Does more volume mean deeper claims for X-ray?

Each dot is one of X-ray’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). X-ray’s own 17.4 claims/patent is ABOVE the 16.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
