Does more volume mean deeper claims for Nanotheta?

Each dot is one of Nanotheta’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). Nanotheta’s own 9.1 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
