What this shows Shimizu's Innovation Score is 53.6/100 (top 9% 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 Shimizu?

Each dot is one of Shimizu’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). Shimizu’s own 8.6 claims/patent is at or below the 10.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shimizu's grants concentrate

Shimizu Corporation is a focused PatentsView assignee: 30 CPC subclasses with 23.1% of grants classified under E04G (SCAFFOLDING; FORMS; SHUTTERING; Building Implements OR Aids, OR Their USE; Handling Building Materials ON THE SITE; Repairing, Breaking-up OR Other Work ON Existing Buildings). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2015. By volume, Shimizu sits between Shenzhen Silver Star Intelligent Technology Co., Ltd. and Sika Dr. Siebert & Kühn GmbH & Co. KG.

Shimizu's three-year grant acceleration

Shimizu Corporation shows 7 grants in 2022–2024 against only 1 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.
