What this shows Sengled's Innovation Score is 30.6/100 (35th 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 Sengled?

Each dot is one of Sengled’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). Sengled’s own 11.1 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sengled's grants concentrate

Sengled Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 50% 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 2019 (4 grants) versus a trough of 1 in 2023. By volume, Sengled sits between Semiconductor Technologies & Instruments PTE Ltd and Shenzhen Aokang Technology Co., Ltd..

Sengled's three-year grant acceleration

Sengled Co., Ltd. shows 4 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.
