Does more volume mean deeper claims for Xi'an?
Each dot is one of Xi'an’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). Xi'an’s own 8.1 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
How Xi'an's grant cadence moved
