What this shows Powin's Innovation Score is 31.7/100 (39th 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 Powin?

Each dot is one of Powin’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). Powin’s own 17.6 claims/patent is ABOVE the 14.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
