What this shows Beijing's Innovation Score is 40.9/100 (top 34% 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 11.4 claims/patent is ABOVE the 9.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Beijing's grants concentrate

Beijing Sevenstar Flow Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under G05D (Systems FOR Controlling OR Regulating Non-electric Variables). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2018. By volume, Beijing sits between Beijing Hengxiang Hongye Foundation Reinforcement Technology Co., Ltd. and Beijing Unicorn Technology Co., Ltd..

Beijing's three-year grant acceleration

Beijing Sevenstar Flow Co., Ltd. shows 3 grants in 2022–2024 against only 1 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.
