Does more volume mean deeper claims for Ningbo?

Each dot is one of Ningbo’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). Ningbo’s own 7.6 claims/patent is ABOVE the 1.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ningbo's grants concentrate

Ningbo Hongdu Model Plastics Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 80% of grants classified under A01K (Animal HUSBANDRY; AVICULTURE; APICULTURE; PISCICULTURE; FISHING; Rearing OR Breeding Animals, NOT Otherwise Provided FOR; NEW Breeds OF Animals). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2022. By volume, Ningbo sits between Ningbo Gongyi Industry and Trade Co., Ltd. and Ningbo Langyan Technology Co., Ltd..

Ningbo's three-year grant acceleration

Ningbo Hongdu Model Plastics Co., Ltd. shows 5 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.
