What this shows Duck's Innovation Score is 33.0/100 (43rd percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Duck?

Each dot is one of Duck’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). Duck’s own 12.3 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Duck's grants concentrate

Duck Yang Industry Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 42.9% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2018. By volume, Duck sits between DreamBig Semiconductor, Inc. and Dwellwell Analytics, Inc..

Duck's three-year grant acceleration

Duck Yang Industry Co., Ltd. shows 3 grants in 2022–2024 against only 3 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.
