Does more volume mean deeper claims for Ching?

Each dot is one of Ching’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). Ching’s own 6.6 claims/patent is at or below the 12.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ching's grants concentrate

Ching Feng Home Fashions Co., Ltd. is a focused PatentsView assignee: 15 CPC subclasses with 90% of grants classified under E06B (Fixed OR Movable Closures FOR Openings IN Buildings, Vehicles, Fences OR Like Enclosures IN General, e.g. Doors, Windows, Blinds, Gates). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2023. By volume, Ching sits between Brose Fahrzeugteile GmbH & Co. KG, Wuerzburg and CUB Elecparts Inc..

Ching's three-year grant acceleration

Ching Feng Home Fashions Co., Ltd. shows 10 grants in 2022–2024 against only 9 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.
