Does more volume mean deeper claims for Sirona?

Each dot is one of Sirona’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). Sirona’s own 20.7 claims/patent is ABOVE the 11.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
