What this shows Iwaki's Innovation Score is 29.8/100 (32nd 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 Iwaki?

Each dot is one of Iwaki’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). Iwaki’s own 10.2 claims/patent is ABOVE the 9.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Iwaki's grants concentrate

Iwaki Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 69.2% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2016. By volume, Iwaki sits between Iriver Limited and Ideal Innovations, Inc..

Iwaki's three-year grant acceleration

Iwaki Co., Ltd. shows 3 grants in 2022–2024 against only 7 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.
