Does more volume mean deeper claims for Liberty?

Each dot is one of Liberty’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). Liberty’s own 12.5 claims/patent is at or below the 13.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
