What this shows Giken's Innovation Score is 46.2/100 (top 21% 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 Giken?

Each dot is one of Giken’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). Giken’s own 8.6 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Giken's grants concentrate

Giken Ltd. is a focused PatentsView assignee: 13 CPC subclasses with 50% of grants classified under E02D (FOUNDATIONS; EXCAVATIONS; Embankments ; Underground OR Underwater Structures). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2023. By volume, Giken sits between Gencurix Inc. and Global Energy Interconnection Research Institute Co., Ltd..

Giken's three-year grant acceleration

Giken Ltd. shows 6 grants in 2022–2024 against only 2 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.
