Does more volume mean deeper claims for Nanchang?
Each dot is one of Nanchang’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). Nanchang’s own 18.3 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Nanchang's grants concentrate
Nanchang O-film Bio-identification Technology Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 93.8% of grants classified under G06V (Image OR Video Recognition OR Understanding). Peak complete grant year is 2019 (12 grants) versus a trough of 1 in 2022. By volume, Nanchang sits between Monk Akarshala Design Private Limited and Navy Federal Credit Union.
Nanchang's three-year grant acceleration
Nanchang O-film Bio-identification Technology Co., Ltd. shows 1 grants in 2022–2024 against only 12 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.
