What this shows Beijing's Innovation Score is 45.2/100 (top 24% 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 10.1 claims/patent is at or below the 15.7 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 Zhong KE SAN Huan Hi-tech Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under H01F (MAGNETS; INDUCTANCES; TRANSFORMERS; Selection OF Materials FOR Their Magnetic Properties). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2020. By volume, Beijing sits between Beijing Edifier Technology Co., Ltd and Beyeonics Surgical Ltd..

Beijing's three-year grant acceleration

Beijing Zhong KE SAN Huan Hi-tech 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.
