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 8.3 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ningbo's grants concentrate

Ningbo Fotile Kitchen Ware Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 58.6% of grants classified under F24C (Domestic Stoves OR Ranges ; Details OF Domestic Stoves OR Ranges, OF General Application). Peak complete grant year is 2023 (8 grants) versus a trough of 1 in 2018. By volume, Ningbo sits between Natural Gas Solutions North America, LLC and ODK Technology PTE. Ltd..

Ningbo's three-year grant acceleration

Ningbo Fotile Kitchen Ware Co., Ltd. shows 16 grants in 2022–2024 against only 10 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.
