Does more volume mean deeper claims for Vitro?
Each dot is one of Vitro’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). Vitro’s own 16.7 claims/patent is at or below the 18.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
