What this shows Clean's Innovation Score is 27.3/100 (23rd 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 Clean?

Each dot is one of Clean’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). Clean’s own 18.0 claims/patent is ABOVE the 17.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
