What this shows Beijing's Innovation Score is 61.5/100 (top 3% 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 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 7.3 claims/patent is at or below the 15.2 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 Jiaotong University is a focused PatentsView assignee: 45 CPC subclasses with 20.8% of grants classified under B61L (Guiding Railway TRAFFIC; Ensuring THE Safety OF Railway Traffic). Peak complete grant year is 2024 (10 grants) versus a trough of 1 in 2021. By volume, Beijing sits between Beneq OY and Cognizant Technology Solutions U.S. Corporation.

Beijing's three-year grant acceleration

Beijing Jiaotong University shows 22 grants in 2022–2024 against only 6 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.
