Does more volume mean deeper claims for Kyoshin?

Each dot is one of Kyoshin’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). Kyoshin’s own 2.8 claims/patent is at or below the 8.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
