What this shows Beijing's Innovation Score is 56.0/100 (top 6% 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 5.5 claims/patent is at or below the 17.7 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 Roborock Technology Co., Ltd. is a focused PatentsView assignee: 23 CPC subclasses with 27.4% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2023 (32 grants) versus a trough of 3 in 2021. By volume, Beijing sits between Wix.com Ltd. and Daido Steel Co., Ltd..

Beijing's three-year grant acceleration

Beijing Roborock Technology Co., Ltd. shows 63 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.
