What this shows Fujitsu's Innovation Score is 45.5/100 (top 23% 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 Fujitsu?

Each dot is one of Fujitsu’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). Fujitsu’s own 12.0 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
