What this shows Nippon's Innovation Score is 46.4/100 (top 21% 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 Nippon?

Each dot is one of Nippon’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). Nippon’s own 11.5 claims/patent is at or below the 15.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
