Does more volume mean deeper claims for Zhuhai?
Each dot is one of Zhuhai’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). Zhuhai’s own 13.7 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Zhuhai's grants concentrate
Zhuhai Ninestar Management Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 85% of grants classified under B41J (TYPEWRITERS; Selective Printing Mechanisms, i.e. Mechanisms Printing Otherwise Than From A FORME; Correction OF Typographical Errors). Peak complete grant year is 2016 (6 grants) versus a trough of 1 in 2018. By volume, Zhuhai sits between Zehnder Group International AG and i-Lumen Scientific, Inc..
Zhuhai's three-year grant acceleration
Zhuhai Ninestar Management Co., Ltd. shows 1 grants in 2022–2024 against only 0 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.
