Does more volume mean deeper claims for Duckyang?

Each dot is one of Duckyang’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). Duckyang’s own 14.0 claims/patent is ABOVE the 11.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Duckyang's grants concentrate

Duckyang Ind. Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 90% of grants classified under B60J (Windows, Windscreens, Non-fixed Roofs, Doors, OR Similar Devices FOR VEHICLES; Removable External Protective Coverings Specially Adapted FOR Vehicles). Peak complete grant year is 2021 (4 grants) versus a trough of 2 in 2020. By volume, Duckyang sits between Dri-Eaz Products, Inc. and E.M.W. Energy Co., Ltd..

Duckyang's three-year grant acceleration

Duckyang Ind. 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.
