each dot is one of Yoshino’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). Yoshino’s own 11.3 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 Yoshino's grants concentrate

Yoshino Gypsum Co., Ltd. is a focused PatentsView assignee: 42 CPC subclasses with 39.2% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2017 (9 grants) versus a trough of 2 in 2019. By volume, Yoshino sits between ViiV Healthcare UK (No.5) Limited and Alfred KÄRCHER SE & Co. KG.

Yoshino's three-year grant acceleration

Yoshino Gypsum Co., Ltd. shows 17 grants in 2022–2024 against only 12 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.
