Does more volume mean deeper claims for Empi?

Each dot is one of Empi’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). Empi’s own 17.3 claims/patent is ABOVE the 17.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
