Does more volume mean deeper claims for Beijing?

Each dot is one of Beijing’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). Beijing’s own 10.7 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Beijing's grants concentrate

Beijing Tiantan Hospital, Capital Medical University is a focused PatentsView assignee: 10 CPC subclasses with 50% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2024. By volume, Beijing sits between Beewise Technologies Ltd and Benefitfocus.com, Inc..

Beijing's three-year grant acceleration

Beijing Tiantan Hospital, Capital Medical University shows 1 grants in 2022–2024 against only 2 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.
