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 12.8 claims/patent is ABOVE the 11.4 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 Uni-star Inspection Technology Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 80% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2021 (3 grants) versus a trough of 2 in 2022. By volume, Beijing sits between Beijing Ruijian Gaoke Biotechnology Co., Ltd. and Belgicactus B.V.B.A..

Beijing's three-year grant acceleration

Beijing Uni-star Inspection Technology Co., Ltd. shows 2 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.
