Does more volume mean deeper claims for West?

Each dot is one of West’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). West’s own 11.5 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where West's grants concentrate

West China Hospital, Sichuan University is a focused PatentsView assignee: 21 CPC subclasses with 50% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2015. By volume, West sits between Velico Medical Inc. and Wuhan University OF Science AND Technology.

West's three-year grant acceleration

West China Hospital, Sichuan University shows 7 grants in 2022–2024 against only 7 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
