Does more volume mean deeper claims for Ninghai?

Each dot is one of Ninghai’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). Ninghai’s own 7.4 claims/patent is ABOVE the 7.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ninghai's grants concentrate

Ninghai Jiarun Hardware Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 60% of grants classified under A47C (CHAIRS; SOFAS; Beds). By volume, Ninghai sits between Ningbo Qtop Import & Export Co., Ltd. and Noction, Inc..

Ninghai's three-year grant acceleration

Ninghai Jiarun Hardware 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.
