What this shows Dong's Innovation Score is 27.0/100 (22nd 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 Dong?

Each dot is one of Dong’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). Dong’s own 5.8 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dong's grants concentrate

Dong Guan Bright Yinhuey Lighting Co., Ltd. China is a focused PatentsView assignee: 13 CPC subclasses with 55.6% of grants classified under F21V (Functional Features OR Details OF Lighting Devices OR Systems THEREOF; Structural Combinations OF Lighting Devices With Other Articles, NOT Otherwise Provided FOR). Peak complete grant year is 2019 (9 grants) versus a trough of 1 in 2017. By volume, Dong sits between Direct Supply, Inc. and Dreame Innovation Technology (Suzhou) Co., Ltd..

Dong's three-year grant acceleration

Dong Guan Bright Yinhuey Lighting Co., Ltd. China shows 1 grants in 2022–2024 against only 11 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.
