What this shows Peking's Innovation Score is 35.1/100 (top 50% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Peking?

Each dot is one of Peking’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). Peking’s own 8.7 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Peking's grants concentrate

Peking University School OF Stomatology is a focused PatentsView assignee: 7 CPC subclasses with 71.4% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2019. By volume, Peking sits between Pd-ld, Inc. and Perigen Inc..

Peking's three-year grant acceleration

Peking University School OF Stomatology shows 4 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.
