What this shows Igisu's Innovation Score is 44.9/100 (top 24% 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 Igisu?

Each dot is one of Igisu’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). Igisu’s own 15.4 claims/patent is at or below the 18.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Igisu's grants concentrate

Igisu Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2017. By volume, Igisu sits between Iceberg Luxembourg S.A.R.L. and Imago Biosciences, Inc..

Igisu's three-year grant acceleration

Igisu Co., Ltd. shows 3 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.
