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 12.2 claims/patent is ABOVE the 3.8 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 Major Draft Beer Equipment Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 77.8% of grants classified under B67D (Dispensing, Delivering OR Transferring Liquids, NOT Otherwise Provided FOR). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2019. By volume, Ningbo sits between Nimbus Group GmbH and Nissui Corporation.

Ningbo's three-year grant acceleration

Ningbo Major Draft Beer Equipment Co., Ltd. shows 3 grants in 2022–2024 against only 6 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.
