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 15.3 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
