What this shows Iida's Innovation Score is 28.7/100 (28th 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 Iida?

Each dot is one of Iida’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). Iida’s own 8.8 claims/patent is at or below the 8.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Iida's grants concentrate

Iida Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 40% of grants classified under F16J (Pistons ; CYLINDERS; Sealings). By volume, Iida sits between Ifom —FONDAZIONE Istituto Firc DI Oncologia Molecolare and Ildong Pharm Co., Ltd..

Iida's three-year grant acceleration

Iida Co., Ltd. shows 2 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.
