What this shows BCD's Innovation Score is 32.4/100 (41st 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 BCD?

Each dot is one of BCD’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). BCD’s own 18.5 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
