What this shows Beijing's Innovation Score is 57.2/100 (top 5% 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 13.7 claims/patent is at or below the 15.6 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 Huamei, Inc. is a focused PatentsView assignee: 20 CPC subclasses with 72.7% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2023 (10 grants) versus a trough of 1 in 2019. By volume, Beijing sits between Automotive Lighting Reutlingen GmbH and Bourns, Inc..

Beijing's three-year grant acceleration

Beijing Huamei, Inc. shows 24 grants in 2022–2024 against only 5 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.
