What this shows Beijing's Innovation Score is 27.6/100 (24th percentile 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 13.0 claims/patent is ABOVE the 11.1 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 Red-sea Tech Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 87.5% of grants classified under G01F (Measuring Volume, Volume Flow, Mass Flow OR Liquid LEVEL; Metering BY Volume). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Beijing sits between Beijing Institute OF Nanoenergy AND Nanosystems and Berry Film Products Company, Inc..
Beijing's three-year grant acceleration
Beijing Red-sea Tech Co., Ltd. shows 1 grants in 2022–2024 against only 3 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.
