What this shows Ninestar's Innovation Score is 31.1/100 (37th percentile 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 Ninestar?

Each dot is one of Ninestar’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). Ninestar’s own 15.8 claims/patent is ABOVE the 14.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ninestar's grants concentrate

Ninestar Corporation is a focused PatentsView assignee: 2 CPC subclasses with 90.9% of grants classified under G03G (ELECTROGRAPHY; ELECTROPHOTOGRAPHY; Magnetography). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2018. By volume, Ninestar sits between National Kaohsiung University OF Science AND Technology and Nottingham Trent University.

Ninestar's three-year grant acceleration

Ninestar Corporation shows 7 grants in 2022–2024 against only 8 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.
