What this shows Hiroshima's Innovation Score is 57.6/100 (top 5% 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 Hiroshima?

Each dot is one of Hiroshima’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). Hiroshima’s own 10.1 claims/patent is at or below the 13.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
