What this shows Ichikoh's Innovation Score is 50.6/100 (top 13% 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 Ichikoh?

Each dot is one of Ichikoh’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). Ichikoh’s own 8.4 claims/patent is at or below the 12.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
