What this shows Beijing's Innovation Score is 35.3/100 (top 50% 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 11.8 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 Tongmei Xtal Technology Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 62.5% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2017. By volume, Beijing sits between Beijing Med-zenith Medical Scientific Corporation Limited and Besins Healthcare Luxembourg Sarl.

Beijing's three-year grant acceleration

Beijing Tongmei Xtal Technology Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
